Switchboard of Miami Inc. proposes to implement and sustain a collaborative trauma initiative: PACTT (Providing Adolescents and Children with Trauma-focused Treatment). This initiative was specifically data-driven to identify and address well-documented, unmet needs of trauma-affected children, adolescents and families, which are identified as disparity subpopulations. The other disparity populations PACTT will reach are a large domestic violence shelter and a juvenile justice services department that have specifically requested trauma services to address high unmet needs and military families. While Switchboard has an existing TF-CBT program, it is over-capacity, as is the other major trauma services provider in our large county. PACTT is guided by two overarching goals and many objectives too numerous to mention in the constraints of this abstract. Services Goal 1: Reduce the unmet need for trauma-focused services for Miami-Dade County children, adolescents, and their families; and infrastructure; Goal 2: Strengthen the capacity of the child and youth service delivery system to deliver high quality, evidence-based, trauma-focused care. PACTT proposes to screen (n=1800) and assess (n=1118) for trauma and provide evidence-based TF-CBT services to 475 of these children, youth and families (100 per year minus start-up) whose screening and assessment document internalizing problems, such as depression or anxiety, and/or externalizing problems, like aggression, conduct problems, and oppositional or defiant behavior. Moreover, PACTT will enhance system capacity to become better trauma-informed by training 1350 or more local health and human service professionals and will build trauma-focused infrastructure through creation of an Initial Advisory Leadership Council. The University of Miami Comprehensive Drug Research Center (CDRC), a nationally and internationally recognized research team, will lead the process and outcome evaluation.
