The National Native Children's Trauma Center (NNCTC) will work in collaboration with Indian Health Service (IHS) and other providers in tribal communities across the country to utilize evidence-based, culturally appropriate, trauma-informed interventions for American Indian/Alaska Native (AIAN) children, youth, and military families who experience disproportionate violence, grief, and/or poverty; and childhood, historical, and/or intergenerational trauma. The center will serve as a national leader in trauma intervention training and workforce development. The four goals are to: 1) train IHS clinicians in two evidence-based trauma treatments: Child and Family Traumatic Stress Intervention (CFTSI) and Trauma-Focused Cognitive Behavioral Therapy (TF-CBT); 2) equip schools to provide trauma-focused interventions and services; 3) enhance trauma-informed child welfare practices and replicate them in four IHS service areas; 4) engage members of the center's National Expert Advisory Council (NEAC) as well as traditional healers, council leaders, and community members to ensure high fidelity replication of evidence-based practices; 5) use the Warrior Society Model to improve natural supports for Native children whose parents are or were deployed; and 6) increase the number of tribal partnerships with the center. The primary focus will be on infrastructure development through training and technical assistance of behavioral health. Over the four years of this grant, training will be delivered to 360 adult providers serving a total of 34,800 children and youth with trauma.
