Compared to youth who participated in the standard services of the Juvenile Diversion program, the youth who received the additional 16 weeks of intensive case-management services had higher rates of program completion; however, the youths who received the intensive case-management services were no more likely to complete the diversion program on time than the youths who received standard services. The results of psychopathy measurement were not significantly related to program completion regardless of whether youth received standard diversion services or intensive case management. The intervention group received additional arbitration intervention services from trained paraprofessional Arbitration Intervention Workers (AIWs) who were hired exclusively for this clinical trial. The AIW's objectives were to assist the youth's family in determining what additional services might benefit the family and to help the youth avoid further delinquent behavior. AIWs also monitored and encouraged the youth to complete the sanctioning requirements of the standard Juvenile Diversion program. The comparison involved 165 youth who chose to participate in the additional intensive case-management services and the 194 youth who chose to receive the standard diversion services but not the intensive case management. The youth entered the diversion program between June 2002 and July 2003. 6 tables and 56 references
