CHI A) B) C) D) Ans: Which of the following groups would be best 1. served by the development of a scientific base for nursing practice? Nursing administrators Practicing nurses Nurses' clients Health care policymakers C Feedback: Nursing research is systematic inquiry designed to develop trustworthy evidence about issues of importance to nurses and their clients. Nurse leaders recognize the need to base specific nursing decisions on evidence indicating that the decisions are clinically appropriate, cost-effective, and result in positive client outcomes. Although all of the people listed would benefit from the development of a scientific base for nursing practice, ultimately it is the clients themselves who would most benefit, as they would then receive the most appropriate and most effective care. 2. A) B) C) D) Ans: An especially important goal for the nursing profession is to do which of the following? Conduct research to better understand the context of nursing practice Establish a solid base of evidence for practice through disciplined research Document the role nursing serves in society Establish research priorities B Feedback: Nurses are increasingly expected to understand and undertake research and to base their practice on evidence from research. Evidence-based practice is the use of the best evidence in making patient care decisions and typically comes from research conducted by nurses and other health-care professionals. All of the other answers are possible goals for the nursing profession, but none is as important as establishing evidence for practice.

Which of the following is a fundamental 3. belief of those who hold to the constructivist paradigm? A fixed reality exists in nature for humans to understand The nature of reality has changed over time Reality is multiply constructed and multiply interpreted by humans Reality cannot be studied empirically C Feedback: In the constructivist paradigm, it is assumed that reality is not a fixed entity but is rather a construction of human minds—and thus “truth” is a composite of multiple constructions of reality. However, constructivists do believe that reality can be studied empirically. Belief in a fixed reality that exists in nature for humans to understand would be an example of a positivist belief, not a constructivist one. The constructivist belief does not hold so much that the nature of reality has changed over time as that it has always been constructed by human minds. Which of the following is a fundamental 4. belief of those who hold to the positivist paradigm?

The researcher is objective and independent of those being studied The researcher cannot interact with those being studied The researcher instructs those being studied to be objective in providing information The distance between the researcher and those being researched is minimized to enhance the interactive process A Feedback: In the positivist paradigm, it is assumed that there is an objective reality and that natural phenomena are regular and orderly. In the constructivist paradigm, it is assumed that reality is not a fixed entity but is rather a construction of human minds—and thus “truth” is a composite of multiple constructions of reality. Which of the following attributes is least 5. characteristic of the traditional scientific method? Control over external factors Systematic measurement and observation of natural phenomena Testing of hunches deduced from theory or prior research Emphasis on a holistic view of a phenomenon, studied in a rich context D Feedback: Quantitative research (associated with positivism) involves the collection and analysis of numeric information. Quantitative research is typically conducted within the traditional scientific method, which is systematic and controlled. Quantitative researchers base their findings on empirical evidence (evidence collected by way of the human senses) and strive for generalizability beyond a single setting or situation. Constructivist researchers emphasize understanding human experience as it is lived through the collection and analysis of subjective, narrative materials using flexible procedures; this paradigm is associated with qualitative research.

Empiricism refers to which of the following? Making generalizations from specific observations Articulating a study purpose in terms of an appropriate classification system Gathering evidence about real-world phenomena through the senses Verifying the assumptions on which the study was based C Feedback: Empiricism is gathering and analyzing evidence through their senses. Quantitative research involves the collection and analysis of numeric information. Quantitative research is typically conducted within the traditional scientific method, which is systematic and controlled. Quantitative researchers base their findings on empirical evidence and strive for generalizability beyond a single setting or situation.

Constructivist researchers emphasize understanding human experience as it is lived through the collection and analysis of subjective, narrative materials using flexible procedures; this paradigm is associated with qualitative research. Which of the following limits the capacity of 8. the scientific method to answer questions about humans? The necessity of departing from traditional beliefs The difficulty of accurately measuring complex human traits The lack of funding for research The shortage of theories about human behavior B Feedback: Nursing research focuses on human beings, who are inherently complicated and diverse. The traditional scientific method typically focuses on a relatively small aspect of human experiences in a single study. Complexities tend to be controlled and, if possible, eliminated rather than studied directly, and this narrowness of focus can sometimes obscure insights. C) The lack of funding for research The shortage of theories about human behavior B Feedback: Nursing research focuses on human beings, who are inherently complicated and diverse.

A) B) C) D) Ans: The classic scientific method has its intellectual roots in which of the following? Positivism Determinism Constructivism Empiricism A Feedback: In the positivist paradigm, it is assumed that there is an objective reality and that natural phenomena are regular and orderly. The related assumption of determinism refers to the belief that phenomena result from prior causes and are not haphazard. In the constructivist paradigm, it is assumed that reality is not a fixed entity but is rather a construction of human minds—and thus “truth” is a composite of multiple constructions of reality. Although the word empiricism has come to be allied with the classic scientific method, researchers in both traditions gather and analyze evidence empirically, that is, through their senses. Constructivist qualitative research typically does which of the following? Involves deductive processes Attempts to control the research context to better understand the phenomenon being studied Involves gathering narrative, subjective materials Focuses on numeric information C Feedback: In the constructivist paradigm, it is assumed that reality is not a fixed entity but is rather a B) C) D) Ans: A) B) C) D) Ans: A) B) C) D) Attempts to control the research context to better understand the phenomenon being studied Involves gathering narrative, subjective materials Focuses on numeric information C Feedback: In the constructivist paradigm, it is assumed that reality is not a fixed entity but is rather a construction of human minds—and thus “truth” is a composite of multiple constructions of reality.

Constructivist researchers emphasize understanding human experience as it is lived through the collection and analysis of subjective, narrative materials using flexible procedures; this paradigm is associated with qualitative research. The other answers are truer of positivist, quantitative research. Quantitative and qualitative research share 11. which of the following features? Select all that apply. A desire to understand the true state of human affairs An emphasis on formal measurement A reliance on external evidence collected through the senses Utility to the nursing profession A, C, D Feedback: Both quantitative and qualitative research share a desire to understand the true state of human affairs, a reliance on external evidence collected through the senses, and utility to the nursing profession. However, quantitative, not qualitative, research emphasizes formal measurement. Which of the following is a descriptive 12. question that a qualitative researcher most likely would ask? What is the nature of this phenomenon? What is the average intensity of this phenomenon? How frequently does this phenomenon occur? What is the average duration of this phenomenon? A) B) C) D) Ans: A) B) C) D) Ans: A) B) C) D) Ans: Which of the following is a descriptive 12. question that a qualitative researcher most likely would ask? What is the nature of this phenomenon? What is the average intensity of this phenomenon? How frequently does this phenomenon occur? What is the average duration of this phenomenon? A Feedback: Description of phenomena is an important purpose of research. In descriptive studies, researchers count, delineate, and classify. Nurse researchers have described a wide variety of phenomena, such as patients' stress, health beliefs, and so on. Quantitative description focuses on the prevalence, size, and measurable aspects of phenomena. Qualitative researchers describe the nature, dimensions, and salience of phenomena A researcher wants to investigate the effect of 13. patients' body position on blood pressure. The study would most likely be of which type? Qualitative Quantitative Either quantitative or qualitative (researcher preference) Insufficient information to determine B Feedback: Because this study would involve a measurable, numeric outcome—blood pressure—it should most likely be a quantitative study. A researcher wants to explore the process by which men make decisions about treatment 14. for prostate cancer. The researcher's paradigm is most likely which of the following? Positivism Determinism Empiricism Constructivism D Feedback: As this study involves gathering subjective, non-measurable data, the researcher's paradigm is most likely constructivism.

Positivism Determinism Empiricism Constructivism D Feedback: As this study involves gathering subjective, non-measurable data, the researcher's paradigm is most likely constructivism. Positivism is not likely, as there is no emphasis on an objective, orderly reality. Determinism, which refers to the belief that phenomena result from prior causes and are not haphazard, is not pertinent here. Although the research will involve empiricism, or gathering information using the senses, this is not the primary paradigm. Which of the following would be most 15. strongly associated with cause-probing research? Identification Description Exploration Explanation D Feedback: A fundamental distinction that is especially relevant in quantitative research is between studies whose primary intent is to describe phenomena and those that are cause-probing. Specific purposes on the description/ explanation continuum include identification, description, exploration, prediction/control and explanation. Many nursing studies can also be classified in terms of a key EBP aim: therapy/treatment/intervention; diagnosis and assessment; prognosis; etiology and harm; and meaning and process. Nursing has experienced constant change over the past decades as a result of increased 16. research. When determining best practices, nursing decisions should do which of the following? Select all that apply. Be based on tradition Include holistic approaches Be clinically appropriate Be cost effective C, D Feedback: A) B) C) D) Ans: A) B) C) D) Ans: A) B) C) D) Ans: the past decades as a result of increased 16. research. When determining best practices, nursing decisions should do which of the following? Select all that apply. Be based on tradition Include holistic approaches Be clinically appropriate Be cost effective C, D Feedback: Nurse leaders recognize the need to base specific nursing decisions on evidence indicating that the decisions are clinically appropriate, cost-effective, and result in positive client outcomes. Holistic treatments may be appropriate in some, but not all, circumstances. Tradition alone is an inadequate basis for practice. Evidenced-based nursing primarily uses 17. which of the following to answer clinical questions? Consulting an authority Using intuition Obtaining the newest research Relying on experience C Feedback: Nurses are increasingly expected to understand and undertake research, and to base their practice on evidence from research —that is, to adopt an evidence-based practice (EBP). EBP, broadly defined, is the use of the best evidence in making patient care decisions. Experience, intuition, and authority are not wholly ignored in the EBP process, but research is a priority. The major difference between quantitative and qualitative research is that qualitative 18. research seeks to find answers based on which of the following? Solid factual data Experiences or descriptions Etiology Systematic process B Feedback: Human experiences, and people's descriptions and interpretations of these experiences, are the main focus of qualitative research. Systematic process, etiology, and factual data of the following? Solid factual data Experiences or descriptions Etiology Systematic process B Feedback: Human experiences, and people's descriptions and interpretations of these experiences, are the main focus of qualitative research. Systematic process, etiology, and factual data are more closely aligned with the quantitative tradition. A) B) C) D) Ans: 19. A) B) C) D) Ans: A) B) C) D) Ans: Which of the following research focuses is qualitative? Weekend and night outcomes of patients admitted to a specific hospital system's trauma departments Trends in hospitalizations of patients with antibiotic-resistant tuberculosis Predicting risks for serious complications with abdominal surgery Needs of nursing students living with chronic illness D Feedback: Constructivist studies are heavily focused on understanding the human experience as it is lived, through the careful collection and analysis of qualitative materials that are narrative and subjective. Human needs, and individuals' perceptions of those needs, are a common focus of qualitative research. Outcomes, risk factors, and treatment modalities are often addressed with quantitative research. When little is known about a phenomenon or the phenomenon is not clearly identified, the 20. best type of research suited to uncover this is which of the following? Exploration Description Identification Prediction C Feedback: Qualitative researchers sometimes study phenomena about which little is known. In some cases, so little is known that the phenomenon has yet to be clearly identified or A) B) C) D) Ans: Exploration Description Identification Prediction C Feedback: Qualitative researchers sometimes study phenomena about which little is known. In some cases, so little is known that the phenomenon has yet to be clearly identified or named or has been inadequately defined. Identification is thus necessary. Exploration (which addresses causation), predication, and description would likely be subsequent efforts. 21. A) B) C) D) Ans: 22. A) B) C) D) Ans: Consumers of research do which of the following? Design studies Undertake studies Produce research Read research D Feedback: In the current EBP environment, every nurse is likely to engage in one or more activity along a continuum of research participation. At one end of the continuum are users (consumers) of nursing research—nurses who read research reports to keep up-to-date on findings that may affect their practice. EBP depends on well-informed nursing research consumers. At the other end of the continuum are the producers of nursing research: nurses who actively design and undertake studies. When nurses rely primarily on tradition, they are most likely to do which of the following? Produce a precise range of answers Increase new knowledge Maintain an unbiased perspective Undermine effective problem solving D Feedback: Tradition may undermine effective problem solving. There is growing concern that many nursing actions are based on tradition, custom, and “unit culture” rather than on sound evidence. This prevents the acceptance of new knowledge and increases bias and is unlikely to produce a precise range of answers.

There is growing concern that many nursing actions are based on tradition, custom, and “unit culture” rather than on sound evidence. This prevents the acceptance of new knowledge and increases bias and is unlikely to produce a precise range of answers. A research nurse understands that evidenced23. based practice in nursing does which of the following? Relies on tradition Consults recognized authorities Depends primarily on textbooks Is based on the latest research D Feedback: EBP prioritizes research findings, which are found primarily in primary sources, such as journals, rather than in secondary sources, such as textbooks. It is not dependent on tradition or authority. 24. A) B) C) D) Ans: Non-research-based evidence includes which of the following? Select all that apply. Unit culture Nurse's experience Qualitative studies Trial and error C Feedback: Clinical reports, experience and beliefs are non-research based sources of evidence, which are considered to be comparatively weak. Qualitative studies are research-based. CHIA 's . 1. A) B) C) D) Ans: 2. A) B) C) D) Ans: Research utilization is a process that begins with which of the following? A clinical problem that needs to be solved A problem-focused trigger A knowledge-focused trigger or research finding A well-worded clinical question C Feedback: Research utilization (RU) is the use of findings from disciplined research in a practical application that is unrelated to the original research. Evidence-based practice is broader than RU because it integrates research findings with other factors. Several models of EBP, such as the Iowa Model, have distinguished two types of stimulus (“triggers”) for an EBP endeavor—(1) problem-focused triggers—the identification of a clinical practice problem in need of solution, or (2) knowledge-focused triggers— readings in the research literature. A second catalyst for an EBP project is the research literature—knowledge-focused triggers, which is the origin akin to research utilization. Which of the following is an example of a systematic review? An RCT study published in the journal Nursing Research A meta-analysis from the Cochrane database A synopsis published in Evidence-Based Nursing A clinical practice guideline from the National Guideline Clearinghouse B Feedback: A meta-analysis is a type of systematic review and a technique for integrating quantitative research findings statistically. In essence, meta-analysis treats the findings from a study as one piece of information. The findings from multiple studies on the same topic are combined and then all of the information is analyzed statistically in a manner similar to that in a usual study.

Unlike systematic reviews, clinical practice guidelines (which often are based on systematic reviews) give specific recommendations for evidence-based decision-making. Guideline development typically involves the consensus of a group of researchers, experts, and clinicians. A randomized controlled trial (RCT) is an individual study that focuses on the effectiveness of therapies rather than on broader health-care interventions. Synopses, or summaries, of systematic reviews and of single studies are available in evidence-based abstract journals such as Evidence-Based Nursing. D) Ans: 3. A) B) C) D) Ans: 4. A) B) C) D) Ans: Most evidence hierarchies put which of the following at the pinnacle? Randomized clinical trials (RCTs) Systematic reviews of multiple studies Quality improvement projects It depends on the research question B Feedback: In all evidence hierarchies that include randomized clinical trials, quality improvement projects and research questions, systematic reviews are at the pinnacle. Which of the following can be used to critically appraise clinical practice guidelines? A systematic review from the Cochrane Collaboration The Iowa model The AGREE instrument An evidence hierarchy C Feedback: Evidence-based clinical practice guidelines 4. A) B) C) D) Ans: A) B) C) D) Ans: Which of the following can be used to critically appraise clinical practice guidelines? A systematic review from the Cochrane Collaboration The Iowa model The AGREE instrument An evidence hierarchy C Feedback: Evidence-based clinical practice guidelines distill a body of evidence into a usable form. Unlike systematic reviews, clinical practice guidelines, which often are based on systematic reviews, give specific recommendations for evidence-based decision-making. Several appraisal instruments are available to evaluate clinical practice guidelines, but one with broad support is the Appraisal of Guidelines Research and Evaluation (AGREE) Instrument. The Iowa model is used in selecting a problem for an institutional evidence-based project. An evidence hierarchy is a tool for ranking evidence sources according to the strength of the evidence they provide. Which of the following models was explicitly 5. developed with the idea that individual nurses could engage in RU-type activities? Iowa Model Johns Hopkins Model Cochrane Model Stetler Model D Feedback: Some models focus on the use of research from the perspective of individual clinicians such as the Stetler Model, one of the oldest models that originated as an RU model, but most focus on institutional EBP efforts such as the John Hopkins Nursing EBP Model and the Iowa Model. There is no Cochrane Model; the Cochrane Collaboration is an organization that prepares, maintains, and promotes the accessibility of systematic reviews. A) B) C) D) Ans: A) B) C) D) Ans: A) B) C) D) Ans: In the following clinical question, what is the Outcome (O component): What is the effect 6. of relaxation therapy versus biofeedback on the functional ability of patients with rheumatoid arthritis? Functional ability Rheumatoid arthritis Biofeedback Relaxation therapy A Feedback: In the PIO acronym, P stands for the population or patients (rheumatoid arthritis); I stands for the intervention, influence, or exposure (biofeedback or relaxation therapy); and O stands for the outcomes (functional ability). In the following clinical question, what is the Intervention/influence/exposure (I 7. component): Does taking antidepressants affect the risk of suicide in cognitively impaired adolescents? Adolescence Suicide Antidepressant use Cognitive impairment C Feedback: In the PIO acronym, P stands for the population or patients (cognitively impaired individuals); I stands for the intervention, influence, or exposure (antidepressants); and O stands for the outcomes (risk of suicide).

Which of the following is a question that 11. would be asked as part of the process of appraising research evidence? What are the P, I, and O components? How rigorous and reliable is the evidence? What type of trigger should I use? Is a relevant systematic review available? B Feedback: Individual nurses have opportunities to put research into practice. The five basic steps for individual EBP are: (1) asking an answerable clinical question as evidenced by, “What are the P, I, and O components?” (2) searching for relevant research-based evidence as evidenced by, “Is a relevant systematic review available?” (3) appraising and synthesizing the evidence as evidenced by, “How rigorous and reliable is the evidence?” Triggers for an organizational project include both pressing clinical problems (problem-focused) and existing knowledge (knowledge-focused) such as asked by the question, “What type of trigger would I use?” Which of the following activities is part of an 12. organizational—but not an individual—EBP endeavor? Asking a good question/identifying a problem Searching for evidence Assessing implementation potential Synthesizing and appraising evidence C Feedback: EBP in an organizational context involves many of the same steps as individual EBP A) B) C) D) Ans: A) B) C) D) Ans: 12. organizational—but not an individual—EBP endeavor? Asking a good question/identifying a problem Searching for evidence Assessing implementation potential Synthesizing and appraising evidence C Feedback: EBP in an organizational context involves many of the same steps as individual EBP efforts, but is more formalized and must take organizational factors into account. Triggers for an organizational project include both pressing clinical problems (problem-focused) and existing knowledge (knowledge-focused), such as assessing implementation potential. Individual nurses have opportunities to put research into practice. The five basic steps for individual EBP are: (1) asking an answerable clinical question; (2) searching for relevant research-based evidence; (3) appraising and synthesizing the evidence; (4) Integrating the evidence with your own clinical expertise, patient preferences, and local context; (5) Assessing the effectiveness of the decision, intervention, or advice. Asking a clinical question is the first step in 13. evidence-based practice. What are the four components of a PICO clinical question? Population, implication, comparison, outcome Population, intervention, clinical, outcome Population, intervention, comparison, outcome Population, implication, clinical, outcome C Feedback: A crucial first step in evidence-based practice (EBP) involves asking relevant clinical questions that reflect uncertainties in clinical practice. Most guidelines for EBP use the acronyms PIO or PICO to help practitioners develop well-worded questions that facilitate a search for evidence. In the acronym PIO, the P stands for population or patients; the I stands for intervention; and the O stands for outcome. The acronym PICO includes these same three components plus a fourth, C, which stands for comparison.

A) B) C) D) Ans: A) B) C) D) Ans: Which following level of evidence includes systematic reviews of multiple studies? Level IV Level III Level II Level I D Feedback: Systematic reviews are at the pinnacle of the hierarchy (Level I), because the strongest evidence comes from careful syntheses of multiple studies. The next highest level (Level II) includes individual randomized controlled trials (RCTs). Going down the “rungs” of the evidence hierarchy for Therapy questions results in less reliable evidence—for example, Level III evidence comes from a type of study called quasi-experiment. In-depth qualitative studies are near the bottom, in terms of evidence regarding intervention effectiveness. A nurse in the United States is scheduled to care for a child with an ostomy.

MEDLINE TRIP www.guidelines.gov www.rnao.org/bestpractices C Feedback: Finding clinical practice guidelines can be challenging, because there is no single guideline repository. A standard search in bibliographic databases such as MEDLINE will yield many references—but could yield a mixture of citations to not only the actual guidelines, but also to commentaries, implementation studies, and so on. A recommended approach is to search in guideline databases, or through specialty organizations that have sponsored guideline development. In the United States, nursing and health-care guidelines are maintained by the National Guideline Clearinghouse (www.guideline.gov). In Canada, the Registered Nurses Association of Ontario (RNAO) (www.rnao.org/bestpractices) maintains information about clinical practice guidelines. Two sources in the United Kingdom are the Translating Research into Practice (TRIP) database and the National Institute for Clinical Excellence (NICE). Which of following study types is a 16. systematic review used for integration of statistical quantitative research findings? Meta-synthesis Meta-analysis Randomized controlled trial Quasi-experiment B Feedback: Systematic reviews can take various forms. One form is a narrative (qualitative) integration that merges and synthesizes findings, much like a rigorous literature review. For integrating evidence from quantitative studies, narrative reviews increasingly are being replaced by a type of systematic review known as a meta-analysis.

The best-known early research utilization (RU) project sought to bridge the gap between 17. research and practice. Which following is the name of that well-known project? Cochrane Collaboration Stetler Model of Research Utilization Conduct and Utilization of Research in Nursing (CURN) Project Promoting Action on Research Implementation in Health Services C Feedback: Recognition of the gap between research and practice led to formal attempts to bridge the gap. The best-known of several early RU projects is the Conduct and Utilization of Research in Nursing (CURN) Project, which was awarded to the Michigan Nurses' Association by the Division of Nursing in the 1970s. The Stetler Model of Research Utilization and Promoting Action on Research Implementation in Health Services are evidence-based practice models, not projects. One keystone of the EBP movement is the Cochrane Collaboration, which was founded in the United Kingdom based on work by British epidemiologist Archie Cochrane. It is not a research utilization project.

Which of the following is a problem-focused trigger in the Iowa Model? A finding published recently in a nursing journal A new clinical guideline issued by a federal agency An increase in latex allergy among emergency room nurses Questions from hospital committee C Feedback: Several models of EBP, such as the Iowa Model, have distinguished two types of stimulus (“triggers”) for an EBP endeavor— (1) problem-focused triggers—the identification of a clinical practice problem in need of solution, or (2) knowledge-focused triggers—readings in the research literature. A second catalyst for an EBP project is the research literature—knowledge-focused triggers, which is the origin akin to research utilization. The catalyst might be a new clinical guideline or a research article discussed in a journal club. A) B) C) D) Ans: As a nurse, you must understand the difference between research utilization and 19. evidence-based nursing practice. Which of the following best defines evidence-based practice? Begins with research itself, clinical expertise, and patient preference Uses new evidence and translates research findings into real-world applications Uses findings from disciplined research in practical application unrelated to original research Integrates best research evidence, with clinical expertise, patient preference, and a particular clinical situation D Feedback: Advocates of EBP do not minimize the importance of clinical expertise. Rather, they argue that evidence-based decision-making should integrate best research evidence with clinical expertise, patient preferences, and local circumstances. Research utilization (RU) is the use of findings from disciplined research in a practical application that is unrelated to the original research. In research utilization, the emphasis is on translating research findings into real-world applications. The starting point in RU is new evidence or a research-based innovation. EBP is broader than RU because it integrates research findings with other factors. Whereas RU begins with the research itself (how can I put this innovation to good use in my clinical setting?), EBP starts with a clinical question (what does the evidence say is the best approach to solving this problem?). A) B) C) D) Ans: A) B) C) D) Ans: Some EBP models recommend a formal assessment of organizational “fit,” known as implementation potential, when an organization is considering undertaking an 20. EBP project. Which following issue is of particular importance to address to determine the implementation potential of the EBP project for the organization? Effectiveness of the innovation Nurses' attitude toward the innovation Patient benefit of the innovation Transferability of the innovation D Feedback: Some EBP models recommend a formal assessment of organizational “fit,” often called implementation potential (or, environmental readiness). In determining the implementation potential of an innovation in a particular setting, several issues should be considered, particularly the transferability of the innovation (i.e., the extent to which the innovation might be appropriate in new settings), the feasibility of implementing it, and its cost-benefit ratio. A nurse is observing how the time of feeding impacts an inpatient's gastric reflux. In which of the following steps of the EBP process 21. would the nurse determine whether a specific feeding time alleviated the patient's gastric reflux symptoms? Searching for and collecting evidence that addresses the question Appraising and synthesizing the evidence Integrating the evidence with own clinical expertise, patient preferences, and local context Assessing the effectiveness of the decision, intervention, or advice D Feedback: It would be during step 5 of the EBP process, assessing the effectiveness of the decision, intervention, or advice, that the nurse would determine whether a specific feeding time (an intervention) is effective in alleviating the patient's gastric reflux symptoms. D) Ans: A) B) C) D) Ans: A) B) C) D) Ans: context Assessing the effectiveness of the decision, intervention, or advice D Feedback: It would be during step 5 of the EBP process, assessing the effectiveness of the decision, intervention, or advice, that the nurse would determine whether a specific feeding time (an intervention) is effective in alleviating the patient's gastric reflux symptoms. After an institutional project has been developed, the next step is to conduct a pilot 22. study (a trial study). Based on the Iowa Model, which step would identify the success or failure of a pilot study? Developing an evaluation plan Measuring client outcomes prior to implementation Training relevant staff in the use of the new guideline Evaluating the project in terms of both the process and the outcomes D Feedback: The success or failure of the pilot study would be assessed in the evaluation of the study, which is the last step. The other answers refer to earlier steps in the implementation of the study. A narrative integrated review of qualitative studies focuses on interpretation of the 23. studies. Which of the following study types would be considered an systematic integrated review of qualitative studies? Meta-synthesis Meta-analysis Randomized controlled trial Quasi-experiment A Feedback: Systematic reviews can take various forms. One form is a narrative (qualitative) integration that merges and synthesizes findings, much like a rigorous literature review. For integrating evidence from quantitative studies, narrative reviews increasingly are being replaced by a type of systematic review known as a meta-analysis.

One form is a narrative (qualitative) integration that merges and synthesizes findings, much like a rigorous literature review. For integrating evidence from quantitative studies, narrative reviews increasingly are being replaced by a type of systematic review known as a meta-analysis. Meta-analysis is a technique for integrating quantitative research findings statistically. For qualitative studies, integration may take the form of a meta-synthesis. A meta-synthesis, however, is distinct from a quantitative metaanalysis: a meta-synthesis is less about reducing information and more about interpreting it. Randomized controlled trials and quasi-experiments are not types of systematic reviews. The Iowa Model identifies several knowledge-focused triggers for implementing 24. an EBP project. Which following statement is considered a knowledge-focused trigger in the Iowa Model? A report in the New England Journal of Medicine regarding a potential flu epidemic Readmission rate of heart failure patients Poor patient survey results Increase in pediatric falls A Feedback: Several models of EBP, such as the Iowa Model, have distinguished two types of stimulus (“triggers”) for an EBP endeavor— (1) problem-focused triggers—the identification of a clinical practice problem in need of solution, or (2) knowledge-focused triggers—readings in the research literature. A report in a medical journal regarding a potential flu epidemic is an example of a reading in a research literature, and thus would be a knowledge-focused trigger. The other answers are examples of problemfocused triggers.

Polit and Beck is the textbook you are using, which is a secondary source, not primary research. CHI CH 3 A) B) C) D) Ans: A) B) C) D) Ans: Which of the following terms would likely be used only by qualitative researchers, as 1. opposed to quantitative researchers, to refer to people who participate in a study? Informants Study participants Subjects Investigators A Feedback: The people who provide information to the researchers in a study are referred to as subjects or study participants in quantitative research, or study participants or informants in qualitative research; collectively they comprise the sample. The person who conducts the research is the researcher or investigator. Which of the following terms is used by both 2. qualitative and quantitative researchers to refer to the abstractions under study? Concept Theory Phenomenon Variable A Feedback: Researchers investigate concepts and phenomena, which are abstractions inferred from people's behavior or characteristics. In quantitative studies, concepts are called variables. A variable is a characteristic or quality that takes on different values. The term phenomena is also more associated with qualitative studies than with quantitative studies, whereas concept is used for both. A theory is an explanation of some aspect of reality, not an abstraction inferred from people's behavior or characteristics. 3. A) B) C) D) Ans: A) B) C) D) Ans: Which of the following would be most likely called a construct? Gender Body temperature Self-care Blood type C Feedback: Researchers sometimes use the term construct, which also refers to an abstraction, but often one that is deliberately invented (or constructed). For example, self-care in Orem's model of health maintenance is a construct. A variable is a characteristic or quality that takes on different values such as body temperature and blood type. Gender can be coded in a quantitative study. 4. "Male" is which of the following? Not a variable An independent variable A dependent variable An outcome variable A Feedback: A variable is a characteristic or quality that takes on different values (i.e., varies from one person or object to another). The dependent (or outcome) variable is the behavior, characteristic, or outcome the researcher is interested in explaining, predicting, or affecting (the “O” in the PICO scheme). The independent variable is the presumed cause of or influence on the dependent variable. The independent variable corresponds to the “I” and the “C” components in the PICO scheme. Thus, “male” is not a variable, but a constant. A) B) C) D) Ans: A) B) C) D) Ans: The dependent (outcome) variable in the research question, "Is the quality of life of 5. nursing home residents affected by their functional ability or hearing acuity?” is which of the following? Quality of life Functional ability Hearing acuity Residence in a nursing home A Feedback: The dependent (or outcome) variable is the behavior, characteristic, or outcome the researcher is interested in explaining, predicting, or affecting (the “O” in the PICO scheme). Quality of life is the dependent variable. The independent variable is the presumed cause of or influence on the dependent variable. Independent variables are nursing home residents, functional ability, and hearing acuity. The independent variable corresponds to the “I” and the “C” components in the PICO scheme. The independent variable in the research question, "What is the effect of noise levels 6. on postoperative pain and blood pressure fluctuations in ICU patients?" is which of the following? Blood pressure ICU patients Noise levels Postoperative pain C Feedback: The dependent (or outcome) variable is the behavior, characteristic, or outcome the researcher is interested in explaining, predicting, or affecting (the “O” in the PICO scheme). Postoperative pain, blood pressure, and being a patient in the ICU are the dependent variables. The independent variable is the presumed cause of or influence on the dependent variables. The independent variable is noise levels. The independent variable corresponds to the “I” and the “C” components in the PICO scheme. B) C) D) Ans: A) B) C) D) Ans: A) B) C) D) ICU patients Noise levels Postoperative pain C Feedback: The dependent (or outcome) variable is the behavior, characteristic, or outcome the researcher is interested in explaining, predicting, or affecting (the “O” in the PICO scheme).

