Examining the developmental trajectories of adolescent sexual offenders

The aim of the current study was to assess the validity of the sex-plus versus sex-only categorization method for distinguishing between different types of adolescent sex offenders (ASOs; Butler & Seto, 2002). It is hypothesized that this categorization method has utility when attempting to distinguish between generalist and specialist ASOs (Seto & Pullman, 2014). Additionally, further classification of ASOs was attempted using a well known juvenile delinquency classification scheme, early-onset versus late-onset offenders (Moffitt, 1993). The current study was an archival analysis of clinical files from a sample of 158 male ASOs seen for clinical assessment at a Metropolitan Family Court Clinic. Results indicate that sex-plus offenders are more antisocial, exhibit more psychiatric issues, and have greater deficits in general social skills compared to sex-only offenders. Conversely, sex-only offenders were found to have more atypical sexual interests, and were more likely to have greater deficits in romantic relationships compared to sex-plus offenders. Due to a power related limitation, little support was found for the use of the early-onset versus late-onset classification scheme with ASOs. Overall, these results provide further support to the validity of a sex-only versus sex-plus distinction. Given these results mirror those found in the generalist/specialist literature regarding the etiology of ASOs, sex-only and sex-plus offenders may indeed have different etiological pathways: sex-plus offenders are more driven by general antisociality factors, as the generalist perspective suggests, and sex-only offenders are more driven by special factors, as the specialist explanations suggest.     

Treating children with early-onset conduct problems and callous–unemotional traits: an empirical evaluation of KooLKIDS

Children with early-onset conduct problems (EOCP) and callous–unemotional (CU) traits are highly resistant to treatment and cost society significantly more than their healthy counterparts. Employing a multiple baseline design, 13 males (9.0–10.2 years of age) with a history of school suspensions were sequentially introduced to KooLKIDS, a school-based interactive multimedia intervention for young children with EOCP and CU. Teacher and child self-report data revealed significant reductions for the group in proactive and reactive aggression, and antisocial traits. Significant changes in the desired direction were also found on measures of emotion regulation. When the data were analyzed for each individual child, however, the magnitude of any effects for behaviour change varied greatly. KooLKIDS offers potential for treating children with EOCP and CU and hence preventing progression towards more serious antisocial behaviour.
