Chapter 4 Flashcards
Research Review
Synthesizes exisiting knowledge on a specific question and draws new conclusions
Initial and Independent reserach project
Lit Review vs Research Review
mLit review guides forulation of research questions/hyoptheses, research review you make new contributions and arguments
4 Independent Research Reviews
Integrative
Theoretical
Methodological
Policy-oriented
Integrative Research Review
Summarizes past research addressing similar/related hypotheses, highlight issues left unresolved, directs future research
Theoretical Review
Summarizes existing theories used to explain particular topic
Methodological Review
Summarized different designs used to study topics, identifies strengths and weaknesses for each
Policy-Oriented Review
Draws out policy implications of topic
Research Review 5 step process
Identify topic
Prepare coding sheet
Search for research publications
Synthesize research publications
Reporting previous research
Coding Sheet
Collects summary info from articles to be reviewed, necessary if # of studies to be reviewed is large and gets all info in one reading
If you have multiple coders for a coding sheet,
need training to speak the same language, have the same lens
Having blank spaces in a coding sheet is
normal, not all studies report what a researcher searches for
Research reviews must specify _____ population
target
An ideal research topic contains ___ to ___ concepts
2-3
Boolean Operators
And, Or, Not, making searching more precise
Pubmed (includes medline)
premier database for biomedical literature, over 15 million citations
Cochrane Library
reviews evidence for and against effectiveness/appropriateness of health care services
PsycINFO
abstract database of psychological literature
EMBASE
Similar to PubMed
Biosis
Life science abstracts
MeSH Terms
Medical Subject Headings, created by National Libraries of Medicine, indexes/organizes PubMed articles
Where is MeSH (medical subject headlines) applied?
In MEDLINE, each article in medline associated with MeSH terms describing content
Purpose for application of quantitative procedures
tend to be mroe standardized and objective, provide integrated summaries
Meta-analysis is a ________ procedure
quantitative
Meta analysis is
stat analyses combining and interpreting results of indepdeent studies of a given scientific issue for purpose of integrating findings
Fundamental assumptions in meta-analysis
same conceptual hypothesis/research question assumed for all studies
Separate studies included in analysis are indepedent of each other
Qualitative Procedures in Research Review
Address nonquantifiable features of study
Often used in theoretical reviews, study things with policy relevancy
Strengths of Research Review
Contributes to advance of scientific knowledge
Less expensive
Fewer staff
Weaknesses of Research Review
Constraints on materials available for review –> assumptions must be made
Some limitations represent pervasive concerns in primary research
