The study reviewed 58 qualitative appraisal guidelines and identified 12 core criteria that were consistently valued across different health science disciplines. These included elements such as a clear research question, theoretical framework, methodology, sampling, data analysis, reflexivity, credibility, and ethics. While broad agreement existed on the importance of these criteria, differences emerged in how they were defined and applied across disciplines. Overall, the paper highlights both the potential for consensus in qualitative appraisal and the need for flexibility when evaluating research quality.
