2. OTHET ADDITIONAL RESEARCH
DESIGN
Some research design which cannot be categorized
under either experimental or non experimental
research design are categorized under this group.
5. DEFINITION
Quantitatively combining & integrating the
findings of the multiple research studies on a
particular topic is known as METAANALYSIS.
GLASS (1976) coined the term “META
ANALYSIS”.
It refers to the analysis of ANALYSIS.
6. A Meta Analysis statistically combines the result of
several studies that address a shared research
hypothesis.
Meta analysis summarizes data from several
individual studies that concern a specific research
question.
7. It is believed that finding from each individual
studies may not be effective or powerful enough
to allow for decisions affecting clinical practice.
However, when result of several similar studies
are integrated , the finding of such studies may
be more effective or powerful.
8. Meta analysis studies start with selecting studies
with similar variables and population sample,
followed by identifying study characteristic and
statistically analyzing and reporting the assessed
findings of the study.
9. SECONDARY DATAANALYSIS
Is a research design in which the data collected by one
researcher is analyzed by another researcher.
Secondary Data Analysis is usually carried out to test
a hypothesis.
The researchers analyze the data collected in the
previous researches, but they have a new research
question or may test a new hypothesis.
10. Secondary Data Analysis is considered to be the
most convenient, time saving, & cost effective.
E.g. A research study on factors affecting
lung function (from a study on Major lung
Diseases)
11. METHODOLOGICAL STUDIES
Methodological studies are conducted to develop,
validate, test the research instruments.
The main problem in nursing is to find out appropriate
measurement tools to measure nursing related
phenomena.
Nurses frequently use tools developed by other
disciplines such as psychology, sociology etc.
12. METHODOLOGICAL STUDIES
These tools from other disciplines can be useful if
they are found appropriate but most f the time these
tools are used because of the unavailability of reliable
and valid research tool.
13. OUTCOME RESEARCH
Outcome Research is planned to assess or record
the end result of a care/ service/ activity.
These studies are conducted in response to the
increasing demand from the public to justify the
care practices & systems to improve the outcome
of a care service & aims at cost reduction.
14. This research methodology is the result of
demands by the Professional Standards Review
Organizations for quality assessments & quality
assurance.
The outcome researches justify existing care
practices & systems in place.
15. EXAMPLE
1. An outcome research on the effectiveness of
QUALITY ASSURANCE PROGRAMME
(QAP) implemented in a hospital, Tamil Nadu,
India.
2.An outcome research on client satisfaction with
existing cosmetic products in the local market.
