The study was designed to assess the extent to which the JEP would effect the recidivism rates of juvenile and young adult offenders. From June to October 1980, 53 junveniles from 3 Kansas counties who were on probation participated in the initial data collection. Of these, 36 completed the followup evaluation conducted from January to April 1981. All subjects were males between 14 and 19 years old. Self-reported or criminal offenses committed during the premeasure and followup periods were measured in experimental and control groups to which subjects were randomly assigned. No significant differences in the mean number of offenses are found between the two groups. Prior conflicting results regarding this type of intervention may be because youths categorized as more delinquent and youths categorized as less delinquent were affected differently by the program. 2 tables, 2 figures, and 19 references.