The independent variable is noise levels. The independent variable corresponds to the “I” and the “C” components in the PICO scheme. In the question, "Do Baccalaureate degree– prepared nurses practice more rehabilitative nursing procedures on a client in an ICU than 7. associate degree–prepared nurses?" the independent variable is which of the following? Associate degree–prepared nurses Baccalaureate degree–prepared nurses Rehabilitative nursing measures Type of educational background of nurse D Feedback: The dependent (or outcome) variable is the behavior, characteristic, or outcome the researcher is interested in explaining, predicting, or affecting (the “O” in the PICO scheme). A rehabilitative nursing measure is the dependent variable. The independent variable is the presumed cause of or influence on the dependent variable. The independent variable is type of educational background of nursing, not a particular degree. The independent variable corresponds to the “I” and the “C” components in the PICO scheme. The purpose of an operational definition in a 8. quantitative study is to do which of the following? Assign numeric values to variables Specify how a variable will be measured State the expected relationship between the variables under investigation Designate the conceptual underpinnings of the variable A) B) C) D) Ans: A) B) C) D) Ans: A) B) C) D) The purpose of an operational definition in a 8. quantitative study is to do which of the following? Assign numeric values to variables Specify how a variable will be measured State the expected relationship between the variables under investigation Designate the conceptual underpinnings of the variable B Feedback: A conceptual definition describes the abstract or theoretical meaning of a concept being studied. An operational definition specifies how the variable will be measured. Data—the information collected during the course of a study—may take the form of narrative information (qualitative data) or numeric values (quantitative data). Which of the following is a datum from a 9. quantitative study of the labor and delivery experiences of women over age 40? Length of time in labor 107 oz “I practically slept through the whole thing!” Vaginal versus cesarean delivery B Feedback: Research data (singular, datum) are the pieces of information gathered in a study. In quantitative studies, researchers identify and define their variables, and then collect relevant data from subjects. The actual values of the study variables constitute the data. Quantitative researchers collect primarily quantitative data—information in numeric form. In this question it is 107 oz. Length of time in labor, “I practically slept through the whole thing,” and vaginal versus cesarean delivery are not documented as numeric values in this example. Which of the following is a datum from a 10. qualitative research study on the labor and delivery experiences of women over age 40? 14.6 hours in labor 60-minute interviews one day after delivery "It was a nightmare—much more painful than I ever imagined." 15 women with a vaginal delivery A) B) C) D) Ans: Which of the following is a datum from a 10. qualitative research study on the labor and delivery experiences of women over age 40? 14.6 hours in labor 60-minute interviews one day after delivery "It was a nightmare—much more painful than I ever imagined." 15 women with a vaginal delivery C Feedback: Quantitative researchers collect primarily quantitative data—information in numeric form. 14.6 hours in labor, 60 minute interviews one day after delivery, and 15 women with a vaginal delivery are examples of quantitative data. In qualitative studies, researchers collect primarily qualitative data, that is, narrative descriptions. Narrative data can be obtained by conversing with participants, by making notes about their behavior in naturalistic settings, or by obtaining narrative records, such as diaries. “It was a nightmare – much more painful than I ever imagined,” is an example of datum from a qualitative research study. 11. A) B) C) D) Ans: In quantitative studies, the most basic distinction is between which of the following? Grounded theory and phenomenological research Empirical and nonempirical research Experimental and nonexperimental research Population-based and sample-based research C Feedback: A key distinction in quantitative studies is between experimental research, in which researchers actively intervene to test an intervention or therapy, and nonexperimental (or observational) research, in which researchers make observations of existing phenomena without intervening. Grounded theory seeks to describe and understand key social psychological processes that occur in a social setting. Phenomenology focuses on the lived experiences of humans and is an approach to gaining insight into what the life experiences of people are like and what they mean. In quantitative research, the empirical phase involves collecting data; and preparing data for analysis (e.g., coding data).

Experimental Phenomenologic Ethnographic Grounded theory A Feedback: Qualitative research often is rooted in research traditions that originate in other disciplines. Three such traditions are grounded theory, phenomenology, and ethnography. Grounded theory seeks to describe and understand key social psychological processes that occur in a social setting. Phenomenology focuses on the lived experiences of humans and is an approach to gaining insight into what the life experiences of people are like and what they mean.

A researcher's expectations about the relationships between variables in a 15. quantitative study are generally formulated as which of the following? Hypotheses Frameworks Research questions Conceptual definitions A Feedback: Hypotheses state researchers' deductively derived expectations about relationships between study variables. To answer research questions and test hypotheses, researchers analyze their data in an orderly fashion. When quantitative research is performed within the context of a theoretical framework, the findings may have broader significance and utility. Even when the research question is not embedded in a theory, researchers should have a conceptual definition rationale and a clear vision of the concepts under study.

The overall plan for answering a research 16. question—the architectural backbone of a study—is called which of the following? Sampling plan Proposal Hypothesis Research design D Feedback: The research design is the overall plan for obtaining answers to the research questions and for handling challenges that can undermine the study evidence. The researcher's sampling plan specifies how the sample will be selected and how many subjects there will be. Researchers seeking financial support submit a proposal to a funding source, and reviewers usually suggest improvements. Hypotheses state researchers' deductively derived expectations about relationships between study variables. The aggregate of those to whom a researcher 17. wishes to generalize study results is which of the following? Gatekeepers Population Sample Sampling plan B Feedback: A population is all the individuals or objects with common, defining characteristics (the “P” component in PICO questions). Gaining the following? Gatekeepers Population Sample Sampling plan B Feedback: A population is all the individuals or objects with common, defining characteristics (the “P” component in PICO questions). Gaining entrée to a research site for a particular population typically involves negotiations with gatekeepers who have the authority to permit entry into their world. Researchers typically collect data from a sample, which is a subset of the population. Using samples is more practical than collecting data from an entire population, but the risk is that the sample might not adequately reflect the population's traits. The researcher's sampling plan specifies how the sample will be selected and how many subjects there will be.

There is no interpretive research design in qualitative studies. At what point does a qualitative researcher 20. typically make a lot of decisions about data collection and sampling? While reviewing the literature During the development of a research report While the study is in progress in the field After developing an intervention protocol C Feedback: In qualitative studies, the tasks of sampling, data collection, data analysis, and interpretation typically take place repeatedly while the study is in progress. Qualitative researchers begin by talking with or observing people with first-hand experience with the phenomenon under study. The discussions and observations are loosely structured, allowing participants to express a full range of beliefs, feelings, and behaviors. Analysis and interpretation are ongoing, concurrent activities that guide choices about the kinds of people to question next and the types of question to ask or observations to make. Reviewing the literature, developing a research report, and developing an intervention protocol are steps in quantitative research.

The dependent variable in the research question, “Is the quality of life of nursing 23. home residents affected by their functional ability or hearing acuity?” is which of the following? Quality of life Functional ability Hearing acuity Residence in a nursing home A Feedback: The presumed cause is the independent variable and the presumed effect is the dependent or outcome variable. Variation in the dependent variable is presumed to depend on variation in the independent variable. In this case, the presumed causes are functional ability or hearing acuity. The presumed effect is quality of life, which is thus the dependent variable. Residence in a nursing home is not the effect.

The purpose of an operational definition in a 25. quantitative study is to do which of the following? Assign numeric values to variables Specify how a variable will be measured State the expected relationship between the variables under investigation Designate the conceptual underpinnings of a variable B Feedback: An operational definition indicates what the researchers specifically must do to measure the concept and collect needed information. The operational definition does not assign numeric values to variables, state the expected relationship between the variable under investigation, or designate the conceptual underpinnings of a variable. A researcher conceptualizes pain as “the subject's statement of intensity of pain.” What 26. operational definition is consistent with this conceptualization? Measurement of subject's pulse and blood pressure Nurse's observation of subject's pain behavior Subject's score on self-reported pain rating scale Frequency of subject's use of pain medication C Feedback: An operational definition indicates what the researchers specifically must do to measure the concept and collect needed information.

Study situations to aid in theory development Describe experiences as they are lived Observe and document interactions within a culture Examine events of the past C Feedback: Ethnography provides a framework for studying the meanings, patterns, and lifeways of a culture in a holistic fashion. It does not study situations to aid in theory development, nor describe experiences as they are lived (phenomenology). It does not examine events of the past. In qualitative research, saturation indicates which of the following? There are too many subjects Themes in the data are repeating Too many variables are included in a study The quality of the data is excellent B Feedback: Many qualitative researchers use the principle of saturation, which occurs when themes and categories in the data become repetitive and redundant, such that no new information can be gleaned by further data collection. Saturation does not indicate that there are too many subjects or too many variables or that the quality of the data is excellent.

Select all that apply. Poster sessions Journal articles Textbooks Dissertations A, B Feedback: Nurses are most likely to encounter research evidence in journals or at professional conferences. Research journal articles are descriptions of studies published in professional journals. At conferences, research findings are presented as oral presentations or poster sessions. A textbook is not a primary source for research results, but rather an overview of established knowledge in a field. Dissertation is defense of research that has been conducted. When a research report undergoes a “blind” 2. review for a journal, it means which of the following? The journal editors do not know who submitted the report. The authors of the report do not know who the editor of the journal is. The report is published without indicating the authors' names. The reviewers making recommendations about publication are not told who the authors are. D Feedback: Usually, manuscripts are reviewed by two or more peer reviewers (other researchers) who make recommendations about whether to accept or reject the manuscript, or to suggest revisions. Reviews are usually “blind”— reviewers are not told researchers' names, and authors are not told reviewers' names. As a result of peer review, consumers have some assurance that journal articles have been critiqued by other nurse researchers.

Reliability Validity Credibility Generalizability B Feedback: Validity is a more complex concept that broadly concerns the soundness of the study's evidence—that is, whether the findings are cogent, convincing, and well grounded. Reliability (a key challenge in quantitative research) refers to the accuracy and consistency of information obtained in a study. Credibility is achieved to the extent that the methods engender confidence in the truth of the data and in the researchers' interpretations. Generalizability in a quantitative study concerns the extent to which the findings can be applied to other groups and settings. Which of the following is an aspect of 11. trustworthiness used in evaluating the strength of evidence in a qualitative study? Triangulation Reflexivity Reliability Credibility D Feedback: Credibility is achieved to the extent that the methods engender confidence in the truth of the data and in the researchers' interpretations. Triangulation, the use of multiple sources or referents to draw conclusions about what constitutes the truth, is one approach to enhancing credibility. Reliability (a key challenge in quantitative research) refers to the accuracy and consistency of information obtained in a study. Reflexivity, the process of reflecting critically on the self and of scrutinizing personal values that could affect data collection and interpretation, is an important tool in qualitative research.

A nurse researcher compared men's and women's level of stress following cardiac surgery and made sure that both groups were 12. comparable with regard to length of stay in hospital. Length of stay in hospital is which of the following? Independent variable Dependent variable Mediating variable Confounding variable D Feedback: Researchers seek to control confounding (or extraneous) variables—variables that are extraneous to the purpose of a specific study but that might contaminate the results because they may be the actual cause or influence on the dependent variable. In this case, length of stay in the hospital may be the actual cause or at least one cause of the level of stress, instead of the cardiac surgery. The dependent variable is the behavior, characteristic, or outcome the researcher is interested in explaining, predicting, or affecting, which in this case is level of stress. The independent variable is the presumed cause of or influence on the dependent variable, which is cardiac surgery, in this case. The independent variable corresponds to the “I” and the “C” components in the PICO scheme. A mediating variable is a factor through which another factor has an effect on a dependent variable.

Bias Statistical test Research control Triangulation D Feedback: Triangulation is the use of multiple sources or referents to draw conclusions about what constitutes the truth. A bias is an influence that results in an error in an inference or estimate. Researchers use statistical tests to test their hypotheses and assess the probability that the results are accurate. Research control usually involves holding constant influences on the outcome variable so that the true relationship between the independent and outcome variables can be understood. CHS A) B) C) D) Ans: A) B) C) D) Ans: Based on what we know from this chapter, the 1. Tuskegee Syphilis Study violated which of the following? Select all that apply. Freedom from harm Right to self-determination Right to fair treatment Privacy rule A, B, C Feedback: The Tuskegee Syphilis Study, sponsored by the U.S. Public Health Service, investigated the effects of syphilis among 400 poor African-American men. Medical treatment was deliberately withheld to study the course of the untreated disease and violated the ethical principles of freedom from harm, right to self-determination, and the right to fair treatment. The Privacy Rule refers to the Health Insurance Portability and Accountability Act of 1996, which articulates federal standards to protect patients' medical records and health information. The regulations affecting the ethical conduct of research sponsored by the U.S. federal 2. government were based on which of the following? Nuremberg Code Declaration of Helsinki Belmont Report Code of Ethics of the American Nurses Association C Feedback: In the United States, an important code of ethics was adopted by the National Commission for the Protection of Human Subjects of Biomedical and Behavioral Research. The commission issued a report in 1978, known as the Belmont Report, which provided a model for many guidelines adopted by disciplinary organizations in the United States. The Belmont Report also served as the basis for regulations affecting research sponsored by the U.S. government. The Nuremberg Code was developed in response to the Nazi atrocities.

Which of the following are potential benefits 4. from participating in a study? Select all that apply. Monetary gains Access to a new and potentially beneficial treatment Opportunity to discuss personal feelings and experiences with an objective listener Opportunity to help determine the research question that the study is based on A, B, C Feedback: One strategy that researchers use to protect participants is to conduct a risk/benefit assessment. Such an assessment is designed to evaluate whether the benefits of participating in a study are in line with the costs, be they financial, physical, emotional, or social—i.e., whether the risk/benefit ratio is acceptable. Major potential benefits to participants include access to a potentially beneficial intervention, opportunity to discuss a problem with an objective person, increased knowledge about self or conditions, escape from normal routine, satisfaction in helping others by information gained through study, and direct monetary or material gains. Study participants are not given the opportunity to help determine the research question for the study; that is done by the researchers.

Which of the following comprise the three 5. primary ethical principles articulated by the Belmont Report? Select all that apply. Beneficence Respect for human dignity Anonymity Justice A, B, D Feedback: The Belmont Report articulated three primary ethical principles on which standards of ethical research conduct are based: beneficence, respect for human dignity, and justice. Anonymity is a method used by researchers to protect study participants' confidentiality by not linking the participants to their data. If a researcher unobtrusively studies 6. interactions among patients in a psychiatric hospital, what might this be called? Research misconduct Breach of confidentiality Covert data collection Deception C Feedback: Covert data collection or concealment is A) B) C) D) Ans: A) B) C) D) Ans: If a researcher unobtrusively studies 6. interactions among patients in a psychiatric hospital, what might this be called? Research misconduct Breach of confidentiality Covert data collection Deception C Feedback: Covert data collection or concealment is collecting data without participants' knowledge and thus without their consent. This might happen if a researcher wanted to observe people's behavior and was concerned that doing so openly would change the behavior of interest. Ethical conduct in research involves not only protecting the rights of human and animal subjects, but also efforts to maintain high standards of integrity and avoid such forms of research misconduct as plagiarism, fabrication of results, or falsification of data. Another challenge that many qualitative researchers face is adequately disguising participants in their reports to avoid a breach of confidentiality. Deception can involve deliberately withholding information about the study, or providing participants with false information. The safeguard mechanism by which even the researcher cannot link the participant with the 7. information provided is called which of the following? Confidentiality Anonymity Informed consent Right to privacy B Feedback: Privacy can be maintained through anonymity (wherein not even researchers know participants' identities) or through formal confidentiality procedures that safeguard the information participants provide. Informed consent procedures provide prospective participants with information needed to make a reasoned decision about participation. Right to privacy is protected through confidentiality procedures. B) C) D) Ans: A) B) C) D) Ans: Anonymity Informed consent Right to privacy B Feedback: Privacy can be maintained through anonymity (wherein not even researchers know participants' identities) or through formal confidentiality procedures that safeguard the information participants provide. Informed consent procedures provide prospective participants with information needed to make a reasoned decision about participation. Right to privacy is protected through confidentiality procedures. Confidentiality of study participants can be 8. most effectively protected by which of the following? Avoiding the collection of any identifying information Performing a risk/benefit assessment Placing all identifying information on computer files rather than manual files Obtaining informed consent from participants before the study A Feedback: Study participants have the right to expect that any data they provide will be kept in strict confidence, and this right is most effectively protected by avoiding the collection of any identifying information. Placing identifying information in a computer file rather than in a manual file does not help protect patients' confidentiality, and may in fact increase the risk for a breach of confidentiality. Performing a risk/benefit assessment helps researchers minimize the risk that participants are exposed to, and obtaining informed consent ensures that participants are fully informed of the nature of the study and can make an informed decision as to whether to participate. Neither of these addresses confidentiality, however. 9. A) B) C) D) Ans: 10. A) B) C) D) Ans: Vulnerable study participants would include which of the following? Women hospitalized for a mastectomy Members of a senior citizens group People who do not speak English Pediatric patients D Feedback: Vulnerable populations may be incapable of giving fully informed consent (e.g., pediatric patients, developmentally delayed people, mentally/emotionally disabled people, severely ill or physically disabled people) or may be at high risk of unintended side effects (e.g., pregnant women). Vulnerable populations do not include women hospitalized for a mastectomy, members of a senior citizens group or people who do not speak English. In what situation is informed consent not needed? The researcher pays the participants a stipend The risk/benefit ratio is low A Certificate of Confidentiality has been obtained Informed consent is always needed D Feedback: Informed consent procedures, which provide prospective participants with information needed to make a reasoned decision about participation, normally involve signing a consent form to document voluntary and informed participation. Informed consent is needed even when the researcher pays the participants a stipend or the risk/benefit ratio is low. A Certificate of Confidentiality is a legal document that researchers may obtain that protects them against the forced disclosure of confidential information in any civil, criminal, administrative, or legislative proceeding. However, it does not negate the need to obtain informed consent from participants of studies.

A Certificate of Confidentiality is a legal document that researchers may obtain that protects them against the forced disclosure of confidential information in any civil, criminal, administrative, or legislative proceeding. However, it does not negate the need to obtain informed consent from participants of studies. In a qualitative study that involves multiple contacts between the researcher and study 11. participants, the researcher may negotiate which of the following? Implied consent Stipend Process consent Risk/benefit ratio C Feedback: In qualitative studies, consent may need to be continually renegotiated with participants as the study evolves, through process consent procedures. Researchers often assume implied consent by the return of a completed questionnaire, which reflects the person's voluntary consent to participate. A major potential benefit to participants is direct monetary or material gains through stipends or other incentives; however, these are not typically negotiated during the study but are determined at the beginning of the study. In a risk/benefit assessment, the potential benefits of the study to individual participants and to society are weighed against the costs to individuals. 12.

Grandmother with legal guardianship Parent Sibling over 18 years of age Child over 7 years old A, B Feedback: Children are an identified vulnerable group and do not have the competence to give informed consent. Consent must be obtained from a parent or legal guardian. However, it is appropriate—especially if the child is at least 7 years of age—to obtain the child's assent, as well. 14. A) B) C) D) Ans: Which of the following is an example of research misconduct? Fabrication of data Concealed observation IRB rejection A high monetary incentive to study participants A Feedback: Ethical conduct in research involves not only protecting the rights of human and animal subjects but also efforts to maintain high standards of integrity and avoid such forms of research misconduct as plagiarism, fabrication of results, or falsification of data. Concealed observation, IRB rejection, or a high monetary incentive to study participants does not constitute research misconduct. Vulnerable groups include which of the following?

A) B) C) D) Ans: Vulnerable groups include which of the following? Select all that apply. Prisoners Pregnant women Young adults between 19 and 24 years of age Infants and toddlers A, B, D Feedback: Vulnerable populations need extra protections, and prisoners, pregnant women, and children are considered vulnerable populations. Young adults are not considered a vulnerable population. In a qualitative study, process consent is used for which of the following reasons? The researcher may need to renegotiate consent to gather more data. The researcher needs consent for each of the surveys to be answered. The participant may divulge private information and then regret it. The participant may forget the risks involved in a study after being initially informed. A Feedback: In some qualitative studies, the researcher adjusts the data collection as the data is collected and thus the need to obtain informed consent may change. The other answers are not valid reasons for using process consent. Which of the following best describes an assent form? The assent form allows a child to agree to be part of a research study. The assent form is read by the researcher for those who do not speak or read English. The assent form protects study participants from discrimination due to cultural diversity. The assent form allows the child over 7 years of age to give informed consent to participate in a study. A Feedback: Children can give assent—or affirmative agreement to be in a study—but cannot give informed consent because they are a vulnerable population. C) from discrimination due to cultural diversity. The assent form allows the child over 7 years of age to give informed consent to participate in a study.

Keeping painful procedure information from the study participant until the study is completed. Preventing psychological discomfort during and after the study. Proposing a study that ultimately benefits society despite the risk to the participants. A Feedback: The researcher considers risks and the benefits of the study for the client in order to protect the participants. Informed consent means that participants have adequate information about the study, comprehend the information, and have the power of free choice, enabling them to consent to or decline participation voluntarily. Keeping painful procedure information from the study participant would violate informed consent and should not be done. The nurse is not always able to prevent psychological discomfort during and after the study. Simply because a study may ultimately benefit society, it does not necessarily follow that this benefit will outweigh the risks to participants. Which of the following statements is true of confidentiality and anonymity? Confidentiality is implemented when a researcher cannot guarantee anonymity. Confidentiality of participant information may occur during a research study whereas anonymity is required. Confidentiality is a sign of respect for the participant by the researcher but anonymity is a legal issue. 18. A) B) C) D) Ans: A) B) C) D) Ans: Which of the following statements is true of confidentiality and anonymity? Confidentiality is implemented when a researcher cannot guarantee anonymity. Confidentiality of participant information may occur during a research study whereas anonymity is required. Confidentiality is a sign of respect for the participant by the researcher but anonymity is a legal issue. Confidentiality procedures require a researcher to disclose illegal behavior whereas anonymity protects the researcher from disclosing a participant's illegal behavior. A Feedback: Anonymity, the most secure means of protecting confidentiality, occurs when the researcher cannot link participants to their data. When anonymity is impossible, appropriate confidentiality procedures need to be implemented. A promise of confidentiality is a pledge that any information participants provide will not be publicly reported in a manner that identifies them and will not be made accessible to others. In a legal case, a participant is protected if a 19. Certificate of Confidentiality was issued by which of the following? The National Institutes of Health to prevent forced disclosure The Internal Review Board of the institution to protect the participant The principle researcher to avoid a breach of confidentiality The court to protect a member of a vulnerable group A Feedback: To avoid the risk of forced disclosure of sensitive information (e.g., through a court order), researchers in the United States can apply for a Certificate of Confidentiality from the National Institutes of Health (NIH). The certificate allows researchers to refuse to disclose information on study participants in any civil, criminal, administrative, or legislative proceeding. C) D) Ans: A) B) C) D) Ans: A) B) C) D) Ans: confidentiality The court to protect a member of a vulnerable group A Feedback: To avoid the risk of forced disclosure of sensitive information (e.g., through a court order), researchers in the United States can apply for a Certificate of Confidentiality from the National Institutes of Health (NIH). The certificate allows researchers to refuse to disclose information on study participants in any civil, criminal, administrative, or legislative proceeding. In both qualitative and quantitative studies, 20. researchers use debriefing to do which of the following? Allow participants to ask questions and give feedback to the researcher Allow the researcher to assess the participant before they leave the study site Explain to the participant what information they can tell others Describe the purpose of the study and the consent form A Feedback: Debriefing is used by researchers at the end of the study session to answer participants' questions and concerns about the study, especially if the study creates stress in the participants. Which of the following is an ethical principle 21. cited by the Belmont Report as a standard for research? Beneficence Philanthropy Duty Morality A Feedback: Beneficence is the only choice which is a principle of the Belmont Report. A) B) C) D) Ans: A) B) C) D) Ans: Offering prisoners a $50.00 payment for 22. participation in a clinical trial for toothpaste violates which of the following? The right to self-determination The right to full disclosure The right to protection from exploitation The right to privacy A Feedback: Offering money to low-income groups is viewed as mildly coercive and a violation of the right to self-determination because the participants may consent to a study because they need the money rather than because they fully consent to the conditions of the study. The right to protection from exploitation means that involvement in a study should not place participants at a disadvantage. The right to full disclosure means that the researcher must fully describe the study, the person's right to refuse participation, and possible risks and benefits. The right to privacy means that participants have the right to expect that any data they provide will be kept in strict confidence. To protect the right to fair treatment, the researcher who seeks federal grant funding 23. for research is required to do which of the following? Include minority populations in their research study Disclose the benefits of the research to participants Offer participants a stipend for participation in the study Obtain informed consent from participants A Feedback: The right to fair treatment is an aspect of justice that requests researchers to include all groups that may benefit from research. Historically, researchers excluded women and minority groups, meaning study results were not generalizable to those groups. Disclosing the benefits of the research to participants protects their right of full disclosure. Offering participants a stipend for participation in the C) D) Ans: Offer participants a stipend for participation in the study Obtain informed consent from participants A Feedback: The right to fair treatment is an aspect of justice that requests researchers to include all groups that may benefit from research. Historically, researchers excluded women and minority groups, meaning study results were not generalizable to those groups. Disclosing the benefits of the research to participants protects their right of full disclosure. Offering participants a stipend for participation in the study is a possible violation of their right to self-determination. Obtaining informed consent from participants protects their right to self-determination and their right to full disclosure. CHG A) B) C) D) Ans: A) B) C) D) Ans: A) B) C) D) Ans: The research question, “What is the decisionmaking process among intensive care unit 1. nurses who decide to discuss spiritual issues with patients?” is which of the following? Most likely to be addressed using a quantitative approach Most likely to be addressed using a qualitative approach Not researchable Not appropriately worded B Feedback: Quantitative studies usually involve concepts that are fairly well developed and for which reliable methods of measurement have been (or can be) developed. Qualitative studies are often undertaken because a researcher wants to develop a rich and context-bound understanding of a poorly understood phenomenon. In this case, a qualitative approach would be most appropriate for addressing this question. Which of the following is a major source of 2. ideas for research problems? Select all that apply. Theories or conceptual frameworks Personal nursing experience Nursing code of ethics Nursing literature A, B, D Feedback: Common sources of ideas for nursing research problems are clinical experience, relevant literature, social issues, theory, and external suggestions.

A) B) C) D) Ans: A) B) C) D) Ans: In a research report, the statement of purpose is normally found where? In the abstract In the first paragraph of the report At the end of the introduction At the beginning of the method section C Feedback: Researchers most often state their purpose at the end of the introduction or immediately after the review of the literature. A problem statement is presented early in a research article and often begins with the first sentence after the abstract. The first paragraph of a research report is often the starting point of a problem statement. The method section describes the methods used in the research study. In a statement of purpose, the researcher often communicates information beyond the 6. substantive content through which of the following? The specification of the population to be studied The operational definition of the research variables The prediction of anticipated relationships among variables The choice of verbs that suggest the state of knowledge on the topic or the approach to be used D Feedback: In the statement of purpose researchers also communicate the manner in which they sought to solve the problem, or the state of knowledge on the topic, through their choice of verbs. The statement of purpose does not provide the operational definition of the research variables. In a quantitative study, a statement of purpose identifies the key study variables and their possible interrelationships, as well as the population of interest.

Select the best description for the following: “Is there a relationship between elective labor 13. induction and an unintended cesarean delivery?” It is a directional hypothesis It is a directional research question It is a non-directional hypothesis It is a non-directional research question D Feedback: The statement is a non-directional research question. It is non-directional because it does not indicate whether the researcher believes that elective labor induction will increase or decrease the likelihood of unintended cesarean delivery. It is a research question because it indicates the purpose of the study in the form of a question. It is not a hypothesis because it is not in the form of a statement. Select the best description for the following: “Children who watch an average of 2 or more 14. hours of television per day will have higher BMIs than children who watch less than 2 hours of TV per day.” It is a directional hypothesis It is a directional research question It is a non-directional hypothesis It is a non-directional research question A Feedback: Directional hypotheses, such as this one, specify not only the existence but the expected direction of the relationship between variables.

A non-directional B) C) D) Ans: A) B) C) D) Ans: A) B) C) D) Ans: It is a directional research question It is a non-directional hypothesis It is a non-directional research question A Feedback: Directional hypotheses, such as this one, specify not only the existence but the expected direction of the relationship between variables. The statement is not a nondirectional research question or a directional research question. A non-directional hypothesis does not stipulate the direction of the relationship. Which of the following statements, if used in 15. a hypothesis, is not readily testable by empirical means? Less than Meaning of More than Related to B Feedback: Hypotheses that do not make a relational statement are problematic. If a hypothesis lacks a phrase such as more than, less than, different from, related to, or something similar, it is not readily testable. “Meaning of” is not a relational phrase, and thus the hypothesis would not be readily testable by empirical means. A hypothesis that states there is no relationship between the independent 16. variable(s) and the dependent variable(s) is called which of the following? Non-directional hypothesis Null hypothesis Research hypothesis Simple hypothesis B Feedback: A null hypothesis is a hypothesis that states there is no relationship between the independent variable(s) and the dependent variable(s).

Which of the following statements made by a new nurse researcher indicate that he 17. correctly understands the purpose of using statistical analysis in quantitative research? Select all that apply. “Statistical analysis allows the formal testing of hypotheses.” “Statistical analysis might lead a researcher to reject a hypothesis.” “Statistical analysis provides proof of the relationships between variables.” “Statistical analysis supports inferences that a hypothesis is most likely correct (or most likely not correct).” A, B, D Feedback: Hypotheses are formally tested through statistical analysis. Researchers use statistics to test whether their hypotheses have a high probability of being correct (i.e., has a probability < .05). Statistical analysis does not provide proof, it only supports inferences that a hypothesis is probably correct (or not). Hypotheses are never proved (or disproved); rather, they are accepted or supported (or rejected). “Statistical analysis provides proof of the relationships between variables” indicates that the nurse educator does not understand the purpose of using statistical analysis of quantitative research.

Knowledge gap (what information do we currently know and what is lacking?) Problem identification (what is the overall problem? What is not working in the current situation?) Proposed solution (how will information gained from the proposed study contribute to the solution of this problem?) Sustainability (how long will we be able to sustain any changes made to the current status quo?) A, B, C Feedback: Sustainability is not usually included in a well-structured problem statement for nursing research. Problem identification, a proposed solution, and a knowledge gap are components of a well-structured problem statement for nursing research.

A study whose purpose is to explore or describe some phenomenon is likely to be an investigation of a littleresearched topic, often involving a qualitative approach, such as phenomenology or ethnography. The other answers are more likely to be from quantitative studies, as verbs such as test, evaluate, and compare suggest quantifiable variables and designs with scientific controls. If the problem statement from a proposed research study indicates the need to generate a theory relating to social processes (e.g., how 22. persons within a social group interact with one another), the study design will most likely be which of the following?

A meta-analysis appearing in the Cochrane Reviews A metasynthesis published in the journal Qualitative Health Research An experimental study published in the journal Research in Nursing & Health A systematic review published in the journal Nursing Research C Feedback: A primary source is the original description of a study prepared by the researcher who conducted it; a secondary source is a description of a study by another person. A meta-analysis appearing in the Cochrane Reviews, a metasynthesis published in the journal Qualitative Health Research, and a systematic review published in the journal Nursing Research are examples of secondary sources. Literature reviews should be based on primary source material. Which of the following is an important 2. characteristic of a high-quality literature review? Restricted to articles written in nursing journals Restricted to recent studies Full of opinions Reproducible, with justifiable decision rules D Feedback: Conducting a literature review is an art and a science. A high-quality review should be unbiased, thorough, and up-to-date. Also, a high-quality review is systematic. Decision rules for including or excluding a study should be explicit because a good review should be reproducible. This means that another diligent reviewer would be able to apply the same decision rules and come to similar conclusions about the state of evidence on the topic.

In conducting a subject search in an electronic 3. database, you would most likely initiate the search by typing in which of the following? An author's name Restrictions to the search A topic or keyword An ancestor or descendant C Feedback: You conduct a subject search by entering a subject heading, such as a topic or keyword into the search field. The subject names have hyperlinks so that we could expand the search by clicking on them or could also click on the author's name or on the journal. Restrictions to the search will place limitations on the subject search in an electronic database, but are not typed in to initiate the search. The ancestry approach (“footnote chasing”), in which citations from relevant studies are used to track down earlier research on which the studies are based (the “ancestors”) and the descendancy approach, finding later studies that proceeded from an early study, are other approaches to research, different from the subject search. A) B) C) D) Ans: In an electronic literature search, the searcher does not necessarily have to know the 4. database's subject headings for retrieving information on a topic because of the capability known as which of the following? Searching Mapping Restricting focus Copying B Feedback: Mapping is a feature that allows you to search for topics using your own keywords, rather than the exact subject heading used in the database. In searching a bibliographic database, users can do a keyword search that looks for terms in text fields of a database record (or that maps keywords onto the database's subject codes), or can search according to the subject heading codes themselves. Restricting focus and copying do not pertain to the database's subject headings for retrieving information on a topic. 5. A) B) C) D) Ans: The electronic database that focuses on the nursing and allied health literature is: CINAHL EMBASE Web of Knowledge MEDLINE A Feedback: Key resources for a research literature search are the bibliographic databases that can be searched electronically. For nurses, the CINAHL (Cumulative Index to Nursing and Allied Health Literature) and MEDLINE® (Medical Literature On-Line) databases are especially useful. Other useful bibliographic databases for nurses include the Web of Knowledge, and EMBASE (the Excerpta Medica database). The Web of Knowledge database is useful for a descendancy search strategy because of its strong citation indexes. Of these, only CINAHL is focused on nursing and allied health literature.

