The summary offers an overview of the conclusions and recommendations derived from a comparison of two programs for juvenile delinquents, a traditional institutional approach (DOC) and the Unified Delinquency Intervention Services (UDIS) designed to deal with boys effectively without institutionalization. Sections cover the following topics (sample subtopics are in parentheses): the suppression effect of correctional intervention (consistency of the findings with other research, explanation of the suppression effect, and the reasons why UDIS and DOC produced dramatic drops in recidivism); UDIS versus institutionalization (recidivism and costs); and the UDIS approach (individualized programing, short-term programing, the least drastic alternative principle, and protection of the public). It is concluded that there are three main lines of objection to resorting to UDIS or DOC before a long record of arrests or earlier than the age of 16: costs, the problem of false-positives, and generalized antagonism to intervention.
