Recidivism rates of juvenile delinquents remain high despite numerous intervention efforts. Identifying factors that can predict (long-term) recidivism is therefore an important research issue. Knowledge on why juveniles re-offend is a key to effective interventions as it helps to identify factors most likely to be successful targets in intervention programs. A 10-year follow-up study prospectively examined whether psychopathic traits and supportive parental practices predicted the timing and frequency of recidivism in juvenile delinquents. Participants were 256 adolescents who were referred to treatment for serious antisocial behavior (72.4% male). Participants were between 12 and 18 years old at baseline (M= 15.9 years). Parents reported on juveniles’ psychopathic traits and supportive parental practices at baseline. At 10-year follow-up, the official recidivism data were collected. A substantial number of juveniles (86.3%) had recidivated at 10-year follow-up. Juvenile psychopathic traits and supportive parental practices did not incrementally predict the timing or frequency of recidivism over time over and beyond the static control variables gender and prior offenses. The present study confirms previous work suggesting that static risk factors gender and prior offenses are strongest predictors of recidivism.

The effects of home visiting programs to reduce child maltreatment are generally limited and warrant improvement. The present study, therefore, examined whether the effectiveness of a home visitation program in the Netherlands can be improved by adding specific intervention components targeting important risk factors for child maltreatment, namely parental stress, parental anger, and PTSD symptoms. Using a single-case experimental design, nine mothers were assessed weekly during 36 weeks of the Dutch home visiting program VoorZorg, comparing baseline, treatment (i.e., phase with added intervention components), and follow-up. Outcome effects were examined using statistical analyses on a group level and combining statistical and visual analyses on a case level for primary outcomes: perceived stress, parental anger, and PTSD symptoms, and secondary outcomes: risk of child maltreatment and parental sense of competence. As a group, mothers showed a reduction of anger in response to the additional components. No group effects were found for other outcomes. At an individual level, three mothers showed only positive effects, four mothers showed no intervention effects, and two mothers showed mixed effects (i.e., positive on some outcomes and negative on other). Consequently, the component targeting parental anger seems promising, because it can easily be implemented, but it is important to prevent any possible detrimental effects. Effects of the component targeting stress depended on the use of relaxation exercises, and therefore this component should be expanded in such a way that it is more feasible for mothers to implement it.
