Searching and Critiquing the Evidence
Bring to mind the various practice problems you and your colleagues have been considering in this course. What insights might the literature provide with regard to these issues? How should you evaluate the research? And, why is it important to review and critique this information?
This Discussion addresses strategies for searching the literature in order to critique existing evidence. Please note that this Discussion is related to Application Assignment #4, which is assigned this week. You are strongly encouraged to read through that assignment now.
• Recall the practice problem (CARE COMPLEXITY) and theoretical framework (OREM’S THEORY OF SELF CARE) you identified for the Week 5 Discussion. Using the Walden Library and other professional databases, conduct a search and locate four (4) appropriate primary research articles, one of which is a systematic review.
• Review the articles and determine what level of evidence they represent. Using the critique strategies presented in the Learning Resources as a guide, consider how the articles you located either support or weaken the merit of your theoretical framework or the importance of your practice problem.
POST a cohesive response that addresses the following:
• How does the literature strengthen or weaken the merit of your selected theoretical framework and practice problem?
• What levels of evidence are most prevalent in these articles?
• Why do you think that level of evidence is most prevalent?
MUST USE A MINIMUM OF 4 OF THE RESOURCES BELOW AND ANY OF THE SUPPORTING RESOURCES FROM ARTICLES.

Chapter 3 provides an overview of quantitative research, the concepts associated with this type of research, and different quantitative research designs.
• Chapter 4, “Introduction to Qualitative Research”
Chapter 4 describes the philosophy of qualitative research and provides examples of how it is used in nursing research. Understanding the basic principles of quantitative and qualitative research is necessary to effectively critique research literature.
