Thirty male adolescent sex offenders and 20 age-matched male adolescents completed an extensive battery of attention and executive function tests. Controls were obtained from adolescents from a socially and economically deprived background, typical of the offending group. The attention battery was based on Mirksy, Anthony, Duncan, Ahearn, and Kellam (1991) and the executive function battery on Kelly (2000a). Successful matching for IQ was not achieved and therefore ANCOVA comparisons were made between the groups, with IQ as the covariate. In attention a highly significant difference was found on the focus-execute factor and a significant difference on the shift factor. In executive function there was a highly significant difference only on the response speed factor. In all cases better abilities were demonstrated by the control group. The importance of thorough neuropsychological investigation in the clinical assessment of this forensic group is supported. The clinical implications of neuropsychological deficits in terms of risk assessment and clinical management are discussed.

This paper differentiates four subgroups on the basis of victim characteristics within a sample of 100 British sexually abusive male adolescents aged between 11 and 18 years. The groups were compared in terms of their background characteristics and sexually abusive behavior. Results indicated that when subgroups were delineated on the basis of victim characteristics, they could be reliably differentiated on several abuser and abuse characteristics. Findings were generally consistent with those described in the North American literature. The implications of these findings are discussed in relation to etiology and to the development of a taxonomic classification system for British sexually abusive adolescents.

A personality-based taxonomy of an out-patient sample of 112 sexually abusive adolescents is described. Five subgroups were derived from cluster analytic procedures applied to Personality Patterns scales scores from the Millon Adolescent Clinical Inventory (MACI), and were named: Normal, Antisocial, Submissive, Dysthymic/Inhibited, and Dysthymic/Negativistic. The groups were also found to be differentiated on the psychopathology scales of the MACI. The results of the study provide evidence of the heterogeneity of adolescent sexual abusers in both personality characteristics and psychopathology. Comparison of groups differentiated on the basis of victim characteristics did not indicate a relationship between personality and sexual offence.
