Citation preview
A literature review involves the systematic
identification, location, search, and
summary of written materials that contain
information on a research problem.
Purposes of A literature Review
1. Source of research ideas
2. A search of previous work acquaints the
researcher with what has been done in a
field, there by minimizing the possibility of
duplication and increase the probability
that a new study will make a distinctive
contribution to knowledge.
3. Information on research approach.
4. Assessment of feasibility.
Scope of a literature reviews
I- Types of information to seek.
A-Research findings
C-Methodological information.
D-Opinions and view points.
E- Anecdotes and Clinical descriptions.
II- Depth and breadth of literature coverage.
The extensiveness of the literature
review depends on a number of factors:-
a- The nature of the document being prepared.
b- The researcher’s own level of knowledge.
c- Relevancy : research that is highly related to
your problem usually merits rather detailed
coverage.
D- Sources for the literature review
A. A primary source is a description of a research
study that is written by the original researcher
(s)
B. Secondary resource: IS a description of a study
prepared by some one other than the original
researcher.
The literature review should utilize primary source
whenever possible.
Card catalog: contains an alphabetical
listing of books under 3 categories:
a- Title.
b- Author
c- Subject heading.
Indexes: contains reference materials on
books and periodicals.
Example:
- Nursing intervention and pain relief for post operative
patients, (Joun), north Am. 11 (2): 283-95.
Nursing intervention and pain relief for post
operative pts (article title).
-(Joun) (author).
-North Am (Journal number).
-11 (volume number).
-(2) (issue number).
-283-95 (page number).
-Jun. 76 (date of issues).
-(research) (type of article).
1. International nursing index.
A articles from more than 275 nursing Journals,
more that 2700 non nursing journals covers
form 1966 to the present (quarterly)
2. Index medicus.
Nursing research index
Nursing studies index
Current index to journals in education
3. Abstracts:
provide a summary of a study rather than just a
title.
The abstract is a brief description of the study
placed at the beginning of the journal article. In
about 100 to 200 words.
The abstract answers the following questions,
what were the research questions? What
methods did the researcher use in answering
those questions? And what did the researcher
discover?
5.The summary:
Presents the high lights of the findings of a
study and is placed at the end.
4.Computer searches:
able to produce an immediate search, this is
called on –line search.
MEDLINE covers all areas of biomedical literature
with added coverage of nursing and dental
literature.
1. Identifying and locating relevant references.
2. Abstracting and recording notes:
- Examine the abstract or summary of a report in
order to determine its potential value.
3. Once the document is considered relevant, the entire
report should be read critically.
4. Use index cards:-
Separate cards should be used for each new reference to
facilitate organization and sorting.
Direct quotes should be avoided.
- It is important to paraphrase.
If the reference is a research reports the following kinds of
information should usually be recorded:-
1- The problem statement.
2- the procedures and methodology.
3- The results and conclusions.
4- The researcher’s own criticism or comments.
The review should point out both consistencies and contradictions in the literature.
Studies that are relevant to your study should be described in detail.
The summary should point out any gaps or areas of research inactivity.
The review should be as objective as possible.
The literature review should conclude with a summary or overview.
The critical summary should demonstrate the need for the new study.
1. Does the review seem thorough? Does it appear
that the review includes all or most of the major
studies that have been conducted on the topic of
interest? Does the review include recent
literature?
2. Is there an overdependence on secondary
sources when primary sources could have been
obtained?
3. Is there an overreliance on opinion articles
or anecdotes and an underemphasis on
research studies?
4. Is the review a summary of past work, or
does it critically appraise the continuations
of key studies? Does it discuss weaknesses
in existing studies and identify important
gaps in the literature?
5. Does the review conclude with a brief
outline of the state of the art of the
research on the Topic?
6. Is the review organized in such a way that
the development of ideas is clear? If review
is part of anew study, is the material
organized in such a way that the review
builds a case for conducting the new study?
7.Is the review paraphrase adequately, or is it a
string of quotations from the original sources?
8. Does the review use appropriate language,
suggesting the tentativeness of prior findings?
9. Does the review appear to be sufficiently
objective?
