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.

Multisystemic Treatment of Adolescent Sexual Offenders

This study compared the efficacy of multisystemic therapy (MST) and individual therapy (IT) in the outpatient treatment of adolescent sexual offenders. Sixteen adolescent sexual offenders were randomly assigned to either MST or IT conditions. Youths in the MST and IT conditions received an average of 37 hours and 4S hours of treatment, respectively. Recidivism data were collected on all subjects at an approximately 3-year follow-up. Betweengroups comparisons showed that significantly fewer subjects in the MST condition had been rearrested for sexual crimes and that the frequency of sexual rearrests was significantly lower in the MST condition than in the IT condition. The relative efficacy of MST was attributed to its emphasis on changing behavior and interpersonal relations within the offenders natural environment.

Mechanisms of change in multisystemic therapy: Reducing delinquent behavior through therapist adherence and improved family and peer functioning.

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.

Multisystemic Treatment of Substance-Abusing and -Dependent Delinquents: Outcomes, Treatment Fidelity, and Transportability

The effectiveness and transportability of multisystemic therapy (MST) were examined in a study that included 118 juvenile offenders meeting DSM-III-R criteria for substance abuse or dependence and their families. Participants were randomly assigned to receive MST versus usual community services. Outcome measures assessed drug use, criminal activity, and days in out-of-home placement at posttreatment (T2) and at a 6-month posttreatment follow-up (T3); also treatment adherence was examined from multiple perspectives (i.e., caregiver, youth, and therapist). MST reduced alcohol, marijuana, and other drug use at T2 and total days in out-of-home placement by 50% at T3. Reductions in criminal activity, however, were not as large as have been obtained previously for MST. Examination of treatment adherence measures suggests that the modest results of MST were due, at least in part, to difficulty in transporting this complex treatment model from the direct control of its developers. Increased emphasis on quality assurance mechanisms to enhance treatment fidelity may help overcome barriers to transportability.

Four-Year Follow-up of Multisystemic Therapy With Substance-Abusing and Substance-Dependent Juvenile Offenders

OBJECTIVE Although several treatments for adolescent substance abuse have been identified as promising by reviewers and federal agencies, treatment effects extending beyond 12 months have not been demonstrated in randomized clinical trials. The primary purpose of this report was to examine the 4-year outcomes of an evidence-based treatment of substance-abusing juvenile offenders. METHOD Eighty of 118 substance-abusing juvenile offenders participated in a follow-up 4 years after taking part in a randomized clinical trial comparing multisystemic therapy (MST) with usual community services. A multimethod (self-report, biological, and archival measures) assessment battery was used to measure the criminal behavior, illicit drug use, and psychiatric symptoms of the participating young adults. RESULTS Analyses demonstrated significant long-term treatment effects for aggressive criminal activity (0.15 versus 0.57 convictions per year) but not for property crimes. Findings for illicit drug use were mixed, with biological measures indicating significantly higher rates of marijuana abstinence for MST participants (55% versus 28% of young adults). Long-term treatment effects were not observed for psychiatric symptoms. CONCLUSIONS Findings provide some support for the long-term effectiveness of an evidenced-based family-oriented treatment of substance-abusing juvenile offenders. The clinical, research, and policy implications of these findings are noted.

Family preservation using multisystemic treatment: Long-term follow-up to a clinical trial with serious juvenile offenders

In a randomized clinical trial, multisystemic family preservation was shown to significantly reduce rates of criminal activity and incarceration in a sample of 84 serious juvenile offenders and their multi-need families. In the current study, archival records were searched for re-arrest an average of 2.4 years post-referral. Survival analysis showed that youths who received multisystemic family preservation were less likely to be re-arrested than were youths who had received usual services. Such results represent the first controlled demonstration that family preservation, when delivered via a clearly specified treatment model, has lasting effects with serious juvenile offenders. Implications for family preservation and juvenile justice research are discussed.

Juvenile Drug Court: Enhancing Outcomes by Integrating Evidence-Based Treatments.

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.

Multisystemic Therapy Effects on Attempted Suicide by Youths Presenting Psychiatric Emergencies.

OBJECTIVE To evaluate the efficacy of multisystemic therapy (MST) in reducing attempted suicide among predominantly African American youths referred for emergency psychiatric hospitalization. METHOD Youths presenting psychiatric emergencies were randomly assigned to MST or hospitalization. Indices of attempted suicide, suicidal ideation, depressive affect, and parental control were assessed before treatment, at 4 months after recruitment, and at the 1-year posttreatment follow-up. RESULTS Based on youth report, MST was significantly more effective than emergency hospitalization at decreasing rates of attempted suicide at 1-year follow-up; also, the rate of symptom reduction over time was greater for youths receiving MST. Also, treatment differences in patterns of change in attempted suicide (caregiver report) varied as a function of ethnicity, gender, and age. Moreover, treatment effects were found for caregiver-rated parental control but not for youth depressive affect, hopelessness, or suicidal ideation. CONCLUSIONS Results generally support MSTs effectiveness at reducing attempted suicide in psychiatrically disturbed youngsters, whereas the effects of hospitalization varied based on informant and youth demographic characteristics.

Transporting Efficacious Treatments to Field Settings: The Link Between Supervisory Practices and Therapist Fidelity in MST Programs

Validated a measure of clinical supervision practices, further validated a measure of therapist adherence, and examined the association between supervisory practices and therapist adherence to an evidence-based treatment model (i.e., multisystemic therapy [MST]) in real-world clinical settings. Evidence of linkages between supervisor adherence to the MST supervisory protocol, as assessed through therapist reports, and therapist adherence to MST principles, as assessed through caregiver reports, was obtained from 285 families of youths presenting serious clinical problems, and 74 therapists and 12 supervisors of 16 teams in 9 organizations providing MST across 3 states. The findings provide a valuable step in examining the determinants of therapist fidelity to complex treatments in real-world clinical settings.

Multisystemic Therapy: An Overview of Clinical Procedures, Outcomes, and Policy Implications

Multisystemic therapy (MST) is a family- and community-based treatment that has successfully served as a clinical and cost-effective alternative to out-of-home placements (e.g. incarceration, psychiatric hospitalisation) for youths presenting serious clinical problems. MST clinical procedures and findings from MST outcome studies are reviewed. Several key features differentiate MST from prevailing mental health and juvenile justice practices and probably account for its relative success. These features include interventions that comprehensively address the known determinants of clinical problems, the provision of services in home and community settings to promote service access and ecological validity, and a philosophy that emphasises provider accountability for family engagement and outcomes.
