To assess concept saturation.
Qualitative sample sizes should be large enough to obtain enough data to sufficiently describe the phenomenon of interest and address the research questions. The prevailing concept for sample size in qualitative studies is saturation Saturation is closely tied to a specific methodology and the term is inconsistently applied. We propose the concept information power to guide adequate sample size for qualitative studies. How to choose the sample size in qualitative research and how to c.
