Multisystemic therapy (MST) delivered through a community mental health center was compared with usual services delivered by a Department of Youth Services in the treatment of 84 serious juvenile offenders and their multiproblem families. Offenders were assigned randomly to treatment conditions. Pretreatment and posttreatment assessment batteries evaluating family relations, peer relations, symptomatology, social competence, and self-reported delinquency were completed by the youth and a parent, and archival records were searched at 59 weeks postreferral to obtain data on rearrest and incarceration. In comparison with youths who received usual services, youths who received MST had fewer arrests and self-reported offenses and spent an average of 10 fewer weeks incarcerated. In addition, families in the MST condition reported increased family cohesion and decreased youth aggression in peer relations. The relative effectiveness of MST was neither moderated by demographic characteristics nor mediated by psychosocial variables.

This article examined the long-term effects of multisystemic therapy (MST) vs. individual therapy (IT) on the prevention of criminal behavior and violent offending among 176 juvenile offenders at high risk for committing additional serious crimes. Results from multiagent, multimethod assessment batteries conducted before and after treatment showed that MST was more effective than IT in improving key family correlates of antisocial behavior and in ameliorating adjustment problems in individual family members. Moreover, results from a 4-year follow-up of rearrest data showed that MST was more effective than IT in preventing future criminal behavior, including violent offending. The implications of such findings for the design of violence prevention programs are discussed.

The mechanisms through which multisystemic therapy (MST) decreased delinquent behavior were assessed in 2 samples of juvenile offenders. Sample 1 included serious offenders who were predominantly rural, male, and African American. Sample 2 included substance-abusing offenders who were predominantly urban, male, and Caucasian. Therapist adherence to the MST protocol (based on multiple respondents) was associated with improved family relations (family cohesion, family functioning, and parent monitoring) and decreased delinquent peer affiliation, which, in turn, were associated with decreased delinquent behavior. Furthermore, changes in family relations and delinquent peer affiliation mediated the relationship between caregiver-rated adherence and reductions in delinquent behavior. The findings highlight the importance of identifying central change mechanisms in determining how complex treatments such as MST contribute to ultimate outcomes.

Evaluated the effectiveness of juvenile drug court for 161 juvenile offenders meeting diagnostic criteria for substance abuse or dependence and determined whether the integration of evidence-based practices enhanced the outcomes of juvenile drug court. Over a 1-year period, a four-condition randomized design evaluated outcomes for family court with usual community services, drug court with usual community services, drug court with multisystemic therapy, and drug court with multisystemic therapy enhanced with contingency management for adolescent substance use, criminal behavior, symptomatology, and days in out-of-home placement. In general, findings supported the view that drug court was more effective than family court services in decreasing rates of adolescent substance use and criminal behavior. Possibly due to the greatly increased surveillance of youths in drug court, however, these relative reductions in antisocial behavior did not translate to corresponding decreases in rearrest or incarceration. In addition, findings supported the view that the use of evidence-based treatments within the drug court context improved youth substance-related outcomes. Clinical and policy implications of these findings are discussed.
