Sonia A. Duffy, PhD, RN Lisa Kane Low, PhD, CNM, FACNM Huey-Ming Tzeng, PhD, RN What is a Literature Review? An extensive examination of research sources to generate a picture of What is known and not known about a clinical problem to determine if the knowledge is ready for use in practice Literature Review 3
Purpose of the Literature Review (1) Clarify the research problem Verify the significance of the research problem Specify the purpose of the study Identify relevant studies and theories Develop a research framework Clarify objectives, research questions, or research hypotheses Literature Review 4 Purposes of the Literature Review (2)
Develop definitions of major variables Identify limitations and assumptions Select a research design Identify methods of measurement Direct data collection and analysis Interpret findings Literature Review 5 Critiquing the Literature Review Are relevant studies identified and described? Are the studies critiqued by the researcher?
Are the references current? Is a summary of current knowledge provided? Also see the assignment guideline, entitled Major content sections of a research report and related critiquing guidelines Literature Review 6 Information Required within Seconds Systematic reviews, periodically updated, of randomized trials of the effects of health care
Literature Review From all sources, in all languages The Cochrane Collaboration: www.cochrane.org 7 Review the Following Terms What is conceptual literature? What is data based/empirical literature? What are the differences between primary and secondary literature? What are the advantages of each of these
four types of literature? Literature Review 8 Conceptual Literature Literature that deals with ideas and topics from a theoretical or personal point of view Not include research studies or other data based literature The advantages of conceptual literature include:
Literature Review A perspective that may be personal or subjective to an expert or one that provides an overview of a large amount of knowledge Sometimes this may be all we know, i.e., there is no empirical literature on a topic 9 Data Based/Empirical Literature In this type of writing, we see work that has gone through a formal process of research or scientific analysis There is DATA that is used to demonstrate a
point An advantage would be that there is an OBJECTIVITY not found in conceptual literature One must be careful, after all, researchers are human and are certainly capable of skewing data! Literature Review 10 Primary Literature This is literature where the author is the actual developer of the material
Example: Jean Watsons writing about how the theory of caring can be applied to CHF clients Example: Jones reporting on the results of her study on outcomes In this case the work is FRESH from the horses mouth, so to speak. The primary advantage of primary literature! Literature Review 11 Secondary Literature
The author presents the work of another, such as a theory or a study Literature Review Example: The writer writes an article about how he or she used Jean Watsons theory of caring or how his or her students like that work Example: The writer summarizes the literature in a particular area from, such as, a review of the literature on pain treatment
12 Summary of Review the Important Terms A good literature review for a research study takes all these types into consideration There should be a preponderance of primary data based literature Secondary and conceptual literature may round out the review but should NOT be the dominant forms The only exception would be if there is NO data based literature Literature Review
