The effects of culturally adapted expressive writing interventions on depressive and anxiety symptoms among Chinese American breast cancer survivors: A randomized controlled trial

Abstract

BackgroundExpressive writing interventions confer mental health benefits for non-Hispanic Whites. However, research is lacking in adapting this paradigm for minoritized groups. This study evaluated the impacts of two culturally adapted expressive writing interventions on depressive and anxiety symptoms and potential mediators (perceived stress and intrusive thoughts) among Chinese American breast cancer survivors (CABCS). Methods and Results: CABCS (N = 136) were randomly assigned to one of three conditions to write three weekly essays: enhanced self-regulation condition (ESR) to write about stress and coping (Week 1), deepest feelings (Week 2), and finding benefits (Week 3); self-regulation condition (SR) to write about deepest feelings (Week 1), stress and coping (Week 2), and finding benefits (Week 3); and control condition to write about facts relevant to their cancer experience (Weeks 1–3). Compared with the control condition, the ESR but not SR, reduced depressive and anxiety symptoms at all follow-up time points (1, 3, and 6-months) through reductions in perceived stress. Conclusion: A cultural adaptation altering the order of expressive writing prompts resulted in the greatest benefit for CABCS’ depressive and anxiety symptoms. Research testing both the content and ordering of components may be vital to advance cultural adaptation science and optimize intervention efficacy.Clinical trial registration number: NCT02946619.
