The five primary goals of this project were to obtain individual and environmental data on 75 youth offenders; to relate these data to recidivism; to link these factors to prosocial change; to examine the influence of mentor and probation officer factors in intervention success; and to disseminate the study findings. The preliminary findings provide support for the effectiveness of community-based interventions in reducing youth offenders' recidivism. Findings also show the importance of factors related to a youth's mindset of "readiness-for-change" in responding and committing to intervention measures. An important feature of readiness-for-change was determined to be prosocial attitudes and related behavioral goals. In the next phase of this extended project, researchers will lengthen follow-up assessments to 24 months in addressing issues related to the prediction of a youth's intervention response based on cognitive and environmental variables. 3 tables and 2 figures
