Research Literature Review
Introduction to Literature Review
A literature review systematically identifies, analyzes, and summarizes written materials on a research problem. It grounds studies in existing knowledge.
Purposes of a Literature Review
Identifies research problems and refines questions/hypotheses.
Reveals gaps, inconsistencies, and replication needs.
Guides design/method selection and avoids prior pitfalls.
Helps interpret findings and develop recommendations.
Types of Information in Literature Reviews
Facts/Findings: Results from prior studies (e.g., journals, reports).
Theory: Conceptual frameworks for the problem.
Methodology: How studies were conducted (designs, variables, analysis).
Opinions/Beliefs: Subjective viewpoints (limited use in reviews).
Anecdotes: Clinical experiences (less reliable).
Sources of Literature
Primary Sources: Original research by the author (e.g., journal articles).
Secondary Sources: Summaries/interpretations by others (e.g., review papers).
Prefer primary sources to avoid bias.
Search Methods
Manual Search: Using keywords in catalogs, abstracts (e.g., "pressure ulcer prevention").
Computer Search: Databases like CINAHL, MEDLINE, ISI (limit by date, document type).
Characteristics of a High-Quality Review
Comprehensive (up-to-date, thorough).
Well-organized and clearly written.
Reproducible (consistent criteria for conclusions).
Steps in Conducting a Literature Review
1.Locate Literature: Use databases/keywords.
2.Screen References: Assess relevance via abstracts.
3.Document Searches: Record keywords, sources.
4.Abstract/Record Notes: Summarize hypotheses, methods, results.
5.Organize Review: Logical outline (what’s known/unknown).
6.Write Review: Integrate findings, highlight consistencies/inconsistencies.
Reading Research Reports
Sections:
1.Abstract: Summary.
2.Introduction: Problem, purpose, theory, literature.
3.Methods: Design, sample, data collection.
4.Results: Findings, statistical tests.
5.Discussion: Interpretation, implications, limitations.
6.References: Cited works.
