Although cognitive‐behavioural therapy has demonstrated effectiveness in improving mental health outcomes for sexual minority young people (SMYP), existing interventions are primarily designed and evaluated in Western contexts, and their acceptability and responsiveness to culturally relevant issues in the Chinese contexts is uncertain. This study aimed to address this gap by exploring how a manualised community‐based cognitive‐behavioural intervention (AFFIRM) could be culturally reconsidered for SMYP in Taiwan and Hong Kong and suggest recommendations for future adaptation. Following an empirical, community‐based participatory approach, qualitative data were collected between August and September 2018 through five focus groups with 15 SMYP and 18 frontline practitioners in Taiwan and Hong Kong. Thematic analysis revealed that at the surface structural level, translation and examples, and promotion strategies can be fine‐tuned to better fit the Chinese context. On the deep structural level, self‐differentiation and a pragmatic plan to come out to parents were identified as two concerns of cultural importance for Chinese SMYP. This study exemplifies an empirical, collaborative approach to identifying areas of cultural adaptation for mental health intervention for SMYP in the Chinese cultural milieu. The rationale and strategy for adapting existing intervention protocols to accommodate divergent cultural values are described.
