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 psychiatric 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.

Despite high prevalence, child neglect has long been passed over in research. Serious long-term consequences call for effective intervention programs. However, as a result of the lack of research, there is a lack of effective interventions. In order to develop such intervention programs and to maximize the effectiveness of existing programs, it is necessary to examine what factors are related to the reduction of neglect and, subsequently, what change mechanisms their effectiveness is based on. In this intervention study we investigated whether changes in parental mental health and parental stress after Multisystemic Therapy for Child Abuse and Neglect (MST-CAN), an effective evidence-based intervention program for child neglect, are related to changes in child neglect. Study participants were 144 parent-child dyads participating in the MST-CAN program. We analyzed changes from pre- to post-treatment in child neglect, parental mental health, and parental stress, and conducted a multiple regression analysis to examine whether changes in parental mental health and parental stress predict changes in child neglect. Our results showed that child neglect, as well as parental stress, significantly decreased and parental mental health significantly improved during the program. While improvements in parental mental health were not related to the reduction of child neglect, a decrease in parental stress significantly predicted the reduction of child neglect. These findings suggest that parental stress might be a promising target for evidence-based intervention programs to reduce the occurrence of child neglect. Implications and suggestions for further research are discussed.
