摘要：Reaching a saturation point in thematic analysis is important to validity in qualitative studies, yet the process of achieving saturation is often left ambiguous. The lack of information about the process creates uncertainty in the timing of recruitment closure. This exploratory study was conducted to demonstrate a rigorous approach to reaching saturation through two-stage establishment of a codebook used for thematic analysis. The codebook development involved inductive analysis with six interviews, followed by a refinement of the coding system by applying them to an additional 33 interviews. These findings are discussed in relation to plausible pattern in code occurrence rate and suggested sample sizes for thematic analysis.
