Epidemiologic Study Designs
As introduced in the first few weeks of this course, investigators use various epidemiological study designs to study health problems and the effects of health interventions. You have examined several study designs, including descriptive designs (in Week 2) and analytic study designs that are observational (in Week 3) or experimental (this week). As an MSN or DNP student, you should be able to determine which study design would be most suitable for addressing a health problem of interest to you, as this is a foundation for evidence-based practice.
For this Assignment, you will identify an epidemiologic association of interest (e.g., smoking and lung cancer, obesity and heart disease, hormone replacement/modification therapy and breast cancer) and determine an appropriate study design for exploring that association.

To Prepare
· Consider an association between a risk factor and a particular health outcome that is of interest to you. Table 2.2, in Curley, has some excellent options. You may use this to guide your selection of topics or select your own population health topic.
· Then, select an observational OR experimental study design you think would be the most appropriate for exploring this association. You may select from any of the designs covered in this module.
The Assignment
In a 4-page paper, not including title page and references, address the following:
· Briefly identify the population health topic (association between a risk factor and a health outcome) you selected. Present a research question based on this topic that you would like to answer in a proposed study. (Consult the Walden “Developing Research” resource for guidance on crafting a research question.)
· Explain the epidemiologic study design that would be most appropriate to assess and address your population health problem.
· Summarize the data collection activities you would use (i.e., how you would collect data—online survey, paper/pen, mailing, etc.).
· Explain any specific methodologic strategies you would use. For example, if you were conducting a case-control study, how would you select your cases and controls?
· Consider the methods you would use to make these selections. What are the strengths and limitations of your selected approach?
· Explain ethical considerations pertaining to your study.
