Wicasa Was'aka: restoring the traditional strength of American Indian boys and men.

We examined health disparities among American Indian men and boys within the framework of historical trauma, which incorporates the historical context of collective massive group trauma across generations. We reviewed the impact of collective traumatic experiences among Lakota men, who have faced cross-generational challenges to enacting traditional tribal roles.We describe historical trauma–informed interventions used with two tribal groups: Lakota men and Southwestern American Indian boys. These two interventions represent novel approaches to addressing historical trauma and the health disparities that American Indians face.We offer public health implications and recommendations for strategies to use in the planning and implementation of policy, research, and program development with American Indian boys and men.
