The NNCTC will pursue two goals: 1. Provide culturally centered, evidence-based, trauma-informed training and technical assistance (TTA) along the full spectrum of needs/readiness in Tribal communities and across all types of Tribal child-serving systems; and 2. Enhance our center infrastructure to increase scale of training/education dissemination, to fill gaps in product offerings, to broaden access to resources, and to promote data-driven program improvements. Our project’s population of focus consists of American Indian and Alaska Native (AI/AN) children and youth at a national level, both in Tribal reservation communities and in urban areas. This population is disproportionately affected by trauma exposure and disproportionately lacking in access to effective mental health services. Our project seeks to address these disproportions by supporting youth-serving agencies in Tribal communities as they troubleshoot their resource limitations. Under goal 1, we will pursue objectives including supporting 2 multi-year Tribal community-wide resilience projects and 4 agency/system-wide resilience projects; supporting the implementation of our cultural adaptations of evidence-based clinical interventions in 10 schools or other settings; providing foundational trauma and resilience trainings to 20 AI/AN child-serving organizations; providing trainings in adapted NCTSN curricula to 10 AI/AN child-serving organizations; and providing issue-focused TTA to 10 Tribes or agencies. Under goal 2, we will pursue objectives including redevelopment of the NNCTC website to create a virtual hub for Trauma trauma-focused TTA resources; the building of a national listserv of Tribal stakeholders and trauma professionals; adaptation of 3 commonly requested foundational trainings for self-paced virtual platform delivery; development of a series of courses constituting a University of Montana Trauma Certificate program; the convening of Youth Advisory, Parent/Family Advisory, and Cultural Adaptation committees to guide programming; cultural and classroom-based adaptation of a trauma-informed systems framework; cultural adaptation of a group-based trauma treatment model for elementary schools; development of a family-driven Wraparound services curriculum; and process and outcome evaluation of the project. Across virtual and in-person TTA activities we expect to train and/or provide TA to approximately 1,800 AI/AN-child-serving professionals and Tribal community members annually and 9,000 over the five years of the funding period.
