Walker, Robert; Logan, TK; Cole, Jennifer; Scrivner, Allison

The KTOS assessment is an intake instrument developed by the Center on Drug and Alcohol Research Behavioral Health Outcome (CDAR BHOS) team in collaboration with the Kentucky Department of Behavioral Health, Developmental and Intellectual Disabilities (DBHDID) to: (1) identify drug use trends in the state over time, (2) to identify substance use-related co-morbidities, and (3) to monitor substance abuse treatment outcomes within the context of the state specific economic and health-related concerns. KTOS was designed to serve as a screening and assessment tool for individuals seeking drug treatment of all types and can be used during program admission. The KTOS assessment is made up of five core components (substance use, mental health, victimization and trauma, criminal justice system involvement, and quality of life) and three supplemental components (health and stress-related health consequences, economic and living circumstances, and recovery supports). It takes approximately 35 minutes to administer the KTOS assessment.
