The differences between research and evaluation
Developing a research question
○ Concentrate on important & changeable issues
○ Use needs assessment results to answer questions:
■ Perception of proposed program?
■ Extent of problem confirmed?
■ Project priority level?
■ Long-term increasing trend?
○ Who? Identify target population
○ What? Describe main purpose
○ When? Determine length of study
○ Where? Describe location of study
●
Role of the stakeholder
○
○
○
○
○
●
Plan, implement, and evaluate program
Empowered to sustain community projects
Embrace disenfranchised groups
Provide legitimacy to community partners
Diverse roles & power offer diverse perspectives
Types of evaluation
○ Formative
■
■
■
■
■
○
Aka “exploratory evaluation”
Conducted during planning & implementation phase
Includes qualitative and/or quantitative data
Data collected at each phase
Program modified as needed
Summative
■ Measurement about impact, outcome or benefits
■ Conducted by external evaluators
■ Uses quantitative data
○
Process
■
■
■
■
■
○
Examines program fidelity & implementation
Investigates the organization & administration
Monitors the feedback of the program
Investigates issues which influence implementation
Investigates the environment surrounding program
Outcome
■
■
■
■
Uses data to document short-term results
Descriptive data defines output activities
Documents stakeholders satisfaction level
Documents social influence on output activities

1932: Study of the progression of syphilis
600 African American men in Macon County, Alabama
399 participants had syphilis
201 participants did not have syphilis
Participants received free medical exams, meals and burial insurance
Were never allowed to quit participation in study
Did not receive treatment for syphilis
Never told that they were participating in a research study
Henrietta Lacks Respect for her cells

1951: African American woman diagnosed with cervical cancer
A piece of her tumor was used to grow a cell line for research
The immortal cell line was named HeLa
First human cell to grow in cultured medium
Her cells were used for 25 years after her death
Was not compensated for research profits
Medical Ethics-Basic ethical considerations
○ Respect for persons or autonomy
■
■
■
■
Persons are treated with respect
Given enough information to make informed decision
Autonomy reassessed throughout research
Individuals with diminished decision-making capacity need extra
protection
■ Self-determination and understanding of risks and benefits are
maintained
○
Beneficence
○
Justice
■ “Do no Harm” related to Hippocratic Oath
■ Assumes that risks are minimized as individuals and society benefit from
participation in research
■ •Researchers are required to stop study if participants are harmed
■ Fair distribution of burden and benefits
● Individual justice: specific volunteers are recruited because they
would potentially benefit from the research and other volunteers
are specifically not recruited due to undesirable traits or medical
conditions.
● Social justice: equal distribution of research benefit or burden
across the target population rather than a select portion of the
population
●
○
Nonmaleficence
○
Paternalism
○
Utilitarianism
■ relationship of uneven power between a health care provider and patient
■ the decision, behavior or action that achieves the greatest good for the
greatest number of people
IRB role
○

○
○
○
○
○
○
○
○
○
●
■ refraining from causing harm or acting with malice toward a person
Institutional Review Board
Approve, monitor and review research that involves human subjects
Protect the rights and welfare of the research subjects
Requirements for research approval from IRB committee include:
Research protocols and amendments
Written informed consent forms
Participant recruitment procedures and advertisements
Written information provided to participants
Research plan
Information about availability of compensation and schedule of payments
Safety information
HIPPA
○
○
○
○
○
1996: Health Insurance Portability and Accountability Act (HIPAA)
Individuals determine who may read or receive a copy their medical records
Add corrections to their medical records
Give permission for sharing health information
File a complaint with the health care provider, health insurer or the federal
government
Chapter 3
● Social determinants of health
○ Complex relationship of factors that influence an individual’s or population’s
health
○ Good health does not always equal the absence of disease
○ Healthy People 2020: improve an individual’s social and physical environments to
improve health
○ In research: must look at whole individual participating in study
○ When conducting research one must recall social disparities
○ It is helpful to make a list containing the headings:
■ Health provider concerns
■ Health disparities and social determinants of health
■ Ways to reduce barriers
○ Obesity
■ Multi-level condition
■ Lack of physical activity
○

●
■ Increased sedentary lifestyles
■ Leads to increase in chronic illnesses
■ Occurs over a long period of time
■ Investigate the physical, psychological and social aspects
Educational Disparity:
■ In research, these literacy suggestions should be followed:
■ Place the most important information first
■ Group information together to increase understanding
■ Write in active voice
Language Barriers
■ Determine an individual’s level of literacy in their native language before
assuming a lack of health knowledge
■ Use a translator when needed
■ Use simple 1-2 syllable words rather than standard medical terminology
■ Provide a phonetic pronunciation of medical terms
■ The readability score of plain language documents should not exceed a
5th grade reading level
Access to Health Care
■ Lack of insurance
■ Lack of transportation
■ Lack of funds to cover copayments and services not covered by insurance
company
■ Lack of access leads to increase in untreated chronic illnesses
■ Increased health care spending does not equal improved health and
longer life expectancy
Safe Food
Food Security
■ Availability of nutritious, adequate and safe food
■ Ability to acquire acceptable foods without stealing or using emergency
food supplies
Food Insecurity
■ A household economic condition of uncertainty about availability to
regularly obtain nutritious, adequate and safe foods
Hunger
■ An individual’s condition resulting from food insecurity
Employment
■ Lack of or inadequate employment causes decreased ability to obtain
food, education, health care, and childcare
■ If housing cost is over 50% of income, then homelessness risk is increased
■ Homelessness can lead to disability, domestic violence, mental illness and
addiction disorders
Safe Housing
■ Affordable Housing
○ A family paying less than 30 % of its annual income on housing
○ When cost a greater than 30% then difficulty paying for food, clothing,
transportation and medical care
Healthy People 2020
Health disparities
○ Health difference that is closely linked with social, economic, and/or
environmental disadvantage
○ Affect groups of people who historically linked to discrimination or exclusion
○ Lead to an individual’s inability to achieve & maintain optimal health
○ Interconnected with biological, environmental and lifestyle behaviors that
negatively impact health outcomes
●
MAP-IT
○ Mobilize, Assess, Plan, Implement, Track
○ Mobilize objectives
■ Gather a broad representation of key individuals and organize a
partnership/coalition
■ Identify roles for partners and organizations
■ Assign responsibilities to move process forward
○ Assess objectives
■ Assess both needs and resources in the community
■ Set priorities: Feasibility, effectiveness, and measurability
■ Collect State and local data to determine local needs
■ Explore social determinants of health related to the issue
○ Plan objectives
■ Use Healthy People 2020 to determine the goals and objectives
■ Clear objectives are needed in a good plan
■ Write concrete steps for achieving each objective
■ Assign responsibilities and activities to each team member
■ Search for best practices and other tested interventions
○ Implement objectives
■ Create a detailed work plan
■ Share reasonability by assigning a specific person to each activity
■ Celebrate accomplishments
○ Track objectives
■ Evaluate each segment to track progress over time
■ Check data collection for standardization, reliability and validity
■ Share progress with partners
■ If positive trend in data, issue a press release or announcement

○
○
○

●
Moves from theory to observations or findings
Moves from general to specific
1.Start with a theory
2.Develop a specific hypothesis to test
3.Collect observations to confirm or refute the hypothesis
4.Confirm theory
Inductive reasoning
○
○
○
○
○
1.Observe specific behaviors and measures
2.Identify specific patterns among the collected data
3.Formulate a proposed hypothesis
4.Develop a conclusion, model or theory
5.Other researchers repeat the observations to confirm or refute the theory
Types of theories and models
○ Universal Theories
■ Gravitational theory: theory of gravity and relativity
○ System Theories
■ Break apart a concept for the purpose of studying each segment
independently
■ Examples:
■ Theory of Goal Attainment
■ The Ecological Model
●
Theory of goal attainment
●
Ecological model
●
Social Networks and Social Support Theory
●
Diffusion of Innovations Theory
○ Focuses on personal system concepts, interpersonal system concepts and social
system concepts
○ Focuses on how the nurse interacts with patient and the environment to achieve
maximum well-being
○ Multiple level investigation includes:
■ 1.Individual as a whole or the personal system concepts including
perception, self, body image, personal space, time and coping
■ 2.How the individual perceives their environment or interpersonal
system concepts (objects, persons, events, stress, and communication)
■ 3.Social system concepts (authority, power, status, and organizations)
○ Developed to recognize how behavior change occurs when individuals have
social networks and social support in their community
○ Some support services are conditional (support until fail-to-pay)
○ Social support include the following characteristics:
○ Emotional support
○ Instrumental support- tangible support
○ Informational support
○ Appraisal support- self evaluation
●
RE-AIM model
○ To evaluate program interventions to determine the impact of programs