Other useful bibliographic databases for nurses include the Web of Knowledge, and EMBASE (the Excerpta Medica database). The Web of Knowledge database is useful for a descendancy search strategy because of its strong citation indexes. Of these, only CINAHL is focused on nursing and allied health literature. When doing a computerized search for 6. quantitative studies on a topic, which of the following statements is most accurate? The best place to begin is to use a search engine such as Yahoo or Google The primary keyword to use in the search typically would be the population The keywords to start the search typically would be the independent and dependent variables The specific subject headings used in each bibliographic database would have to be learned C Feedback: For quantitative studies, the keywords are usually the independent or dependent variables (i.e., at a minimum, the “I” and “O” of the PICO components), and perhaps the population. For qualitative studies, the keywords are the central phenomenon and the population. Google and Yahoo are not the best search engines to use when looking for nursing research; the more specialized bibliographic databases, such as CINAHL and MEDLINE, are preferable. One does not need to learn the specific subject headings used in each bibliographic database to conduct a search. D) Ans: A) B) C) D) Ans: A) B) The specific subject headings used in each bibliographic database would have to be learned C Feedback: For quantitative studies, the keywords are usually the independent or dependent variables (i.e., at a minimum, the “I” and “O” of the PICO components), and perhaps the population. For qualitative studies, the keywords are the central phenomenon and the population. Google and Yahoo are not the best search engines to use when looking for nursing research; the more specialized bibliographic databases, such as CINAHL and MEDLINE, are preferable. One does not need to learn the specific subject headings used in each bibliographic database to conduct a search. 7. Which of the following statements is true? The CINAHL database includes only journals The CINAHL database includes about 15 million records The CINAHL database uses the controlled vocabulary called MeSH to index entries Subject headings in CINAHL include substantive and methodologic topics D Feedback: CINAHL is an important electronic database for nurses. It covers references to hundreds of nursing and allied health journals, as well as to books, book chapters, and dissertations. CINAHL contains more than 1 million records, but not 15 million. Note that its subject headings include substantive headings, such as Music Therapy in Old Age, as well as methodologic (e.g., QuasiExperimental Studies) and sample characteristic headings (e.g., Male; Female). It is MEDLINE, not CINAHL, that uses the controlled vocabulary called MeSH to index entries. 8. Which of the following statements is true? The MEDLINE database can only be accessed through subscriptions with a commercial vendor PubMed provides access to MEDLINE free of charge PubMed does not allow users to find “related A) B) C) D) Ans: 8. Which of the following statements is true? The MEDLINE database can only be accessed through subscriptions with a commercial vendor PubMed provides access to MEDLINE free of charge PubMed does not allow users to find “related citations” for a previously identified record in MEDLINE A search in MEDLINE and CINAHL for a given keyword would yield identical results B Feedback: MEDLINE® covers about 5000 medical, nursing, and health journals and has more than 21 million records. MEDLINE® can be accessed for free on the Internet at the PubMed website. In a search conducted by the authors, the list of records in the two PubMed and CINAHL searches overlapped considerably, but new references were found in each search. After you have found a study that is a good exemplar of what you are looking for, you usually can search for similar studies in the database. In PubMed, for example, after identifying a key study, you could click on “Related Citations” on the right of the screen to locate similar studies. In the following CINAHL citation, to what does the “6” refer? 9. Nursing Research 2012 Nov/ Dec; 61(6): 405-411.

Five recent studies have proved that men are less well able to cope with the loss of a spouse than women. The HIV-epidemic has been the cause of considerable anxiety in the gay community. Nurses and physicians struggle with the decision about whether to work in environments where abortion services are offered. Research has consistently found that infant's sleeping position is related to the risk of sudden infant death syndrome. D Feedback: A written research review should provide readers with an objective, well-organized synthesis of current evidence on a topic. The review should be as unbiased as possible. The sentence, “The HIV-epidemic has been the cause of considerable anxiety in the gay community,” presents subjective data, as does the sentence, “Nurses and physicians struggle with the decision about whether to work in environments where abortion services are offered.” A literature review should be neither a series of quotes nor a series of abstracts such as, “Five recent studies have proved that men are less well able to cope with the loss of a spouse than women.” The central tasks are to summarize and critically evaluate the evidence to reveal the current state of knowledge on a topic— not simply to describe what researchers have done. 11. A) B) C) D) Ans: A) B) C) D) Ans: What is the primary purpose of the review of literature in a research report? Reporting on the state of the current evidence about the problem under study Demonstrating the research capabilities of the authors Focusing on the gaps in research related to the problem under study Making recommendations about future study designs A Feedback: A literature review is a written summary of the state of evidence on a research problem. The primary purpose of literature reviews is to integrate research evidence to sum up what is known and what is not known. Literature reviews are sometimes standalone documents intended to share the state of evidence with interested readers, but reviews are also used to lay the foundation for new studies. At what point in the research process do 12. grounded theory qualitative researchers conduct a literature review? Prior to data collection After beginning to collect data At the conclusion of the study Prior to sample selection B Feedback: Grounded theory researchers typically begin to collect data before examining the literature. As the grounded theory takes shape, researchers then turn to the literature, seeking to relate prior findings to the theory. A) B) C) D) Ans: A) B) C) D) Ans: What is the most important type of 13. information that should be included in a literature review? Clinical anecdotes Opinion articles Case reports from applicable clinical settings Findings from prior studies D Feedback: Findings from prior studies are the most important type of information for a research review. What term is used to describe accounts of research in the literature prepared by 14. someone other than the researchers who conducted the study? Primary sources Secondary sources Ghost writer studies Literature reviews B Feedback: Secondary sources are written reports on studies prepared by someone other than the researcher who conducted the study. Primary sources, on the other hand, are descriptions of studies written by the researchers who conducted them. A literature review is a type of secondary source that consists of a written summary of the state of evidence on a research problem. “Ghost writer” is not a type of research study. 15. A) B) C) D) Ans: A) B) C) D) Ans: What is the first step in writing a review of literature? Determine the question to be addressed Select the bibliographic database to use Specify the medical subject headings to use Conduct an Internet search engine search A Feedback: Conducting a literature review is a little bit like doing a full-fledged study: a reviewer must start with a question, such as an EBP question (Chapter 2) or a question for a new study (Chapter 6). The reviewer then must gather, analyze, and interpret the information, and summarize the “findings” in a written product. Selecting a bibliographic database and specifying the medical subject headings to use are later steps in the process. Using common Internet search engines such as Google or Yahoo is not recommended for nursing research, as they tend to provide far too many irrelevant hits. Which search strategy selects an important 16. early study and locates subsequent citations in the literature? Ancestry approach Database search Descendancy approach Footnote chasing C Feedback: The descendancy approach identifies an early key study and uses citation indexes to locate later studies that cite the original study. Another approach is to search for evidence in bibliographic databases. Yet another strategy is the ancestry approach (“footnote chasing”), in which citations from relevant studies are used to track down earlier research on which the studies are based (the “ancestors”). A) B) C) D) Ans: Which electronic database would you first 17. use to access nursing and allied health literature? CINAHL MeSH Google MEDLINE A Feedback: CINAHL is the Cumulative Index for Nursing and Allied Health Literature and provides references for nursing and allied health journals, books, book chapters, and ® dissertations. The MEDLINE database, developed by the U.S. National Library of Medicine, is the premier source for bibliographic coverage of the biomedical literature. MEDLINE® uses a controlled vocabulary called MeSH (Medical Subject Headings) to index articles. MeSH terminology provides a consistent way to retrieve information that may use different terminology for the same concepts. Google is a general Internet search engine that would not be useful for accessing nursing and allied health literature. A) B) C) D) Ans: What term is given to unique symbols that expand search results and allow for a 18. simultaneous search of numerous words of the same root within an electronic database? Textword search Keywords Wildcard characters Expanders C Feedback: Wildcard characters such as * or $ are used in electronic databases to search for related words. An example would be that “nurs*” typed in a database may yield results that include nurse, nurses, and nursing. A keyword is a word or phrase that captures the key concepts in your question. A textword search looks for your keyword in the text fields of the records, i.e., in the title and the abstract. “Expanders” is not a term related to electronic database searches. A) B) C) D) Ans: What mechanism does the MEDLINE 19. database use to provide consistency in information retrieval? Textwords MeSH terminology Boolean operators Scopus reviews B Feedback: MeSH (Medical Subject Headings) terminology is a controlled vocabulary used in MEDLINE that provides a consistent way to retrieve information that may use different terminology for the same concepts.. A textword search looks for your keyword in the text fields of the records, i.e., in the title and the abstract. Boolean operators (such as “and” and “or”) can be used to expand or restrict a search. For example, if you wanted citations on lung cancer and smoking, you could enter the following: lung cancer AND smoking. The Boolean operator AND would restrict the search to citations with both lung cancer and smoking as textwords or subject headings. The Boolean operator “OR” expands a search—if you entered lung cancer OR smoking, you would retrieve all references with either term. Scopus is a bibliographic database useful for nurses. A) B) C) D) Ans: You have identified 66 potential references through electronic database searches for your review of literature. Which action in 20. the screening process would be the most appropriate next step in identifying the most useful articles? Comparing databases for duplicatereferenced reports Evaluating the heading terms Reading each article in detail Reviewing the abstracts D Feedback: Although reading each article in detail would allow you to evaluate each reference in terms of relevance, reviewing the abstracts would be most time efficient. Evaluating the heading terms in the articles would not be helpful in identifying the most useful articles, because they would not tell you enough information about the article. Comparing databases for duplicatereferences reports would also not be useful for this purpose. 21. A) B) C) D) Ans: What is the primary purpose in documenting the literature retrieval process? Ensuring approval by the Institutional Review Board (IRB) Preventing duplication of located references Providing a history of useful search words Simplifying preparation of the reference list B Feedback: Documentation will help you to conduct a more efficient search by preventing unintended duplication, and will also help you to assess what else needs to be tried. Although documentation does provide a history of useful search words and may simplify preparation of the reference list, neither of these is the primary purpose. Documentation does not ensure approval by the Institutional Review Board (IRB). A) B) C) D) Ans: What is the primary question that should be 22. addressed when evaluating published research reports in a literature review? To what extent do the findings reflect the truth (the true state of affairs)? Have the authors conducted an adequate literature review in their research report? Did the authors cite appropriately from the previously published literature related to the problem under study? Was the research question appropriate considering the available evidence at the time of the study? A Feedback: In literature reviews, methodological features of the studies under review need to be assessed with an eye to answering a broad question: To what extent do the findings reflect the truth (the true state of affairs) or, conversely, to what extent do flaws undermine the believability of the evidence? The “truth” is most likely to be discovered when researchers use powerful designs, good sampling plans, high-quality data collection procedures, and appropriate analyses. A) B) C) D) Ans: Identifying patterns, regularities, and irregularities in the published literature about 23. the problem under study when constructing a literature review is a process called which of the following? Structuring Sorting Content organizing Thematic analysis D Feedback: Once relevant studies have been retrieved, abstracted, and critiqued, the information has to be analyzed and synthesized. A thematic analysis essentially involves detecting patterns and regularities—as well as inconsistencies. Sorting, content organizing, and structuring are later steps undertaken when preparing a written literature review. A) B) C) D) Ans: Which statement accurately reflects a 24. characteristic of a well-written literature review? Only a few key reports by the same author should be included if that author has published extensively on the topic under study. The review should primarily contain reports supportive of your general hypothesis about the problem under study. The review should include reports that both support and contradict your own ideas. The review should clearly identify points that have been proven by previous research. C Feedback: A well-written literature review includes a comprehensive and objective summary of the published literature related to the problem under study. That means inclusion of reports that both support and refute your hypothesis. The other answers do not necessarily characterize a well-written literature review. 25. A) B) C) D) Ans: Which verbiage is most likely found in a well-written research review? “The hypothesis in this study was supported by the research findings.” “Results from this study proved that nursing actions were instrumental to improved patient outcomes.” “All of these studies verify that levels of understanding cannot be changed easily.” “It is clear that the presence of nurses improves the health status of patients in the clinical setting.” A Feedback: Hypotheses cannot be proved or disproved, rather they are supported by the published reports. CHS 1. A) B) C) D) Ans: 2. A) B) C) D) Ans: A set of logically interrelated propositions is associated with which of the following? Schematic model Conceptual model Classical theory Descriptive theory C Feedback: In the classical use of theory, researchers test hypotheses deduced from an existing theory. An emerging trend is the testing of theorybased interventions. Concepts are also the basic elements of conceptual models, but concepts are not linked in a logically ordered, deductive system. Schematic models (or conceptual maps) are graphic representations of phenomena and their interrelationships using symbols or diagrams and a minimal use of words. Descriptive theory thoroughly describes a phenomenon. The power of theories lies in their ability to do which of the following? Explain large segments of human experience Minimize the number of words required to explain phenomena and, thereby, eliminate semantic problems Prove conclusively that relationships exist among the phenomena studied Articulate the nature of relationships among phenomena D Feedback: A theory is an abstract generalization that systematically explains relationships among phenomena, but does not prove these relationships conclusively. Schematic models (or conceptual maps) are graphic representations of phenomena and their interrelationships using symbols or diagrams and a minimal use of words. Grand theories (or macro theories) attempt to describe large segments of the human experience, but this is not true of all theories. C) among the phenomena studied Articulate the nature of relationships among phenomena D Feedback: A theory is an abstract generalization that systematically explains relationships among phenomena, but does not prove these relationships conclusively. Schematic models (or conceptual maps) are graphic representations of phenomena and their interrelationships using symbols or diagrams and a minimal use of words. Grand theories (or macro theories) attempt to describe large segments of the human experience, but this is not true of all theories. D) Ans: 3. A) B) C) D) Ans: A) B) C) D) Ans: The building blocks of theory are which of the following? Frameworks Relationships Concepts Hypotheses C Feedback: As classically defined, theories consist of concepts and a set of propositions that form a logically interrelated system, providing a mechanism for deducing hypotheses from the original propositions. Schematic models (or conceptual maps) visually represent relationships among phenomena, and are used in both qualitative and quantitative research. Like theories, conceptual models can serve as springboards for generating hypotheses. 4. Every study has which of the following? Theory Schematic model Framework Conceptual model C Feedback: A framework is the conceptual underpinning of a study. Not every study is based on a theory or conceptual model, but every study has a framework. Schematic models (or conceptual maps) are graphic representations of phenomena and their interrelationships using symbols or diagrams and a minimal use of words; not every study has a schematic model. B) C) D) Ans: Schematic model Framework Conceptual model C Feedback: A framework is the conceptual underpinning of a study. Not every study is based on a theory or conceptual model, but every study has a framework. Schematic models (or conceptual maps) are graphic representations of phenomena and their interrelationships using symbols or diagrams and a minimal use of words; not every study has a schematic model. 5. A) B) C) D) Ans: 6. A) B) C) D) Ans: Which of the following is true of both theories and conceptual models? They are invented or created, not discovered. They need to be borrowed from other disciplines for nursing studies. They contain a set of logically interrelated propositions. They are different words for exactly the same thing. A Feedback: Theories and conceptual models are invented or created, not discovered. A theory, but not a conceptual model, consists of concepts and a set of propositions that form a logically interrelated system, providing a mechanism for deducing hypotheses from the original propositions. Several conceptual models of nursing have been used in nursing research, so they do not need to be borrowed from other disciplines. The Health Promotion Model would best be described as which of the following? Descriptive theory Borrowed theory Grounded theory Middle-range theory D Feedback: Examples of middle-range theories that have been used in research include Beck's (2012) Theory of Postpartum Depression; the Theory of Unpleasant Symptoms (Lenz et al., 1997), Kolcaba's (2003) Comfort Theory, Pender's Health Promotion Model, and Mishel's Uncertainty in Illness Theory (1990). Middle- B) C) D) Ans: A) B) C) D) Ans: Borrowed theory Grounded theory Middle-range theory D Feedback: Examples of middle-range theories that have been used in research include Beck's (2012) Theory of Postpartum Depression; the Theory of Unpleasant Symptoms (Lenz et al., 1997), Kolcaba's (2003) Comfort Theory, Pender's Health Promotion Model, and Mishel's Uncertainty in Illness Theory (1990). Middlerange theories are specific to certain phenomena. Descriptive theory thoroughly describes a phenomenon. Non-nursing models used by nurse researchers (e.g., Bandura's Social Cognitive Theory) are referred to as borrowed theories; when the appropriateness of borrowed theories for nursing inquiry is confirmed, the theories become shared theories. Some qualitative researchers seek to develop grounded theories, data-driven explanations to account for phenomena under study through inductive processes. Which of the following are central concepts in 7. conceptual models of nursing? Select all that apply. Human beings Social support Health Environment A, C, D Feedback: The concepts central to models of nursing are human beings, environment, health, and nursing. Social supports are not a concept central to models of nursing. 8. A) B) C) D) Ans: The nurse-theorist Roy developed which of the following? Uncertainty in Illness Model Health Promotion Model Adaptation Model Theory of Stress and Coping C Feedback: An example of a model of nursing used by nurse researchers is Roy's Adaptation Model.

Mishel's Uncertainty in Illness Theory (Mishel, 1990) focuses on the concept of uncertainty—the inability of a person to determine the meaning of illness-related events. Nola Pender's (2006) Health Promotion Model (HPM) focuses on explaining health-promoting behaviors, using a wellness orientation. Lazarus and Folkman's (1984, 2006) Theory of Stress and Coping offers an explanation of people's methods of dealing with stress. 9. A) B) C) D) Ans: 10. A) B) C) D) Ans: The nurse-theorist Pender developed which of the following? Adaptation Model Social Cognitive Theory Health Belief Model Health Promotion Model D Feedback: Pender's (2006) Health Promotion Model (HPM) focuses on explaining healthpromoting behaviors, using a wellness orientation. An example of a model of nursing used by nurse researchers is Roy's Adaptation Model. The Social Cognitive Theory was developed by Bandura, and the Health Belief Model was developed by Becker. The nurse-theorist Mishel developed which of the following? Uncertainty in Illness Theory Health Promotion Model Adaptation Model Transtheoretical Model A Feedback: Mishel's Uncertainty in Illness Theory (Mishel, 1990) focuses on the concept of uncertainty—the inability of a person to determine the meaning of illness-related events. Pender's (2006) Health Promotion Model (HPM) focuses on explaining healthpromoting behaviors, using a wellness orientation.

Pender's (2006) Health Promotion Model (HPM) focuses on explaining healthpromoting behaviors, using a wellness orientation. An example of a model of nursing used by nurse researchers is Roy's Adaptation Model. Prochaska developed the Transtheoretical Model. 11. A) B) C) D) Ans: A) B) C) D) Ans: The Theory of Stress and Coping is an example of which of the following? A nursing model A grand theory A borrowed theory A grounded theory C Feedback: An example of a model of nursing used by nurse researchers is Roy's Adaptation Model. Grand theories (or macro theories) attempt to describe large segments of the human experience. Non-nursing models used by nurse researchers (e.g., Bandura's Social Cognitive Theory) are referred to as borrowed theories; when the appropriateness of borrowed theories for nursing inquiry is confirmed, the theories become shared theories. The Theory of Stress and Coping is an example of a borrowed theory. Some qualitative researchers seek to develop grounded theories, data-driven explanations to account for phenomena under study through inductive processes. Self efficacy is a widely-used construct that 12. was originally developed within which of the following? The Health Belief Model The Health Promotion Model Social Cognitive Theory The Uncertainty in Illness Theory C Feedback: Social Cognitive Theory (Bandura, 1985, A) B) C) D) Ans: Self efficacy is a widely-used construct that 12. was originally developed within which of the following? The Health Belief Model The Health Promotion Model Social Cognitive Theory The Uncertainty in Illness Theory C Feedback: Social Cognitive Theory (Bandura, 1985, 2001), which is sometimes called selfefficacy theory, offers an explanation of human behavior using the concepts of selfefficacy, outcome expectations, and incentives. Becker's Health Belief Model (HBM) is a framework for explaining people's health-related behavior, such as health-care use and compliance with a medical regimen. Nola Pender's (2006) Health Promotion Model (HPM) focuses on explaining healthpromoting behaviors, using a wellness orientation. Mishel's Uncertainty in Illness Theory (Mishel, 1990) focuses on the concept of uncertainty—the inability of a person to determine the meaning of illnessrelated events. 13. A) B) C) D) Ans: Stages of change is a construct that was developed within which of the following? The Health Belief Model The Transtheoretical Model Health as Expanding Consciousness Model The Theory of Planned Behavior B Feedback: In the Transtheoretical Model (Prochaska et al., 2002), the core construct is stages of change, which conceptualizes a continuum of motivational readiness to change problem behavior. Becker's Health Belief Model (HBM) is a framework for explaining people's health-related behavior, such as health-care use and compliance with a medical regimen. The Theory of Planned Behavior (TPB; Ajzen, 2005), which is an extension of another theory called the Theory of Reasoned Action, offers a framework for understanding people's behavior and its psychological determinants. Rosa (2011) based her study of the process of transformative nursing practice in caring for patients with a chronic illness in Margaret Newman's (1997) Theory of Health as Expanding Consciousness.

A) B) C) D) Ans: A grounded theory often has as a theoretical underpinning which of the following? An ideational theory Symbolic interactionism Phenomenology The Theory of Human Becoming B Feedback: Some qualitative researchers seek to develop grounded theories, data-driven explanations to account for phenomena under study through inductive processes. A popular theoretical underpinning of grounded theory research is symbolic interaction (or interactionism), which has three underlying premises (Blumer, 1986). In some qualitative research traditions (e.g., phenomenology), the researcher strives to suspend previously held substantive theories of the specific phenomena under study, but each tradition has rich theoretical underpinnings. Ideational theories, a type of cultural theory, suggest that cultural conditions and adaptation stem from mental activity. The Theory of Human Becoming (Parse, 1999) has been called a nursing grand theory.

The belief that a child with Attention Deficit Hyperactivity Disorder will learn appropriate behaviors from continued positive reinforcement of acceptable behavior patterns 15. can generate a research hypothesis. This generalization of the relationship between phenomena is known as which of the following? Null Hypothesis Theory Model Framework B Feedback: Classically, theory is defined as an abstract generalization that explains how phenomena are interrelated. The relationships in this case are between the concepts of ADHD and positive reinforcement. Models are more loosely structured than theories and deal more in abstracts. Frameworks relate to the conceptual underpinnings of a study. A null hypothesis suggests that no relationship exists between concepts. In this case, we are looking at the relationship between ADHD and positive reinforcement with the hypothesis that a relationship does exist.

The connection of phenomena through a loosely structured approach not directly 16. linking them in a logically deductive manner is which of the following? Middle range theory Theoretical framework Conceptual model Research question C Feedback: Conceptual models focus on abstracts and therefore are loosely structured, presenting an understanding of the phenomena and a philosophical view of the design. They do not link concepts in a logically derived deductive system. Middle-range theories, compared with grand theories, are more specific and more amenable to empirical testing. In a study based on a theory, the framework is called the theoretical framework. A research question specifically poses the research problem being studied, such as the following: Does hand washing reduce hospital-acquired infections? A) B) C) D) Ans: Identify the type of research that often fails to formally acknowledge the conceptual 17. underpinnings or framework of the study since it is not necessarily part of the research tradition. Quantitative research Qualitative research Pilot study Mixed method research A Feedback: Quantitative studies look at the research problem, research question, and hypothesis from a statistical approach, which does not necessarily have a conceptual framework basis. In qualitative studies, the framework is part of the research tradition in which the study is based. A pilot study can be of either a quantitative, qualitative, or mixed-method approach, thereby having some acknowledgement of the conceptual framework. 18. A) B) C) D) Ans: Which of the following concepts are central to nursing models? Select all that apply. Human beings Environment Health Nutrition A, B, C Feedback: Human beings, environment, and health are three of the four concepts central to models of nursing, with nursing being the fourth, as opposed to nutrition. These conceptual models have been defined and linked in diverse ways to emphasize the relationship among them. A) B) C) D) Ans: A) B) C) D) Ans: Research on the recovery process of young adults following post-traumatic amputation of 19. a lower extremity would best be furthered by using which of the following conceptual models of nursing? Bandura's Social Cognitive Theory Prochaska's Transtheoretical Model Becker's Health Belief Model Sister Callista Roy's Adaptation Model D Feedback: In the Adaptation Model, humans are considered adaptive systems that cope with change through adaptation. A patient with an amputation of a lower extremity would have the need to cope with this loss and adapt to the change in mobility resultant from the trauma. Social Cognitive Theory (Bandura, 1985, 2001), which is sometimes called selfefficacy theory, offers an explanation of human behavior using the concepts of selfefficacy, outcome expectations, and incentives. Self-efficacy concerns people's belief in their own capacity to carry out particular behaviors (e.g., smoking cessation). In the Transtheoretical Model (Prochaska et al., 2002), the core construct is stages of change, which conceptualizes a continuum of motivational readiness to change problem behavior. Becker's Health Belief Model (HBM) is a framework for explaining people's healthrelated behavior, such as health-care use and compliance with a medical regimen.

To provide a mechanism for deducing hypotheses To stimulate new research To explain relationships among phenomena To determine the research design and methods of data collection A, B, C Feedback: Classically, theory is defined as an abstract generalization that explains how phenomena are interrelated. As classically defined, theories consist of concepts and a set of propositions that form a logically interrelated system, providing a mechanism for deducing hypotheses from the original propositions. Theories can also help to stimulate research by providing both direction and impetus. The research design and methods of data collection are directly related to the research problem and research question and are not primarily determined by the theory. Conceptual models of nursing are used by nurse researchers as an inspiration in formulating research questions and directing 22. research hypotheses. Some of the concepts that form these models include which of the following? Select all that apply. Health promotion Unified whole Adaptation Self-efficacy A, B, C Feedback: Health promotion, unified whole, and adaptation are conceptual models theorized by Pender, Rogers, and Roy, respectively, all A) B) C) D) Ans: A) B) C) D) Ans: A) B) C) D) Ans: following? Select all that apply. Health promotion Unified whole Adaptation Self-efficacy A, B, C Feedback: Health promotion, unified whole, and adaptation are conceptual models theorized by Pender, Rogers, and Roy, respectively, all nurse theorists. Self-efficacy comes out of Bandura's Social Cognitive Theory and is considered a non-nursing theory frequently used in nursing studies. Theories are created and invented as opposed 23. to being discovered. Theories are built inductively from which of the following? Observations Correlations Research questions Research problems A Feedback: Theory and research have a reciprocal relationship. Theories are built inductively from observations, and research is an excellent source for those observations. The theory, in turn, must be tested by subjecting deductions from it (hypotheses) to systematic inquiry. Thus, research plays a dual and continuing role in theory building and testing. Correlations, research questions, and research problems are part of the research designs that validate or test the relationship between concepts. Visual representation of the relationships among phenomena used in both quantitative 24. and qualitative research is known as which of the following?

Although theories and frameworks build through concepts they are not necessarily always depicted through a schematic representation. The five stages of change of the 25. Transtheoretical Model include which of the following? Select all that apply. Precontemplation Action Evaluation Maintenance A, B, D Feedback: Precontemplation, action, and maintenance are all part of the Transtheoretical Model. The second and third stages are contemplation and preparation. Evaluation is not a stage of change in this model. Which of the following theories are usually 26. adopted by ethnographers in the conduction of qualitative research? Select all that apply. Ideational theories Materialistic theories Substantive theories Preexisting theories A, B Feedback: Ethnographers adopt one of two cultural theories, ideational theories, which suggest that cultural conditions and adaptation stem from mental activity and ideas, or materialistic theories, which view material conditions as the source of cultural development. Substantive theory is a conceptualization of the target phenomenon being studied and can be used in any qualitative approach. Preexisting theories are frequently used in quantitative research. B) C) D) Ans: A) B) C) D) Ans: A) B) C) D) Ans: Materialistic theories Substantive theories Preexisting theories A, B Feedback: Ethnographers adopt one of two cultural theories, ideational theories, which suggest that cultural conditions and adaptation stem from mental activity and ideas, or materialistic theories, which view material conditions as the source of cultural development. Substantive theory is a conceptualization of the target phenomenon being studied and can be used in any qualitative approach. Preexisting theories are frequently used in quantitative research. Lazarus and Folkman's Theory of Stress and Coping has been used in nursing research to correlate the relationship between stress and 27. anxiety in primary caregivers of patients with dementia. This is an example of which of the following? Conceptual model Framework Shared theory Grounded theory C Feedback: The Theory of Stress and Coping is one of five non-nursing models or theories that have frequently been used in nursing studies, thus making it a shared theory. Grounded theory is a tradition of qualitative research. Concepts are the building blocks of theories. Theories can serve as the basis of a framework in a study although there is no specific indication above that it was used in a specific research study. Nursing theories that are more restricted in their generality and set out to explain a 28. smaller focus of the human experience are known as which of the following? Grand theories Middle-range theories Classical theories Propositions B Feedback: Middle-range theories explain a portion of the human experience such as decision-making or 28.

Which conceptual framework to use Whether there will be an intervention What types of comparisons will be made How many times data will be collected B, C, D Feedback: The research design is the overall plan for answering research questions. In quantitative studies, the design designates whether there is an intervention, the nature of any comparisons, methods for controlling confounding variables, whether there will be blinding, and the timing and location of data collection. Choosing a conceptual framework is not a significant part of the research design for quantitative studies but is more important in qualitative studies. Which of the following are key criteria for making causal inferences about the 2. relationship between two variables? Select all that apply. Lack of temporal ambiguity about which variable occurred first Statistical confirmation that a relationship between the two exists The ability to randomly assign study participants to groups The ability to rule out other factors as potential causes of the outcome A, B, D Feedback: Key criteria for inferring causality include: (1) a cause (independent variable) must precede an effect (outcome); (2) there must be a detectable relationship between a cause and an effect; and (3) the relationship between the two does not reflect the influence of a third (confounding) variable. The ability to randomly assign study participants to groups is not a key criterion for causality but rather is a method of preventing systematic bias.

The ability to randomly assign study participants to groups is not a key criterion for causality but rather is a method of preventing systematic bias. D) Ans: A) B) C) D) Ans: An important function of a rigorous research 3. design in a quantitative study is to have control over which of the following? Outcome variables Mediating variables Carryover variables Confounding variables D Feedback: Key criteria for inferring causality include: (1) a cause (independent variable) must precede an effect (outcome); (2) there must be a detectable relationship between a cause and an effect (mediating); and (3) the relationship between the two does not reflect the influence of a third (confounding) variable. A crossover design has the advantage of ensuring the highest possible equivalence among the people exposed to different conditions. Such designs are inappropriate for certain research questions, however, because of possible carryover effects. Outcome variables are not to be controlled but are the effect that is under study. Mediating variables are those through which another variable has an effect on the outcome variable. They do not need to be controlled. 4.

A) B) C) D) Ans: A) B) C) D) Ans: A true experiment requires which of the following? Select all that apply. Control Intervention Blinding Randomization A, B, D Feedback: Experiments (or randomized controlled trials, RCTs) involve an intervention (the researcher manipulates the independent variable by introducing an intervention; control (including the use of a control group that is not given the intervention and represents the comparative counterfactual); and randomization or random assignment (with participants allocated to experimental and control groups at random to make the groups comparable at the outset). Blinding is a means of controlling external sources of bias, but is not required or even feasible for all experiments. By keeping data collectors and others unaware of group allocation or study hypotheses, researchers minimize the risk that other people involved in the study will influence the results. The use of a random numbers table for 5. assigning subjects to groups eliminates which of the following? Selection threat Intervention fidelity Attrition Carryover effects A Feedback: A selection threat reflects biases stemming from preexisting differences between groups; use of random assignment via a random numbers table eliminates selection threat. Careful researchers pay attention to intervention fidelity—that is, they take steps to monitor that an intervention is faithfully delivered in accordance with its plan and that the intended treatment was actually received. Longitudinal studies are typically expensive, time-consuming, and subject to the risk of attrition (loss of participants over time), but yield valuable information about time-related phenomena.

Random assignment does not eliminate intervention fidelity, attrition, or carryover effects. 6. A) B) C) D) Ans: Which of the following is invariably present in quasi-experimental research? A control group An intervention Matching of subjects Randomization B Feedback: Quasi-experiments (trials without randomization) involve an intervention but lack randomization and, sometimes, a control group. Strong quasi-experimental designs introduce controls to compensate for these missing components. Matching of subjects is a method of controlling confounding variables by consciously forming comparable groups, which is used in some, but not all, quasiexperiments.

A) B) C) D) Ans: A one-group pretest-posttest design is an example of which of the following? A crossover design A true experimental design A quasi-experimental design A retrospective design C Feedback: Quasi-experiments involve an intervention but lack randomization and sometimes even a comparison group. Strong quasi-experimental designs introduce controls to compensate for these missing components. In crossover designs, people are exposed to more than one experimental condition in random order and serve as their own controls. Experiments involve an intervention; control; and randomization or random assignment. Retrospective designs involve collecting data about an outcome in the present and then looking back in time for possible causes. A pretest is to a posttest as which of the following? The placebo effect is to the Hawthorne effect A baseline measure is to a final outcome measure Blinding is to matching Attrition is to a mortality threat B Feedback: In pretest-posttest designs, data are collected both before the intervention (at baseline) and after it (outcome). The control group can undergo various conditions, including no treatment; an alternative treatment; a placebo C) D) Ans: A) B) C) D) Ans: measure Blinding is to matching Attrition is to a mortality threat B Feedback: In pretest-posttest designs, data are collected both before the intervention (at baseline) and after it (outcome). The control group can undergo various conditions, including no treatment; an alternative treatment; a placebo or pseudo intervention; standard treatment at different treatment doses; or a wait-list condition. In the Hawthorne effect, various environmental conditions vary to determine their effect on worker productivity. Blinding is another means of controlling external sources of bias. Matching is deliberately making groups comparable on some extraneous variables. Longitudinal studies are typically expensive, time-consuming, and subject to the risk of attrition (loss of participants over time). Mortality is the threat that arises from attrition in groups being compared. If different kinds of people remain in the study in one group versus another, then these differences, rather than the independent variable, could account for group differences in outcomes. One weakness associated with cause-probing 9. correlational research is which of the following? Artificiality of the settings in which it occurs Difficulty in linking the research to a theoretical framework Problem of self-selection into groups Inability to generalize the findings beyond the sample C Feedback: Correlational studies are susceptible to faulty interpretation because groups being compared have formed through self-selection (also called selection bias). When researchers study the effect of a cause they cannot manipulate, they use correlational designs that examine relationships between variables. A correlation is an interrelationship or association between two variables, that is, a tendency for variation in one variable to be related to variation in another. Correlations can be detected through statistical analyses.

