The Integrated T3 (Trauma, Training and Treatment) Project will increase access to outpatient trauma treatment through expanding an existing outpatient treatment program. The project will target children and adolescents aged 10–18 who have suffered traumatic events, and who have other co-occurring mental health disorders and/or substance use disorders. Placement will be determined based on the severity of traumatic events—prioritizing those children and youth who are: 1) from military families, 2) at highest risk of substance abuse or dependence, and 3) experiencing problems associated with substance use (e.g., emotional, physical, legal, social familial, academic issues) and who cannot otherwise access such services. The project will offer trauma-focused and trauma treatment services to children, adolescents, and their families/primary caregivers, using a combination of two evidence-based models: Trauma-Focused Cognitive Behavioral Therapy (TF-CBT) and the family-centered Assertive Community Reinforcement Approach (ACRA) model. During the lifetime of the grant, Integrated T3 will serve a minimum of 240 children/adolescents, and will offer framing and technical assistance on trauma-focused treatment services to the 23 providers in the Central Florida Cares Health System’s Managing Entity Network
