Multisystemic therapy with violent and chronic juvenile offenders and their families: the role of treatment fidelity in successful dissemination.

The effects of multisystemic therapy (MST) in treating violent and chronic juvenile offenders and their families in the absence of ongoing treatment fidelity checks were examined. Across 2 public sector mental health sites, 155 youths and their families were randomly assigned to MST versus usual juvenile justice services. Although MST improved adolescent symptomology at posttreatment and decreased incarceration by 47% at a 1.7-year follow-up, findings for decreased criminal activity were not as favorable as observed on other recent trials of MST. Analyses of parent, adolescent, and therapist reports of MST treatment adherence, however, indicated that outcomes were substantially better in cases where treatment adherence ratings were high. These results highlight the importance of maintaining treatment fidelity when disseminating complex family-based services to community settings.

Female juvenile delinquency: misunderstood by the juvenile justice system, neglected by social science.

The study of juvenile delinquency has focused primarily on conduct disorder and aggression in males, while relatively little attention has been paid to females who commit delinquent acts. This article offers a critical review of the existing theories of and research on female delinquency and the juvenile justice system's response to female delinquency. The inadequacies and persistence of historical theories and the conceptual and methodological strengths and weaknesses of contemporary perspectives in female delinquency are reviewed. Understanding and treatment of female and male delinquency could be enhanced through the adoption of a gender-integrated theory of delinquency that is informed by the comprehensive study of developmental, psychological, and social-ecological determinants.
