Introduction:
In this assignment, we will be reviewing three research articles with different methodologies. The first one is a quantitative study on social media literacy intervention to reduce risk factors for eating disorders. The second one is a qualitative study on wives’ experiences of living with active duty Marine husbands with PTSD. The third one is a systematic review article on the role of fruits and vegetables in adolescent cardiovascular health. We will be answering ten questions based on these three articles, focusing on research design, sampling strategy, measurement strategy, data collection methods, and evidence-based practice synthesis.
Answer:
1. The study design for the quantitative article “A pilot evaluation of a social media literacy intervention to reduce risk factors for eating disorders” was a randomized controlled trial. Yes, the study design reflected the purpose of the study, which was to evaluate the effectiveness of a social media literacy intervention in reducing the risk factors for eating disorders.
2. The researchers did discuss the sampling method, which was a convenience sample. Although a convenience sample is not representative of the population, it was appropriate for the design chosen as the study was a pilot evaluation.
3. The researchers conducted a power analysis as a statistical tool to determine the sample size needed to detect a significant effect, with an ideal power value of 0.8. The researchers conducted the power analysis, and the power value was found to be 0.59, which is lower than the ideal power value.
4. The validity and reliability of the measurement tools were reported to be satisfactory. The instruments were reliable and valid, but they were not specifically validated for the target population.
5. The researchers have reported the “trustworthiness” for qualitative studies. The researchers followed the criteria of credibility, transferability, dependability, and confirmability to ensure the trustworthiness of the findings. However, some aspects, such as the sample size, could have increased the credibility of the study.
6. The researchers discussed the sampling method in the qualitative article “We walk on eggshells”: A phenomenological inquiry of wives’ experiences of living with active duty Marine husbands with PTSD. The sampling method was purposive sampling, which was appropriate for the research approach/design chosen as the study aimed to explore the experiences of a specific group of people.
7. The researcher used in-depth semi-structured interviews for data collection. The researcher maintained ethics during participant selection and data collection by obtaining written informed consent, ensuring voluntary participation, ensuring confidentiality and anonymity, and providing debriefing sessions.
8. Four reviewers examined the articles in the systematic review article “Role of fruits and vegetables in adolescent cardiovascular health: a systematic review.” No discrepancies were reported among the reviewers, and they solved any disagreements through discussion. The categories evaluated by the reviewers matched the purpose of the review.
9. The reviewers ensured the quality of the articles by using the Joanna Briggs Institute Critical Appraisal tool. They reported the potential biases, such as publication bias, selection bias, and performance bias. The reviewers also assessed the risk of bias of the included studies.
10. The authors’ conclusion and recommendation of the systematic review correlate with the results and discussion details presented. The reviewers concluded that the intake of fruits and vegetables among adolescents was associated with cardiovascular health benefits. The authors’ recommendation was to promote and reinforce the intake of fruits and vegetables in this age group.
