Historical and current trauma places Indigenous peoples at increased health risk relative to others, and negatively influences CI self-management. The Apsáalooke Nation and Montana State University worked together to develop and implement a trauma-informed CI self-management program to improve the Apsáalooke community's health. This paper describes the origins and development of the trauma-informed components of the program. Using community stories and a literature review of trauma-informed interventions, partners co-developed culturally consonant trauma materials and activities grounded in community values and spirituality. Trauma-informed content was woven throughout three intervention gatherings and was the central focus of the gathering, Daasachchuchik ('Strong Heart'). Apsáalooke ancestors survived because of their cultural strengths and resilience; these cultural roots continue to be essential to healing from historical and current trauma.en-USArticle