Experimental Retrospective case-control Prospective cohort Quasi-experimental B Feedback: Retrospective designs (case-control designs) involve collecting data about an outcome in the present and then looking back in time for possible causes. Experiments are considered the gold standard because they come closer than any other design in meeting the criteria for inferring causal relationships. In prospective cohort designs, researchers begin with a possible cause, and then subsequently collect data about outcomes. Prospective studies are more costly, but much stronger, than retrospective studies. For one thing, any ambiguity about the temporal sequence of phenomena is resolved in prospective research (i.e., smoking is known to precede the lung cancer). Quasi-experiments (trials without randomization) involve an intervention but lack a comparison group or randomization. Strong quasi-experimental designs introduce controls to compensate for these missing components, and thus are generally stronger than non-experimental designs (including retrospective designs).

If a researcher wanted to describe the relationship between women's age and 11. frequency of performing breast selfexamination, the study would be classified as which of the following? Descriptive correlational Quasi-experimental Longitudinal Experimental A Feedback: Nonexperimental (observational) research includes descriptive research—studies that summarize the status of phenomena—and correlational studies that examine relationships among variables but involve no intervention or attempt to infer causal connections.

A) B) C) D) Ans: Studies that collect data at one point in time are called which of the following? Time series Cross-sectional studies Longitudinal studies Crossover studies B Feedback: Cross-sectional designs involve the collection of data at one time period, whereas longitudinal designs involve data collection at two or more times over an extended period. In a time-series design, outcome data are collected over a period of time before and after the intervention, usually for a single group. In crossover designs, people are exposed to more than one experimental condition in random order and serve as their own controls.

A) B) C) D) Ans: Constancy of conditions is often enhanced through which of the following? Collect data at the same time every day Using a crossover design Maximizing the external validity of the study Avoiding carryover effects A Feedback: Various external factors, such as the research environment, can affect outcomes. In carefully controlled quantitative research, steps are taken to minimize situational contaminants (i.e., to achieve constancy of conditions) so that researchers can be confident that outcomes reflect the influence of the independent variable and not the study context. Collecting data at the same time every day is an example of this. A crossover design involves exposing people to more than one treatment.

Construct validity External validity Intervention fidelity Internal validity B Feedback: External validity concerns inferences about whether relationships found for study participants might hold true for different people, conditions, and settings—in other words, generalizability. Using a homogeneous sample is easy, but one problem is limited generalizability. Indeed, one problem with this approach is that researchers may exclude people who are extremely ill or incapacitated, which means that the findings cannot be generalized to the very people who perhaps are most in need of interventions.

Using a homogeneous sample Statistical control Matching subjects Randomization D Feedback: Techniques for controlling subject characteristics include homogeneity (restricting participants to reduce variability on confounding variables); matching (deliberately making groups comparable on some extraneous variables); statistical procedures; and randomization—the most effective method because it controls all possible confounding variables without researchers having to identify them.

Maturation Selection Testing History D Feedback: The history threat is the occurrence of events concurrent with the independent variable that can affect the outcome. The maturation threat arises from processes occurring as a result of time (e.g., growth, fatigue) rather than the independent variable. The selection threat reflects biases stemming from preexisting differences between groups. RCTs have a clear superiority for testing causal hypotheses.

Intervention fidelity helps to avert biases and gives potential benefits a full opportunity to be realized. A counterfactual is what would have happened to the same people simultaneously exposed and not exposed to a causal factor. The effect is the difference between the two. A good research design for cause-probing questions entails finding a good approximation to the idealized counterfactual. The use of a diverse sample of study 23. participants in multiple sites might affect which of the following? Replicability of the study The ability to use randomization The ability to use blinding as a strategy The study's external validity D Feedback: External validity concerns inferences about generalizability—whether findings hold true over variations in people, conditions, and settings. Having a diverse sample of study participants in multiple sites would likely enhance the study's generalizability, and thus its external validity. The other answers would not necessarily be affected by a diverse sample of study participants in multiple sites. A) B) C) D) Ans: When participants' behaviors are affected not by the treatment per se but by their 24. knowledge of participating in a study, interpretation of the findings is complicated by the influence of which of the following? Treatment effect History threat Hawthorne effect Selection threat C Feedback: Hawthorne effect, in which various environmental conditions vary to determine their effect on worker productivity. The history threat is the occurrence of events concurrent with the independent variable that can affect the outcome. The selection threat reflects biases stemming from preexisting differences between groups. Temporal ambiguity, not treatment effect, the cause must precede the effect. 25. A) B) C) D) Ans: Which of the following can reduce the statistical conclusion validity of a study? Low attrition Low power Low generalizability Low maturation B Feedback: Statistical power refers to the capacity to detect true relationships. Statistical power can be achieved in various ways, the most straightforward of which is to use a large enough sample. With small samples, statistical power tends to be low, and the analyses may fail to show that the independent variable and the outcome are related—even when they are, thus reducing statistical conclusion validity. The other answers, although they may affect the study as a whole, do not reduce its statistical conclusion of validity.

The nurse is designing a research study to assess the effectiveness of two wound healing 26. dressings. What key design feature will be most important to address in this type of study? Intervention Comparisons Blinding Location B Feedback: The key design feature would be to address the use of comparisons. An intervention is a treatment. Location of the study would not be most important with regards to the design feature. Blinding refers to keeping certain information from research participants to minimize affecting the results via expectation bias. When addressing control of confounding variables, which of the following best 27. describes the question to be answered by the researcher?

Individuals who have suffered a myocardial infarction (MI) are at higher risk for a second MI within the next 5 years. Prolonged sun exposure is associated with higher rates of skin cancer. Hiatal hernias are diagnosed more frequently in elderly individuals. Taking time away from work leads to fewer stress-related illnesses. B Feedback: The statement, “Prolonged sun exposure is associated with higher rates of skin cancer” best illustrates causality. The other statements involve a greater likelihood that multiple variables could explain the effect, whereas the link between prolonged sun exposure and skin cancer is much stronger. Which of the statements below best illustrates 29. the temporal criterion needed for a causal relationship? Skin cancer occurs because of genetic predisposition. Kidney disease develops as a result of pesticide exposure. Hepatitis C occurs in populations with substance abuse histories.

Kidney disease develops as a result of pesticide exposure. Hepatitis C occurs in populations with substance abuse histories. Following vaccination for varicella, rates of varicella infection are lower. D Feedback: A cause must precede an effect in time. The answer “Following vaccination for varicella, rates of varicella infection are lower” best establishes that the suspected cause (vaccination) comes before the observed effect (decrease in varicella infection rates)..

A) B) C) D) Ans: Applying your knowledge of random assignment, which statement is correct? Random assignment is accomplished with random sampling. Grouping participants with similar features together is the best way to achieve random assignment. Random assignment ensures that the study is a true experiment. Recruiting participants from significantly different neighborhoods results in random assignment. C Feedback: Experimental designs involve placing participants in groups at random. Through randomization (or random assignment), every participant has an equal chance of being included in any group. Randomization is a critical characteristic of a true experimental Recruiting participants from significantly different neighborhoods results in random assignment. C Feedback: Experimental designs involve placing participants in groups at random. Through randomization (or random assignment), every participant has an equal chance of being included in any group. Randomization is a critical characteristic of a true experimental study. The other answers are not true of random assignment.

RXOX RORX RXOO ROXO D Feedback: Experimental designs can be depicted graphically using symbols to represent features of the design. In these diagrams, the convention is that R stands for randomization to treatment groups, X represents receipt of the intervention, and O is the measurement of outcomes. So, for example, a pretest-posttest design would be depicted as follows: R O X O. The other answers do not illustrate the correct order of elements. 33. A) B) C) D) Ans: Which statement infers the advantage to using cross-over designs for quantitative research? Enhances equivalence among participants exposed to different interventions. Different levels of the intervention are easily compared. Delaying the intervention highlights the effects of persuasion. Allows all participants to choose the intervention they will receive. A Feedback: In crossover designs, people are exposed to more than one experimental condition in random order and serve as their own controls. In cross-over designs, different levels of the Delaying the intervention highlights the effects of persuasion. Allows all participants to choose the intervention they will receive. A Feedback: In crossover designs, people are exposed to more than one experimental condition in random order and serve as their own controls. In cross-over designs, different levels of the interventions are not easily compared, and it does not allow participants of the study to choose interventions they will receive.

What research design should be selected for this study? Experimental Quasi-Experimental Cohort Nonexperimental D Feedback: A nonexperimental design should be selected for this study. When researchers do not intervene by controlling the independent variable, the study is nonexperimental, or, in the medical literature, observational. 37. A) B) C) D) Ans: A) B) C) D) Ans: Cross-sectional designs work best under what research conditions? Data collection over an extended period Multiple points of data collection Describing phenomena at a fixed point For follow-up studies C Feedback: Cross-sectional designs work best with describing phenomena at a fixed point. Crosssectional designs involve the collection of data at one time period. The other answers are characteristics of longitudinal studies. The nurse wishes to study the opinions of high school students concerning the availability of health care services at XYZ 38. High School during the past school year.

Cross-sectional What research design best fits with the study objective? Trend study Cross-sectional study Longitudinal study Follow-up study B Feedback: A cross-sectional study design would best fit with this study objective. Cross-sectional designs involve the collection of data at one time period, whereas longitudinal designs involve data collection at two or more times over an extended period. Cross-sectional designs are economical and easy to manage, and there is no need for inferring changes over time in this case. In nursing, most longitudinal studies are follow-up studies of clinical populations. Longitudinal studies are best for understanding trends over time.

Randomizing assignment to control treatment groups. Allowing for maximum flexibility over where data is collected. Choosing a heterogeneous sample of subjects. A Feedback: Use of a script to relay information about the study illustrates control over an external confounding variable-study context. Randomizing assignment to control the treatment groups, allowing for maximum flexibility over where data is collected, or choosing a heterogeneous sample of subjects does not illustrate control over an external confounding variable but pertain rather to those intrinsic to study participants. 40. A) B) C) D) Ans: What is the strongest method of controlling for intrinsic (subject) factors? Statistical control Randomization Matching Homogeneity B Feedback: 40. A) B) C) D) Ans: 41. A) B) C) D) Ans: A) B) C) D) Ans: What is the strongest method of controlling for intrinsic (subject) factors? Statistical control Randomization Matching Homogeneity B Feedback: The strongest method of controlling for intrinsic (subject) factors is randomization. It is the most effective method of controlling participants' characteristics. Homogeneity occurs when people who are similar in respect to confounding variables are included in the study. Matching involves consciously forming comparable groups. Statistical control is the ability to have control over confounding variables statistically. What study design flaw may lead to a failure to achieve statistical significance? Variables precisely defined Adequate exposure to the intervention Small sample size Cross-sectional data collection C Feedback: With small samples, statistical power tends to be low, and the analyses may fail to show that the independent variable and the outcome are related—even when they are. Variables that are precisely defined and have adequate exposure to the intervention and crosssectional data collection lead to statistical significance. Using your knowledge of threats to internal 42. validity, which research design will be most susceptible? Pretest-Posttest Cross-over Correlational Factorial C Feedback: A correctional research design is most susceptible to threats to internal validity. With quasi-experiments and correlational studies, there are competing explanations, which are sometimes called threats to internal validity. A) B) C) D) Ans: Pretest-Posttest Cross-over Correlational Factorial C Feedback: A correctional research design is most susceptible to threats to internal validity. With quasi-experiments and correlational studies, there are competing explanations, which are sometimes called threats to internal validity. 43. A) B) C) D) Ans: 44. A) B) C) D) Ans: Which situation best reflects “attrition” in quantitative research? Control and intervention groups are very different in age ranges. Subjects receive promotional materials about the benefits of the intervention. Adolescent subjects improve in body hygiene practices over 4 years. Control group subjects drop out of the study when their disease process does not improve. D Feedback: Mortality is the threat that arises from attrition in groups being compared. The most severely ill patients might drop out of the experimental condition because it is too demanding. Which quantitative research design will most strongly support evidence-based practice? Factorial Design Randomized Control Trial Design Correlational Design Time-Series Design B Feedback: A randomized control trial design will most strongly support evidence-based practice. Randomized controlled trials are the most powerful designs for testing hypotheses of cause-and-effect relationships. RCTs are the “gold standard” for intervention studies (Therapy questions) because they yield the highest-quality evidence about the effects of an intervention. A) B) C) D) Ans: A review of research reveals two articles that have conflicting results. A national randomized controlled trial found that annual brain scans will allow early detection and 45. treatment of brain cancers, reducing mortality by 65%. An international quasi-experimental trial reported no significant reduction in mortality with annual scans. Based on your review, propose the best recommendation. Recommendations from the national study should be followed. Recommendations from the international study should be followed. There is no rigorous research that can support a recommendation. Recommendations should be stratified according to where the research was conducted. A Feedback: Methodologically, the main design issue in quantitative studies is whether the research design provides the most valid, unbiased, and interpretable evidence possible. Indeed, there usually is no other aspect of a quantitative study that affects the quality of evidence as much as research design. RCTs are the “gold standard” for intervention studies (Therapy questions) because they yield the highestquality evidence about the effects of an intervention. Therefore, the best recommendation would be to follow the recommendations from the national randomized controlled trial because it is more authoritative than the quasi-experimental trial. A) B) C) D) Ans: A) B) C) D) Ans: A research proposal states that the objective is to, “explore the incidence of homeopathic health practices on Iowa Native Reserves in 46. Oklahoma.” In describing the design to be used for conducting the study, the researchers plan to use a nonexperimental design. What can you conclude from this proposal? The choice of a nonexperimental design is appropriate for the research objective. Researchers should consider using a quasiexperimental design to meet their objective. This research may not be answered completely if a quantitative design is used. The population to be studied needs to be expanded to include all Native Americans in Oklahoma to avoid a small sample size. C Feedback: The research may not be answered completely if a quantitative design is used, because the research question is not amenable to quantitative research. There are various reasons for doing a nonexperimental study, including situations in which the independent variable inherently cannot be manipulated (Prognosis questions) or in which it would be unethical to manipulate the independent variable (some Etiology questions). Experimental designs are also not appropriate for Descriptive questions. To study the effects of Healing Touch; what is 47. the best choice to minimize confounding variables? Offer a small payment for participants' time. Offer all participants a Healing Touch session when data collection is completed. Offer to enroll only individuals who do not have any medical conditions. Offer another activity that gives similar time and attention to control group participants. D Feedback: The best way to minimize confounding variables is to offer another activity that gives similar time and attention to control group participants—known as a placebo. Otherwise, the participant's knowledge of not receiving a C) D) Ans: have any medical conditions. Offer another activity that gives similar time and attention to control group participants. D Feedback: The best way to minimize confounding variables is to offer another activity that gives similar time and attention to control group participants—known as a placebo. Otherwise, the participant's knowledge of not receiving a treatment may affect the study's results. None of the other answers would control for this potential confounding variable. CHIO 1. A) B) C) D) Ans: 2. A) B) C) D) Ans: Sampling may be defined as which of the following? Selection of an accessible population for a study Selection of a subset of a population to represent the entire population Assignment of study participants to treatment groups Technique for ensuring that every element in the population has an equal chance of being included in the study B Feedback: Sampling is the process of selecting elements from a population, which is an entire aggregate of cases. An element is the basic unit of a population—usually humans in nursing research. Eligibility criteria (including both inclusion criteria and exclusion criteria) are used to define population characteristics. Researchers usually sample from an accessible population; a broader target population is the group to which they would like to generalize their results. A key criterion in assessing a sample in a quantitative study is its representativeness— the extent to which the sample is similar to the population and avoids bias. Bias in a sample for a quantitative study refers to which of the following? Lack of heterogeneity in the population on the attribute of interest Sample selection using nonprobability-type sampling methods The margin of error in the data obtained from samples Systematic over- or underrepresentation of a key attribute vis-a-vis the population D Feedback: Sampling bias is the systematic overrepresentation or underrepresentation of some segment of the population. Nonprobability sampling (in which elements are selected by nonrandom methods) includes convenience, quota, consecutive, and purposive sampling. A key criterion in C) samples Systematic over- or underrepresentation of a key attribute vis-a-vis the population D Feedback: Sampling bias is the systematic overrepresentation or underrepresentation of some segment of the population. Nonprobability sampling (in which elements are selected by nonrandom methods) includes convenience, quota, consecutive, and purposive sampling. A key criterion in assessing a sample in a quantitative study is its representativeness—the extent to which the sample is similar to the population and avoids bias. D) Ans: 3. A) B) C) D) Ans: 4. A) B) C) D) Ans: Strata are incorporated into the design of which of the following sampling approaches? Systematic Purposive Quota Consecutive C Feedback: Quota sampling divides the population into homogeneous strata (subpopulations) to ensure representation of the subgroups in the sample; within each stratum, people are sampled by convenience. Consecutive sampling involves taking all of the people from an accessible population who meet the eligibility criteria over a specific time interval, or for a specified sample size. In purposive sampling, participants are handpicked to be included in the sample based on the researcher's knowledge about the population. Systematic sampling is the selection of every kth case from a list. Which of the following is a probability sampling method? Convenience sampling Systematic sampling Consecutive sampling Quota sampling B Feedback: Systematic sampling is the selection of every kth case from a list and is an example of a probability sampling method.

Convenience sampling uses the most readily available or convenient group of people. Quota sampling divides the population into homogeneous strata (subpopulations) to ensure representation of the subgroups in the sample; within each stratum, people are sampled by convenience. Consecutive sampling involves taking all of the people from an accessible population who meet the eligibility criteria over a specific time interval, or for a specified sample size. The sampling design that would be especially 5. likely to yield a representative sample is which of the following? Consecutive Convenience Purposive Quota A Feedback: Consecutive sampling involves taking all of the people from an accessible population who meet the eligibility criteria over a specific time interval, or for a specified sample size. Convenience sampling uses the most readily available or convenient group of people. In purposive sampling, participants are handpicked to be included in the sample based on the researcher's knowledge about the population. Quota sampling divides the population into homogeneous strata (subpopulations) to ensure representation of the subgroups in the sample; within each stratum, people are sampled by convenience. A) B) C) D) Ans: A) B) C) D) Ans: Which of the following types of sample is 6. considered to be the weakest for quantitative studies? Convenience Quota Purposive Systematic A Feedback: Convenience sampling uses the most readily available or convenient group of people. The problem with convenience sampling is that people who are readily available might be atypical of the population, and so the price of convenience is the risk of bias. Convenience sampling is the weakest form of sampling, but it is also the most commonly used sampling method in many disciplines. In purposive sampling, participants are hand-picked to be included in the sample based on the researcher's knowledge about the population. Quota sampling divides the population into homogeneous strata (subpopulations) to ensure representation of the subgroups in the sample; within each stratum, people are sampled by convenience. Systematic sampling is the selection of every kth case from a list. A researcher used a systematic sampling plan. The sample size was 200. The sampling 7. interval was 250. The first element drawn was 196. The second element would be: 396 45 446 646 C Feedback: By dividing the population size by the desired sample size, the researcher establishes the sampling interval, which is the standard distance between the selected elements: 196 (first element) + 250 (sample interval) = 446 (second element). 396, 450, and 646 are incorrect responses. B) C) D) Ans: A) B) C) D) Ans: 45 446 646 C Feedback: By dividing the population size by the desired sample size, the researcher establishes the sampling interval, which is the standard distance between the selected elements: 196 (first element) + 250 (sample interval) = 446 (second element). 396, 450, and 646 are incorrect responses. Which of the following is the most widely 8. used data collection method by nurse researchers? Records Self-reports Observation Biophysiologic measures B Feedback: Data collection methods vary in terms of structure, quantifiability, and objectivity. The three principal data collection methods for nurse researchers are self-report, observations, and biophysiologic measures. Self-reports, which involve directly questioning study participants, are the most widely used method of collecting data for nursing studies. 9. A) B) C) D) Ans: A major advantage of closed-ended questions is that they do which of the following? Are easy to construct Are analyzed in a straightforward manner Encourage in-depth responses Are not subject to response biases B Feedback: Good closed-ended questions are more difficult to construct than open-ended ones but easier to analyze. Closed-ended questions are also more efficient: people can complete more closed-ended questions than open-ended ones in a given amount of time. People may be unwilling to compose lengthy written responses to open-ended questions in questionnaires. A major drawback of closedended questions is that researchers might omit some potentially important responses. Closedended questions also can be superficial.

Closed-ended questions are also more efficient: people can complete more closed-ended questions than open-ended ones in a given amount of time. People may be unwilling to compose lengthy written responses to open-ended questions in questionnaires. A major drawback of closedended questions is that researchers might omit some potentially important responses. Closedended questions also can be superficial. Openended questions allow for richer information if the respondents are verbally expressive and cooperative. Finally, some respondents object to choosing from alternatives that do not reflect their opinions precisely. Interviews are usually preferable to 10. questionnaires because of which of the following? They are less expensive They yield data that are easier to analyze The quality of the data tends to be higher They require less training of research personnel C Feedback: Interviews are usually preferable to questionnaires because the quality of the data tends to be higher. Researchers using structured self-reports must decide whether to use interviews or self-administered questionnaires. Questionnaires are less costly than interviews and offer the possibility of anonymity, but interviews yield higher response rates, are suitable for a wider variety of people, and provide richer data than questionnaires. 11. A) B) C) D) Questionnaires have the advantage of which of the following? Offering the possibility of anonymity Having high response rates Reducing the possibility of response set biases Being suitable for all types of study 11. A) B) C) D) Ans: A) B) C) D) Ans: Questionnaires have the advantage of which of the following? Offering the possibility of anonymity Having high response rates Reducing the possibility of response set biases Being suitable for all types of study participants A Feedback: Questionnaires are less costly than interviews and offer the possibility of anonymity, but interviews yield higher response rates (which reduce the risk for bias), are suitable for a wider variety of people, and provide richer data than questionnaires. Interviews are usually preferable to questionnaires because the quality of the data tends to be higher. Researchers using structured self-reports must decide whether to use interviews or selfadministered questionnaires. On a five-point Likert scale, a person who 12. strongly agreed with a statement would be scored as which of the following? 1 3 5 Cannot be determined D Feedback: Likert scales (or summated rating scales) present respondents with a series of items worded favorably or unfavorably toward a phenomenon; responses indicating level of agreement or disagreement with each statement are scored and summed into a composite score. The term needs to be indicated for each number in order to determine which number represents strongly agree or disagree. A) B) C) D) Ans: A) B) C) D) Ans: On a 20-item Likert scale with five response 13. categories, the range of possible scores is which of the following? 0 to 100 20 to 80 20 to 100 0 to 50 C Feedback: Likert scales (or summated rating scales) present respondents with a series of items worded favorably or unfavorably toward a phenomenon; responses indicating level of agreement or disagreement with each statement are scored and summed into a composite score. 20 items x a score of 1 per item is 20 as the minimum score and 20 items x a score of 5 per item are 100 as the maximum score. A self-report method used to measure 14. subjective experiences such as pain and fatigue is which of the following? Observation In vivo measurements Visual analog scales Likert scales C Feedback: A visual analog scale (VAS) is used to measure subjective experiences (e.g., pain, fatigue) along a 100 mm line designating a bipolar continuum. Observational methods are techniques for acquiring data through the direct observation of phenomena. Data may also be derived from biophysiologic measures, which include in vivo measurements (those performed within or on living organisms) and in vitro measurements (those performed outside the organism's body, such as blood tests). Biophysiologic measures have the advantage of being objective, accurate, and precise.

The social desirability response set bias is 15. least likely to be a problem on scales incorporated into which of the following? Mailed anonymous questionnaires Face-to-face interviews Telephone interviews All options are equally susceptible A Feedback: Social desirability response set bias—a tendency to misrepresent attitudes or traits by giving answers that are consistent with prevailing social views—would be least likely to be a problem with mailed anonymous questionnaires, as the anonymity would likely cause people to be less concerned about what others thought of their answers. A person who marked “strongly agree” to all 16. or most items on a Likert scale would best be described as which of the following? Socially desirable respondent Biased participant Nay-sayer Yea-sayer D A) B) C) D) Ans: A) B) C) D) Ans: A person who marked “strongly agree” to all 16. or most items on a Likert scale would best be described as which of the following? Socially desirable respondent Biased participant Nay-sayer Yea-sayer D Feedback: Acquiescence response set bias is a tendency to agree with statements regardless of their content; such responders are known as “yeasayers.” People who have the opposite tendency—to disagree with statements independently of the question content—are known as nay-sayers and are much less common. Social desirability response set bias is a tendency to misrepresent attitudes or traits by giving answers that are consistent with prevailing social views. A yea-sayer is a type of biased participant. When an observer is not concealed, the 17. findings may be biased because of which of the following? Reactivity Ethical problems Lack of mobility Acquiescence response set bias A Feedback: Researchers do not always tell people they are being observed, because awareness of being observed may cause people to behave atypically. A behavioral distortion due to the known presence of an observer is called reactivity. It is not an ethical problem or lack of mobility. Acquiescence response set bias is a tendency to agree with statements regardless of their content by some people (yea-sayers). The opposite tendency—to disagree with statements independently of the question content—is less common. A) B) C) D) Ans: Which of the following are advantages of 18. using biophysiologic measures in nursing studies? Select all that apply. They are relatively accurate and precise They effectively measure subjective experiences such as pain and fatigue They are objective, requiring minimal inference They are typically cost effective because they are available for clinical purposes A, C, D Feedback: Nurse researchers have used biophysiologic measures for a wide variety of purposes, and these measures have many advantages. They are relatively accurate and precise, objective, not easily distorted by patients, and valid. However, they cannot effectively measure subjective experiences such as pain and fatigue; a visual analog scale would be more appropriate for that. 19. A) B) C) D) Ans: Which of the following statements describes a population? All traumatic brain injury clients hospitalized in an intensive care unit during January 2012 Four hundred nurses selected from a membership list of American Nurses' Association (ANA) members Selected members of families of clients undergoing surgery A sample of clients diagnosed with COPD and who currently smoke A Feedback: All traumatic brain injury clients hospitalized in an intensive care unit during January 2012 denotes a population. A population is the entire group of interest. The other answers denote only samples or segments of a population. 20. A) B) C) D) Ans: 21. A) B) C) D) Ans: Which of the following results from a sample size that is too small? Low power to detect a difference in the outcomes of the two groups Lack of control over extraneous variables Limits to random sampling A weak questionnaire survey tool A Feedback: Sampling involves selecting a portion of the population to represent the population. A low power to detect a difference in the outcomes of the two group results from a sample size that is too small. The other answers are not effects of having a sample size that is too small. Which procedure describes a probability sampling method? Identification of community organizations and churches in an urban setting and recruiting participants Identification of individuals demonstrating the variable(s) of interest to the researcher and recruiting participants Identification of the accessible population and selecting study participants based upon the researcher's belief that the participant is representative of the accessible population Identification of a sampling frame for an accessible population, writing element names on paper, placing the written names in a bowl, and drawing a select number of names from the bowl D Feedback: Identification of a sampling frame for an accessible population, writing element names on paper, placing the written names in a bowl, and drawing a select number of names from the bowl describes a probability sampling method. This is because probability sampling involves random selection of elements from a population, which is achieved in this case by drawing names from a bowl. The other answers do not include random selection. D) on paper, placing the written names in a bowl, and drawing a select number of names from the bowl D Feedback: Identification of a sampling frame for an accessible population, writing element names on paper, placing the written names in a bowl, and drawing a select number of names from the bowl describes a probability sampling method. This is because probability sampling involves random selection of elements from a population, which is achieved in this case by drawing names from a bowl. The other answers do not include random selection. Ans: 22. A) B) C) D) Ans: Which statement regarding sampling error and sampling bias is accurate? Sampling bias may be defined as the difference between data obtained from a simple random sample and the data that would be obtained if an entire population were measured. Sampling bias occurs by chance. Sampling error and sampling bias are synonymous. Sampling error may be contained in sample data even when the most careful random sampling procedure has been used to obtain the sample. D Feedback: Sampling error may be contained in sample data even when the most careful random sampling procedure has been used to obtain the sample. There is no guarantee of a representative sample, but random selection does guarantee that differences between the sample and the population (sampling error) are purely a function of chance rather than of sampling bias. Sampling bias does not occur by chance and is not synonymous with sampling error. Sampling error, not sampling bias, is defined as the difference between data obtained from a simple random sample and the data that would be obtained if an entire population were measured. 23. A) B) C) D) Ans: A) B) C) D) Ans: Which group represents a convenience sample? The patients with a diagnosis of URI seen in the clinic on one afternoon in February One hundred male BSN nurses recruited by the original study subjects who are currently in leadership roles Middle-class Caucasian females chosen as representatives of the accessible population Twenty male subjects and twenty female subjects chosen for a study on gender differences A Feedback: Convenience sampling entails selecting the most conveniently available people as participants. A nurse who distributes questionnaires about vitamin use to 100 elders at a senior citizens center is sampling by convenience, for example. The problem with convenience sampling is that people who are readily available might be atypical of the population, and so the price of convenience is the risk of bias. Convenience sampling is the weakest form of sampling, but it is also the most commonly used sampling method in many disciplines. In this case, the best example of a convenience sample is “the patients with a diagnosis of URI seen in the clinic on one afternoon in February,” because the sample includes only those patients who happen to be at the clinic during a short time period. The other answers indicate other sampling designs, including quota and purposive sampling. Which sampling method would be most practical and provide the most reliable data to 24. study the medication errors by registered nurses who work in city, county, and federal prisons? Purposive sampling Stratified random sampling Quota sampling Simple random sampling B Feedback: A) B) C) D) Ans: A) B) C) D) Ans: practical and provide the most reliable data to 24. study the medication errors by registered nurses who work in city, county, and federal prisons? Purposive sampling Stratified random sampling Quota sampling Simple random sampling B Feedback: In stratified random sampling, the population is first divided into two or more strata, from which elements are randomly selected. The aim of stratified sampling is to enhance representativeness; as a type of probability sampling, it is more reliable than nonprobability sampling. This case would be ideal for stratified random sampling, as the population is readily divided into the strata of city, county, and federal prisons. Purposive sampling is based on the belief that researchers' knowledge about the population can be used to hand-pick sample members. Quota sampling occurs when researchers identify population strata and figure out how many people are needed from each stratum. Simple random sampling is the most basic probability sampling. If a target population contains 10,600 elements and the researcher seeks a 25. systematic random sample of 50, the sampling interval would be which of the following? 116 600 212 53 C Feedback: To obtain the sampling interval, the size of the population is divided by the size of the desired sample. 26. A) B) C) D) Ans: When is a small sample size appropriate for a research study? Many uncontrolled variables are present. The population is very homogenous. Large differences are expected in members of the population on the variable of interest. The population must be divided into subgroups. C 26. A) B) C) D) Ans: A) B) C) D) Ans: A) B) C) D) Ans: When is a small sample size appropriate for a research study? Many uncontrolled variables are present. The population is very homogenous. Large differences are expected in members of the population on the variable of interest. The population must be divided into subgroups. C Feedback: When expected differences are large, a large sample is not needed to reveal group differences statistically; but when small differences are predicted, large samples are necessary. In general, however, a larger sample size leads to less bias and greater reliability. A survey question asks subjects to respond to the following statement: “The overall hospital experience that I received during my hospital stay considered my needs as an individual.” 27. They were asked to identify, on a five-point scale, the degree to which they agreed or disagreed with the statement. This is an example of which scale? Social scale Likert scale Visual analog scale Differential scale B Feedback: A Likert scale consists of several declarative statements (items) that express a viewpoint on a topic. Respondents are asked to indicate how much they agree or disagree with the statement. This is an example of a Likert scale. Visual analog scales measure subjective experiences. There are no “social” or “differential” scales mentioned in this chapter. The nurse researcher is conducting a study on a nonpharmacologic nursing intervention for 28. the treatment of pain. Which data collection instrument would provide the most sensitive measurement of pain? Differential scale Physiologic measures Likert scale Visual analog scale D A) B) C) D) Ans: A) B) C) D) Ans: The nurse researcher is conducting a study on a nonpharmacologic nursing intervention for 28. the treatment of pain. Which data collection instrument would provide the most sensitive measurement of pain? Differential scale Physiologic measures Likert scale Visual analog scale D Feedback: A visual analog scale would provide the most sensitive measurement of pain, because it measures subjective experiences. Physiologic measures and the Likert scale do not effectively measure subjective experiences such as pain. There is no “differential scale.” Which of the following is an advantage of 29. observation as a method of data collection in a study? Subjects may be anxious because they are being observed. Respondents can remain anonymous. It is less time consuming than a questionnaire. It directly captures an event and behaviors. D Feedback: Observation directly captures an event and behaviors. Observational methods can be used to gather such information as the conditions of individuals, verbal communication, nonverbal communication, activities, and environmental conditions. Subject anxiety is not an advantage but a disadvantage of observation and may be eliminated by concealment. Respondents are not anonymous when observed, and observation is not less time consuming than a questionnaire. 30. A) B) C) D) Ans: Which of the following are advantages to biophysiologic measures? Biophysiologic measurements are subjective and accurate. Patients cannot distort the measurements and have objective measures. Biophysiologic measurements are selfreported. Biophysiologic measurements effectively indicate pain levels. B Feedback: 30. A) B) C) D) Ans: biophysiologic measures? Biophysiologic measurements are subjective and accurate. Patients cannot distort the measurements and have objective measures. Biophysiologic measurements are selfreported. Biophysiologic measurements effectively indicate pain levels. B Feedback: An advantage of biophysiologic measures is that patients cannot distort the measurements and they include objective measures. Biophysiologic measures include both in vivo and in vitro measures. Biophysiologic measures are accurate, precise, and objective. They are not self-reported and cannot effectively indicate pain levels. CH 99 A) B) C) D) Ans: A) B) C) D) Ans: The difference between a true score and an 1. obtained score is referred to as which of the following? Internal inconsistency Non-equivalence Interobserver disagreement Error of measurement D Feedback: The obtained (or observed) score is the value obtained from measurement. The true score is the true value that would be obtained if it were possible to have an infallible measure. The true score is hypothetical—it cannot be known because measures are not infallible. The final term in the equation is the error of measurement, which is the difference between true and obtained scores. When the reliability assessment focuses on equivalence between observers or coders assigning scores, estimates of interrater (or interobserver) reliability are obtained. Internal consistency reliability, which refers to the extent to which the entire instrument's items are measuring the same attribute, is usually assessed with Cronbach's alpha. The level of measurement that classifies and ranks people in terms of the degree to which 2. they possess the attribute of interest is which of the following? Nominal Ordinal Interval Ratio B Feedback: There are four levels of measurement: (1) nominal measurement—the classification of attributes into mutually exclusive categories; (2) ordinal measurement—the ranking of people based on their relative standing on an attribute; (3) interval measurement— indicating not only people's rank order but the distance between them; and (4) ratio measurement—distinguished from interval measurement by having a rational zero point and thus providing information about the B) C) D) Ans: Ordinal Interval Ratio B Feedback: There are four levels of measurement: (1) nominal measurement—the classification of attributes into mutually exclusive categories; (2) ordinal measurement—the ranking of people based on their relative standing on an attribute; (3) interval measurement— indicating not only people's rank order but the distance between them; and (4) ratio measurement—distinguished from interval measurement by having a rational zero point and thus providing information about the absolute magnitude of the attribute. 3. A) B) C) D) Ans: A) B) C) D) Ans: Blood type is measured on which of the following? Nominal scale Ordinal scale Interval scale Ratio scale A Feedback: There are four levels of measurement: (1) nominal measurement—the classification of attributes into mutually exclusive categories such as blood type; (2) ordinal measurement —the ranking of people based on their relative standing on an attribute; (3) interval measurement—indicating not only people's rank order but the distance between them; and (4) ratio measurement—distinguished from interval measurement by having a rational zero point and thus providing information about the absolute magnitude of the attribute. It is not meaningful to calculate an arithmetic 4. average with data from which of the following? Nominal measures Ordinal measures Nominal and ordinal measures All measures can be meaningfully averaged C Feedback: There are four levels of measurement: (1) nominal measurement—the classification of attributes into mutually exclusive categories such as blood type; (2) ordinal measurement A) B) C) D) Ans: A) B) C) D) Ans: Nominal measures Ordinal measures Nominal and ordinal measures All measures can be meaningfully averaged C Feedback: There are four levels of measurement: (1) nominal measurement—the classification of attributes into mutually exclusive categories such as blood type; (2) ordinal measurement —the ranking of people based on their relative standing on an attribute; (3) interval measurement—indicating not only people's rank order but the distance between them; and (4) ratio measurement—distinguished from interval measurement by having a rational zero point. It is not meaningful to calculate an arithmetic average with data from nominal and ordinal measures and thus providing information about the absolute magnitude of the attribute. Interval and ratio measurements can be meaningfully averaged, whereas nominal and ordinal measurements cannot. Type of college degree (associate's, 5. bachelor's, master's, doctorate) is measured on which of the following scales? Nominal Ordinal Interval Ratio B Feedback: There are four levels of measurement: (1) nominal measurement—the classification of attributes into mutually exclusive categories such as blood type; (2) ordinal measurement —the ranking of people based on their relative standing on an attribute such as type of college degree; (3) interval measurement— indicating not only people's rank order but the distance between them; and (4) ratio measurement—distinguished from interval measurement by having a rational zero point. College degrees are examples of ordinal measures, because they indicate a person's relative standing in terms of education, but do not indicate the distance between the measures.

