Information came from literature reviews; two studies of a Stockholm suburb's experience with juvenile crime and responses to it; observations of several experimental projects in juvenile delinquency prevention; and site visits to the juvenile justice systems in the Soviet Union, Poland, Denmark, and the United States. Findings showed that the delays between the crime and the final disposition are unreasonably long. School and recreation staff are usually the first to become aware of youth problems and generally respond by talking to the youth and the parents. The agencies serving youth are confused regarding their roles, and interagency cooperation is generally nonexistent. Recommended changes include centralizing resources for juvenile delinquency prevention and assigning only one contact person for each juvenile referred to multiple agencies.
