This is for a nursing research class. Review the differences in predictive and prescriptive studies and select a predictive or prescriptive article that you found in your literature search. What are the independent variables (IV), dependent variables (DV), and mediating variables (MVs) that you find in the article? How do determining IVs, DVs, and MVs help you discern the theory tested in the research? In your particular article, what risk factors are identified, or what recommendations are provided?
