Two Feathers Substance Abuse Prevention, Treatment, and Aftercare Project - Two Feathers Native American Family Services (TF) Substance Abuse Prevention, Treatment, and Aftercare (SAPTA) program will provide substance use services, improve care coordination, expand culturally appropriate behavioral health service access, and expand youth early intervention strategies for American Indian (AI) youth and families in Humboldt County by scaling current service structures to additional remote locations in the area. The purpose of our TF SAPTA is to reduce the prevalence of substance abuse and decrease the overall use of substances among AI in Humboldt and Del Norte counties by targeting services towards those with the most entrenched cross-generational substance abuse disorders (SAD). The broad system goal is to build a more effective, collaborative, and sustainable structure within a cultural AI framework to address substance use in the local community. TF SAPTA will do this through expanded and improved care coordination, culturally appropriate evidence-based and practice-based behavioral health (BH) service models, and early intervention models for AI youth. The goals are to: 1) develop and expand partnership to develop workforce and increase coordination of substance abuse disorder/BH prevention, treatment, and aftercare services for AI; 2) increase early intervention and overall access to coordinated and effective behavioral health services by streamlining TF referral process and providing services; and 3) provide youth development activities to support prevention of substance use and promote positive Native identity. This work centers a Multi-Tiered Services System that employs a broad range of targeted evidence-based, practice-based, and culturally appropriate interventions based on need and developmentally appropriate interventions based on age, complexity of trauma, and resources. Within the MTSS all levels of providers, partners, community, and youth are trained in appropriate interventions including Attachment Regulation and Competency framework, CRAFFT SAD screener, Adventure Therapy, and several other culturally based frameworks and approaches. Project outcomes will focus on both process and outcomes and will include measures related to collaborations and the products created from them, number of trainings, type of trainings and trainees, service structures and processes, types, and numbers of SAD/BH services provided, and youth prevention services and types as documented through BH clinic data (screens, referrals, services), patient satisfaction, and training logs.
