1. This document provides guidelines for critically appraising a quantitative research study and writing an assignment on it. Students are to select a study, preferably from a nursing journal, and critically evaluate it using the provided criteria. 2. The evaluation should address the research problem, literature review, framework, objectives, variables, methodology, measurements, data collection/analysis, results, and implications for nursing practice. A rubric is provided to guide the assignment. 3. Students will present their critique to the class, discussing aspects of the evaluation. The goal is to help students understand how to conduct a literature review and evidence-based practice, as well as gain knowledge from nursing research.

Appraisal of a Quantitative Study Assignment Guideline and Rubric The goals of this
assignment are to: 1. Assist students in understanding the basic process of conducting a
literature review/critical appraisal. 2. Assist students in understanding the beginning
process of conducting an evidence-based practice review. 3. Provide students with the
beginnings of scientifically based knowledge on a selected procedure/topic related to
nursing research. Steps of the process: 1. Select a topic with instructor’s approval.
Important because some articles that have been shown to me are not research quantitative
nor qualitative research studies that have come from refereed journals. Article can be
quantitative or qualitative and preferably from a nursing research journal. (Please submit
article to me by end of the day on Monday because I must critique it in order to be able to
evaluate your critique.) 2. Appraise the article critically using the guidelines provided in
Chapter 12. This is the information provided in the syllabus.. 3. Prepare a presentation to
facilitate where a/the group member(s) discuss aspects of the critique. (See
guidelines/questions below.) Power point is suggested because it may provide creativity
and generate audience interest. Information to include in the report (see examples on pages
433-442) Research Problem and Purpose Why is the problem significant to nursing? • Will
the study problem and purpose generate or refine knowledge for nursing practice?
Literature Review • How current is the literature review? • Does the literature review
provide rationale and direction for the study? • Is a clear, concise summary presented of the
current empirical and theoretical knowledge in the area of study? Study Framework • Is the
framework/theoretical basis presented with clarity? • If a map or model is presented, is it
adequate to explain the phenomenon of concern? • If a proposition from a theory is tested,
is the proposition clearly identified and linked to the study hypotheses? Research

2. Objectives, Questions, or Hypotheses • Are the objectives, questions, or hypotheses
expressed clearly? • Discussion: Critical Appraisal of a Quantitative Study Assignment
GuidelineAre the objectives, questions, or hypotheses logically linked to the research
purpose and framework? • Are the research objectives, questions, or hypotheses linked to
concepts and relationships from the framework? 1 Variables • Do the variables reflect the
concepts identified in the framework? • Are the variables clearly defined? • Is the
conceptual definition of a variable consistent with the operational definition?
Method/Design . What type of research is it? Explain. • How were study subjects selected? •
Are any subjects excluded from the study based on age, socioeconomic status, or race,
without a sound rationale? • If more than one group is used, do the groups appear
equivalent? • Are the rights of human subjects protected? • Is the setting used in the study
typical of clinical settings? Measurements What are the instruments that were used to
measure variables and if they are scales and questionnaires did the investigator(s) clearly
describe them, especially the reliability/validity of the instruments? If data were collected
by observation as in qualitative studies are the phenomena to be observed clearly identified
and defined? Is interrater and intrarater reliability described? Are the techniques for
recording observations described? Interviews Do the interview questions address concerns
expressed in the research problem? Are the interview questions relevant for the research
purpose and objectives, questions, or hypotheses? Physiological Measures • Are the
physiological measures or instruments clearly described? Are the methods for recording
data from the physiological measures clearly described? • Data Collection and Analysis • Is
the data collection process clearly described? • Is the training of data collectors clearly
described and adequate? Are the results presented in an understandable way?
Interpretation of Findings • • • Are findings discussed in relation to each objective, question,
or hypothesis? Are the findings clinically significant? Do you believe that there are
limitations that the investigator(s) did not identify? Evaluation • What do you determine
are the major strengths/weaknesses of the study? • To what populations can the findings be
generalized? • What questions emerge from the findings, and are these identified by the
researcher? • What future research can be envisioned? Can the study be replicated by other
researchers? 2 • How do findings inform your practice as a nurse? • When the findings are
examined based on previous studies, what is now known and not known about the
phenomenon under study? That is, are the findings consistent with those from previous
studies? Does the author indicate the implication of the findings for practice? What are the
implications of the findings for nursing practice? • 3 NURS 400 – INTRODUCTION TO
