This paper presents a method for assessing and reporting thematic saturation in qualitative research, addressing the limitations of existing approaches. The method, based on the principle of saturation, includes three key elements: Base Size, Run Length, and New Information Threshold. Base Size refers to the number of data collection events (interviews) used as a denominator for calculating the total number of unique themes. Run Length is the number of consecutive interviews used to calculate new information. New Information Threshold is the level of new information that indicates saturation, with options of ≤5% and 0%. The method is validated through bootstrapping techniques on three existing qualitative datasets, demonstrating its feasibility and consistency with earlier studies. The approach offers flexibility in assessing saturation, allowing researchers to choose different levels of rigor and confidence. The paper concludes by highlighting the method's utility and potential for further empirical testing.This paper presents a method for assessing and reporting thematic saturation in qualitative research, addressing the limitations of existing approaches.
