Discussion: Study Approaches

Researchers use many different approaches to find the answers to their study questions. Study approaches include case series, cross-sectional, case-control, cohort, experimental, qualitative, and correlational. Each approach has its advantages and challenges.

For this Discussion, you will consider the many ways in which you could answer your research question. If you are considering an experimental method, consider the types of experiments. You may want to consider administering a survey, but you need to also consider the type of survey. One key element to valid research is the selection of the study approach.

To prepare for this Discussion:

  • Consider your research topic and the results of your literature review
  • Review the different study designs presented in the textbook (Chapters 7–14)


Post a comprehensive response to the following:

  • What type of study design would you use for your proposed study (case series, cross-sectional, case-control, cohort, experimental, qualitative, or correlational)?
  • Why is the approach you selected the most suitable to support your study question?

Read a selection of your colleagues’ postings.


Respond to at least two of your colleagues’ postings in one or more of the following ways:

  • Suggest an alternate study design that would be appropriate for your colleagues’ study question and explain why that study design is appropriate

Return to this Discussion in a few days to read the responses to your initial posting. Note what you have learned and/or any insights you have gained as a result of your colleagues’ comments. You are not required to post these final insights.
