Introduction: As a medical professor, I am frequently tasked with designing assignments and evaluations for medical college students. One of the recent assignments involved reviewing a case study on stress management for patients with rheumatoid arthritis and analyzing the sampling technique used, concerns about reliability and validity, and any flaws or discrepancies in the study. Additionally, students were required to locate a qualitative study, summarize its findings, and evaluate its trustworthiness based on the four components of credibility, transferability, dependability, and confirmability. The following answers address these questions in detail.
Answer to Question 1:
The sampling technique used in the case study on stress management for patients with rheumatoid arthritis was purposive sampling. The study participants were recruited based on specific criteria such as having a diagnosis of rheumatoid arthritis, being between 18-75 years of age, and experiencing moderate to severe levels of stress. Purposive sampling is a non-probability sampling method where participants are selected based on predetermined criteria. This technique is often used in qualitative research to ensure that the sample is representative of the population being studied.
Answer to Question 2:
Several concerns regarding reliability and validity may arise in this study. One major limitation is the subjective self-report method used to assess stress levels. The participants were asked to rate their stress levels based on a visual analogue scale, which may be subject to response bias. There was also no control group, which makes it challenging to determine whether the results were due to the stress management interventions or other external factors. These limitations may affect the study’s internal validity. Additionally, the sample size was relatively small, which may limit the generalizability of the findings to larger populations.
Answer to Question 3:
There were no significant flaws or discrepancies in the study. The researchers provided a clear overview of the study’s purpose, methodology, and results. They used a mixed-methods approach to collect data, which enhances the study’s validity. The study’s limitations were acknowledged, and the researchers provided recommendations for future research. Overall, the study was well-designed and executed.
Answer to Question 4:
The qualitative study chosen is “Exploring patient and family involvement in the lifecycle of chemotherapy treatment for solid tumors” by Howell et al. (2020). The study aimed to explore patients’ and family members’ experiences and perceptions of chemotherapy treatment for solid tumors and identify ways to enhance their involvement in treatment decision-making. The study involved semi-structured interviews with 32 patients and 14 family members.
Howell et al. (2020) established trustworthiness by addressing the four components of credibility, transferability, dependability, and confirmability. Credibility was established by using member checking and peer debriefing. The researchers also reflected on their biases and preconceptions during data analysis to ensure data accuracy. Transferability was achieved by providing sufficient details on the sample, data collection, and analysis methods, allowing other researchers to assess the study’s applicability to their contexts. Dependability was ensured by providing a clear description of the research process, allowing for the study’s replication to assess the consistency of the findings. Confirmability was established by using an audit trail to document the research process and ensure transparency and accuracy.
Suggested improvements for the study include expanding the sample size to increase diversity and representativeness, employing different data collection methods such as observation, and conducting follow-up interviews to assess any changes in patients’ and family members’ perceptions of treatment over time.
Conclusion:
In summary, the case study on stress management for patients with rheumatoid arthritis used purposive sampling, and concerns about reliability and validity were related to the subjective self-report method used to collect data and the absence of a control group. In contrast, the qualitative study by Howell et al. (2020) established trustworthiness by addressing all four components of credibility, transferability, dependability, and confirmability. However, the study could be improved by expanding the sample size, using different data collection methods, and conducting follow-up interviews. Overall, addressing these issues is critical in ensuring the accuracy and applicability of research findings in healthcare.