One source of measurement error in social6. psychological scales is which of the following? Response-set bias Nonresponse bias Attrition bias Selection bias A Feedback: Response-set biases are enduring characteristics of respondents that can interfere with accurate measures. Sources of measurement error include situational contaminants, response-set biases, item sampling, and transitory personal factors. Nonresponse bias, attrition bias and selection bias are not examples of sources of measurement error. A measure of which of the following traits 7. would be a particularly good candidate for a test-retest reliability assessment?

Anxiety Fear of heights Mood Fatigue B Feedback: The stability aspect of reliability, which concerns the extent to which an instrument yields similar results on two administrations, is evaluated by test–retest procedures. Attitudes, mood, and so forth can be changed by experiences between two measurements. Thus, stability indexes are most appropriate for fairly enduring characteristics, such as temperament or fear of heights. Anxiety, mood, and fatigue are not fairly enduring characteristics. 8. A) B) C) D) Ans: A) B) C) D) Ans: Cronbach's alpha is used to assess which of the following attributes of an instrument? Internal consistency Stability Equivalence Sensitivity A Feedback: Internal consistency reliability, which refers to the extent to which all of the instrument's items are measuring the same attribute, is usually assessed with Cronbach's alpha. The stability aspect of reliability, which concerns the extent to which an instrument yields similar results on two administrations, is evaluated by test–retest procedures. Sensitivity is the instrument's ability to identify a case correctly (i.e., its rate of yielding true positives). Equivalence, in reliability assessment, primarily concerns the degree to which two or more independent observers or coders agree about scoring on an instrument. The aspect of reliability for which 9. interobserver reliability is appropriate is which of the following?

Stability Internal consistency Equivalence Specificity C Feedback: Equivalence, in reliability assessment, primarily concerns the degree to which two or more independent observers or coders agree about scoring on an instrument. Internal consistency reliability, which refers to the extent to which the entire instrument's items are measuring the same attribute, is usually assessed with Cronbach's alpha. The stability aspect of reliability, which concerns the extent to which an instrument yields similar results on two administrations, is evaluated by test– retest procedures. Specificity is the instrument's ability to identify non-cases correctly (i.e., its rate of yielding true negatives). If the coefficient alpha for a stress scale was 10. computed to be .80, the scale would be which of the following? More reliable than a scale with an alpha of .50 A valid indicator of stress Of indeterminate reliability until the scale's test–retest reliability was assessed Of unacceptably low reliability A Feedback: Internal consistency is evaluated by calculating coefficient alpha (or Cronbach's alpha). The normal range of values for this reliability index is from .00 to +1.00. The higher the coefficient, the more accurate (internally consistent) the measure. The type of validity that employs primarily 11. judgment in its assessment is which of the following? Content Concurrent Predictive Construct A A) B) C) D) Ans: A) B) C) D) Ans: The type of validity that employs primarily 11. judgment in its assessment is which of the following? Content Concurrent Predictive Construct A Feedback: Content validity concerns the sampling adequacy of the content being measured and is based on judgment. Expert ratings on the relevance of items can be used to compute a content validity index (CVI). Criterion-related validity (which includes both predictive validity and concurrent validity) focuses on the correlation between an instrument and an outside criterion. Construct validity, an instrument's adequacy in measuring the targeted construct, is a hypothesis-testing endeavor. Suppose a researcher were interested in assessing the adequacy of an instrument to measure the theoretical concept of 12. hopefulness. The most appropriate type of validation procedure would be which of the following? Content Concurrent Predictive Construct D Feedback: Construct validity, an instrument's adequacy in measuring the targeted construct, is a hypothesis-testing endeavor. Content validity concerns the sampling adequacy of the content being measured. Expert ratings on the relevance of items can be used to compute a content validity index (CVI). Criterion-related validity (which includes both predictive validity and concurrent validity) focuses on the correlation between an instrument and an outside criterion. 13. A) B) C) D) Ans: A) B) C) D) Ans: With screening or diagnostic instruments, the concept indicating the instruments' ability to 14. correctly identify a “case” (i.e., to screen in or diagnose a condition correctly) is which of the following? Sensitivity Stability Specificity Sensibility A Feedback: Sensitivity is the instrument's ability to identify a case correctly (i.e., its rate of yielding true positives). Specificity is the instrument's ability to identify non-cases correctly (i.e., its rate of yielding true negatives). The stability aspect of reliability, which concerns the extent to which an instrument yields similar results on two administrations, is evaluated by test–retest procedures. There is no research term known as sensibility. 15. A) B) C) Which of the following terms does not belong with the other three? Face validity Criterion-related validity Predictive validity Concurrent validity A Feedback: Face validity refers to whether an instrument looks as though it is measuring the appropriate construct. Criterion-related validity (which includes both predictive validity and concurrent validity) focuses on the correlation between an instrument and an outside criterion. Which of the following is an example of an ordinal measurement? Gender (male or female) Milligrams of a medication dosage Levels of education (associate's degree, bachelor's degree, master's degree) Score on the HESI preadmission or first year 15. A) B) C) D) Ans: 16. A) B) C) D) Ans: Which of the following is an example of an ordinal measurement? Gender (male or female) Milligrams of a medication dosage Levels of education (associate's degree, bachelor's degree, master's degree) Score on the HESI preadmission or first year examination for nursing C Feedback: Ordinal measurement ranks people on relative standing on an attribute. Levels of education signify incremental ability as related to educational degree completed. Ordinal measurement does not, however, differentiate how much greater one level is than another. Mathematical operations permissible with ordinal-level data are restricted. Gender is an example of nominal measurement. Milligrams of a medication dosage is an example of ratio measurement, as it has a meaningful zero and can provide information about the absolute magnitude of the attribute. A score on a test is an example of interval measurement, as it can rank people on an attribute and specify the distance between them, but does not have a meaningful zero. Which of the following is an example of a nominal measurement? Grams of carbohydrate intake Hand dominance (right or left ) Emotional intelligence quotients Age in years B Feedback: Hand dominance (right or left) is an example of nominal measurement. Nominal measurement involves using numbers simply to categorize attributes. Numbers in nominal measurement do not have quantitative meaning. Nominal measurement provides information only about categorical equivalence; therefore, numbers used in nominal measurement can only be treated categorically. Grams of carbohydrate intake and age in years are examples of ratio measurement, and emotional intelligence quotient is an example of interval measurement.

Nominal measurement involves using numbers simply to categorize attributes. Numbers in nominal measurement do not have quantitative meaning. Nominal measurement provides information only about categorical equivalence; therefore, numbers used in nominal measurement can only be treated categorically. Grams of carbohydrate intake and age in years are examples of ratio measurement, and emotional intelligence quotient is an example of interval measurement. 17. A) B) C) D) Ans: A) B) C) D) Ans: Which of the following is an example of a ratio measurement? Fahrenheit scale for measuring temperature Body mass index Quality of life scale score Levels of education B Feedback: Body mass index is an example of ratio measurement, as it has a meaningful zero and provides information about the absolute magnitude of an attribute (body mass). Ratio measurement is the highest level of measurement. The Fahrenheit scale for measuring temperature (interval measurement) has an arbitrary zero point. Quality of life scale is an example of interval measurement, and levels of education are an example of ordinal measurement. Which of the following is the term 18. representing the “difference between a true and obtained score''? Error of measurement An observed score Response-set bias Situational contaminant A Feedback: Quantitative data consists of two parts: a true component and an error component. Error of measurement is the difference between true and obtained score''? Error of measurement An observed score Response-set bias Situational contaminant A Feedback: Quantitative data consists of two parts: a true component and an error component. Error of measurement is the difference between true and obtained (or observed) scores. The procedures and the people themselves are susceptible to influences such as situational contaminants, response-set biases, transitory personal factors, and item sampling—all examples of factors contributing to measurement error. A) B) C) D) Ans: A) B) C) D) Ans: Which of the following most accurately 19. describes the relationship between reliability and validity? If a measure is reliable, it will be valid. As reliability increases, validity decreases. If a measure is not reliable, it cannot be valid. There is no direct relationship between the two. C Feedback: Reliability and validity are not independent qualities of an instrument. A measuring device that is unreliable cannot be valid. An instrument cannot validly measure an attribute if it is erratic and inaccurate. An instrument can be reliable without being valid. An instrument's high reliability provides no evidence of its validity, but low reliability of a measure is evidence of low validity. 20. A) B) C) D) Ans: Which of the following is indicated by the “content validity index (CVI)”? Internal consistency of the measured items within one measure The extent of expert agreement ensuring adequate content coverage Equivalence of two separate forms of a measure Criterion-related assessment B Feedback: Construct validity refers to the degree to which an instrument has an appropriate sample of items for the construct being The extent of expert agreement ensuring adequate content coverage Equivalence of two separate forms of a measure Criterion-related assessment B Feedback: Construct validity refers to the degree to which an instrument has an appropriate sample of items for the construct being measured. An instrument's content validity is based on the judgment of experts evaluating the instrument. There is no totally objective method for insuring adequate content coverage, but often a panel of subject content experts is asked to evaluate the content validity of new instruments. An instrument is internally consistent to the extent that its items measure the same trait. Equivalence, in reliability assessment, primarily concerns the degree to which two or more independent observers or coders agree about scoring on an instrument. In criterion-related validity assessments, researchers examine the relationship between scores on an instrument and an external criterion. B) C) D) Ans: 21. A) B) C) D) Ans: Which aspect of reliability does the “Cronbach's alpha'' indicate? Measurement stability performance over time Equivalence of two separate forms of a measure Internal consistency of the measure items within one measure The extent of expert agreement ensuring adequate content coverage C Feedback: An instrument is internally consistent to the extent that its items measure the same trait. Internal consistency reliability is the best way to assess an important source of measurement error in scales, the sampling of items. Internal consistency is evaluated by calculating coefficient alpha (Cronbach's alpha). The higher the coefficient, the more accurate (internally consistent) the measure. Cronbach's alpha does not indicate stability, equivalence, or content validity (extent of expert agreement ensuring adequate content coverage).

Internal consistency is evaluated by calculating coefficient alpha (Cronbach's alpha). The higher the coefficient, the more accurate (internally consistent) the measure. Cronbach's alpha does not indicate stability, equivalence, or content validity (extent of expert agreement ensuring adequate content coverage). The Beck Depression Inventory (BDI) consists of 20 items describing depressive symptoms. Subjects respond to a Likert-type scale, rating each item (0 = no symptom to 3 22. = persistent or severe symptom presence). Previous research indicates that test–retest scores of the BDI ranged from 0.60 to 0.90. Critiquing the above statements you conclude which of the following? Evidence of the stability aspect of validity of the BDI is supported Conceptual and operational definitions of depression are not consistent Evidence of the stability aspect of reliability is supported The BDI will yield high amounts of error with obtained scores C Feedback: The stability of an instrument is the degree to which similar results are obtained on separate occasions and is an aspect of reliability, not validity. Stability is assessed through test– retest reliability procedures. Researchers administer the measure to the same sample twice and then compare the scores. The test– retest results do not indicate that conceptual and operational definitions of depression are not consistent, nor do they indicate that the BDI will yield high amounts of error with obtained scores.

The test– retest results do not indicate that conceptual and operational definitions of depression are not consistent, nor do they indicate that the BDI will yield high amounts of error with obtained scores. A nurse researcher is evaluating a revised self-esteem questionnaire to determine 23. whether all of the items on the questionnaire actually effectively measure self-esteem. Which aspect of reliability is she evaluating? Equivalence Validity Stability Internal consistency D Feedback: An instrument is internally consistent to the extent that its items measure the same trait. Internal consistency reliability is the best way to assess an important source of measurement error in scales, the sampling of items. Internal consistency is evaluated by calculating coefficient alpha (Cronbach's alpha). The higher the coefficient, the more accurate (internally consistent) the measure. The purpose of a study was to determine the effectiveness of two different analgesic agents in controlling pain during menstruation in females ages 18 to 21 years. Researchers 24. administer a self-reported pain scale on days 2 and 3 of the menses. You infer that this procedure is an example of which of the following?

Researchers administer a self-reported pain scale on days 2 and 3 of the menses. You infer that this procedure is an example of which of the following? Test-retest reliability Random sampling procedures Internal validity of the study Construct validation A Feedback: The stability of an instrument is the degree to which similar results are obtained on separate occasions. Stability is assessed through test– retest reliability procedures. Researchers administer the measure to the same sample twice and then compare the scores. The selfreported pain scale administered on two different occasions is an example of test– retest reliability, not of random sampling procedures or construct validation. The internal validity of the study is not being measured. A researcher at a school of nursing decides to investigate the correlation between a preadmission HESI examination, high school GPA, and SAT scores as a predictor of success 25. in completing first year study. These admission variables will be reviewed again with grades achieved after the first year is completed. This use of data is known as which of the following? Construct validation Known-groups technique Concurrent validity Predictive validity D Feedback: Predictive validity is an instrument's ability to differentiate between people's performances on a future criterion. When a researcher correlates applicant's pre-admission test, high school grades, and SAT score with subsequent grade point averages, predictive validity is being evaluated. Construct validity is a key criterion for assessing research quality, and construct validity has most often been linked to measurement. Construct validity in measurement concerns these questions: What is this instrument really measuring? and Does it validly measure the abstract concept of interest?

Construct validity is a key criterion for assessing research quality, and construct validity has most often been linked to measurement. Construct validity in measurement concerns these questions: What is this instrument really measuring? and Does it validly measure the abstract concept of interest? One approach to construct validation is the known-groups technique. In this procedure, groups that are expected to differ on the target attribute are administered the instrument, and group scores are compared. Concurrent validity is an instrument's ability to distinguish among people who differ presently on a criterion. A group of 150 seniors with type II diabetes consented to a study examining the relationship between self-care and quality of life. Seniors received didactic classes on proper diet, exercise, stress, and medication 26. adherence with 30-minute low-impact exercise sessions once monthly for a period of 6 months. Ordinal level data collected during the study would include which of the following? Gender, ethnicity Education level, Heart Association classification Age, body mass index Scores on a self-care index B Feedback: Ordinal measurement ranks people on relative standing on an attribute. Levels of education signify incremental ability as related to educational degree completed. Heart Association classification indicates level of heart health. Gender and ethnicity are variables measured by nominal measurement. Age and body mass index would be associated with ratio measurement.

Scores on a self-care index would be examples of interval measurement. A group of nurse researchers specializing in the care of pediatric oncology patients decides to perform interviews on nurses caring for pediatric oncology patients to determine 27. patterns of nurse caring. After deciding on fifteen interview questions, they submit their draft to five pediatric oncology nurse practitioners for input. This practice illustrates obtaining which of the following? Internal consistency Content validity Face validity Equivalency B Feedback: An instrument's content validity is based on the judgment of experts evaluating the instrument, which is the case here. There is no totally objective method for insuring adequate content coverage, but often a panel of subject content experts is asked to evaluate the content validity of new instruments. Researchers can calculate a content validity index (CVI) that indicates the extent of expert agreement. Internal consistency is a measure of the extent to which all of an instrument's items measure the same thing. Equivalence, in reliability assessment, primarily concerns the degree to which two or more independent observers or coders agree about scoring on an instrument. Face validity refers to whether an instrument looks as though it is measuring the appropriate construct.

Likert scale response to questions Twenty-four-hour oral cc intake Eye color (blue, brown, hazel, green) Ability to perform activities of daily living B Feedback: Ratio measurement is the highest level of measurement. Ratio scales, unlike interval scales, have a meaningful zero and thus provide information about the absolute magnitude of the attribute. A person's twentyfour-hour oral cc intake has a meaningful zero; that is, the absolute amount of oral intake may be measured. Likert scale responses and ability to perform activities of daily living are examples of ordinal measurement, which ranks people based on relative standing on an attribute but cannot indicate the distance between them. Eye color is an example of nominal measurement, which involves using numbers simply to categorize attributes. A) B) C) D) Ans: A study's purpose was to note maternal responses to infant cues within the first 48 hours after birth. The investigator and research assistant simultaneously but 29. independently observed and scored the new mothers' behaviors while holding their infants en face. The agreement between the two raters can be described as which of the following? Content validity of the scoring instrument Internal validity of the research design Reliability of the scoring instrument External validity of the research design C Feedback: Equivalence, in reliability assessment, primarily concerns the degree to which two or more independent observers or coders agree about scoring on an instrument. If there is a high level of agreement, then the assumption is that measurement errors have been minimized. The degree of error can be assessed through interrater or interobserver reliability procedures, which involve having two or more observers or coders make independent observations. CALL 1. A) B) C) D) Ans: A) B) C) D) Ans: A) B) C) D) Ans: A parameter is a characteristic of which of the following? Population Frequency distribution Sample Normal curve A Feedback: When indexes such as averages and percentages are calculated with data from a population, they are parameters. A frequency distribution is a systematic arrangement of values from lowest to highest, together with a count or percentage of how many times each value occurred. A descriptive index from a sample is a statistic. A normal distribution (bell-shaped curve) is symmetric, unimodal, and not too peaked. If the bulk of scores on a test occurred at the 2. upper end of the distribution, the distribution could be described as which of the following? Normal Bimodal Positively skewed Negatively skewed D Feedback: A normal distribution (bell-shaped curve) is symmetric, unimodal, and not too peaked. A multimodal distribution with two peaks is bimodal. When the longer tail points to the right, the distribution has a positive skew, meaning that more people are at the lower end of the distribution. If the longer tail points to the left, the distribution has a negative skew, meaning that more people are at the upper end of the distribution.

Nominal measures Ordinal measures Interval measures Ratio measures C, D A) B) C) D) Ans: The mean is usually the statistic reported for 3. which type or types of measure? Select all that apply. Nominal measures Ordinal measures Interval measures Ratio measures C, D Feedback: The mean equals the sum of all values divided by the number of participants—what people refer to as the average. It is not meaningful to calculate the mean from nominal and ordinal measures. For interval-level measures, the mean is usually the statistic reported. 4. A) B) C) D) Ans: 5. A) B) C) D) Ans: The mode is an index of which of the following? Bivariate relationships Central tendency Risk Variability B Feedback: Indexes of “typicalness” are called measures of central tendency. The mode is the number that occurs most frequently in a distribution. Bivariate (two-variable) descriptive statistics describe relationships between two variables. Many of these indexes involve calculating changes in risk—for example, a change in risk after exposure to a potentially beneficial intervention. The most widely used variability index is the standard deviation. The measure of central tendency that is most stable is which of the following? Mode Median Mean They are all equivalent C Feedback: Of the three indexes, the mean is the most stable: if repeated samples were drawn from a population, the means would fluctuate less than the modes or medians. For interval-level or ratio-level measurements, the mean is usually the statistic reported.

For interval-level or ratio-level measurements, the mean is usually the statistic reported. The mode is the number that occurs most frequently in a distribution. The median is the point in a distribution that divides scores in half. The mean equals the sum of all values divided by the number of participants—what people refer to as the average. The measure of variability that takes into 6. account all score values is which of the following? Range Median Mean Standard deviation D Feedback: The most widely used variability index is the standard deviation. Like the mean, which is a central tendency index and not a variability index, the standard deviation is calculated based on every value in a distribution. The standard deviation summarizes the average amount of deviation of values from the mean. The median is the point in a distribution that divides scores in half. The mean equals the sum of all values divided by the number of participants—what people refer to as the average. The range is the highest score minus the lowest score in a distribution. A group of 100 students took a test. The mean was 85, the standard deviation was 5, and the 7. scores were normally distributed. About how many of the 100 scores fell between 80 and 90? 34 68 95 Impossible to determine D Feedback: A) B) C) D) Ans: was 85, the standard deviation was 5, and the 7. scores were normally distributed. About how many of the 100 scores fell between 80 and 90? 34 68 95 Impossible to determine D Feedback: The mean equals the sum of all values divided by the number of participants—what people refer to as the average. The standard deviation (SD) summarizes the average amount of deviation of values from the mean. In normal and near-normal distributions, there are roughly three SDs above and below the mean. For a normal distribution with a mean of 85 and an SD of 5, a fixed percentage of cases fall within certain distances from the mean. Sixty-eight percent of all cases fall within 1 SD above and below the mean. Thus, nearly 7 of 10 scores are between 80 and 90 or 68. 8. A) B) C) D) Ans: 9. A) B) C) D) Ans: One of the characteristics of a normal distribution is which of the following? It is bimodal 95% of the values are within two standard deviations above and below the mean The values are positively skewed The mean is 100 B Feedback: In normal and near-normal distributions, there are roughly three SDs above and below the mean. In a normal distribution, 95% of the scores fall within 2 SDs of the mean. The values are not positively or negative skewed. The distribution is not bimodal. A normal distribution (bell-shaped curve) is symmetric, unimodal, and not too peaked. A multimodal distribution with two peaks is bimodal.

A) B) C) D) Ans: A) B) C) D) Ans: Which of the following signifies the strongest relationship? r = -.64 M = .99 t = 1.44 r = .57 A Feedback: Possible values for a correlation coefficient range from –1.00 through .00 to +1.00. Note that the higher the absolute value of the coefficient (i.e., the value disregarding the sign), the stronger the relationship. A correlation of –.64, for instance, is much stronger than a correlation of +.57. A parametric test for testing the significance of differences in two group means is called a ttest. The mean (M) equals the sum of all values divided by the number of participants —what people refer to as the average. The symbol represents which of the following? An effect size A mean Total sample size An individual score B Feedback: In research articles, the mean is often symbolized as M or . Effect size index is the d statistic. Total sample size is designated as N in research reports. Individual score is written as a number. A widely used index of risk used among 11. practitioners of evidence-based practice is which of the following? The t statistic The F ratio The odds ratio Pearson's r C Feedback: The odds ratio is a widely reported risk index. A parametric test for testing the significance of differences in two group means is called a t-test. Variation between groups is contrasted with variation within groups to yield an F ratio statistic.

A parametric test for testing the significance of differences in two group means is called a t-test. Variation between groups is contrasted with variation within groups to yield an F ratio statistic. The most commonly used correlation index is Pearson's r (the product– moment correlation coefficient), which is computed with interval or ratio measures. 12. A) B) C) D) Ans: 13. A) B) C) D) Ans: The use of inferential statistics permits a researcher to do which of the following? Draw conclusions about a population based on information gathered from a sample Describe information obtained from empirical observation Interpret descriptive statistics Estimate risk and relative risk A Feedback: Descriptive statistics are useful for summarizing data, but researchers usually do more than describe. Inferential statistics, based on the laws of probability, provide a means for drawing conclusions about a population, given data from a sample. Several descriptive indexes can be used to facilitate such decision-making. Inferential statistics do not pertain to risk. The standard deviation of a sampling distribution is called which of the following? Sampling error Standard error of the mean Variance Parameter B Feedback: The standard error of the mean (SEM)—the standard deviation of this theoretical distribution—indicates the degree of average error of a sample mean.

Sample statistics fluctuate and are unequal to the parameter because of sampling error. Analysis of variance (ANOVA) is used to test mean group differences of three or more groups. Parameter estimation is used to estimate a population parameter—for example, a mean, a proportion, or a mean difference between two groups. 14. A) B) C) D) Ans: A) B) C) D) Ans: The SEM gets smaller as which of the following occurs? The mean gets smaller The sample size gets smaller The mean gets larger The sample size gets larger D Feedback: The standard error of the mean (SEM)—the standard deviation of this theoretical distribution—indicates the degree of average error of a sample mean; the smaller the SEM, the more accurate are estimates of the population value. It does not mean the mean gets smaller or larger or the sample size gets smaller. In the following statement, what would the 15. number 50 be called: 95% CI for the mean of 60 = 50 to 70? The probability value The point estimate The lower confidence limit The effect size C Feedback: With interval estimation, researchers construct a confidence interval (CI) around the estimate; the upper and lower limits are called confidence limits.

In the statement, 95% CI for the mean of 60 = 50 to 70, 50 represents the lower confidence limit and 70 is the upper confidence limit. Point estimation provides a single value of a population estimate (e.g., a mean). Interval estimation provides limits of a range of values—the confidence interval (CI)—between which the population value is expected to fall, at a specified probability. Effect size indexes (such as the d statistic) summarize the strength of the effect of an independent variable (e.g., an intervention) on an outcome variable. In the following statement, what would the 16. number 60 be called: 95% CI for the mean of 60 = 50 to 70? The probability value The point estimate The lower confidence limit The effect size B Feedback: Point estimation provides a single value of a population estimate (e.g., a mean). In this example 60 represents the mean. With interval estimation, researchers construct a confidence interval (CI) around the estimate; the upper and lower limits are called confidence limits. 95% CI for the mean of 60 = 50 to 70. 50 represent the lower confidence limit and 70 is the upper confidence limit. Effect size indexes (such as the d statistic) summarize the strength of the effect of an independent variable (e.g., an intervention) on an outcome variable. A) B) C) D) Ans: A) B) C) D) Ans: A 95% CI, in parameter estimation, 17. corresponds, in a hypothesis testing framework, to which of the following? An alpha of .95 An alpha of .05 A beta of .95 A beta of .05 B Feedback: Levels of significance are analogous to the CI values—an alpha of .05 is analogous to the 95% CI, and an alpha of .01 is analogous to the 99% CI. By convention, the minimal acceptable alpha level is .05. The probability of committing a Type II error, called beta (β), can be estimated through power analysis. Power is the ability of a statistical test to detect true relationships, and is the complement of beta (that is, power equals 1 β). The standard criterion for an acceptable risk for a Type II error is .20, and thus researchers ideally use a sample size that gives them a minimum power of .80. The steps involved in using test statistics 18. include which of the following? Select all that apply. Determining the appropriate statistic to be used Selecting a level of significance Calculating the degrees of freedom Calculating the theoretical distribution for the test statistic A, B, C Feedback: Each statistical test can be used with specific kinds of data, but the overall hypothesistesting process is similar for all tests: 1. Selecting a test statistic. 2. Specifying the level of significance. 3. Computing a test statistic. 4. Determining degrees of freedom. 5. Comparing the test statistic to a theoretical value (not calculating the theoretical distribution). C) Calculating the degrees of freedom Calculating the theoretical distribution for the test statistic A, B, C Feedback: Each statistical test can be used with specific kinds of data, but the overall hypothesistesting process is similar for all tests: 1. Selecting a test statistic. 2. Specifying the level of significance. 3. Computing a test statistic. 4. Determining degrees of freedom. 5. Comparing the test statistic to a theoretical value (not calculating the theoretical distribution). D) Ans: A) B) C) D) Ans: For which of the following levels of 19. significance is the risk of making a Type I error lowest? .10 .05 .01 .001 D Feedback: Researchers control the risk for a Type I error by selecting a level of significance, which is the probability of making a Type I error. The two most frequently used levels of significance (referred to as alpha) are .05 and .01. With a .05 significance level, we accept the risk that out of 100 samples from a population, a true null hypothesis would be wrongly rejected 5 times. In 95 out of 100 cases, however, a true null hypothesis would be correctly accepted. With a .01 significance level, the risk of a Type I error is lower: In only 1 sample out of 100 would we wrongly reject the null. By convention, the minimal acceptable alpha level is .05. Therefore the Type I error with that is lowest in this question is 0.001. 20. A) B) C) D) Ans: If the power for an analysis was .50, which of the following would be true? There would be a 50% risk of a Type II error The odds ratio would be equal to .50 The 95% CI would have a range of 50 points There would be a 50% risk of a Type I error A Feedback: The probability of committing a Type II error, called beta (β), can be estimated through 20. A) B) C) D) Ans: A) B) C) D) Ans: If the power for an analysis was .50, which of the following would be true? There would be a 50% risk of a Type II error The odds ratio would be equal to .50 The 95% CI would have a range of 50 points There would be a 50% risk of a Type I error A Feedback: The probability of committing a Type II error, called beta (β), can be estimated through power analysis. The standard criterion for an acceptable risk for a Type II error is .20, and thus researchers ideally use a sample size that gives them a minimum power of .80. Therefore a power analysis of .50 would be a 50% risk of a Type II error. The odds ratio (OR) is the ratio of two odds. With interval estimation, researchers construct a confidence interval (CI) around the estimate; the upper and lower limits are called confidence limits. By convention, researchers use either a 95% or a 99% confidence interval. Researchers control the risk for a Type I error by selecting a level of significance, which is the probability of making a Type I error. The two most frequently used levels of significance (referred to as alpha) are .05 and .01. If a researcher calculated a t-statistic to be – 2.5 and the theoretical t value (for df = 60 and 21. alpha = .05) is 2.0, the researcher would do which of the following? Conclude that a Type II error had been made Accept the null hypothesis Reject the null hypothesis Use a different level of significance C Feedback: The formula for calculating the t statistic uses group means, variability, and sample size. The computed value of t for the data is –2.5. Degrees of freedom in this example are equal to 60 and alpha of .05, the theoretical cutoff value for t with 60 degrees of freedom is 2.0. Thus, the calculated t of –2.5, which is smaller than the theoretical value of t means the null hypothesis is rejected and not accepted. The null hypothesis states that no relationship exists between variables; rejection of the null hypothesis lends support to the research hypothesis. In testing hypotheses, researchers compute a test statistic and then determine whether the B) C) D) Ans: A) B) C) D) Ans: Accept the null hypothesis Reject the null hypothesis Use a different level of significance C Feedback: The formula for calculating the t statistic uses group means, variability, and sample size. The computed value of t for the data is –2.5. Degrees of freedom in this example are equal to 60 and alpha of .05, the theoretical cutoff value for t with 60 degrees of freedom is 2.0. Thus, the calculated t of –2.5, which is smaller than the theoretical value of t means the null hypothesis is rejected and not accepted. The null hypothesis states that no relationship exists between variables; rejection of the null hypothesis lends support to the research hypothesis. In testing hypotheses, researchers compute a test statistic and then determine whether the statistic falls beyond a critical region on the relevant theoretical distribution. The value of the test statistic indicates whether the null hypothesis is “improbable.” Alpha is a measurement related to Type I errors. Beta is a measurement related to Type II errors. A different level of significance does not need to be selected. A researcher compared the mean anxiety levels of patients in a soothing music group, a massage group, or a control group.

A) B) C) D) Ans: A) B) C) D) Ans: A researcher wanted to predict whether nursing home residents would or would not experience a fall based on 10 characteristics 26. (e.g., age, presence of absence of dementia, etc.). The analysis would involve which of the following? Multiple regression ANCOVA Logistic regression MANOVA C Feedback: Logistic regression analyzes the relationships between multiple independent variables and a nominal-level outcome. In multiple regression, outcome variables are interval- or ratio-level variables. Analysis of variance (ANOVA) is used to test mean group differences of three or more groups. Multivariance analysis of variance (MANOVA) is the extension of ANOVA to more than one outcome. MANOVA is used to test the significance of differences between the means of two or more groups on two or more outcome variables, considered simultaneously. A researcher wanted to compare male and female oncology patients in terms of 27. satisfaction with nursing care, controlling for age and severity of illness. The analysis would involve which of the following? Multiple regression ANCOVA Logistic regression MANCOVA B Feedback: Analysis of covariance (ANCOVA), which combines features of ANOVA and multiple regression, is used to control confounding variables statistically—that is to “equalize" groups being compared, which is what is needed in this case. Logistic regression analyzes the relationships between multiple independent variables and a nominal-level outcome. In multiple regression, outcome variables are interval- or ratio-level variables.

Multivariance analysis of variance (MANOVA) is the extension of ANOVA to more than one outcome. MANOVA is used to test the significance of differences between the means of two or more groups on two or more outcome variables, considered simultaneously. Suppose a researcher found a multiple correlation of .40 (R = .40) between candy intake, age, income on the one hand and 28. dental caries on the other. The amount of variability that could be accounted for in dental caries by candy intake, age, and income is which of the following? 4% 16% 40% Cannot be determined B Feedback: An interesting feature of R is that, when squared, it can be interpreted as the proportion of the variability in the outcome variable that is explained by the predictors. In predicting dental caries by candy intake, age, 2 and income, if we achieved an R of .40 (R = .16), we could say that the predictors accounted for just 16%, not 4% or 40%, of the variation in dental caries by candy intake, age, and income. 29.

A) B) C) D) Ans: In analysis of covariance, a covariate is generally which of the following? An independent variable The outcome variable Either an independent or dependent variable A confounding variable D Feedback: In ANCOVA, the confounding variables being controlled are called covariates. Logistic regression analyzes the relationships between multiple independent variables, not dependent variables, and a nominal-level outcome. Which measure of central tendency is the most stable? Mode Median Mean Average C Feedback: The mean is the most stable because it fluctuates the least among these indicators. The mode is the number that comes up the most frequently. The median is the half-way cut point without considering extremes. “Average” is not used because it can refer to all central tendency indicators. B) C) D) Ans: Median Mean Average C Feedback: The mean is the most stable because it fluctuates the least among these indicators. The mode is the number that comes up the most frequently.

A Type I error A Type II error A null hypothesis Multiple regression A Feedback: The level of significance refers to the probability of rejecting a null hypothesis that is actually true, which is a Type I error. The probability of committing a Type II error— accepting a false null hypothesis—is referred to as beta (β). A null hypothesis states that there is no relationship between the independent and dependent variables. Multiple regression is used to study the strength of the relationships among more than two variables. Statistically significant means which of the following? The study findings are important. The study results are meaningful. It is unlikelihood that the results are due to chance. The hypothesis has been proven. C Feedback: The term statistically significant means that results are not likely to have been due to chance at some specified level of probability.

Statistical significance does not mean that the hypothesis is proven. A frequency distribution for height would 34. most likely be represented by which of the following? A symmetric distribution A positive skew A negative skew A normal distribution D Feedback: A normal distribution is a bell-shaped curve that is mostly symmetric, unimodal, and not very peaked. The two halves of the distribution would not be exactly equal, and thus it would not be a fully symmetric distribution. However, it would not have an off-center peak, and thus would not be a positive or negative skew. The d statistic approximates effect size by measuring the difference between the experimental group mean and the control 35. group mean, normed to the standard deviation. If the effect size is moderate, which of the following values of d would one expect to calculate? d=0 d = .20 d = .50 d = .80 C Feedback: There is a moderate effect of the independent variable when d = .50. There is no effect of the independent variable when d = 0. There is only a small effect of the independent variable when d = .20. There is a large effect of the independent variable when d = .80.

When testing multiple independent variables, the proportion of variability in the outcome 36. variable that is explained by the predictors is measured as which of the following? Paired t-test The product-moment correlation coefficient R 2 R D Feedback: 2 R , which is the square of the multiple correlation coefficient R, shows the proportion of the variability in the outcome variable that is explained by the predictors. The multiple correlation coefficient, R, shows the strength of the relationship between several independent variables and an outcome, but not direction. A bivariate correlation coefficient, such as Pearson's r (the product-moment correlation coefficient), describes the intensity and direction of a relationship between two variables. The paired t-test is a parametric test for testing the significance of differences in two group means in which the same group of subjects are tested at two different points, such as before and after an intervention. 37.

A) B) C) D) Ans: A) B) C) D) Ans: Which correlation coefficient shows the strongest relationship between two variables? –0.821 –0.653 0 0.759 A Feedback: This is the strongest relationship because the direction of the relationship is inconsequential regarding intensity. –0.821 has the largest absolute value among the answers. A correlation coefficient of 0 indicates no relationship. The correlation coefficient may range from –1.00 to 1.00. Testing the significance of difference in two 41. group means is done with which of the following? Independent groups t-test Paired t-test Dependent groups t-test Chi-squared test A Feedback: An independent groups t-test tests the significance of difference in means of two different or independent groups.

A chi-squared test measures the difference between observed frequencies and expected frequencies. To test the significance of differences between the means of two or more groups on two or 42. more outcome variables simultaneously, without controlling for covariates, one would use which of the following? Analysis of variance (ANOVA) Multivariate analysis of variance (MANOVA) Analysis of covariance (ANCOVA) Multivariate analysis of covariance (MANCOVA) B Feedback: MANOVA is used to test the significance of differences between the means of two or more groups on two or more outcome variables, considered simultaneously. ANOVA only tests for one outcome variable at a time. ANCOVA tests the significance of differences between the means of two or more groups, while controlling for one or more covariates. MANCOVA tests the significance of differences between the means of two or more groups for two or more outcome variables simultaneously, while controlling for one or more covariates. A) B) C) D) Ans: A) B) C) D) Ans: A researcher would like to test the significance of differences in the means of three age groups of baseball pitchers for the outcome variables of speed and accuracy. She 43. realizes that she will need to control for the potential confounding variable of base skill of the individual subjects in all three groups. Which type of analysis should she use? Analysis of variance (ANOVA) Multivariate analysis of variance (MANOVA) Analysis of covariance (ANCOVA) Multivariate analysis of covariance (MANCOVA) D Feedback: MANCOVA would be the best choice. MANCOVA tests the significance of differences between the means of two or more groups for two or more outcome variables simultaneously, while controlling for one or more covariates. MANOVA is used to test the significance of differences between the means of two or more groups on two or more outcome variables, considered simultaneously, but without controlling for confounding variables. ANOVA only tests for one outcome variable at a time and does not control for confounding variables. ANCOVA tests the significance of differences between the means of two or more groups on only one outcome, while controlling for one or more covariates. In an experiment testing a smoking cessation technique with two groups of smokers, one control and one experimental, what index would measure the proportion of individuals 44. in the control group who may have avoided the undesirable outcome of continued smoking had they been chosen for the experimental group? Absolute risk Absolute risk reduction Odds ratio Risk ratio B Feedback: The absolute risk reduction index measures A) B) C) D) Ans: A) B) C) D) Ans: the undesirable outcome of continued smoking had they been chosen for the experimental group? Absolute risk Absolute risk reduction Odds ratio Risk ratio B Feedback: The absolute risk reduction index measures the proportion of people in the control group who may have experienced a desirable outcome had they been treated as the subjects in the experimental group. Absolute risk is the proportion of people who experienced an undesirable outcome within each group. The odds ratio measures the proportion of subjects who experienced the undesirable outcome relative to those who experienced the desirable outcome. Risk ratio measures the estimated proportion of the original risk for the undesirable outcome that persists when subjects are exposed to the intervention. In an analysis of variance (ANOVA), which 45. of the following contrasts variation between groups with variation within groups? F ratio Post hoc tests Chi-squared statistic Pearson's r A Feedback: The F ratio contrasts these variations. Statistical analyses known as post hoc tests (or multiple comparison procedures) are used to isolate the differences between group means that are responsible for rejecting the overall ANOVA null hypothesis. The chisquared test is used to test hypotheses about the proportion of cases in different categories, as in a crosstabs. The chi-squared statistic is computed by summing differences between the observed frequencies in each cell (such as those in Table 12.10) and the expected frequencies—those that would be expected if there were no relationship between the variables.. Pearson's r is both descriptive and inferential. As a descriptive statistic, r summarizes the magnitude and direction of a relationship between two variables.

CHI 's A) B) C) D) Ans: A) B) C) D) Ans: 1. Which of the following statements is true? The results of statistical testing have direct meaning. Evaluating the credibility of a study typically involves a careful assessment of methodologic decisions. Support of a researcher's hypothesis through statistical testing offers proof of its veracity. A correlation between two variables indicates that the independent variable caused the dependent variable. B Feedback: A credibility assessment requires a careful analysis of the study's methodologic and conceptual limitations and strengths. Statistical testing results do not always have direct meaning, but often must be interpreted. Empirical evidence supporting research hypotheses never constitutes proof of their veracity. Correlation between two variables does not prove causation. Information about the precision of results 2. typically is communication in the form of which of the following? Significance levels Effect size estimates Correlation coefficients Confidence intervals D Feedback: Confidence intervals (CIs) communicate information about how precise (or imprecise) the study results are. Statistical significance indicates that the results are unlikely to be due to chance. Effect size pertains to sample size and power analysis, whereas correlation coefficients pertain to the intensity and direction of relationships between variables. A) B) C) D) Ans: A) B) C) D) Ans: Information about the magnitude or 3. importance of results typically takes the form of which of the following? Significance levels Effect size estimates Correlation coefficients Confidence intervals B Feedback: It is imperative to compute effect sizes as a means of illustrating magnitude of importance of results. Confidence intervals (CIs) communicate information about how precise (or imprecise) the study results are. Statistical significance indicates that the results are unlikely to be due to chance. Correlation coefficients pertain to the intensity and direction of relationships between variables. Which of the following is an aspect or 4. dimension of the interpretive task? Select all that apply. The accuracy or credibility of the results The meaning of the results The vigor of the results The implications of the results A, B, D Feedback: The interpretation of quantitative research results (the outcomes of the statistical analyses) typically involves consideration of: (1) the credibility of the results; (2) precision of estimates of effects; (3) magnitude of effects; (4) underlying meaning; (5) generalizability; and (6) implications for future research and nursing practice. The “vigor” of the results is not an aspect of the interpretive task. A) B) C) D) Ans: A) B) C) D) Ans: When a researcher makes a Type II error (concludes that no relationship between the independent and dependent variable exists 5. when in fact it does), this could occur because of which of the following? Select all that apply. An anomalous sample Unreliable data collection instruments Problems with adequately implementing the intervention A large sample size A, B, C Feedback: Retention of a false null hypothesis (a Type II error) can result from a variety of methodologic problems, such as poor internal validity, an anomalous sample, a weak statistical procedure, or unreliable measures. In particular, failure to reject null hypotheses is often a consequence of insufficient power, usually reflecting too small a sample size. When a researcher obtains significant results that are opposite to what was originally 6. hypothesized, it is likely that this occurred because of which of the following? Inadequate sample size Unreliable data collection instruments A flawed statistical analysis Faulty reasoning D Feedback: When significant findings are opposite to what was hypothesized, it is less likely that the methods are flawed than that the reasoning or theory is problematic. The interpretation of such findings should involve comparisons with other research, a consideration of alternate theories, and a critical scrutiny of the research methods. 7. A) B) C) D) Ans: A) B) C) D) Ans: A) B) C) The Results section of a research article summarizes results of which of the following? Study conclusions Statistical analyses Inferences Interpretation of study findings B Feedback: Study results from statistical analyses are summarized in the Results section of a research article. Researchers present their interpretations of the results in Discussion section. An inference is the act of drawing conclusions based on limited information, using logical reasoning. Conclusions may be presented in the Discussion section or in a separate section, but not in the Results section. It is important that researchers design 8. rigorous study methods to prevent which of the following? Making inferences Biases Rejection of null hypothesis Internal audit B Feedback: A researcher's job is to translate abstract constructs into plausible and meaningful proxies. Another major job concerns efforts to eliminate, reduce, or control biases through rigorous study methods. Researchers do not design rigorous study methods to prevent inferences, rejection of the null hypothesis, and the process of internal audit. A study is investigating the rate of immunization at a community-based clinic. 9. Selection bias is most likely to be present in which of the following samples? Random sample of clients accessing an urgent care clinic Random sample of records of school clinic vaccination rates Convenience sample of mothers who bring children to clinic for vaccinations A) B) C) D) Ans: A) B) C) D) Ans: A) B) C) D) Ans: A study is investigating the rate of immunization at a community-based clinic. 9. Selection bias is most likely to be present in which of the following samples? Random sample of clients accessing an urgent care clinic Random sample of records of school clinic vaccination rates Convenience sample of mothers who bring children to clinic for vaccinations Convenience sample of high school students who have received required vaccinations C Feedback: Random sampling mitigates the possibility of selection bias. A convenience sample of mothers who opt for vaccination may be a population that is significantly different from the larger population. A main purpose of the Consolidated 10. Standards of Reporting Trials (CONSORT) flow diagram is which of the following? Track the progress of study participants Present accurate statistical analyses Compare and contrast current study findings Summarize previous study findings A Feedback: Guidelines called the Consolidated Standards of Reporting Trials or CONSORT guidelines have been adopted by major medical and nursing journals to help readers track study participants. CONSORT flow charts, when available, should be scrutinized in interpreting study results. CONSORT guidelines do not address the study findings or analysis. The purpose of evaluating the evidence that 11. emanates from research articles is to do which of the following? Maintain licensure as a professional nurse Implement protocols already established in one's clinical area Improve one's clinical assessment skills Decide whether recommendations might be implemented D Feedback: Best evidence is necessary to systematically determine the possible benefit of nursing A) B) C) D) Ans: A) B) C) D) Ans: A) B) C) D) Ans: of the following? Maintain licensure as a professional nurse Implement protocols already established in one's clinical area Improve one's clinical assessment skills Decide whether recommendations might be implemented D Feedback: Best evidence is necessary to systematically determine the possible benefit of nursing treatments. Evaluation of studies is not necessary to maintain licensure, improve one's clinical assessment skills, or implement protocols that are already established. A researcher must select a sample that is representative of the population. Which of the 12. following venues would be most practical for recruitment of patients with primary hypertension? Prenatal clinic High school clinic Primary care clinic Acute care hospital C Feedback: Individuals with primary hypertension are more likely to be receiving care, and thus accessible to a researcher, in a primary care clinic than in a school clinic or prenatal clinic. Most individuals with primary hypertension are not hospitalized. A researcher plans to use a proxy variable to measure the concept of patient outcome. 13. Which of the following would be an appropriate variable to use? Length of stay in hospital Medicare eligibility Falls risk Staffing ratios A Feedback: A proxy variable is a measurable variable that stands in place of the variable of interest. The variable of interest is sometimes impractical to measure because of technical difficulty, excessive expense, ambiguity, abstraction, or multiple facets. In the case of patient outcome, the concept has too many facets to allow a practical enquiry. Length of hospital B) C) D) Ans: A) B) C) D) Ans: Medicare eligibility Falls risk Staffing ratios A Feedback: A proxy variable is a measurable variable that stands in place of the variable of interest. The variable of interest is sometimes impractical to measure because of technical difficulty, excessive expense, ambiguity, abstraction, or multiple facets. In the case of patient outcome, the concept has too many facets to allow a practical enquiry. Length of hospital stay is often chosen when rapidity of response to the pre-morbid state is the study's principal focus. Eligibility for Medicare, staffing ratios, and falls risk are not outcomes: they are, according to Donabedian's framework, structures of care Researchers conducting an exercise intervention study with overweight adults recruited a sample of 250 adults from a 14. primary care clinic. Of the 250 adults, 82 participants completed the study. The 82 participants represent what type of sample? Target population Accessible population Recruited sample Actual sample D Feedback: The actual sample consists of the original (recruited) sample minus all individuals who failed to complete the study. The target population is all individuals for whom the study findings may be directly relevant and applicable. 15. A) B) C) D) Ans: The term validity refers to which of the following?

Validity is not synonymous with honesty, though the two terms are indeed congruent. Similarly, validity is not defined as accuracy or preparation. A study reports a 60% rate of attrition among 16. the participants. This finding suggests which of the following? A threat to internal validity Lack of recruitment Appropriate compensation/incentives Invalid measurements A Feedback: The study's internal validity (the extent to which a causal inference can be made) is affected by sample composition. For example, attrition can effect sample composition and thus internal validity. Were those in the intervention group more likely (or less likely) than those in the control group to drop out of the study? If so, any observed differences in outcomes could be caused by individual differences in the groups (for example, differences in motivation), rather than by the intervention itself. This does not necessarily mean that the original sample was inadequate. Compensation and incentives may have been inadequate. High attrition is not relevant to the measurements that were used. A p-value is a measure of the likelihood that the statistical results were obtained in error. A 17. confidence interval, on the other hand, provides which of the following?

The range of the measured values in the sample reported in the research report The probability that similar results will be obtained in error, in the future The range of probable values of the variable in the population The likelihood that the results will be useful in practice C Feedback: A p-value offers information that is important, but incomplete. Confidence intervals (CIs), by contrast, communicate information about how precise (or imprecise) the study results are. CIs indicate the strength of evidence about quantities of direct interest, such as treatment benefit. The fact that research study findings are 18. statistically significant indicates which of the following? Intervention was effective Methods were valid Results were unlikely due to chance Sample size was adequate C Feedback: Statistical significance indicates that the results are unlikely to be due to chance—not that they are necessarily important or clinically effective. Statistical significance does not necessarily demonstrate that the methods were valid or the sample size was adequate or the intervention is effective.

During the conduct of a literature review While the researcher develops a conceptual framework Before the study is begun While the researcher is in the field collecting data D Feedback: Qualitative research involves an emergent design—a design that emerges in the field as the study unfolds not during the conduct of a literature review, while the researcher develops a conceptual framework, or before the study is begun. Which of the following is an issue that a 2. qualitative researcher attends to in planning a study? Select all that apply. Selecting a site Identifying needed equipment for field work Selecting research instruments Determining the maximum amount of time available for field work A, B, D Feedback: Qualitative researchers make advance decisions with regard to their research tradition, the study site, and the maximum amount of time available for the study, a broad data collection strategy, and the equipment they will need in the field. They do not select research instruments in planning a study. Which of the following design features can 3. apply to both a qualitative and quantitative study? Manipulation of the independent variable Cross-sectional versus longitudinal data collection Control over confounding variables Random assignment of study participants B Feedback: A) B) C) D) Ans: Which of the following design features can 3. apply to both a qualitative and quantitative study? Manipulation of the independent variable Cross-sectional versus longitudinal data collection Control over confounding variables Random assignment of study participants B Feedback: Qualitative research, like quantitative research, can be either cross-sectional, with one data collection point, or longitudinal, with multiple data collection points designed to observe the evolution of a phenomenon. Qualitative research is almost always nonexperimental—although a qualitative substudy may be embedded in an experiment (see Chapter 18). Qualitative researchers do not conceptualize their studies as having independent and dependent variables, and they rarely control any aspect of the people or environment under study. Blinding is rarely used by qualitative researchers. The goal is to develop a rich understanding of a phenomenon as it exists and as it is constructed by individuals within their own context. 4. A) B) C) D) Ans: Hermeneutics is closely allied with which research tradition? Ethnography Phenomenology Grounded theory Symbolic Interaction B Feedback: Interpretive phenomenology (hermeneutics) focuses on interpreting the meaning of experiences, rather than just describing them. Ethnography focuses on the culture of a group of people and relies on extensive field work that usually includes participant observation and in-depth interviews with key informants. Grounded theory researchers try to account for people's actions by focusing on the main concern that their behavior is designed to resolve. Grounded theory has its theoretical roots in symbolic interaction, which focuses on the manner in which people make sense of social interactions.

A) B) C) D) Ans: A) B) C) D) Ans: Ethnographers strive to do which of the following? Understand human cultures Develop an etic perspective Link the etic and emic perspectives into a unified whole Understand the essence of a phenomenon A Feedback: Ethnography focuses on the culture of a group of people and relies on extensive field work that usually includes participant observation and in-depth interviews with key informants. Ethnographers strive to acquire an emic (insider's) perspective of a culture rather than an etic (outsider's) perspective. Phenomenologists seek to discover the essence and meaning of a phenomenon as it is experienced by people, mainly through indepth interviews with people who have had the relevant experience. An ethnographic study of a clinic that specialized in abortion services by someone 6. from outside that culture would most likely be an example of which of the following?

An auto-ethnography A critical ethnography A microethnography A macroethnography C Feedback: Ethnographic research sometimes concerns broadly defined cultures, in what is sometimes referred to as a macroethnography. However, ethnographies sometimes focus on more narrowly defined cultures in a microethnography or focused ethnography. Ethnographers are often, but not always, “outsiders” to the culture under study. A type of ethnography that involves self-scrutiny (including scrutiny of groups or cultures to which researchers themselves belong) is called auto-ethnography or insider research. Critical ethnography focuses on raising consciousness in the hope of effecting social change. 7. A) B) C) D) Ans: A) B) C) D) Ans: Which of the following is a step in descriptive phenomenology? Select all that apply. Bracketing Inferring Analyzing Describing A, C, D Feedback: In descriptive phenomenology, which seeks to describe lived experiences, researchers strive to bracket out preconceived views and to intuit the essence of the phenomenon by remaining open to meanings attributed to it by those who have experienced it, and then to analyze and describe them. Inferring is not a step in descriptive phenomenology. A study that focused on the meaning of sacrifice among wounded military personnel 8. during war time would likely use which of the following?

A) B) C) D) Ans: Which of the following statements are true? Select all that apply. Reflexive journals can be used in the bracketing process. Hermeneutics focuses on interpreting the meaning of experiences. Descriptive phenomenology aims at understanding tacit knowledge. Interpretive phenomenologists often supplement in-depth interviews with an analysis of texts (e.g., novels, poetry). A, B, D Feedback: It is ethnography, not descriptive phenomenology, that aims at understanding tacit knowledge.

Is specified before data is collected Tends to be reductionistic Evolves during the study Involves a short period of time to collect data C Feedback: Qualitative studies use an emergent design that evolves as researchers make ongoing decisions based on what they have already learned. An emergent design in qualitative studies is a reflection of the researchers' desire to have the inquiry based on the realities and viewpoints of those under study —realities and viewpoints that are not known at the outset. It tends to be holistic, striving for an understanding of the whole, rather than reductionistic. Data collection is typically time-consuming. 20. A) B) C) D) Ans: Which of the following is characteristic of qualitative research? It is capable of adjusting to what is being learned during data collection. It depends on the robust nature of statistical analysis. It does not have to obtain Institutional Review Board approval before conducting the study. It involves survey research design. A Feedback: Quantitative researchers specify a research design before collecting even one piece of data, and rarely depart from that design once the study is underway: they design and then they do. In qualitative research, by contrast, the study design typically evolves during the project: qualitative researchers design as they do. Statistical analysis is not performed and ethics approval is necessary. Surveys are sometimes, but not always, used.

Much qualitative research is not directly generalizable. Power analysis is performed solely in quantitative research. Field notes are an integral part of qualitative research. Ethnographers seek to learn from members of a cultural group to understand their world 24. view. Ethnographic researchers refer to which of the following two perspectives? Ying and yang Emic and etic Data saturation and generalization Significant and nonsignificant B Feedback: Ethnographers seek to learn from (rather than to study) members of a cultural group—to understand their world view. Ethnographic researchers refer to “emic” and “etic” perspectives. An emic perspective refers to the way the members of the culture regard their world—the insiders' view. The emic is the local language, concepts, or means of expression that are used by the members of the group under study to name and characterize their experiences. The etic perspective, by contrast, is the outsiders' interpretation of the experiences of that culture. The other listed terms are not specific to ethnography.

Grounded theory researchers seek to understand the actions by first discovering the main concern or problem, and then the behavior that is designed to resolve it. Social processes are the major focus of this research tradition. In a qualitative study, the researcher becomes involved with the research process and must ensure that his or her own preconceived 26. beliefs and opinions do not influence the data that is emerging from the study.

The way the researcher does this is by which of the following? Bracketing Hermeneutics Narrative analysis Pentadic dramatism A Feedback: Bracketing refers to the process of identifying and holding in abeyance preconceived beliefs and opinions about the phenomenon under study. Researchers strive to bracket out presuppositions in an effort to confront their data in pure form. Narrative analysis focuses on story as the object of inquiry, to understand how individuals make sense of events in their lives. Burke's (1969) pentadic dramatism is one approach for narrative analysis. For Burke there are five key elements of a story: act, scene, agent, agency, and purpose. The term hermeneutics refers to the art and philosophy of interpreting the meaning of an object, such as a text or work of art. Ethnographers use a very specific strategy for making observations of the culture under 27. study while being involved in activities. This is referred to as which of the following? Surveys Participant observation Hermeneutics Bracketing B Feedback: Ethnographers typically use a strategy called participant observation in which they make observations of the culture under study while participating in its activities. Ethnographers observe people day after day in their natural environments to observe behavior in a wide array of circumstances.

Grounded theory tries to account for people's actions from the perspective of those involved. It seeks to discover this main 28. concern or problem and the behavior that is designed to resolve it. The manner in which people resolve this main concern is known as which of the following? Participatory action research Constant comparison The core variable A single entity C Feedback: Grounded theory researchers seek to understand the actions by first discovering the main concern or problem, and then the behavior that is designed to resolve it. The manner in which people resolve this main concern is called the core variable. A single entity is the subject of investigation in a case study. Participatory action research (PAR) is based on a recognition that the production of knowledge can be political and used to exert power. Researchers in this approach typically work with groups or communities that are vulnerable to the control or oppression of a dominant group.

A) B) C) D) Ans: The focus of case study design is which of the following? Understanding why an individual thinks or behaves in a particular manner Focusing on a story as the object of inquiry Emergence of content analysis Presentation of pentadic dramatism A Feedback: Case studies are in-depth investigations of a single entity or small number of entities. The entity may be an individual, family, institution, community, or other social unit. Case study researchers attempt to analyze and understand issues that are important to the history, development, or circumstances of the entity under study. Case studies do not prioritize the story (which is the focus of narrative analysis) and content analysis is not central to this tradition. Pentadic dramatism is associated with narrative analysis. 30. A) B) C) D) Ans: 31. A) B) C) D) Ans: A critical researcher is concerned with which of the following? Select all that apply.

Knowledge Action Empowerment Stability A, B, C Feedback: The aim of PAR is to produce not only knowledge, but action, empowerment, and consciousness-raising as well. Stability is not a goal of this research tradition. CHB A) B) C) D) Ans: A critical concern for qualitative researchers 1. in their sampling decisions is which of the following? Obtaining a sample that is representative of the population under study Accessing information-rich sources of data Recruiting a sample that can facilitate saturation quickly and efficiently Obtaining a sample with high potential for generalizability B Feedback: The aim in qualitative studies is to extract the greatest possible information from a small number of people. Quantitative research, on the other hand, is concerned with measuring attributes and identifying relationships in a population, and therefore a representative sample is desirable so that the findings can be generalized. The aim of most qualitative studies is to discover meaning and to uncover multiple realities, not to generalize to a target population. 2. A) B) C) D) Ans: Which of the following statements about sampling in qualitative research is true? Convenience sampling is considered the most appropriate method of selecting sample members. Larger samples are considered more rigorous than smaller samples. Using randomness in the sampling process is desirable. The type of sampling approach can change and evolve over the course of data collection. D Feedback: Type of sampling strategy can change over the course of a study Qualitative sampling may begin with volunteer informants and may be supplemented with new participants through snowballing. Many qualitative studies, however, evolve to a purposive (or purposeful) sampling strategy in which researchers deliberately choose the cases or types of cases that will best contribute to the study.

A) B) C) D) Ans: Theoretical sampling is most likely to be used by which of the following? Ethnographers Grounded theory researchers Phenomenologists Qualitative descriptive researchers B Feedback: Grounded theory researchers typically use theoretical sampling, in which sampling decisions are guided in an ongoing fashion by the emerging theory. Ethnographers make numerous sampling decisions, including not only whom to sample but what to sample; decision making is often aided by their key informants who serve as guides and interpreters of the culture. Phenomenologists typically work with a small sample of people who meet the criterion of having lived the experience under study. Focus groups have been used by researchers in many qualitative traditions and in qualitative descriptive research. 4. A) B) C) D) Ans: A) B) C) D) Ans: Which of the following is a type of purposive sampling? Select all that apply. Extreme case sampling Maximum variation sampling Snowball sampling Typical case sampling A, B, D Feedback: Qualitative researchers may start with convenience or snowball sampling, but usually rely on purposive sampling to guide them in selecting data sources that maximize information richness. One purposive strategy is maximum variation sampling, which entails purposely selecting cases with a wide range of variation. Another important strategy is sampling confirming and disconfirming cases —i.e., selecting cases that enrich and challenge the researchers' conceptualizations. Other types of purposive sampling include extreme case sampling (selecting the most unusual or extreme cases); typical case sampling (selecting cases that illustrate what is typical); and criterion sampling (studying cases that meet a predetermined criterion of importance). Near the end of data collection, qualitative 5. researchers may employ the technique of sampling which of the following? Criterion cases Deviant cases Typical cases Disconfirming cases D Feedback: Near the end of data collection, qualitative researchers may employ the technique of disconfirming cases.

Quantitative researchers establish eligibility criteria, but qualitative researchers do not. Extreme case sampling is a type of theoretical sampling. Focus groups would not be used in qualitative descriptive studies. A Feedback: Convenience sampling is used by both qualitative and quantitative researchers. Sampling by convenience is efficient, but is not a preferred approach, even in qualitative studies. Like quantitative researchers, qualitative researchers often identify eligibility criteria for their studies. Although they do not specify an explicit population to whom results could be generalized, they do establish the kinds of people who are eligible to participate in their research. Qualitative researchers may start with convenience or snowball sampling, but usually rely eventually on purposive sampling to guide them in selecting data sources that maximize information richness.

