Types of literature Reviews

Traditional or Narrative literature Review

• Critiques and summarizes a body of literature
• Draws conclusions about the topic
• Identifies gaps or inconsistencies in a body of knowledge
• Requires a sufficiently focused research question

Weaknesses:

• A large number of studies may make it difficult to draw conclusions
• The process is subject to bias that supports the researcher's own work.

Systematic Literature Review

• More rigorous and well-defined approach
• Comprehensive
• Published and unpublished studies relating to a particular subject area
• Details the time frame within which the literature was selected
• Details the methods used to evaluate and synthesize findings of the studies in question

Meta-analysis

• A form of systematic review (reductive)
• Takes findings from several studies on the same subject and analyzes them using standardized statistical procedures
• Integrates findings from a large body of quantitative findings to enhance under-standing (study=unit of analysis)
• Draws conclusions and detect patterns and relationships

Meta-synthesis

• Non-statistical technique
• Integrates, evaluates and interprets findings of multiple qualitative research studies
• Identifies common core elements and themes
• May use findings from phenomenological, grounded theory or ethnographic studies
• Involves analyzing and synthesizing key elements
• Goal:  transform individual findings into new conceptualizations and interpretations
