The report notes that juvenile delinquency is a major social problem with burdensome economic costs. Over 40 percent of arrests for the seven major Index crimes are of youths under 18 years of age. Shifts in juvenile justice philosophy over the years and the goals of prevention are described. Using research findings by the National Center for the Assessment of Delinquent Behavior, the report illustrates a general model of delinquency which integrates control and cultural deviance theories and includes the following general prevention strategies: (1) role development and power enhancement, (2) social network development, (5) education/skill development, (4) clarity and consistency of social expectations, (4) criminal influence reduction, and (6) deterrence. The report describes a project which could be designed to study both individual and combined interventions, ordered according to the institution targeted (i.e., the family, school, peers, work setting, and community). Finally, the report suggests a research design for the evaluation of those delinquency prevention programs that include elements of the interventions outlined in the report. Over 100 references are appended and diagrams are included.