○ Programs are assessed at the individual, organization, and community level using
five dimensions:
■ 1.Reach
■ 2.Efficacy
■ 3.Adoption
■ 4.Implementation
■ 5.Maintenance
●
Health Belief Model
● Transtheoretical Model
Chapter 5
● Reliability
○ ways to establish reliability
■ Related to consistency or ability to repeat results
■ A test is reliable if the results are the same each time it is used with the
same individuals
■ It is not possible to calculate reliability, researchers can only estimate
■ Stability
● When the results of a survey or instrument are consistent over
time
● Test-retest technique
●
○ measurement of reliability
Validity○ Internal
■ History
● When an event happens during research that influences the
behavior of participating individuals
■ Maturation
● The natural changes that occur over time with individuals
■ Testing
● Differences noted from pretest to post test that can be attributed
to students becoming familiar with the test
■ Instrumentation
● Measures changes in respondent performance which cannot be
credited to the treatment or intervention
■ Regression
● Some respondents performing well on pretests and poorly on
posttests or vice versa merely by chance
■ Ceiling and floor effects
● Ceiling effect is when all participating individuals perform
extremely well on a pretest and posttest
● Floor effect occurs when individual performance starts out low
a\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\ion
● Individuals lost from the study
■ Selection
● When participating individuals are different at the onset of the
study
■ Hawthorne effect
● Workers at the Western Electric Company in Hawthorne, Illinois
improved their performance when they know that they are being
watched
○
external (types of each)
■ Population
● When population selection is so specific, treatment is matched to
a specific sample and doesn’t apply to a wider population
■ Environment
● The change from a controlled environment to a less controlled
environment vice versa
■ Temporal / Sequential
● Change in external events
■ Participants
● ◦Animal to human links
● ◦Human to human links
● ◦Gender bias
● ◦Racial bias
● ◦Cultural and ethnocentric bias
■ Testing and treatment interaction
● If participants learn from the pretest, then they may be less likely
to learn as much from treatment
■ Reactive arrangements
● If individuals change their behavior when observed (threat to
internal validity), results are not generalizable to real world
conditions (threat to external validity)
■ Multiple treatment conditions
● Multiple treatments may create an artificial setting that does not
exist in the real world, so results are not generalizable
●
●
Threats to validity-know the types
Measurement errors
○ Random errors
■
■
■
■
Occur by chance and are inconsistent across the respondents
Increase or decrease results in an unpredictable manner
Researchers have no control over the occurrence of random errors
Reduced through statistical methods by averaging scores over a larger
sample size
■ Influences reliability
○ Systematic errors
■ Consistent in the same direction (all results have the same error)
■ Introduce inaccuracy and bias into the measurement
■ Problematic to detect and eliminate
■ Not possible to reduce the effect of systematic errors through statistical
methods
■ Influences validity
■ Occurs in three areas: Environment, Observation, Drift
○ How to reduce
■ Collect data from a larger sample size
■ Pilot testing
■ Data collection training
■ Double data entry
■ Statistical consultation
■ Triangulate data collection
Chapter 6
● Qualitative data
○ Advantages
■ Useful for complex subjects
■
■
■
■
■
■
○
Disadvantages
■ Not needed for simple hypothesis
■
■
■
■
■
■
●
In-depth and comprehensive information
Greater understanding of entire situation
Interactions between variables
Generates useful data
Not dependent on large sample sizes
Unique results
Subjective; difficulty establishing reliability and validity
Limited scope due to data collection approaches
Possible researcher bias
Requires detailed planning
No precise results with mathematical calculations
Not able to be replicated; lacks generalizability
Types of design
○ Observations
■
■
■
■
■
■
■
○
•Participant and non-participant observation
•Obtrusive and unobtrusive observation
•Natural or contrived observation
•Disguised and non-disguised observation
•Structured and unstructured observation
•Direct and indirect observation
•Human and mechanical observation
case studies
■ A thorough exploration on a specific topic
■ •An analysis of narrow and detailed variables describing individuals,
groups, social units or situations
■ •Focus on the individual unit rather than the population
■ •Not generalizable but concentrate on greater understanding of specific
topics
○
Phenomenology
■ The study of human experiences and interpretations of an occurrence
within a population
■ •Explores an event or situation within a study population
■ •Researchers are not searching for accuracy but rather perceptions of
events
○
historical documents
■ •Study the details of past events
■ Possible source materials to study include newspapers, magazines, legal
and medical documents, textbooks, periodicals, training manuals,
photographs, etc.
