Less is More? Review and Recommendations for Qualitative Sampling Strategy using the S.C.A.D.E Approach.

The determination of sample size in qualitative research introduces a unique and multifaceted challenge, setting it apart from the more structured methodology of quantitative research. Contrary to sampling methods in quantitative research, which primarily aim to secure random and statistically representative samples that facilitate the generalisation of findings to broader populations, sampling in qualitative research requires a distinct set of considerations in its pursuit of a deeper understanding of specific phenomena. The objective of this editorial is to provide qualitative researchers with clear and foundational guidance for effectively communicating the methodological aspects of their research papers, particularly pertaining to sample size justification. Building on this, we present S.C.A.D.E, an acronym comprising five key actionable elements--Selecting, Clarifying, Aligning, Deploying and Evaluating--to guide researchers in determining the appropriate sample size and ensuring that data saturation is achieved as they plan their qualitative exploration.
