Family Behavior Therapy (FBT) is a scientifically supported intervention to assist optimization in mental health. The development of FBT was originally funded by the National Institute on Drug Abuse (NIDA) & National Institute of Mental Health (NIMH). This approach is one of the only scientifically supported approaches to demonstrate improved outcomes in both adolescent and adult substance abuse. The approach is currently listed in various clearinghouses, including SAMHSA's National Registry of Evidence-based Programs and Practices, California Evidence-Based Clearinghouse for Child Welfare, and Clearinghouse for Military Family Readiness. Ratings from anonymous reviewers in these clearinghouses are relatively high for both dissemination and research. In a review by National Institute on Alcohol Abuse & Alcoholism (NIAAA), FBT was listed as one of the several "evidence-based, developmentally sensitive approaches emerging for addressing alcohol, nicotine, and other drug use problems among adolescents." In a meta-analysis study, FBT was one of two intervention approaches found to demonstrate large effect sizes across substance abuse, internalizing, and externalizing problems in dually diagnosed youth.