■ This information is useful in planning future events
○
content analysis
■ A collection of existing documents on a specific topic:
■ One type of document over time
■ Different types of documents on a specific topic during a specific time
period
■ Various personal documents on a specific topic
■ Each document collection is analyzed to get an in-depth view
○
Ethnography
■ A combination of interviews, observations and case studies with
emphasis on the relationship between behavior and culture
■ A researcher team studies a particular location or population to gain
greater understanding to address researcher questions
■ Is labor intensive and involves extensive time on location
○
grounded theory
■ Used to generate new theory based on a process of comparison
■ Steps include:
● Develop a hypothesis
● Collect data about the topic from a variety of sources
● Select certain documents and make comparisons
● Accept or Reject some documents
● Repeat process until reach “saturation”
●
Be able to explain techniques for used in analysis of qualitative data
○ Broad holistic or big picture view of the data
○ Collaborative partnerships from various and opposing viewpoints
○ Detailed descriptions of the studied topic across multiple data sources to seek
regular patterns or trends
○ Involve sifting through data, coding data, and sorting data over and over again as
each observation or interview is added to the data collection
○ Data organization
■ Manual
■ Notebooks
■ Boxes and file cabinets
■ Computers
■ The tool of choice for organizing data
■ Open Source: Coding Analysis Toolkit (CAT)
■ Proprietary: ATLAS.ti or Nvivo
■ Cannot analyze the complex meanings and perceptions explored in
qualitative research
○ Coding data
■ Data reduction
■ Organize the data
■ Identify emerging themes, categories, and patterns
■ Test hypotheses against the data
■
■
■
■
Priori codes
Described by researchers prior to starting data analyses
Exploratory codes
Added to the a priori codes as data are collected and analyzed once new
themes emerge
○ Data display
■ Data is displayed in tables, diagrams, charts and graphs
■ Frequency tables are used to describe categorical data, such as
demographics
■ Diagrams provide a visual depiction of volumes of data
■ Charts and graphs show chronological order or categories
Chapter 7
● Constructs
● Variables- types
○ Independent variables
■ Manipulated, causes change
○ Dependent variables
■ Affected by the IV
○ Mediating variables
■ Acts between the IV and DV.
○ Moderating variables
■ Show how relationships change with different variables (e.g. age)
○ Confounding variables
■ Extraneous, interfere with IV and DV
○ Controlled variables
■ Held constant to eliminate interference.
○ Categorical variables
●
Operational definition- why is this important
○ Based on constructs as well as the research questions
○ Researcher must provide clear and concise definitions for each construct used
○ Select a dictionary definition or provide a more specific definition suited for the
research
●
Quantitative research designs
○ True experimental
■ When random assignment is used to determine how participants are
assigned to groups
● True Experimental Design includes:
● Manipulating the independent variable
● Exploring cause and effect relationships
● Random assignment of participants to equivalent groups
○ Research blinding (Blind Study)
○ Double-blind study
○
Quasi-experimental
■ Does not use random assignment
■ Researchers do not manipulate the independent variable
■ Research results yield limited generalizable conclusions
■ The assignment is based on factors such as cost, convenience, feasibility
or some other criteria
■ Also if the design involves using multiple waves of enrollment
○
Nonexperimental
■ Used when there is no need for group assignment
■ The most common design
■ Non-Experimental Research involves:
● No manipulation of the independent variable
● No random assignment of participants
● No cause and effect conclusions due to alternative explanations
● Uses mostly descriptive statistical analysis
●
Group assignment- types
○ Random group assignment
■ Conducted using a variety of methods
○ Quota group assignment
■ Researchers use census data to determine what percent of individuals
are in each group
○ Every nth group assignment
■ Researchers select individuals or data in a preset and specific pattern
