TL;DR

This video discusses the common criticisms of qualitative research in health sciences, the established techniques that assure rigor, and the important aspects of reporting a qualitative study.

Transcript

hi I'm Leslie curry from the Yale School of Public Health welcome back to our series on qualitative research methods this module addresses evaluating the rigor of qualitative research to remind us of the goal of this series we're intending to enhance our capacity to conceptualize design and conduct qualitative research in the health sciences there ...

Questions & Answers

Q: What are the common criticisms of qualitative research in health sciences?

Common criticisms of qualitative research in health sciences are lack of reproducibility, lack of generalizability, and potential researcher bias. Qualitative methods are not as directly reproducible as quantitative methods, as the analysis process is not as structured and standardized. Due to purposeful sampling and small sample sizes, qualitative findings cannot be reliably generalized to larger populations. Additionally, there is the potential for researcher bias in data collection, analysis, and interpretation.

Q: How can scientific rigor be assured in qualitative research?

Scientific rigor in qualitative research can be assured by following established techniques and principles. There are resources available, such as seminal papers and the korok checklist, that provide guidelines for ensuring rigor. These include being explicit about the rationale for using qualitative methods, detailing the sampling strategy and achieving theoretical saturation, providing interview guides and codes used in analysis, documenting systematic processes, and considering participant confirmation of findings.

Q: What aspects of a qualitative study should be included in the reporting?

The reporting of a qualitative study should include several key aspects. Firstly, the rationale for choosing a qualitative approach and the specific method used (e.g., focus group study) should be explained. The sampling strategy, including selection criteria and the principle of saturation, should be detailed. The interview guides used in data collection should be included as appendices, along with information about the analysis process, such as the number of coders, code structure, use of software, and handling of diverging evidence. Evidence of systematic processes, such as participant confirmation and an audit trail, should also be provided.

Q: What are the established techniques and resources for ensuring scientific rigor in qualitative research?

There are several established techniques and resources for ensuring scientific rigor in qualitative research. Seminal papers, such as Mazen Pope's paper in the BMJ, and papers from organizations like NIH and The Lancet, provide guidelines for qualitative research quality. The korok checklist is a valuable tool for researchers reporting interview and focus group studies. These resources emphasize the importance of clear rationale, defined methodological approaches, sampling strategy, detailed data collection and analysis methods, and systematic processes. By following these guidelines, researchers can address the inherent limitations of qualitative methods and ensure the rigor of their research.

Summary & Key Takeaways

• Qualitative research in health sciences is increasingly adopted but faces common criticisms of lack of reproducibility, generalizability, and potential researcher bias.

• There are established techniques and resources that assure scientific rigor in qualitative research, such as standards defined in seminal papers and tools like the korok checklist.

• Reporting a qualitative study should include clear rationale, sampling strategy, details of data collection and analysis, and evidence of systematic processes followed.
