Serving Children and Adults in Need Inc. (SCAN) is proposing to implement its Border Traumatic Stress Response Center to increase access and the quality of effective trauma-focused treatment and service system in Webb County for children and adolescents, and their families who have experienced or witnessed a traumatic event. The project will provide access to all children and their families in Webb County, especially children living in underserved areas, adolescents with co-occurring trauma and substance use disorder and children of parents who are receiving substance use disorder treatment services. The project will serve a total of 750 children and their families (150 annually) for the duration of the project. SCAN will continue to foster the development of trauma-informed systems of care in Webb County through ongoing collaborations with community partners and NCTSN Category II sites. The projects goals are to: 1) Provide outreach and engagement strategies to increase access to and participation in trauma treatment and prevention services for children, adolescents, and their families who have experienced a traumatic event; 2) Provide a full continuum of evidence-based, trauma-focused, mental disorder treatment and services, including screening, assessment, care management, therapy, and prevention for diverse and at-risk children and adolescents; 3) Foster trauma-informed systems of care at local, regional, and state levels through education in trauma-informed practices for staff in child protective services, the foster care system, the juvenile justice system, and using SCAN's expertise and Network resources; 4) Collaborate with NCTSI Category II Treatment and Service Adaptation (TSA) Centers to develop, advance, or adapt interventions to improve engagement and outcomes for traumatized youth; 5) Implement a project evaluation, including process and outcomes evaluation, to be submitted to SAMHSA by the end of the project period; and 6) Staff will deliver culturally and linguistically competent evidence-based interventions with a high degree of fidelity. The project will collaborate with NCTSN TSA and CTS Centers on the development and enhancement of interventions for traumatized youth to make them more culturally and linguistically relevant. The project will utilize the following evidence-based practices: Trauma-Focused Cognitive Behavioral Therapy (TF-CBT); Trauma Systems Therapy for Substance Abuse (TST-SA); Parent Child Interaction Therapy (PCIT) and Child-Adult Relationship Enhancement (CARE).
