De’Vоhn Rоmаn Dоctorаl Quаlifying Exams Fall 2024 ---- Day #3 (Research) ---- Please read the following scenario and respond to each of the questions below it. Suppose that you are part of a research group that has interests in the development of school-based treatments for mental health concerns in middle school students. You have been asked to plan a study that fits within the general interests of the group. Your response to this item should be a draft proposal for the study. Please make sure you explain the rationale for your decisions and the limitations of your proposal. Within the draft you should address the following issues: Formulate a specific research question (or questions) that would be addressed through the research. Discuss the significance of the question(s) from a theoretical, practical, and/or policy point of view. Describe who will participate in your study. What are your inclusion/exclusion criteria? How will you select participants? How many participants will participate? What research design will you use? What are the advantages and limitations of this choice? Describe the procedures you will use. What data will be collected? How will reliability, validity, and/or credibility be documented? Describe the procedures for data analysis that you will use. What assumptions underly these methods and how will you evaluate the tenability of these assumptions? Identify and discuss limitations to your research, ethical considerations, and challenges that may arise in the conduct of the study. Discuss any other issues that you think are relevant to the conduct of this study.
