The document is intended as a practical reference to allow interested persons, agencies, and communities to make an informed decision about a program's appropriateness for their local situation, needs, and available resources. An introduction notes that demand for effective violence and crime prevention programs has never been greater, but most programs being used have not been evaluated. Therefore, a collaborative effort was conducted to identify 10 violence prevention programs that met a high scientific standard of program effectiveness, based on their strong research design, data indicating significant deterrent effects, sustained effects, and multiple site replication. The project included plans for a technical assistance and monitoring component. Multidimensional Treatment Foster Care (MTFC) is a cost-effective alternative to group or residential treatment, incarceration, and hospitalization for adolescents who have problems with chronic antisocial behavior, emotional disturbance, and juvenile delinquency. The program recruits, trains, and closely supervises community families to provide adolescents with histories of chronic and severe criminal behavior with treatment and intensive supervision at home, in school, and in the community. The youth's biological or adoptive family receives family therapy. Youth participate in a structured daily behavior management program in the foster home and receive individual, skill-focused therapy. The program reduces incarceration, subsequent arrests, running away, and drug use. Tables, figure, appended program materials, reference notes, and 57 references