Samples of ten or fewer study participants 7. would be most likely to be found in which of the following? Phenomenological study Grounded theory study Ethnography Participatory action study A Feedback: Phenomenologists tend to rely on very small samples of participants—typically 10 or fewer. Grounded theory researchers typically use theoretical sampling in which sampling decisions are guided in an ongoing fashion by the emerging theory. Ethnographers make numerous sampling decisions, including not only whom to sample but what to; decision making is often aided by their key informants who serve as guides and interpreters of the culture.

In which of the following types of studies 8. would the principle of data saturation be used? Select all that apply. Grounded theory study Ethnography Phenomenological study Clinical trial A, B, C Feedback: Samples in qualitative studies that include grounded theory, ethnography, and phenomenology are typically small and based on information needs. A guiding principle is data saturation, which involves sampling to the point at which no new information is obtained and redundancy is achieved. In clinical situations, for example, it is often appropriate to let people talk freely about their problems and concerns, allowing them to take much of the initiative in directing the flow of conversation. Clinical trials would not employ the principle of data saturation. A) B) C) D) Ans: A) B) C) D) Ans: Which of the following data collection 9. approaches is conducted with a group of 5 to 10 people simultaneously? Photo elicitation interview Focused interview Critical incidents interview Focus group interview D Feedback: Focus group interviews involve groups of about 5 to 10 people whose opinions and experiences are solicited simultaneously. Photo elicitation involves an interview stimulated and guided by photographic images. Semi-structured (or focused) interviews are used when researchers have a list of topics or broad questions that must be covered in an interview. The critical incidents technique is a method of gathering information about people's behaviors in specific circumstances. Which of the following data collection 10. approaches is most likely to use a topic guide? A completely unstructured interview A focus group interview A critical incidents interview Participant observation B Feedback: In-depth interviews are the most widely used method of collecting data for qualitative studies. Self-reports in qualitative studies include completely unstructured interviews, which are conversational discussions on the topic of interest; semi-structured (or focused) interviews, using a broad topic guide; focus group interviews, which involve discussions with small groups, typically with a topic guide; and the critical incidents technique, which involves probes about the circumstances surrounding an incident that is critical to an outcome of interest.

A) B) C) D) Ans: A grand tour question is most likely to be used at which time? At the beginning of a focus group session At the end of a critical incident interview At the beginning of an unstructured interview At the end of a photo elicitation study C Feedback: In unstructured interviews, researchers begin by asking a grand tour question, such as, “What happened when you first learned that you had AIDS?” Subsequent questions are guided by initial responses. Focus group sessions and focused interviews are more likely to rely on a topic guide to prompt discussion. A photo elicitation study involves discussion that is stimulated and guided by photographic images. The critical incidents technique is a method of gathering information about people's behaviors in specific circumstances. The method focuses on a factual incident--an integral episode of human behavior; critical means that the incident must have had a discernible impact on some outcome.

Which of the following statements about data 12. collection in qualitative research is true? Select all that apply. When interviewing participants, qualitative researchers do not tend to ask their questions in any predetermined order. Unstructured observational data are often gathered in field settings through participant observation. Ethnographers usually gather their data using both observation and self-reports. The data for an unstructured interview are most likely to be in the form of field notes that the researcher records immediately after the interview has been completed. A, C, D Feedback: Qualitative researchers do not have a set of questions that must be asked in a specific order and worded in a given way. Instead, they start with general questions and allow respondents to tell their stories in a naturalistic fashion. Unstructured observational data are often gathered in field settings through participant observation. Ethnographers typically collect a wide array of data, with observation and interviews being the primary methods. Unstructured interviews are typically long, sometimes lasting several hours. Most prefer tape recording the interviews for later transcription. most likely to be in the form of field notes that the researcher records immediately after the interview has been completed.

Participant observers must maintain the same level of participation throughout the study. In a participant observation study, participants are observed but not questioned. Participant observers may use single, multiple, or mobile positioning. Participant observers most commonly record their observations by videotaping all events and transactions that they observe. C Feedback: Participant observers often use a combination of positioning approaches. Single positioning means staying in a single location for a period to observe transactions in that location. Multiple positioning involves moving around the site to observe behaviors from different locations. Mobile positioning involves following a person throughout a given activity or period. The level of participation may change during a study or stay the same. Participant observers ask questions of group members. Logs of daily events and field notes of the observer's experiences and interpretations constitute the major data collection instruments. A) B) C) D) Ans: Which of the following are types of notes 14. maintained by a participant observer? Select all that apply. Descriptive notes Participatory action notes Reflective notes Methodologic notes A, C, D Feedback: Participatory action notes are not a type of note maintained by a participant observer. The most common forms of record keeping for participant observation are logs and field notes, but photographs and videotapes may also be used. A log (or field diary) is a daily record of events and conversations. Field notes are broader and more interpretive. Field notes represent the observer's efforts to record information and to synthesize and understand the data. Field notes can be categorized according to their purpose. Descriptive notes (or observational notes) are objective descriptions of events and conversations, and the contexts in which they occurred. The goal of participant observers' descriptive notes is thick description. Reflective notes document researchers' personal experiences, reflections, and progress in the field, and can serve different purposes. Theoretical notes document interpretive efforts to attach meaning to observations. Methodologic notes are reminders about how subsequent observations should be made. Personal notes are comments about the researcher's own feelings during the research process. 15. A) B) C) D) Ans: Which of the following is characteristic of qualitative research?

Uncovering multiple realities Finding meaning in an experience Generalizing results to a target population Using non-random sampling A, B, D Feedback: Qualitative results are not normally used to generalize to a target population. Uncovering multiple realities and finding meaning are goals of qualitative research. Qualitative sampling is non-random. That is, qualitative researchers ask such sampling questions as: Who would be an information-rich data source for my study? Whom should I talk to, or what should I observe, to maximize my understanding of the phenomenon? A first step in qualitative sampling is selecting settings with high potential for information richness. Which of the following is true regarding qualitative and quantitative research? Quantitative research and qualitative research both develop eligibility criteria before consenting study participants. Quantitative research and qualitative research both use random samples whenever possible, to enhance the ability to predict within a wider population. Quantitative research and qualitative research both determine sample size in the same manner. Quantitative research and qualitative research both prefer a large sample to a small one, because it produces stronger statistical results. A Feedback: Both types of research consider what types of participants would provide the best information. Qualitative research typically involves non-random sampling. Whereas quantitative research typically requires that the sample size be determined before the study begins and remains fixed, study sample size in qualitative studies is typically not fixed and may change due to changing research needs as the study progresses. Although quantitative studies typically benefit from larger sample sizes, which tend to decrease bias, qualitative studies my benefit from smaller sample sizes depending on study Quantitative research and qualitative research both prefer a large sample to a small one, because it produces stronger statistical results.

A) B) C) D) Ans: A) B) C) D) Ans: A difficulty identified with convenience sampling is which of the following? The participants do not meet the conceptual needs of the study It is not economical It is not efficient The participants may not produce the depth of information needed D Feedback: Sampling by convenience is efficient, but is not a preferred approach, even in qualitative studies. The aim in qualitative studies is to extract the greatest possible information from a small number of people, and a convenience sample may not provide the most information-rich sources. However, convenience sample may be an economical way to begin the sampling process. Participants do meet the conceptual needs and that is why they are included. Qualitative researchers often count on 18. recruiting by referral, which is called which of the following? Convenience sampling Snowball sampling Volunteer sampling Purposive sampling B Feedback: A) B) C) D) Ans: A) B) C) D) Ans: Qualitative researchers often count on 18. recruiting by referral, which is called which of the following? Convenience sampling Snowball sampling Volunteer sampling Purposive sampling B Feedback: Snowball sampling is a method in which early participants recommend or refer additional participants. Qualitative researchers often begin with a convenience sample (also called a volunteer sample), in which they accept whatever participants happen to be available. Purposive sampling is when researchers choose participants based attributes they possess. A qualitative researcher who is attempting to provide findings from multiple diverse 19. viewpoints on a phenomenon would most likely subscribe to which of the following? Deviant case sampling Typical case sampling Criterion case sampling Confirming case sampling A Feedback: Deviant case sampling would provide multiple diverse viewpoints. Extreme (deviant) case sampling provides opportunities for learning from the most unusual and extreme informants (e.g., outstanding successes and notable failures). Typical case sampling involves the selection of participants who illustrate or highlight what is typical or average. Criterion sampling involves studying cases that meet a predetermined criterion of importance. Confirming cases are additional cases that fit researchers' conceptualizations and strengthen credibility. A) B) C) D) Ans: A) B) C) D) Ans: A qualitative researcher identifies trends in the phenomenon being studied, yet several new cases received through a snowball 20. sampling effort have divergent views of the phenomenon. These new cases are referred to as which of the following? Confirming cases Disconfirming cases Purposive cases Typical cases B Feedback: Disconfirming cases are cases that do not fit with the previous cases. Confirming cases are cases that confirm to the previous cases. Purposive (or purposeful) sampling strategy involves deliberately choosing the cases or types of cases that will best contribute to the study. Typical case sampling involves the selection of participants who illustrate or highlight what is typical or average. When developing a theory, a nurse researcher 21. uses theoretical sampling to do which of the following? To find cases that meet a predetermined criterion of importance To learn from the most unusual and extreme informants To gain new informants via referrals from other informants To choose sampling groups that will further the emerging conceptualization D Feedback: The objective of theoretical sampling is to discover categories and their properties and to offer new insights about interrelationships that occur in the substantive theory. Groups are chosen for their relevance in furthering the emerging conceptualization. These groups are not chosen before the research begins but only as they are needed for their theoretical relevance in developing emerging categories. Criterion sampling involves studying cases that meet a predetermined criterion of importance. Extreme (deviant) case sampling provides opportunities for learning from the most unusual and extreme informants (e.g., outstanding successes and notable failures).

Researchers can find no new participants that fit the criteria All the research questions are answered No new information is obtained and redundancy is achieved Participants are describing new concepts C Feedback: Sample size in qualitative research is usually determined based on informational needs. A guiding principle is data saturation—that is, sampling to the point at which no new information is obtained and redundancy is achieved. Data saturation is not achieved simply by a lack of new participants that fit the criteria or when all of the research questions are answered. Participants describing new concepts would be evidence that data saturation has not been achieved. A) B) C) D) Ans: A) B) C) D) Ans: What is the purpose of choosing key 23. informants in ethnographic research studies? Select all that apply. To facilitate recruiting more participants to the study To guide the researcher culturally To identify important events To provide a knowledgeable link to the culture B, C, D Feedback: Ethnographers may begin with a “big net” approach in sampling—that is, they mingle and converse with as many members of the culture as possible. Although they may talk to many group members (usually 25 to 50), ethnographers often rely heavily on a smaller number of key informants, who are highly knowledgeable about the culture and who develop special, ongoing relationships with the researcher. Key informants are the researcher's main link to the “inside.” Sampling in ethnography typically involves sampling things as well as people. For example, ethnographers make decisions about observing events and activities, about examining records and artifacts, and about exploring places that provide clues about the culture. Key informants can play an important role in helping ethnographers decide what to sample. Facilitating the recruitment of more participants to the study is not a purpose of choosing key informants. Which of the following are key principles that guide the selection of a sample for a 24. phenomenological study? Select all that apply. The participant must be able to articulate what it was like to have lived the experience. The participant must have considerable knowledge of the phenomenon being studied. The participant must be someone who is closely associated with someone who has experienced the phenomenon. The participant must have experienced the phenomenon being studied.

The participant must have considerable knowledge of the phenomenon being studied. The participant must be someone who is closely associated with someone who has experienced the phenomenon. The participant must have experienced the phenomenon being studied. A, D Feedback: Two principles guide the selection of a sample for a phenomenological study: (1) all participants must have experienced the phenomenon and (2) they must be able to articulate what it is like to have lived that experience. Having considerable knowledge of the phenomenon and close association with someone who has experienced the phenomenon are not key criteria. Which of the following would be the most appropriate reason to adjust the sampling 25. method in a grounded theory study as it unfolds? To better evaluate emerging conceptualizations To support past descriptions of the phenomenon To increase the availability of participants To postpone data saturation A Feedback: The goal in a grounded theory study is to select informants who can best contribute to the evolving theory. Sampling, data collection, data analysis, and theory construction occur concurrently, and so study participants are selected serially and contingently (i.e., contingent on the emerging conceptualization). The sample is adjusted in an ongoing fashion. Emerging conceptualizations help to inform the theoretical sampling process. Sampling continues until saturation is achieved— sampling methods should not be changed to postpone data saturation. Past descriptions of the phenomenon should not determine sampling methods. Availability of participants should not guide the sampling.

A priori ideas Structured questions Supplemental physiological data Self-report D Feedback: Qualitative researchers do not have a set of questions that must be asked in a specific order and worded in a given way. Instead, they start with general questions and allow respondents to tell their stories in a naturalistic fashion. Qualitative self-reports, usually obtained through interviews, tend to be conversational. Interviewers encourage respondents to define the important dimensions of a phenomenon and to elaborate on what is relevant to them, rather than relying on investigators' a priori notions of relevance. A) B) C) D) Ans: A phenomenological researcher is interviewing a participant who has lived 27. through a hurricane. Which of the following is the best example of a grand tour question appropriate to ask this participant? Why did you not evacuate the area when instructed to do so? What kind of damage did your home sustain? What was it like to live through a hurricane? How many fatalities occurred in your state due to the hurricane? C Feedback: Several approaches can be used to collect qualitative self-report data. Researchers use completely unstructured interviews when they have no preconceived view of the information to be gathered. They aim to learn about respondents' perceptions and experiences without imposing their own views. Researchers begin by asking a grand tour question such as, “What happened when you first learned that you had AIDS?” Subsequent questions are guided by initial responses. Ethnographic and phenomenological studies often rely on unstructured interviews. CHI6 A) B) C) D) Ans: A) B) C) D) Ans: The first major step that a researcher must 1. undertake in a qualitative analysis is which of the following? A search for major themes A search for appropriate metaphors The use of quasi-statistics Developing a system for organizing and indexing the data D Feedback: A first step in analyzing qualitative data is to organize and index the materials for easy retrieval, typically by coding the content of the data according to a category scheme. The actual analysis of data begins with a search for patterns and themes, which involves the discovery not only of commonalities across participants, but also of natural variation in the data. Some qualitative analysts use metaphors or figurative comparisons to evoke a visual and symbolic analogy. Another analytic step involves validation of the thematic analysis. Some researchers use quasi-statistics, a tabulation of the frequency with which certain themes or relations are supported by the data. In a final step, analysts try to weave the thematic strands together into an integrated picture of the phenomenon under investigation. Before the advent of computer software for qualitative analysis, the main procedure for 2. managing qualitative data was the development of which of the following? Conceptual files Core categories Memos Themes A Feedback: Traditionally, researchers have organized their data by developing conceptual files, which are physical files in which coded excerpts of data for specific categories are placed. Memos, themes, and core categories have not traditionally been used for management of qualitative data; rather they are current methods of analyzing qualitative data. Now, B) C) D) Ans: A) B) C) D) Ans: Core categories Memos Themes A Feedback: Traditionally, researchers have organized their data by developing conceptual files, which are physical files in which coded excerpts of data for specific categories are placed. Memos, themes, and core categories have not traditionally been used for management of qualitative data; rather they are current methods of analyzing qualitative data. Now, however, computer programs (CAQDAS) are widely used to perform basic indexing functions and to facilitate data analysis. 3. Which of the following statements is true? Narrative materials tend to be linear, which simplifies the coding process. Qualitative researchers typically develop a category scheme before they collect their data. CAQDAS is available for coding, organizing, and retrieving qualitative data. Content analysis is the analytic method used in phenomenologic studies. C Feedback: Computer assisted qualitative data analysis software (CAQDAS) can help to remove some of the work of cutting and pasting pages of narrative material. Software cannot, however, do the coding, and it cannot tell the researcher how to analyze the data.. Narrative materials usually are not linear, a fact that complicates coding. For example, paragraphs from transcribed interviews may contain elements relating to three or four different categories, embedded in a complex fashion. A preliminary category system is sometimes drafted before data collection, but more typically qualitative analysts develop category schemes based on a scrutiny of actual data. Qualitative content analysis involves analyzing the content of narrative data to identify prominent themes and patterns among the themes; this approach is not used in phenomenologic studies, which have alternate analytic methods.

Steps generally employed in the management 4. and analysis of qualitative data include which of the following? Select all that apply. Testing hypotheses Searching for recurrent themes and patterns Validating themes and patterns Developing a category scheme B, C, D Feedback: Glaser's grounded theory method is concerned with the generation of categories and hypotheses rather than testing them. A first step in analyzing qualitative data is to organize and index the materials for easy retrieval, typically by coding the content of the data according to a category scheme that is developed. The actual analysis of data begins with a search for patterns and themes and continues with the validation of these patterns and themes.. 5. A) B) C) D) Ans: 6. A) B) C) D) Ans: Quasi-statistics are essentially a method of which of the following? Statistical analysis Validation Thematic generation Constant comparison B Feedback: Validation concerns whether the themes accurately represent the perspectives of the participants. In validating and refining themes, some researchers introduce quasistatistics—a tabulation of the frequency with which certain themes or insights are supported by the data. Statistical analysis is a method used in analyzing quantitative studies. In a final step of theme generation, analysts try to weave the thematic strands together into an integrated picture of the phenomenon under investigation. Grounded theory uses the constant comparative method of data analysis, a method that involves comparing elements present in one data source (e.g., in one interview) with those in another. Spradley's method includes which type of data analysis? Select all that apply. Domain analysis Taxonomic analysis Componential analysis Statistical analysis A, B, C Feedback: One analytic approach is Spradley's method, which involves four levels of analysis: domain analysis (identifying domains, or units of cultural knowledge); taxonomic analysis (selecting key domains and constructing taxonomies); componential analysis (comparing and contrasting terms in a domain); and a theme analysis (to uncover cultural themes). Statistical analysis is a method used in analyzing quantitative studies and is not included in Spradley's method.

Validation of themes by conferring with study 7. participants was specifically considered inappropriate by whom? Colaizzi Giorgi Glaser Strauss B Feedback: Phenomenologists search for common patterns shared by particular instances. There are, however, some important differences among these approaches. Colaizzi's method, for example, is the only one that calls for a validation of results by querying study participants. Giorgi's view is that it is inappropriate either to return to participants to validate findings or to use external judges to review the analysis. The grounded theory method emerged in the 1960s in connection with research that focused on dying in hospitals by two sociologists, Glaser and Strauss. The two co-originators eventually split and developed divergent schools of thought, which have been called the “Glaserian” and “Straussian” versions of grounded theory. A) B) C) D) Ans: A) B) C) D) Ans: An alternative to Spradley's approach to 8. produce and analyze ethnographic data was developed by whom? Leininger Van Manen Colaizzi Giorgi A Feedback: Approaches to ethnographic analysis other than Spradley's have also been developed. For example, in their ethnonursing research method, Leininger and McFarland (2006) provided ethnographers with a four-phase ethno nursing data analysis guide. Van Manen, Colaizzi, and Giorgi were all phenomenologists. Phenomenologists from the Utrecht School, such as Van Manen (1997), combine characteristics of descriptive and interpretive phenomenology. Colaizzi's method is the only one that calls for a validation of results by querying study participants. Giorgi's view is that it is inappropriate either to return to participants to validate findings or to use external judges to review the analysis. Diekelmann and colleagues proposed a 7stage process of hermeneutic analysis that 9. includes the identification of which of the following? An appropriate metaphor A constitutive pattern A hermeneutic circle An exemplar B Feedback: Diekelmann's team method of hermeneutic analysis calls for the discovery of a constitutive pattern that expresses the relationships among themes. Benner's approach consists of three processes: searching for paradigm cases, thematic analysis, and analysis of exemplars. Some qualitative analysts use metaphors or figurative comparisons to evoke a visual and symbolic analogy.

Benner's approach consists of three processes: searching for paradigm cases, thematic analysis, and analysis of exemplars. Some qualitative analysts use metaphors or figurative comparisons to evoke a visual and symbolic analogy. Central to analyzing data in a hermeneutic study is the notion of the hermeneutic circle, which signifies a process in which there is continual movement between the parts and the whole of the text under analysis. 10. A) B) C) D) Ans: The process referred to as constant comparison involves which of the following? Comparing two researchers' interpretation of the data Comparing the researchers' interpretation of the data against study participants' interpretation Comparing elements present in one data source with those in another Comparing data from the study with data and categories from other similar studies C Feedback: Grounded theory uses the constant comparative method of data analysis, a method that involves comparing elements present in one data source (e.g., in one interview) with those in another, not comparing two researchers' interpretation of the data, researchers' interpretation of the data against study participants' interpretation, or data from the study with data and categories from other similar studies. A) B) C) D) Ans: A) B) C) D) Ans: In the Strauss and Corbin approach to grounded theory, the initial process of 11. breaking down, categorizing, and coding the data is often referred to as which of the following? Axial coding Core coding Open coding Selective coding C Feedback: The Strauss and Corbin grounded theory approach involves three types of coding: open (in which categories are generated), axial coding (where categories are linked with subcategories), and selective (in which the findings are integrated and refined). Substantive coding involves open coding to capture what is going on in the data, and then selective coding, in which only variables relating to a core category are coded. There is no core coding. Level III codes, in the Glaser and Strauss 12. approach to grounded theory, are which of the following? Axial codes In vivo codes Open codes Theoretical constructs D Feedback: In the Glaserian method, open codes begin with level I (in vivo) codes, which are collapsed into a higher level of abstraction in level II codes. Level II codes are then used to formulate level III codes, which are theoretical constructs. Axial coding is one of the three types of coding used in the Strauss and Corbin grounded theory method, not in the Glaser and Strauss method. A) B) C) D) Ans: Selective coding in Glaserian approach to 13. grounded theory studies begins when which of the following occurs? Constant comparison has ended Data saturation has occurred Memos have been prepared A core category has been identified D Feedback: Open coding ends when the core category is discovered, and then selective coding begins, not when data saturation has occurred or when memos have been prepared. Grounded theory uses the constant comparative method of data analysis, a method that involves comparing elements present in one data source (e.g., in one interview) with those in another. 14. A) B) C) D) Ans: Constructivist grounded theory is an approach developed by whom? Charmaz Glaser Strauss Corbin A Feedback: In Charmaz's constructivist grounded theory, coding can be word by word, line by line, or incident by incident. Initial coding leads to focused coding, which is then followed by theoretical coding. One grounded theory approach is the Glaser and Strauss (Glaserian) method, in which there are two broad types of codes: substantive codes (in which the empirical substance of the topic is conceptualized) and theoretical codes (in which the relationships among the substantive codes are conceptualized). The Strauss and Corbin (2008) approach to grounded theory analysis differs from the original Glaser and Strauss method with regard to method, processes, and outcomes. 15. A) B) C) D) Ans: 16. A) B) C) D) Ans: Which of the following is a significant challenge in qualitative analysis? Mastering the standard procedures for analyzing qualitative data Lack of narrative materials to analyze Reducing data for reporting purposes Deducing particulars from a universal C Feedback: Qualitative data analysis is challenging, for several reasons. First, the absence of standard procedures makes it difficult to explain how to do such analyses. A second challenge is that qualitative analysts must organize and make sense of hundreds or even thousands of pages of narrative materials. A third challenge is that doing qualitative analysis well requires creativity, sensitivity, and strong inductive skills (inducing universals from particulars). A good qualitative analyst must be skillful in discerning patterns and weaving them together into an integrated whole. Another challenge comes in reducing data for reporting purposes. Quantitative results can often be summarized in a few tables. Qualitative researchers, by contrast, must balance the need to be concise with the need to maintain the richness and evidentiary value of their data. Which of the following best describes the purpose of constant comparison? To identify commonalities among elements present in one data source with those in another To describe the essential nature of an experience To find patterns in the behavior and thoughts of participants To fit concepts with the incidents they are representing A Feedback: Constant comparison is a method that involves comparing elements present in one data source (e.g., in one interview) with those B) experience To find patterns in the behavior and thoughts of participants To fit concepts with the incidents they are representing A Feedback: Constant comparison is a method that involves comparing elements present in one data source (e.g., in one interview) with those in another. The process continues until the content of all sources has been compared so that commonalities are identified. To describe the essential nature of an experience is the goal of phenomenological analysis. To find patterns in the behavior and thoughts of participants is the goal of ethnographers. To fit concepts with the incidents they are representing (fit) is another element in grounded analysis theory. C) D) Ans: 17. A) B) C) D) Ans: A) B) C) D) Ans: In qualitative data analysis, which element can be used as an analytic strategy? Management Metaphors Conceptualization Constructivism B Feedback: Some qualitative researchers use metaphors as an analytic strategy. A metaphor is a symbolic comparison, using figurative language to evoke a visual analogy. Management, conceptualization and constructivism are all valid components of qualitative analysis, but none constitutes an analytic strategy. Which of the following is an activity involved 18. in qualitative content analysis? Select all that apply. Breaking down data into smaller units Coding and naming units according to the content they represent Collecting information on participants Grouping coded material based on shared concepts A, B, D Feedback: Qualitative content analysis involves breaking down data into smaller units, coding and naming the units according to the content they represent, and grouping coded material based B) content they represent Collecting information on participants Grouping coded material based on shared concepts A, B, D Feedback: Qualitative content analysis involves breaking down data into smaller units, coding and naming the units according to the content they represent, and grouping coded material based on shared concepts. Collecting information on participants is not associated with the process of content analysis. C) D) Ans: 19. A) B) C) D) Ans: Phenomenology most fundamentally involves a search for which of the following? A core category from open coding Intersubjective agreement among judges Thematic descriptions from artistic sources Common patterns shared by particular instances D Feedback: The basic outcome of all three methods of phenomenology is the description of the essential nature of an experience, often through the identification of essential themes. Phenomenologists search for common patterns shared by particular instances. Van Manen, a phenomenologist from the Utrecht School, called for gleaning thematic descriptions from artistic sources, such as literature, painting, and other art forms, claiming that they can provide rich experiential data that can increase insights into the essential meaning of the experience being studied. This, however, is not the fundamental goal of phenomenology. Discovery of a core category as a result of open coding is part of constant comparison, a method used in grounded theory research, not phenomenology. Intersubjective agreement among judges is a requirement of the method of Van Kaam, a phenomenologist of the Duquesne School; again, this is not the fundamental object of search in phenomenology. A) B) C) D) Ans: A) B) C) D) Ans: The Duquesne School of Phenomenology is 20. based on the philosophy of which of the following? Colaizzi Van Kaam Husserl Giorgi C Feedback: Three frequently used methods for descriptive phenomenology are the methods of Colaizzi (1978), Giorgi (1985), and Van Kaam (1966), all of whom are from the Duquesne School of phenomenology, based on Husserl's philosophy. Which of the following is the first stage of 21. Diekelmann, Allen, and Tanner's (1989) process of data analysis in hermeneutics? Interpretive summaries of each interview are written. A team of researchers analyzes selected transcribed interviews or texts. All the interviews or texts are read for an overall understanding. Common meanings and shared practices are identified by comparing and contrasting the text. C Feedback: Diekelmann and colleagues' stages include the following: 1. All the interviews or texts are read for an overall understanding. 2. Interpretive summaries of each interview are written. 3. A team of researchers analyzes selected transcribed interviews or texts. 4. Any disagreements on interpretation are resolved by going back to the text. 5. Common meanings and shared practices are identified by comparing and contrasting the text. 6. Relationships among themes emerge. 7. A draft of the themes along with exemplars from texts are presented to the team. Responses or suggestions are incorporated into the final draft. Common meanings and shared practices are identified by comparing and contrasting the text. C Feedback: Diekelmann and colleagues' stages include the following: 1.

A) B) C) D) Ans: A) B) C) D) What is the primary outcome of Strauss and Corbin's (2008) approach to grounded theory? A theory of how a social problem is processed A full conceptual description A central category A core category B Feedback: The outcome of the Strauss and Corbin approach is a full conceptual description. The original grounded theory method, by contrast, generates a theory that explains how a basic social problem that emerged from the data is processed in a social setting. Deciding on the central category (sometimes called the core category), which is the main category of the research, is the first step in integrating the findings in the Strauss and Corbin approach. Which of the following accurately describes a task that computer-assisted qualitative data 23. analysis software can accomplish? Select all that apply. Code interview portions and observational records Facilitate examination of relationships between codes Inform the researcher of how best to analyze the data Allow retrieval of portions of text corresponding to specified codes for analysis 23. A) B) C) D) Ans: 24. A) B) C) D) Ans: task that computer-assisted qualitative data analysis software can accomplish? Select all that apply. Code interview portions and observational records Facilitate examination of relationships between codes Inform the researcher of how best to analyze the data Allow retrieval of portions of text corresponding to specified codes for analysis B, D Feedback: Computer assisted qualitative data analysis software (CAQDAS) can help to remove some of the work of cutting and pasting pages of narrative material. Dozens of CAQDAS have been developed. These programs permit an entire data set to be entered onto the computer, each portion of an interview or observational record coded, and then portions of the text corresponding to specified codes retrieved for analysis. The software can also be used to examine relationships between codes. Software cannot, however, do the coding, and it cannot tell the researcher how to analyze the data. The primary goal of ethnography is which of the following? To identify and categorize descriptors To abstract major themes To find patterns in the behavior and thoughts of participants To collect, describe, and record data C Feedback: Analysis typically begins the moment ethnographers set foot in the field. Ethnographers are continually looking for patterns in the behavior and thoughts of participants, comparing one pattern against another, and analyzing many patterns simultaneously. Identifying and categorizing descriptors, abstracting major themes, and collecting, describing, and recording data are all phases in the ethnonursing research method, which is one approach to ethnographic analysis.

Identifying and categorizing descriptors, abstracting major themes, and collecting, describing, and recording data are all phases in the ethnonursing research method, which is one approach to ethnographic analysis. Which of the following is the final phase of 25. Leininger and McFarland's (2006) ethnonursing data analysis guide? Abstract major themes and present findings Identify and categorize descriptors Analyze data to discover repetitive patterns in their context Collect, describe, and record data A Feedback: In their ethnonursing research method, Leininger and McFarland (2006) provided ethnographers with a four-phase ethnonursing data analysis guide. In the first phase ethnographers collect, describe, and record data. The second phase involves identifying and categorizing descriptors. In phase 3, data are analyzed to discover repetitive patterns in their context. The fourth and final phase involves. Which of the following is the correct order of 26. tasks in organizing and managing narrative data for qualitative analysis? 1. Organize the data; 2. develop a category scheme; 3. read and code the data; 4. check the accuracy of transcribed data 1.

