To develop a cultural and trauma-informed mental health self-management program for immigrant Latina survivors of adverse childhood experiences with depression or anxiety symptoms. Guided by Barrera's five-stage process for cultural adaptation, we collaborated with multiple stakeholders including clinical psychologists, community health workers, and Latina immigrant women with a history of adverse childhood experiences and depression or anxiety to transform a chronic disease self-management program to be trauma informed, culturally appropriate, and focus on self-management of depression and anxiety symptoms. Adaptations included translating program materials to Spanish, education on how early life adversity and trauma may impact mental health, virtual delivery, more frequent and shorter sessions, and addition of graphics and written prompts in workbook materials. For the facilitator's manual, culturally relevant vignettes and guidance were added to guide participants through activities and adapt sessions based on participant needs. Barrera's five-stage process was useful for adapting a program to be both trauma and culturally informed for an underserved population disproportionately affected by trauma and limited access to mental health services. The adaptation demonstrated acceptability with Latina immigrant women and the promise of utilizing unlicensed personnel and technology for increasing the reach of mental health support.
