IDCC Child and Adolescent Trauma (CATS) - The Interborough Developmental & Consultation Center, Inc. IDCC Child and Adolescent Trauma CATS project will provide evidence-based, trauma focused direct services through a strengthened organizational and clinical infrastructure to 1800 unduplicated diverse children and adolescents ages 0 -21, who have experienced trauma, in Brooklyn, New York most populous borough 200 unduplicated in year 1; 400 unduplicated per year after. At IDCC, 48% of the 2,796 diverse children, ages 0-21 and living in Brooklyn, who received mental health treatment in 2020 throughout its network of mental health, substance abuse, and school-based clinics reported at least one adverse childhood event or trauma experience. Almost 2/3 of children self-identify as Black, Latinx, or Asian and nearly half live in families with income below the poverty level. To immediately impact direct trauma-focused evidence-based treatment services, IDCC will build on its practice of implementation-based science-to-service training and robust continuum of clinical support services to address complex trauma in a culturally appropriate manner. Two Senior Clinical Leads will support a newly developed, agency-wide Trauma Team (TT) whose members have advanced clinical expertise, reflect the children's cultural and linguistic diversity, and provide direct technical assistance to staff as they implement EBPs. CATS will provide agency-wide training on EBPs recognized as effective for children with trauma and will utilize the TT and its well-developed supervisory structure to immediately integrate these EBPs with fidelity into practice so children receive immediate and culturally appropriate treatment. The Project Director and SCLs will organize and co-lead EBP training for 548 Master level clinicians, 18 PhD level clinicians, 11 care management staff, and 14 post-graduate degree-seeking interns providing services throughout its network of 8 mental health clinics (3 focused on substance use disorders) and 40 school-based clinics. SAMHSA and the NCTSN have noted that organizational-wide trauma-informed transformation requires core staff competencies. Through CATS, IDCC will build those competencies and enhance trauma practice skills. Goal 1: IDCC will train 95% of its staff in clinic, school, care management and post-graduate internship positions in these EBPs: Trauma-Focused Cognitive Behavioral Therapy (TF-CBT), Dialectical Behavioral Therapy (DBT), Attachment, Self-Regulation, and Competency (ARC), Cognitive Behavioral Intervention for Trauma in Schools (CBITS); Goal 2: 100% of children served by IDCC receive immediate and effective screening, treatment, care management by staff who understand trauma, incorporate EBPs and implement culturally appropriate care into their treatment practice; Goal 3: Increase awareness, knowledge and sensitivity about the impact and signs of trauma by sharing information with school staff, community partners, parents/caregivers and children through presentations and workshops. CATS will ensure agency-wide staff provides immediate, culturally congruent and appropriate trauma-informed treatment throughout our extensive network of direct services from outreach through treatment.
