Student’s Comments

Comprehensively address the critique questions and provide examples when appropriate. Do not copy and paste from the article.

Title, Introduction, Statement of the problem

1. Does the title succinctly suggesting key variables and the study population?

2. Is the problem stated unambiguously, and is it easy to identify?

3. Does the problem statement build a cogent, persuasive argument for the new study?

4. Does the problem have significance for nursing?

Hypotheses or research questions

1. Are research questions and/or hypotheses explicitly stated? If not, is their absence justified? Can you infer the research question from the text? If so, what is it?

2. Are questions and hypotheses appropriately worded, with clear specification of key variables and the study population?

3. Are the questions/hypotheses consistent with the literature review and the conceptual framework?

Literature Review

1. Is the literature review up to date and based mainly on primary sources?

2. Does the review provide a state-of-the-art synthesis of evidence on the problem?

3. Does the literature review provide a sound basis for the new study?

Method, Protection of human rights

1. Were appropriate procedures used to safeguard the rights of study participants? Was the study externally reviewed by an IRB/ethics review board?

2. Was the study designed to minimize risks and maximize benefits to participants?

1.

Research Design

1. Was the most rigorous possible design used, given the study purpose?

2. Were appropriate comparisons made to enhance interpretability of the findings?

3. Was the number of data collection points appropriate?

4. Did the design minimize biases and threats to the internal, construct, and external validity of the study (e.g., was blinding used, was attrition minimized)?

Population and Sample

1. Is the population described? Is the sample described in sufficient detail?

2. Was the best possible sampling design used to enhance the sample’s representativeness? Were sampling biases minimized?

3. Was the sample size adequate? Was a power analysis used to estimate sample size needs?

Data Collection and Measurement

1. Are the operational and conceptual definitions congruent?

2. Were key variables operationalized using the best possible method (e.g., interviews, observations, and so on) and with adequate justification?

3. Are specific instruments adequately described and were they good choices, given the study purpose, variables being studied, and the study population?

4. Does the report provide evidence that the data collection methods yielded data that were reliable and valid?

Procedures

1. If there was an intervention, is it adequately described, and was it rigorously developed and implemented? Did most participants allocated to the intervention group actually receive it? Is there evidence of intervention fidelity?

2. Were data collected in a manner that minimized bias? Were the staff who collected data appropriately trained?

Results, Data Analysis

1. Were analyses undertaken to address each research question or test each hypothesis?

2. Were appropriate statistical methods used, given the level of measurement of the variables, number of groups being compared, and assumptions of the tests?

3. Was the most powerful analytic method used (e.g., did the analysis help to control for confounding variables)?

4. Were Type I and Type II errors avoided or minimized?

5. Were problems of missing values evaluated and adequately addressed?

6. Is information about statistical significance presented? Is information about effect size and precision of estimates (confidence intervals) presented?

2 Are interpretations well-founded and consistent with the study’s limitations?

3. Does the report address the issue of the generalizability of the findings?

4. Do the researchers discuss the implications of the study for clinical practice or further research—and are those implications reasonable and complete?

Researcher Credibility

1. Do the researchers’ clinical, substantive, or methodologic qualifications and experience enhance confidence in the findings and their interpretation?

Summary Assessment

2. Despite any limitations, do the study findings appear to be valid—do you have confidence in the truth value of the results?
