Critical Appraisal Practice Part II Assignment Purpose: Practice appraising the trustworthiness of quantitative research. Appraising evidence in published literature is a multi-step process. This second part of the appraisal process provides a systematic approach to reading and appraising the methods, results, discussion, and conclusions of a research study. Continue this process with the quantitative research study introduced in Week 2 and used in Week 4 of this course. Instructions: Read the sample research study. Accessed the sample research study for this assignment. https://online.pmi.edu/bbcswebdav/pid-12444002-dt-content-rid-216840434_1/xid-216840434_1 Complete the table below based on the information you gather from the research article. In the Rationale sections, be sure to include specific information or examples from the study. Article Section Content Questions Appraisal: Check one box Methods Research Design Is the design selected in alignment with the purpose? Is the design appropriate to reach the stated outcome? Is a control or comparison group used when its use strengthens the validity of the outcome? Are the researchers blind to the assignment of participants (when it makes sense)? Are the participants blind to their assignment (when it makes sense)? Does the design limit the number of extraneous variables? ___ Strength ___Limitation ___Not Evident ___Not Applicable Rationale: Methods Sample Did the authors describe the population that the sample is intended to represent? Was the sampling frame used appropriate for the purpose of the study? Were the inclusion and exclusion criteria clearly described and was it appropriate for the intended outcome? Was the assignment of participants to treatment and control/comparison groups random or nonrandom and was the method appropriate? Was the sample size sufficient to include all applicable variability? Was a sampling calculation discussed? ___ Strength ___Limitation ___Not Evident ___Not Applicable Rationale: Methods Research Protocol Was the protocol for conducting the study described thoroughly and in enough detail? Was the protocol followed appropriate for the purpose? Did the study continue long enough to have valid outcomes? Was the protocol consistently administered to the participants in each group? Did the researchers take steps to control for extraneous variables? Was the protocol ethical and approved by an Institutional Review Board (IRB)? ___ Strength ___Limitation ___Not Evident ___Not Applicable Rationale: Methods Data Collection Were data collection methods appropriate for the intended purpose of the study? Were data collection procedures consistently applied to the participants? Was the validity and reliability of the data collection instrument established at a high enough level? Was the reliability of the data collectors established at a high enough level? ___Strength ___Limitation ___Not Evident ___Not Applicable Rationale: Results Sample Were important demographics of the intervention and control/comparison group similar and if not, did it impact the results? Were treatment and control groups similar at the baseline measurement of the outcome variables and if not, did this difference impact the results? How were eligible participants accounted for throughout the study? Was the discontinuance rate comparable between the treatment and control or comparison group? ___Strength ___Limitation ___Not Evident ___Not Applicable Rationale: Results Data Analysis What did the power analysis indicate? Were data analyzed using an on-protocol or intention to treat analysis or both? If intention to treat analysis was used, what method was used to input missing data? Were the statistical analyses appropriate for the level of data (nominal, ordinal, interval or ratio)? Were the statistical analyses appropriate to test the hypotheses and answer the research questions? ___Strength ___Limitation ___Not Evident ___Not Applicable Rationale: Results Findings Are findings presented relative to each hypothesis and research question? Are findings reported as statistically significant or not significant? When confidence levels are reported, are the upper and lower limits acceptable to implement a change to your practice? Do the findings have practical or clinical significance? ___Strength ___Limitation ___Not Evident ___Not Applicable Rationale: Discussion Did the researchers thoroughly explain their interpretation of the findings? Were the explanations logical? Did the researchers compare their findings to the findings of previous studies and provide a rationale on why they differ? Do the researchers thoroughly identify and discuss the limitations? What are the implications for practice? What future research recommendations are made? ___Strength ___Limitation ___Not Evident ___Not Applicable Rationale: Conclusions Is a conclusion provided for the intended purpose of the study? Do the conclusions logically follow from the findings and interpretation? ___Strength ___Limitation ___Not Evident ___Not Applicable Rationale:
