research study?
balanced appraisal of a study's strengths and weaknesses
(An intellectual critical appraisal involves careful examination of all aspects of a study to judge
the strengths, weaknesses, meaning, and significance of a study.
A. A thorough critical appraisal contains much more than an analysis of the study's internal
validity problems.
C. A critical appraisal points out both the strengths and weaknesses of a study.
D. A simple "inventory" of the study's problems does not constitute a good critique.) A
critical appraisal or critique should be a(n):
A. analysis of a study's internal validity problems.
B. balanced appraisal of a study's strengths and weaknesses.
C. criticism of the researcher's faulty decisions.
D. inventory of problems in the study.
Is the problem sufficiently delimited in scope without being trivial?
Is the problem significant to nursing?
Is there evidence of researcher biases?
Does the purpose narrow and clarify the aim of the study?
, Was the study feasible in terms of funding, expertise, subjects, facility, equipment, and ethical
considerations? What questions would you ask related to the research problem and
purpose?
-Identifies the nature of the problem
-A situation in need of a solution, improvement, or alteration
-Is the problem stated clearly?
-What was conducted to resolve the problem?
-Is the problem of significance to nursing and or healthcare? About the Problem
Statement
-Generated from the problem
-Identifies the specific goal or aim of the study
-Identify, describe, explain, predict a solution
-Includes variables, population, setting About the Purpose of a Study
The Literature Review
(Recognize it, give it a name, and study it ) -Does it demonstrate progressive development of
ideas through previous research?
-Is a theoretical knowledge base developed for the problem and purpose?
-Does the literature review provide a rationale and direction for the study?
-Is a clear, concise summary presented of the current empirical and theoretical knowledge in the
area of study?
About the Literature Review of a Study -Compressed, summary usually in articles
-References should be current and include classics, experts in the field
-Supports the need for the study, gap in the knowledge
-Presents previous work done in the area, builds on previous work
-Needs to critique or evaluate, not just report
-Identifies strengths and weaknesses of previous studies
-Organized logically, objective
-Should include theoretical or research articles, opinion or anecdotal
How about the study framework? -Was the study linked to a larger theoretical nursing or
other conceptual model?
-Is the framework presented with clarity?
-If a map or model is presented, is it adequate to explain the phenomenon of concern?
-Is the framework linked to the research purpose?
-Would another framework fit more logically with the study?
Conceptual / Theoretical Framework -Link needs to be logical
-Permits organization of the study
-Gives direction, provides a context for interpreting findings
-Research question / hypothesis needs to flow from the framework
-Guides the design and methodology
-Most studies not based or linked to a theory or model
-Nursing - humans, environment, nursing & health
-Are the objectives, research questions, or hypotheses expressed clearly?
-Are the objectives, questions, or hypotheses logically linked to the research purpose and
framework?
