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. PATHS is a comprehensive program for promoting emotional and social competencies and reducing aggression and behavior problems in elementary school children while simultaneously enhancing the educational process in the classroom. Educators and counselors use the curriculum in a multi-year, universal prevention model. They teach the curriculum 3 times per week for at least 20-30 minutes per day. Information and activities are also included for use with parents. The PATHS program improves protective factors and reduces behavioral risk factors.
