The article discusses the sample size policy for qualitative studies using in-depth interviews, particularly in the context of the Archives of Sexual Behavior. It highlights the importance of understanding the concept of saturation, which is the point at which data collection no longer yields new insights. The policy recommends a minimum sample size of 25-30 participants for grounded theory studies using in-depth interviews, aiming to ensure thorough examination of characteristics, clarity in conceptual relationships, and exploration of negative cases. This recommendation is intended to provide practical guidance without rigidly quantifying sample size, as the debates on this matter are complex and context-dependent. The policy does not apply to other qualitative methodologies or phenomenological studies.The article discusses the sample size policy for qualitative studies using in-depth interviews, particularly in the context of the Archives of Sexual Behavior.
