The pre-proposal should contain the following components: 1. Aim(s): Number and list each research aim clearly and, ideally, in question format. For example, “What are the prevalence rates of psychiatric disorders among youth in detention?” 2. Justification: In outline form, succinctly explain the key omissions in the literature which your project intends to address. 3. Study Design: Briefly list your ideas for each component (see below). These decisions need not be final, but should demonstrate how you are thinking through your research plan. a. b. c. d. e. f. brief overview of your design (generally one paragraph) data collection site(s) type of sample, including inclusion and exclusion criteria sampling procedures data collection procedures measures 4. Key Variables: For each research aim list: a. Key dependent variable(s) and the variable structure. Are your dependent variables yes/no variables or otherwise categorical? ordinal? interval/ratio? b. Key independent variable(s) and the variable structure. Are your independent variables yes/no variables or otherwise categorical? ordinal? interval/ratio? c. Control variables, mediators, moderators (or your thinking so far), and the variable structure. Are these variables yes/no variables or otherwise categorical? ordinal? interval/ratio? 4 RESEARCH PROPOSAL REQUIRED COMPONENTS DUE: JUNE 11, 2014 1. Provide the context for your study. Start with the most general statements and end with the most specific. 2. State Your Research Questions. What do you intend to accomplish and/or what hypotheses will be tested? 3. Justify need for your study by critiquing the literature. Provide background for your proposal. Critically evaluate existing knowledge in the area. Delineate the key omissions in the literature which your project will address. Provide a table summarizing the literature. Use your literature table to argue the key omission in the literature and the need for your study. (One uses a literature table the same one uses quantitative tables in a results section). 4. Tell the reader why your study is important. You may have a section, “Conceptual Approach,” if necessary; you may include a figure (chart) outlining the relationship between your variables. Alternatively, if your topic is related to public health policy, you may include instead a section summarizing the importance of your research question for guiding public health policy. 5. Specify your methods. Begin by informing the reader of your overall plan. This can be done in less than a paragraph. You then need to include the following categories of information. In each category, you need to give the reader the rationale for your methodological choice. Be aware (and make the reader aware, if appropriate) of the potential difficulties and limitations of the proposed procedures. a) Data-collection site. Describe in detail, including the rationale for your choice. Do not choose a site only because it is convenient. b) Participants. Describe the characteristics of the subject population such as age range, sex, ethnic background, health status. Identify criteria for inclusion and exclusion. c) Sampling Procedures. Describe your recruitment strategy, including the circumstances under which consent will be sought and obtained who will seek it, the nature of the information to be provided to prospective participants, and the method of documenting consent. d) Sample size. Provide a rationale for your sample size. Although you do not have to do a power analysis for such techniques as ANOVA, outline the steps you would take to set your sample size, with appropriate references. For statistical techniques where power analysis is inappropriate (e.g., correlational studies), detail the rationale for your sample size. e) Design. Outline your rationale for choosing your design. If appropriate, diagram your design. f) Data Collection Procedures. Outline your procedures so that the reader can envision your study. g) Instrumentation. Describe the data collection protocols you will use and delineate the sequence of data collection. Identify the source of research material, i.e., whether the data consist of existing records or will be obtained specifically for your study. If your study incorporates existing measures, specify the rationale for your choice and the relevant reliability and validity information with appropriate cites. If the goal of your study is such that an adequate instrument does not yet exist, you do NOT need to develop a measuring instrument. However, include in your proposal the procedures you would undertake to develop such an instrument. 5 h) Variables and hypotheses. For each aim, list your key variables, specifying their type (dependent, independent or “control”). Ideally, list your variables in a table. List your hypotheses along with their direction, if appropriate, e.g., “the combination of drug treatment and therapy will be more effective in reducing recidivism than either drug treatment or therapy alone.” You may include your hypotheses in your table. i) Data analysis. Include the means by which the data will be analyzed and interpreted. Specify the type of data and discuss, in detail, the rationale for your choice of statistical procedures. You do NOT need to include any statistical calculations. If you wish, you may provide mock tables. j) Training. Include information concerning your procedures for training staff responsible for data collection (or coding if needed) such as interviewers, including acceptable levels of reliability. k) If needed, summarize the strengths and limitations of your study. You may include these in a 3column table including, for example, the issue (e.g., generalizability) and the strengths (column 2) and weaknesses (column 3). 6. Human Subjects. Discuss: (a) potential risks to subjects (physical, psychological, social, legal, etc.) and assess their likelihood and seriousness; (b) ways to protect the subject from risks or minimizing potential risks. If there are risks, discuss why they are reasonable in relation to the anticipated benefits to the subjects and/or in relation to the importance of the knowledge resulting from your study. Provide a consent form. Please note that your topics may require a different organization. Although the above information must be included, the subheading structure of your proposal may be somewhat different than this example. 6
