Searching for relevant literature on a given topic can sometimes be a frustrating process. In some instances, you might have trouble finding anything at all of relevance, whereas in other cases, you might find overwhelming amounts of potential resources and have to determine which is the most relevant to your search. Literature searches can be very rewarding when you find a perfect evidence-based article or research piece that precisely addresses your area of concern.
For this Discussion, you focus on conducting literature reviews and on locating and identifying the most relevant current literature.
To prepare:
Review this week’s Learning Resources on conducting a literature review.
Go to the Walden Library website, and explore tools for generating search terms.
With your PICO question in mind (regardless of approval status), identify at least 10 different search terms you could use in your literature search.
Reflect on how to assess the relevance of specific research to your PICO question.
Consider techniques for performing alternate types of searches if few or no resources are located.
By tomorrow 01/03/2017 11pm a minimum of 550 words in APA format with a minimum of 3 references from the list below. Include the level one headings as numbered below:
1) Post your PICO question (first draft if not yet approved) and the 10 search terms you plan to use in your literature search.
2) Describe one of the literature search tools you identified (e.g. CINAHL or Medline, or ProQuest etc..) in the Walden Library and where it is located.
3) Explain how you can assess the relevance of the research you review.
4) Finally, describe strategies for performing alternate types of searches if initial searches do not yield sufficient resources.