Subsequent steps, in order, include developing a category scheme, reading and coding the data, and organizing the data. 27. A) B) C) D) Ans: 28. A) B) C) D) Ans: Which of the following can best facilitate researchers' search for themes? Charting devices Detailed coding Quasi-statistics Computer software A Feedback: Researchers' search for themes, regularities, and patterns in the data can sometimes be facilitated by charting devices that enable them to summarize the evolution of behaviors, events, and processes. Detailed coding and computer software are tasks involved in data management and organization, not in the search for themes. Quasi-statistics are used to validate and refine themes, not to facilitate the search for them. Why does a researcher introduce quasistatistics? As an analytic strategy To validate and refine themes As a taxonomic analysis To provide an overall structure B Feedback: In validating and refining themes, some researchers introduce quasi-statistics—a tabulation of the frequency with which certain A) B) C) D) Ans: statistics? As an analytic strategy To validate and refine themes As a taxonomic analysis To provide an overall structure B Feedback: In validating and refining themes, some researchers introduce quasi-statistics—a tabulation of the frequency with which certain themes or insights are supported by the data. The use of quasi-statistics does not provide overall structure or taxonomic analysis and it is not an analytic strategy in and of itself. CHET 1. A) B) C) D) Ans: A) B) C) D) Ans: Which of the following terms is especially controversial among qualitative researchers? Dependability Validity Transferability Credibility B Feedback: One of several controversies regarding quality in qualitative studies involves terminology. Some argue that rigor and validity are quantitative terms that are not suitable as goals in qualitative inquiry, but others believe these terms are appropriate. Although not without critics, the criteria often viewed as the “gold standard” for qualitative research are those outlined by Lincoln and Guba (1985). These researchers suggested four criteria for developing the trustworthiness of a qualitative inquiry: credibility, dependability, confirmability, and transferability. Which of the following are terms that are considered aspects of trustworthiness within 2. the Lincoln and Guba framework? Select all that apply. Transferability Confirmability Stability Dependability A, B, D Feedback: Although not without critics, the criteria often viewed as the “gold standard” for qualitative research are those outlined by Lincoln and Guba (1985). These researchers suggested four criteria for developing the trustworthiness of a qualitative inquiry: credibility, dependability, confirmability, and transferability. Dependability refers to the stability (reliability) of data over time and over conditions. A) B) C) D) Ans: A) B) C) D) Ans: Dependability in qualitative research is 3. considered the analog of which criterion in quantitative research? Internal validity Construct validity Reliability Specificity C Feedback: Dependability refers to the stability of data over time and over conditions and is somewhat analogous to reliability, not specificity, internal validity, or construct validity, in quantitative studies. Credibility, which refers to confidence in the truth value of the findings, has been viewed as the qualitative equivalent of internal validity. The criterion that refers to neutrality or 4. objectivity in qualitative inquiry is which of the following? Credibility Transferability Authenticity Confirmability D Feedback: Confirmability refers to the objectivity of the data. Credibility, which refers to confidence in the truth value of the findings, has been viewed as the qualitative equivalent of internal validity. Transferability, the analog of external validity, is the extent to which findings can be transferred to other settings or groups. Authenticity is the extent to which researchers faithfully show a range of different realities and convey the feeling tone of lives as they are lived. A) B) C) D) Ans: A) B) C) D) Ans: Which criterion is considered analogous to 5. internal validity in the Lincoln & Guba framework? Credibility Transferability Dependability Confirmability A Feedback: Credibility, which refers to confidence in the truth value of the findings, has been viewed as the qualitative equivalent of internal validity. Dependability, the stability of data over time and over conditions, is somewhat analogous to reliability in quantitative studies. Confirmability is the qualitative equivalent of objectivity. Transferability, the analog of external validity, is the extent to which findings can be transferred to other settings or groups. If both in-depth interviews and participant observations were used to collect data on a 6. phenomenon in a study, this would be referred to as which of the following? Data triangulation Investigator triangulation Theory triangulation Method triangulation D Feedback: Triangulation is the process of using multiple referents to draw conclusions about what constitutes the truth. This includes data triangulation (using multiple data sources to validate conclusions) and method triangulation (using multiple methods to collect data about the same phenomenon). Strategies for enhancing quality during the coding and analysis of qualitative data include investigator triangulation (independent coding and analysis of some of the data by two or more researchers) and theory triangulation (use of competing theories or hypotheses in the analysis and interpretation of data).

Strategies for enhancing quality during the coding and analysis of qualitative data include investigator triangulation (independent coding and analysis of some of the data by two or more researchers) and theory triangulation (use of competing theories or hypotheses in the analysis and interpretation of data). If a researcher studying family response to adolescent suicide interviewed parents and 7. siblings independently, the triangulation approach method would be called which of the following? Data triangulation Investigator triangulation Theory triangulation Method triangulation A Feedback: Triangulation is the process of using multiple referents to draw conclusions about what constitutes the truth. This includes data triangulation (using multiple data sources to validate conclusions) and method triangulation (using multiple methods to collect data about the same phenomenon). There are three types of data triangulation: time, space, and person. Strategies for enhancing quality during the coding and analysis of qualitative data include investigator triangulation (independent coding and analysis of some of the data by two or more researchers) and theory triangulation (use of competing theories or hypotheses in the analysis and interpretation of data). 8. A) B) C) D) Ans: A) B) C) D) Ans: A member check involves the researcher reviewing data with which of the following? An external auditor A peer of the researcher A study participant A second member of the research team C Feedback: In a member check, researchers give participants feedback about emerging interpretations and then obtain participants' reactions. Other strategies for enhancing quality during the coding and analysis of qualitative data include investigator triangulation (independent coding and analysis of some of the data by two or more researchers); external validation through peer debriefings (exposing the inquiry to the searching questions of peers); and launching an inquiry audit (a formal scrutiny of audit trail documents by an independent auditor). The maintenance of good, thorough 9. documentation and a decision trail is especially critical in which of the following? Member checks Stepwise replications Negative case analysis Inquiry audits D Feedback: Strategies for enhancing quality during the coding and analysis of qualitative data include launching an inquiry audit (a formal scrutiny of audit trail documents by an independent auditor); stepwise replication (dividing the research team into two groups that conduct independent inquiries that can be compared and merged); and searching for rival explanations and undertaking a negative case analysis (revising interpretations to account for cases that appear to disconfirm early conclusions). Strategies for enhancing quality during qualitative data collection include member checks (asking study participants to review and react to study data and emerging conceptualizations).

Strategies for enhancing quality during qualitative data collection include member checks (asking study participants to review and react to study data and emerging conceptualizations). A quality-enhancement strategy about which 10. there is considerable controversy is which of the following? Member checks Stepwise replications Negative case analysis Inquiry audits A Feedback: Few strategies for enhancing data quality are as controversial as member checking. Nevertheless, it is a strategy that has the potential to enhance credibility if it is done in a manner that encourages candor and critical appraisal by participants.

The term A) B) C) D) Ans: Generalizability Validity Reliability Correlation B, C Feedback: Lincoln and Guba (1985) created standards for the trustworthiness of qualitative research that parallel the standards of reliability and validity in quantitative research. The term generalizability, used in quantitative research, is analogous to the term transferability in qualitative research, which is the extent to which qualitative findings can be transferred to or have applicability in other settings or groups. A correlation is the association or relationship between variables. 12. A) B) C) D) Ans: 13. A) B) C) D) Ans: Which of the following is characteristic of qualitative research? Select all that apply. It is consistent with the constructivist paradigm of inquiry. It generates causal hypotheses. It tests hypotheses. It involves an iterative process of interpretation and analysis. A, B, D Feedback: Interpretation in qualitative studies sometimes yields hypotheses that can be tested in more controlled quantitative studies. Qualitative studies are well suited to generating causal hypotheses, but not to testing them. In the constructivist paradigm, multiple interpretations of reality exist. The goal of research conducted according to the constructivist paradigm is to understand how individuals construct their own reality. This paradigm is often associated with qualitative research. Interpretation and analysis of qualitative data occur simultaneously, in an iterative process. Credibility in qualitative research refers to which of the following? The reliability of data over time Objectivity of the interpretation of the data Applicability of the data to other groups Confidence in the truth value of the data D Feedback: Credibility or the believability of data refers 13.

The reliability of data over time Objectivity of the interpretation of the data Applicability of the data to other groups Confidence in the truth value of the data D Feedback: Credibility or the believability of data refers to confidence in the truth value of the data and data interpretation. Dependability is the reliability of data over time. Confirmability refers to establishing that the data objectively represent the participants' information and view point, and not that of the researcher. Transferability is the extent to which qualitative findings can be transferred to or have applicability in other settings or groups. Confirmability in qualitative research refers to which of the following? The reliability of data over time Objectivity of the interpretation of the data Applicability of the data to other groups Confidence in the truth value of the data B Feedback: Confirmability refers to objectivity, achieved through congruence or agreement between two or more independent evaluators about the data's accuracy, relevance, or meaning. Dependability refers to the stability of data over time. Transferability refers to the applicability of data to other groups. Credibility refers to the believability or confidence in the truth of the findings. The term transferability in qualitative 15. research is similar to which term used in quantitative research?

Peer debriefings in qualitative research provide proof that interpretations are correct. Qualitative research attempts to test hypotheses generated from quantitative research. Interpretation and analysis of qualitative data typically occur simultaneously. Qualitative research methods are best suited to study well-known phenomenon. C Feedback: Interpretation and analysis of qualitative data typically occur virtually simultaneously, in an iterative process. Interpretation in qualitative studies sometimes yields hypotheses that can be tested in more controlled quantitative studies. The nature of qualitative research is to generate, not test hypotheses. Qualitative research is especially productive when it is used to describe and explain poorly understood phenomena. Prudent qualitative researchers hold their interpretations up for closer scrutiny—self-scrutiny as well as review by peers and outside reviewers. Even when researchers have undertaken peer debriefings and other strategies described in this chapter, these procedures do not constitute proof that interpretations are correct.

A) B) C) D) Ans: Which of the following statements about controversies in qualitative research is true? Unlike quantitative research methods, qualitative research methods do not require rigorous study designs. There is lack of consensus regarding the quality criteria for qualitative inquiry. There is no “gold standard” in qualitative research criteria. There is no comparable criterion in qualitative research for the positivists' criterion of internal validity. B Feedback: Establishing a consensus on what the quality criteria for qualitative inquiry should be, and what they should be named, remains elusive, and it is unlikely that a consensus will be achieved in the near future, if ever. Guba and Lincoln established criteria considered as the “gold standard” for qualitative research; however, not all qualitative researchers agree with their recommendations. The criteria established by Guba and Lincoln to develop trustworthiness of qualitative inquiry— credibility, dependability, confirmability, and transferability—represent parallels to the positivists' criteria of internal validity, reliability, objectivity, and external validity, respectively.

Which of the following is a barrier that 18. qualitative researchers face in demonstrating the trustworthiness of their studies to readers? Page limitations imposed by journals Reflexivity Lack of generalizability Small sample sizes A Feedback: Adhering to page constraints imposed by journals inevitably reduces the amount of thick description and verbatim accounts that can be reported in qualitative research reports. Page limitations imposed by journals ultimately impact the ability of the researcher to support the authenticity of the study with thick description of the content, and researchers must compromise in how the data is reported. Reflexivity involves awareness that the researcher as an individual brings to the inquiry a unique background, set of values, and a social and professional identity that can affect the research process; this would not be a barrier to demonstrating trustworthiness. Generalizability and large sample size, although important in quantitative research, are not goals of qualitative research because qualitative research is context-bound.

A nurse-midwife conducted a phenomenology study of the lived experience of women in Haiti who gave birth following the 2010 19. Haitian earthquake. She collected data from 15 women over a 12-month period of time. Which quality-enhancement strategy is described in this example? Persistent observation Prolonged engagement Reflexivity Data triangulation B Feedback: Prolonged engagement is the investment of a sufficient amount of time to collect data about a study population to achieve an in-depth understanding of the phenomenon. In this example the researcher spent 12 months interacting with study participants to explore the lived experience of the women. Persistent observation refers to the collection of specific data relevant to the phenomenon under investigation. Reflexivity refers to the awareness and personal experience and insight that the researcher brings to the study. Data triangulation refers to the use of multiple sources to draw conclusions about what constitutes truth in the data.

Persistent observation refers to the collection of specific data relevant to the phenomenon under investigation. Reflexivity refers to the awareness and personal experience and insight that the researcher brings to the study. Data triangulation refers to the use of multiple sources to draw conclusions about what constitutes truth in the data. A nurse working in an adolescent health clinic conducted a grounded theory study related to contraceptive decision-making in Latina 20. youth. She collected data from individual interviews and focus groups. Which of the following quality-enhancement strategies is described in this example? Persistent observation Prolonged engagement Reflexivity Data triangulation D Feedback: Data triangulation refers to the use of multiple data sources for the purpose of validating conclusions. In this example the nurse collected data from individual interviews and focus groups. Persistent observation refers to the collection of specific data relevant to the phenomenon under investigation.

A) B) C) D) Ans: A) B) C) D) Ans: A nurse working in an inner-city clinic conducted an ethnographic study of sex workers to gain understanding of factors related to HIV risk for these women. After she 21. completed her data collection, she gave three participants feedback about her findings for their review and commentary. Which of the following quality-enhancement strategies is described in this example? Audit trail Data triangulation Reflexivity Member checking D Feedback: In member checking, researchers give participants feedback about emerging interpretations and then obtain participants' reactions to those interpretations. This method allows participants to validate whether or not the researchers' interpretations accurately represent their realities. An audit trail is a systematic collection of materials and documentation that would allow an independent auditor to draw conclusions about the data. Data triangulation refers to the use of multiple sources to draw conclusions about what constitutes truth in the data. Reflexivity refers to the awareness and personal experience and insight that the researcher brings to the study. Which of the following quality-enhancement 22. strategies has the greatest potential for leading to erroneous conclusions about the data?

An audit trail is a systematic collection of materials and documentation that would allow an independent auditor to draw conclusions about the researcher's interpretation of the data and is a good tool for enhancing the trustworthiness of data. Reflexivity refers to the awareness and personal experience and insight that the researcher brings to the study. Data triangulation refers to the use of multiple sources to draw conclusions about what constitutes truth in the data. In qualitative research, investigator 23. triangulation is comparable to which quantitative research concept? Content validity Construct validity Inter-rater reliability Internal consistency C Feedback: Investigator triangulation is conceptually analogous to inter-rater reliability in quantitative studies. Content validity is a term used in quantitative research that refers to the degree to which items in an instrument actually measure the intended concept. Construct validity in quantitative research refers to the validity of inferences gleaned from the study setting or an instrument used in the study in measuring the construct under investigation. Internal consistency in quantitative research refers to the degree to which sub-parts of a scale or instrument measure the same attribute or dimension. A) B) C) D) Ans: The proper rationale for searching for and 24. including disconfirming evidence is which of the following? To eliminate confounding cases from data analysis To refine a hypothesis or theory To confirm saturation of the data To formulate a conclusion based on existing data B Feedback: Searching for disconfirming evidence is a verification procedure that challenges an explanation or category that has emerged early in data analysis. It occurs concurrently with data collection and analysis. Negative case analysis is a procedure to continuously refine a hypothesis or theory until it accounts for all cases. Saturation of data occurs when data collection yields redundant information. Triangulation is the process of using multiple referents to draw conclusions about what constitutes the truth. Eliminating confounding cases would be the opposite of including disconfirming evidence. 25. A) B) C) D) Ans: Which of the following is true of thick description in qualitative research? It should not include verbatim quotes from participants. It should not include information that can be interpreted as controversial. It should be implicit in the description of the research context. It should avoid emotional impact. C Feedback: Thick description refers to a rich, thorough, and vivid description of the research context, the people who participated in the study, and the experiences and processes observed during the inquiry. Thick description includes the free use of verbatim quotes from study participants and contributes to the authenticity of a qualitative study. According to Sandelowski, thick description should be implicit in the description of the research context and the term itself should not be C) D) Ans: It should be implicit in the description of the research context. It should avoid emotional impact. C Feedback: Thick description refers to a rich, thorough, and vivid description of the research context, the people who participated in the study, and the experiences and processes observed during the inquiry. Thick description includes the free use of verbatim quotes from study participants and contributes to the authenticity of a qualitative study. According to Sandelowski, thick description should be implicit in the description of the research context and the term itself should not be written in the research report. In high-quality qualitative studies, descriptions typically need to go beyond a faithful rendering of information. Powerful description is evocative and has the capacity for emotional impact. Qualitative researchers should, however, avoid misrepresenting their findings by sharing only the most dramatic or sensational stories. CH 18 A) B) C) D) Ans: A) B) C) D) Ans: The use of both of qualitative and quantitative 1. data in a study or cluster of studies serves the important purpose of which of the following? Providing researchers with different skills an opportunity to collaborate Enhancing the study's validity Allowing participants to select an unstructured or structured method of responding Enhancing the likelihood that the study will be published B Feedback: Enhanced validity is an advantage of mixed methods research. When a hypothesis or model is supported by multiple and complementary types of data, researchers can be more confident about their inferences. The mixed methods approach does not necessarily increase the likelihood that the study will be published. It does not allow participants to select their method of responding, although it can involve intramethod mixing (for example, use of structured and unstructured selfreports). Providing researchers with different skills an opportunity to collaborate is not an important rationale for this approach. The integration of qualitative and quantitative 2. approaches in a single study constitutes a form of which of the following? Hypothesis testing Theory generation Triangulation Methodologic research C Feedback: Triangulation of methods can provide opportunities for testing alternative interpretations of the data, and for examining the extent to which the context helped to shape the results.

An arrow is used for sequential designs, and a “+” is used for concurrent designs. Parentheses show an embedded structure. QUAL + QUAN, for example, is a concurrent design (only one phase) in which neither strand is dominant; QUAN(qual) shows a qualitative strand embedded in a quantitative study. The phase of a clinical trial that typically uses 5. a full experimental design is which of the following? Phase I Phase II Phase III Phase IV C Feedback: Clinical trials, which are studies designed to assess the effectiveness of clinical interventions, often involve a series of phases. Phase I is designed to finalize features of the intervention. Phase II involves seeking preliminary evidence of efficacy and opportunities for refinements.

If a researcher wanted to assess how well an evidence-based protocol for encouraging 7. adolescent mothers to breastfeed was meeting its objectives, the research would be which of the following? Survey Evaluation Methodologic research Secondary analysis B Feedback: Evaluation research assesses the effectiveness of a program, policy, or procedure to assist decision-makers in choosing a course of action. Evaluations can answer a variety of questions. Survey research examines people's characteristics, behaviors, intentions, and opinions by asking them to answer questions. In methodologic research, the investigator is concerned with the development, validation, and assessment of methodologic tools or strategies. Secondary analysis refers to studies in which researchers analyze previously collected data—either quantitative or qualitative.

An impact analysis An economic analysis A process analysis A secondary analysis A Feedback: Impact analyses, analogous to Phase III clinical trials, use an experimental or strong quasi-experimental design because the aim is to make a causal inference about the benefits of a special program. Impact analyses test whether an intervention caused any net impacts relative to the counterfactual. Economic (cost) analyses seek to determine whether the monetary costs of a program are outweighed by benefits. Process analyses describe the process by which a program gets implemented and how it functions in practice.

A question that is exploratory would indicate a qualitative approach. A question that confirms or examines causal effects would indicate a quantitative approach. Questions that are exploratory and examine causal effects would indicate a mixed methods approach. Which of the following is most likely the 18. strongest argument for mixed method research? Pragmatism Incrementality Enhanced validity Complementarity A Feedback: Perhaps the strongest argument for MM research is that some questions require mixed methods. Pragmatism, a paradigm often associated with MM research, provides a basis for a position that has been stated as the “dictatorship of the research question” (Tashakkori & Teddlie, 2003, p. 21). Pragmatist researchers consider that it is the research question that should drive the inquiry, and its design and methods. They reject a forced choice between the traditional postpositivists' and constructivists' modes of inquiry. Sequencing and prioritization are important when reporting research. Which of the 19. following is the correct notation for a convergent parallel design study?. QUAL + QUAN QUAL → QUAN QUAL(quan) QUAN → qual A Feedback: The purpose of a convergent parallel design (also called a triangulation design) is to obtain different, but complementary, data about the central phenomenon under study. The goal of this design is to converge on “the B) C) D) Ans: A) B) C) D) QUAL → QUAN QUAL(quan) QUAN → qual A Feedback: The purpose of a convergent parallel design (also called a triangulation design) is to obtain different, but complementary, data about the central phenomenon under study. The goal of this design is to converge on “the truth” about a problem or phenomenon by allowing the limitations of one approach to be offset by the strengths of the other. In this design, qualitative and quantitative data are collected simultaneously, with equal priority (QUAL + QUAN). In an embedded design, one type of data is used in a supportive capacity in a study based primarily on the other data type. Either qualitative or quantitative data can be dominant—although qual is often supportive of QUAN in embedded designs. Sequencing is often concurrent. The notation for embedded designs uses parentheses: QUAL(quan) or QUAN(qual). Explanatory designs are sequential designs with quantitative data collected in the first phase, followed by qualitative data collected in the second phase. In explanatory designs, the quantitative strand has priority—that is the design notation is QUAN → qual . Exploratory designs are also sequential MM designs, but qualitative data are collected first. The design has as its central premise the need for initial in-depth exploration of a concept. Usually the first phase focuses on detailed exploration of a poorly understood phenomenon, and the second phase is focused on measuring it or classifying it. In an exploratory design, the qualitative phase is typically dominant (QUAL → quan), although in many studies the two strands have equal priority (QUAL → QUAN). Nested sampling is a preferred sampling 20. technique used by many researchers for which of the following reasons? It reduces costs related to recruiting participants. It decreases the risk for bias. Using overlapping samples can be advantageous. Only one group of people has to be recruited for both qualitative and quantitative strands.

It reduces costs related to recruiting participants. It decreases the risk for bias. Using overlapping samples can be advantageous. Only one group of people has to be recruited for both qualitative and quantitative strands. C Feedback: A unique sampling issue in MM studies concerns whether the same people will be in both the qualitative and quantitative strands. The best strategy depends on the study purpose and the research design, but using overlapping samples can be advantageous. Indeed, a particularly popular strategy is a nested approach in which a subset of participants from the quantitative strand is used in the qualitative strand. Nested sampling does not necessarily reduce costs or risk for bias. Moreover, only a subset of participants from the quantitative strand are used in the qualitative strand, so two groups of people are still needed. Evaluation research looks at the effectiveness of a program, policy, or procedure to impact 21. decision-making. Which of the following lists the three analysis components of an evaluation? Process, Impact, and Outcome analyses Structure, Impact, and Outcome analyses Impact, Process, and Economic analyses Process, Efficacy, and Economic analyses C Feedback: Evaluation provides the researcher with the answer to the questions posed in the question. It effectively evaluates the program through impact, process, and economic analyses. Which of the following most accurately 22. describes the triangulation design in mixed methods research?

Assess a clinical intervention Describe program implementation Identify a net impact Weigh a program's benefits against its monetary costs B Feedback: A process analysis is often undertaken to obtain descriptive information about the process by which a program gets implemented and how it actually functions. In an impact analysis component of an evaluation, researchers seek to identify the program's net impacts, that is, impacts that can be attributed to the program, over and above the effects of usual care. Program evaluations may also include an economic (or cost) analysis to assess whether the program's benefits outweigh its monetary costs. Clinical trials are designed to assess clinical interventions. 24. A) B) C) D) Ans: Which of the following statements most accurately describes methodologic research?

Evidence-based practice Evidence hierarchies Meta-analyses Primary studies A Feedback: Systematic reviews, a cornerstone of evidence-based practice (EBP), are inquiries that follow many of the same rules as those for primary studies, i.e., original research investigations. Evidence-based practice relies on rigorous integration of research evidence on a topic through systematic reviews of quantitative findings and metasyntheses of qualitative findings. Meta-analyses of randomized controlled trials (RCTs) are at the pinnacle of traditional evidence hierarchies. The unit of analysis in a meta-analysis is which of the following? Individual study participants A primary qualitative study A primary quantitative study Prior systematic reviews C Feedback: The unit of analysis in a meta-analysis is a primary quantitative study, whereas the unit of analysis in a meta-synthesis is a primary qualitative study. The unit of analysis in a primary study is an individual study participant. Prior systematic reviews are not the unit of analysis in a meta-analysis.

Which of the following activities are normally 4. undertaken as part of doing a meta-analysis? Select all that apply. Obtaining the original data set from primary study researchers Selecting a sample of studies Systematically extracting and recording data Evaluating the quality of studies B, C, D Feedback: Systematic reviews often involve statistical integration of findings through meta-analysis, a procedure whose advantages include objectivity and enhanced power. The steps in both quantitative and qualitative integration are similar and involve the following: formulating the problem, designing the study (including establishing sampling criteria), searching the literature for a sample of primary studies but not obtaining the original data set from primary study researchers, evaluating study quality, extracting and encoding data for analysis, analyzing the data, and reporting the findings.

Select all that apply. Counteract the effect of biases against the null hypothesis Increase sample size and therefore have a more comprehensive evidence base Minimize the risk of publication bias Include only published, peer-reviewed studies A, B, C Feedback: There is no consensus on whether integrations should include the grey literature—i.e., unpublished reports; in quantitative studies, a concern is that there is a bias against the null hypothesis, a publication bias stemming from the underrepresentation of nonsignificant findings in the published reports. On the other hand, some people avoid the grey literature and restrict their sample to reports in peerreviewed journals, arguing that the peer review system is an important, tried-and-true screen for findings worthy of consideration as evidence. A viable approach to addressing the quality of 6. primary studies included in a meta-analysis is which of the following? Ignoring the problem of quality by using all studies regardless of rigor Doing sensitivity analyses to assess if the effects change when low-quality studies are included. Using a random effects model rather than a fixed effects model. Using a forest plot to assess the degree to which study quality is related to effect size. B Feedback: Quality assessments (which may involve formal quantitative ratings of methodologic rigor) are sometimes used to exclude weak studies from reviews, but they can also be used to differentially weight studies or in sensitivity analyses to determine if including or excluding weaker studies changes conclusions.

When heterogeneity of effects is high 7. (statistically significant), the preferred metaanalytic approach is which of the following? Abandon efforts to undertake a meta-analysis Use a fixed effects analytic model Use a random effects analytic model Use a forest plot to display the extensiveness of heterogeneity to readers of the report C Feedback: Statistical heterogeneity (diversity in effects across studies) is a major issue in metaanalysis, and affects decisions about using a fixed effects model (which assumes a single true effect size) or a random effects model (which assumes a distribution of effects). Heterogeneity can be examined using a forest plot. An effect size index that can be used in meta8. analyses includes which of the following? Select all that apply. Standardized mean difference or d Intensity effect size Pearson's correlation coefficient (r) The odds ratio (OR) A, C, D Feedback: An intensity effect size is commonly used in metasyntheses, not meta-analyses, and indicates the concentration of findings within each report. Meta-analyses depend on the calculation of an index that encapsulates in a single number the relationship between the independent and outcome variable in each study. Cohen's d, the effect size index most often used, transforms all effects into standard deviation units (Chapter 12).

Cohen's d, the effect size index most often used, transforms all effects into standard deviation units (Chapter 12). When the outcomes in the primary studies are dichotomies, meta-analysts have a choice of effect index, including the odds ratio (OR) and risk ratio (RR). In nonexperimental studies, a common effect size statistic is Pearson's r, which indicates the magnitude and direction of effect. A forest plot portrays information about 9. which of the following for each study in the meta-analysis? 95% CIs around an effect size Number of study participants Quality assessment scores Sample size and standard errors A Feedback: A forest plot graphs the effect size for each study, together with the 95% CI around each estimate, not the number of study participants, quality assessment scores, or sample size and standard errors. 10. A) B) C) D) Ans: Which of the following best defines metasyntheses? Involve interpretation as well as integration Involve meta-summaries Exclude studies judged to be low on trustworthiness Rely primarily on phenomenological primary studies A Feedback: Metasyntheses are more than just summaries of prior qualitative findings (i.e., integration); they involve a discovery of essential features of a body of findings and a transformation Exclude studies judged to be low on trustworthiness Rely primarily on phenomenological primary studies A Feedback: Metasyntheses are more than just summaries of prior qualitative findings (i.e., integration); they involve a discovery of essential features of a body of findings and a transformation that yields new interpretations. Metasyntheses can build upon meta-summaries, but require findings that are more interpretive, i.e., from reports that are characterized as syntheses. A researcher may decide to exclude studies in which the reported findings are not adequately supported with direct quotes from participants. In a meta-analysis systematic review, the sample consists of the primary studies that have addressed the research question, not necessarily phenomenological primary studies. C) D) Ans: 11. A) B) C) D) Ans: A) B) C) D) Ans: A widely-used approach to metasynthesis was developed by whom? Polit and Beck Noblit and Hare Glaser and Strauss Sackett and Cochrane B Feedback: Noblit and Hare (1988), not Glaser and Strauss or Sackett and Cochrane, whose approach to integration is called metaethnography, argued that integration should be interpretive and not aggregative—i.e., that the synthesis should focus on constructing interpretations rather than descriptions. Polit and Beck are the authors of the textbook. Paterson and colleagues developed an approach to metasynthesis that includes which 12. of the following components? Select all that apply.

An individual study A study participant A mean value A theme or qualitative finding D Feedback: Studies are called summaries if they yield descriptive synopses of the qualitative data, usually with lists and frequencies of themes, without any conceptual reframing, not an individual study, a study participant, or mean value. 14. A) B) C) D) Ans: of the following components? Select all that apply. Meta-data analysis Meta-method Meta-ethnography Meta-theory A, B, D Feedback: The method developed by Paterson and a team of Canadian colleagues (2001) involves three components: meta-data analysis, metamethod, and meta-theory, not metaethnography. Meta-ethnography is Noblit and Hare's approach to integration. Which of the following is a cornerstone of evidence-based practice? Systematic reviews Secondary study reports Meta-analysis of qualitative studies Narrative integration A Feedback: Systematic reviews, a cornerstone of evidence-based practice (EBP), are inquiries that follow many of the same rules as those for primary studies, i.e., original research investigations. Secondary study reports are not the basis of evidence-based practice; primary studies, such as journal articles, are the basis.

Meta-analysis differs from meta-synthesis in 15. that meta-analysis studies use which of the following? Select all that apply. Objectivity in drawing conclusions regarding a body of evidence Combining phenomena into a transformed whole Subjective decisions about how much weight to give findings from different studies A measure of the probability of detecting a true relationship between variables A, D Feedback: Meta-analysis offers a simple advantage as an integration method: objectivity. It is difficult to draw objective conclusions about a body of evidence using narrative methods when results are disparate, as they often are. Narrative reviewers make subjective decisions about how much weight to give findings from different studies, and so different reviewers may reach different conclusions about the evidence in reviewing the same studies. Meta-analysts also make decisions, but the decisions are explicit and open to scrutiny. Another advantage of metaanalysis concerns power, i.e., the probability of detecting a true relationship between variables (Chapter 12).

Which of the following not only yields information about the existence of a 16. relationship between variables in many studies but also an estimate of its magnitude? Effect size Problem formulation Grey literature Subgroup analysis A Feedback: Effect sizes are averaged across studies, yielding information about not only the existence of a relationship between variables in many studies, but an estimate of its magnitude. Problem formulation is the first step in both meta-analysis and metasynthesis studies and involves establishing the research question. Grey literature consists of studies with a more limited distribution, such as dissertations, unpublished reports, and so on. One strategy for exploring moderating effects on effect size is to do subgroup analyses, which involve splitting effect size information into distinct categorical groups—for example, men and women.

It is appropriate to use statistical integration 17. when which of the following components are nearly identical across studies? Independent variable, dependent variable, and study populations Statistical methods, population sample, hypotheses Dependent variable, research design, theory explication Available evidence, novel interpretation of findings, population sample A Feedback: Reviewers need to decide whether it is appropriate to use statistical integration. One basic criterion is that the research question being addressed should be nearly identical across studies. This means that the independent and dependent variables, and the study populations, are sufficiently similar to merit integration. Which of the following is a condition under 18. which meta-analysis would be inappropriate to conduct? Highly conflicting results among studies Research questions across studies being nearly identical A large number of studies to draw from Independent variables are similar across studies A) B) C) D) Ans: A) B) C) D) Ans: Which of the following is a condition under 18. which meta-analysis would be inappropriate to conduct?

One basic criterion is that the research question being addressed should be nearly identical across studies. This means that the independent and dependent variables, and the study populations, are sufficiently similar to merit integration. A second criterion concerns whether there is a sufficient base of knowledge for statistical integration. If there are only a few studies, or if all of the studies are weakly designed and harbor extensive bias, it usually would not make sense to compute an “average” effect. One final issue concerns the consistency of the evidence. When the same hypothesis has been tested in multiple studies and the results are highly conflicting, meta-analysis is likely not appropriate. Which of the following is most accurate 19. regarding researchers conducting metasyntheses? They often conduct original studies on the same topic as the metasynthesis they are conducting. They perform little advance planning, as it is not needed in qualitative research. They make sampling decisions at the end of the study. They use only peer-reviewed journals in the analysis. A Feedback: Meta-analyses often are undertaken by researchers who did not do one of the primary studies in the review. Metasyntheses, by contrast, are often done by researchers whose area of interest has led them to do both original studies and metasyntheses on the same topic.

Like a quantitative systematic review, a metasynthesis requires considerable advance planning. Also like meta-analysts, metasynthesists must also make upfront sampling decisions. For example, they face the same issue of opting to include only findings from peer-reviewed journals in the analysis.

An example of this calculation is which of the following? Inclusion criteria Forest plot Cohen's d Moderator analyses C Feedback: Cohen's d, the effect size index most often used, transforms all effects into standard deviation units (Chapter 12). If d were computed to be .50, it means that the group mean for one group was one-half a standard deviation higher than the mean for the other group—regardless of the original measurement scale. Visual inspection of heterogeneity usually relies on the construction of forest plots, which are often included in meta-analytic reports. A forest plot graphs the effect size for each study, together with the 95% CI around each estimate. Inclusion criteria are the characteristics that a primary study must possess to be included in the meta-analysis.

In this research question for a systematic review, the researchers use which approach to determining the answer to the question: Are 24. clinical outcomes of nurse-led care for patients with rheumatoid arthritis similar to those produced by usual care? Randomized control trial Metasynthesis Meta-analysis Not a researchable question A Feedback: Questions for a meta-analysis are usually narrow, focusing, for example, on a particular type of intervention and specific outcomes. Key constructs should be conceptually defined—the definitions are critical for deciding whether a primary study qualifies for the synthesis. A randomized controlled trial is not a systematic review. Research questions in metasyntheses tend to be broader, so that they can fully capture the phenomenon of interest. The question is researchable.

Effects for studies with allmale (or predominantly male) samples could be compared to those for studies with all or predominantly female samples.
