Children's Research Triangle's (CRT) Trauma Treatment Program (TTP) is an assessment-driven, trauma-informed intervention program based in Chicago, Illinois. The TTP will increase the availability of trauma-informed therapeutic services for children and adolescents ages 0 to 18 years by implementing evidence-based interventions in under-resourced communities. The TTP follows a comprehensive screening, assessment, and treatment process, which includes foundational material from the NCTSN's 2012 Breakthrough Series Collaborative, Improving Comprehensive Assessments and Case Formulations by Implementing the NCTSN Core Curriculum. A high standard of care will be ensured by ongoing training, consultation, and reflective supervision for TTP staff and partner site staff, as well as continuous input from the consumer groups, the Youth Advisory Board and the Parent Network Committee, to provide consumer voice in the development and implementation of services. The TTP employs several Evidence-Based Practices, including Child-Parent Psychotherapy (CPP), Trauma-Focused Cognitive Behavioral Therapy (TF-CBT), and Structured Psychotherapy for Adolescents Responding to Chronic Stress (SPARCS). During each of the five years of funding, 400 children and adolescents will be screened for traumatic histories; 225 will undergo a systematic trauma assessment; 60 will participate in TTP trauma-focused interventions; 60 will participate in Youth Trauma Workshops; 100 community members will receive training about the mental health impact of childhood trauma, and 50 community members will receive training on prevention/mental health promotion topics related to childhood trauma. Taking into account overlap in screening, assessment, and treatment, CRT will provide direct services to a minimum of 3,050 individuals over the five years.
