The present study used general growth mixture modeling to identify pathways of antisocial behavior development within an epidemiological sample of urban, primarily African American boys. Teacher-rated aggression, measured longitudinally from 1st to 7th grade, was used to define growth trajectories. Three high-risk trajectories (chronic high, moderate, and increasing aggression) and one low-risk trajectory (stable low aggression) were found. Boys with chronic high and increasing trajectories were at increased risk for conduct disorder, juvenile and adult arrest, and antisocial personality disorder. Concentration problems were highest among boys with a chronic high trajectory and also differentiated boys with increasing aggression from boys with stable low aggression. Peer rejection was highest among boys with chronic high aggression. Interventions with boys with distinct patterns of aggression are discussed.Antisocial behavior is among the most common and serious mental health problems presently faced in the United States (Kessler et al., 1994). Conduct disorder is one of the most prevalent disorders of childhood (3%-10%; Lewinsohn, Hops, Roberts, Seeley, & Andrews, 1993) and is associated with an array of other problems, including school failure, substance abuse, and adult psychiatric disorder (

The primary purpose of this study was to conduct a randomized effectiveness trial of Multisystemic Therapy for Child Abuse and Neglect (MST-CAN) for physically abused youth (mean age = 13.88 years, 55.8% female, 68.6% Black) and their families. Eighty-six families being followed by Child Protective Services due to physical abuse were randomly assigned to MST-CAN or Enhanced Outpatient Treatment (EOT), with both interventions delivered by therapists employed at a community mental health center. Across five assessments extending 16 months post baseline, intent-to-treat analyses showed that MST-CAN was significantly more effective than EOT in reducing youth mental health symptoms, parent emotional distress, parenting behaviors associated with maltreatment, youth out-of-home placements, and changes in youth placement. Also, MST-CAN was significantly more effective at improving natural social support for parents. Effect sizes were in the medium to large range for most outcomes examined. Although fewer children in the MST-CAN condition experienced an incident of reabuse than did counterparts in the EOT condition, base rates were low and this difference was not statistically significant. The findings of this study demonstrate the potential for broad-based treatments of child physical abuse to be effectively transported and implemented in community treatment settings.

A randomized clinical trial evaluated the efficacy of multisystemic therapy (MST) versus usual community services (UCS) for 48 juvenile sexual offenders at high risk of committing additional serious crimes. Results from multiagent assessment batteries conducted before and after treatment showed that MST was more effective than UCS in improving key family, peer, and academic correlates of juvenile sexual offending and in ameliorating adjustment problems in individual family members. Moreover, results from an 8.9-year follow-up of rearrest and incarceration data (obtained when participants were on average 22.9 years of age) showed that MST participants had lower recidivism rates than did UCS participants for sexual (8% vs. 46%, respectively) and nonsexual (29% vs. 58%, respectively) crimes. In addition, MST participants had 70% fewer arrests for all crimes and spent 80% fewer days confined in detention facilities than did their counterparts who received UCS. The clinical and policy implications of these findings are discussed.

Multiple group analysis and general growth mixture modeling was used to determine whether aggressive-disruptive behavior trajectories during elementary school, and their association with young adulthood antisocial outcomes, vary by gender. Participants were assessed longitudinally beginning at age 6 as part of an evaluation of 2 school-based preventive programs. Two analogous trajectories were found for girls and boys: chronic high aggression-disruption (CHAD) and stable low aggressiondisruption (LAD). A 3rd class of low moderate aggression-disruption (LMAD) for girls and increasing aggression-disruption (IAD) for boys also was found. Girls and boys in analogous CHAD classes did not differ in trajectory level and course, but girls in the CHAD and LAD classes had lower rates of antisocial outcomes than boys. Girls with the LMAD trajectory differed from boys with the IAD trajectory.

In this study, the authors examined the long-term criminal activity of 176 youths who had participated in either multisystemic therapy (MST) or individual therapy (IT) in a randomized clinical trial (C. M. Borduin et al., 1995). Arrest and incarceration data were obtained on average 13.7 (range = 10.2-15.9) years later when participants were on average 28.8 years old. Results show that MST participants had significantly lower recidivism rates at follow-up than did their counterparts who participated in IT (50% vs. 81%, respectively). Moreover, MST participants had 54% fewer arrests and 57% fewer days of confinement in adult detention facilities. This investigation represents the longest follow-up to date of a MST clinical trial and suggests that MST is relatively effective in reducing criminal activity among serious and violent juvenile offenders.
