What's a Literature Review? Here is a nice summary from Purdue OWL.
1. Determine an intervention in use at your field site, or an intervention that could be used there. Consider PICOT: Population, Intervention, Comparison (optional), Outcome, and Time (optional).
2. Systematically search the literature (published evidence in the form of scholarly articles) using the databases suggested on this guide. Primarily you'll use empirical articles, which report on research the authors conducted. See more below about how to identify if an article is empirical.
3. Carefully read the articles & determine what the evidence suggests. Is the intervention effective? Is it more effective for some populations?
4. Cite your sources as you indicate what we know from the published literature about the intervention.
5. Don't be afraid to be critical of your sources. Are sample sizes small? Was the population studied non-diverse? How do these and other limitations (which articles usually list toward the end) influence the applicability of the results?
These links provide lists of interventions that are based on research. If you browse by intervention, citations for peer-reviewed articles may be included that you could find & use for your paper.
