Show moreNot only are childhood onset offenders at high risk of becoming serious persistent offenders, they are also at high risk of becoming victimized themselves. Furthermore, studies in the general population suggest that a combined perpetrator-victim group can be distinguished from a perpetrator-only and a victim-only group on individual and family risk factors. The current study investigated the co-occurrence of offending and victimization among first-time arrestees and the 2-year predictive value of previously found clusters of dynamic risk factors of offending. Childhood first-time arrestees (N = 308; M-age = 10.3, SD = 1.45) were clustered into three groups based on dynamic risk factors of offending in the individual, peer, school, and family domains: a pervasive high, an externalizing intermediate, and a low problem group. Police records and self-report data on re-offending and victimization of these children were collected over a 2-year follow-up period. Compared with the low problem group, the prevalence of re-offending was higher in both the externalizing intermediate group and the pervasive high group. The pervasive high group was most likely to display co-occurring future antisocial behavior and victimization. These findings emphasize that attention should be paid to victimization in addition to future antisocial behavior, especially if additional internalizing and family problems are present. Furthermore, the differences in re-offending and victimization between subgroups of childhood onset offenders stress the need for specific interventions tailored to the risk profile of a child.

Show moreThe current study investigated the 18-month stability of self-reported psychopathic traits measured through the Youth Psychopathic traits Inventory–Child Version (YPI-CV) and their concurrent and prospective associations with conduct problems and aggression in a sample of 9–12year olds (n = 159, 52% boys) from the community. Self-reported psychopathy scores were moderately to highly stable and traits were positively related to conduct problems both concurrently and at follow-up, the latter even after controlling for initial levels of conduct problems. Higher self-reported psychopathic traits were also related to higher reactive, but particularly proactive aggression at follow-up. Finally, children with persistently high levels of psychopathic traits exhibited higher levels of conduct problems and proactive aggression at follow-up than those with unstable or stable low psychopathic traits.

Show moreObjective: To provide a best estimate of the prevalence of psychiatric disorders among detained male adolescents, with particular emphasis on impairment, multi-informant assessment, and race or ethnicity. Method: Computer-assisted searches were executed to identify relevant studies. Results: Fifteen studies using adolescents as informants met inclusion criteria (n = 3401), of which only 2 reported within a subsample on parent-derived diagnoses. The mean prevalence of any disorder was 69.9% (95% CI 69.5% to 70.3%); with conduct disorder occurring most frequently (46.4%, 95% CI 45.6% to 47.3%), followed by substance use disorder (45.1%, 95% CI 44.6% to 45.5%), oppositional defiant disorder (19.8%, 95% CI 19.2% to 20.3%), and attention-deficit hyperactivity disorder (13.5%, 95% CI 13.2% to 13.9%). Although lower, rates for internalizing disorders were still substantial, with any anxiety disorder found in 15.9% (95% CI 15.6% to 16.1%), major depression in 12.0% (95% CI 11.7% to 12.2%), and posttraumatic stress disorder in 9.6% (95% CI 9.2% to 10.0%). Three studies reported on psychotic disorders, finding low rates (1.35%, 95% CI 1.32% to 1.39%). Estimates of prevalence were only marginally different when impairment was not required, while consistency between adolescents and parents was poor. Findings on the relations between race or ethnicity were too scarce and inconsistent to interpret. Conclusion: Detained male adolescents bear substantial mental health needs, emphasizing the need to organize effective mental health services for this troubled group. However, our knowledge on mental disorders in detained youth should be enhanced, in particular regarding the reliability of adolescents, compared with parent report, and whether clinically relevant differences exist by race or ethnicity.
