Literature review
A written summary of the state of evidence on a research problem
Summary of current empirical and theoretical literature…the author writes it so that it describes the rationale and background for the study
A description of the study problem, why the problem is important, and why it needs to be studied
The primary purpose of literature reviews is to…?
Integrate research evidence to sum up what is known and what is not known
What is literature?
Broad term for many types of things
Journal or periodical…same thing
- mostly articles in journals
- also ads for schools and jobs in journals
- NOT a magazine (ex: better homes and gardens)
Monograph = book containing a detailed report of a study
Books
-ex: textbooks
Theses and dissertations (always research)
MSN or DNP project (may or may not be research)
Types of journals in the literature
Refereed journals:
- peer-reviewed; blind review; external review
- reviewers determine quality and scientific merit of manuscripts and whether they should be published (blind review is good b/c it means reviewer gives honest opinion)
Non-refereed journals:
-non-peer-reviewed, journal editor makes the decision about publishing
What are the 2 major types of articles?
- Research articles (empirical literature)
2. Non-research or conceptual articles
Grounded theory researchers typically begin to collect ___ before examining the literature.
Data
Phenomenologists often undertake a preliminary ____ search at the outset of a study.
Literature
Ethnographers often familiarize themselves with the literature to help shape their choice of a ____ problem before going into the field.
Cultural
Research articles (empirical literature)
follows steps of research process
answers questions or hypotheses
presents all components of the study
may be qualitative or quantitative
may be report of a single study or more
may be a report of a systematic review
- research synthesis (qualitative)
- meta analysis (quantitative)
Research synthesis is?
qualitative
Meta analysis is?
Quantitative
Research article format
Title Abstract Introduction* -background, purpose, question/hypotheses Methods* -design, participants, materials, procedure, statistics Results* Discussion* Conclusion References
*IMRAD format
Non-research or conceptual articles
how to…
new processes, techniques, standards and guidelines
-could be guidelines the first time they come out
informational e.g. profile of a disease, etc.
editorials
may be clinical or non-clinical
any article that is NOT research
Original studies
The person who wrote the article did the study
Secondary analyses
Person who wrote the articles did the study but asks a secondary research question
What are the 2 literature sources?
Primary sources
Secondary sources
Primary source
Written by the person who conducted the study, the original researcher
ex: report of a study
Secondary source
A description or summary of a study prepared by someone other than the original researcher
-ex: textbook and brochures
Websites are secondary sources (depends what’s on the website)
-ex: a website that reports statistics would be considered a primary source vs the CDC website (good info but it’s secondary info) is a secondary source
Age of articles
Articles should be as current as possible and relevant
Ideally no older than 5 years
-however, maybe a 15 year old article is the only article on that topic - just mention in the research article that the references is the most recent one available (or it’s necessary to fully explain what you’re talking about [ex: seminal work])
Typically expect articles on the reference list to be 3-5 years old
Classic article, seminal work, or landmark study refers to an article or book that changed everything, changed the paradigm…article by Watson and Crick about the double helix and DNA
purposes of literature reviews: Quantitative literature
Document the background and significance of the study
ID theoretical or conceptual work
ID data collection tools
ID what’s already known
purposes of literature reviews: Qualitative literature
provide a basic understanding of the study problem
provide evidence that the study conducted was appropriate and based on current knowledge of the problem
describe the “fit” between the present studies and previous studies
What are the 3 search strategies for finding literature?
- search for evidence in bibliographic databases
- ancestry approach (“footnote chasing”)
- citations from relevant studies are used to track down earlier research on which the studies are based (the “ancestors”) - descendancy approach
- find a pivotal early study and search forward in the citation indexes to find more recent studies (“descendants”) that cited the key study
Phenomenological
compares and combines study findings w/ literature
Grounded theory
uses literature to explain, support, and extend theory
