To identify gaps in the body of knowledge
To identify new clinical interventions to test through research
To give ideas about appropriate conceptual frameworks
To gain information about a research approach
How have other researchers dealt with the topic?
What research designs, samples, and instruments did they use? 10/27/2010 4 Slide 5: Evaluate current practices and make recommendations for change
Researchers summarize literature relevant to their own studies in the introduction of the research report.
Both researchers and nonresearchers conduct literature reviews 10/27/2010 5 Scope of Literature Review : Scope of Literature Review Type of information to look for
Depth of Information
Type of Sources
Methods for conducting the Literature Review (or how the heck do I start?)
Skill worth cultivating – methods changing rapidly 10/27/2010 6 Type of information to look for : Type of information to look for Research findings
Primary vs. secondary sources
Found in journals (remember, journals differ in quality – look for referred journals which are reviewed by experts)
Also check books, conference proceedings, etc.
Textbooks are OK to review all information on a topic but are generally not cited in a written report 10/27/2010 7 Slide 8: THEORY
Works by authors of conceptual frameworks can yield research ideas and how information from research fits into the body of knowledge.
From research projects (as previously discussed)
Summaries of research
Books on measurement and existing tools for measuring variables 10/27/2010 8 Slide 9: Opinions
Good for background
Generally not cited except when given by very well known and respected scholar
Anecdotes and clinical description
Again, good for background but not used in written literature review 10/27/2010 9 Depth of Information : Depth of Information Depends on several factors:
How much is written on a topic
How broad the problem is – how many variable
Experience of researcher
For your projects: emphasize quality references not quantity 10/27/2010 10 Type of Sources : Type of Sources Primary Source = description of a project written by the author who conducted the project

ERIC (Educational Resources Information Center) – on computer
EMBASE (Excerpta Medical database)
PsycINFO (Psychology Information) 13 Conducting and Writing a Literature Review : Conducting and Writing a Literature Review Identify references

Be objective. Don’t leave out important references because you don’t like their approach or results
Finish with a summary of the problem and include what has been studied and where your study fits into the knowledge base.
Give more details on the more important studies. 10/27/2010 15 Slide 16: 10/27/2010 16
