This paper reports on a follow-up of a sample of 303 adolescent male sex offenders from New South Wales, Australia. Adult rearrest and reconviction data were obtained for 292 of these individuals. The mean observation period between their adjudication as adolescents and their follow-up as adults was 7.3 years. Seventy-five (25%) received further convictions for sexual offenses prior to their 18th birthday. As adults, 25 (9%) came to the attention of police for further alleged sexual offenses, including 14 (5%) who received convictions for these offenses. Of these, 11 (79%) also received new convictions for nonsexual offenses. Overall, 61.3% of subjects received convictions for nonsexual offenses as adults. Results suggest considerable diversity and persistence in delinquent and criminal behavior, and challenge assumptions about high transition rates from adolescent to adult sexual offending.

Increasing attention is being paid to best practice in mental health sciences. One crucial aspect of this is the extent to which the mental health workforce has the knowledge and skills to implement state-of-the-art interventions. Recently, evidence has indicated that sexual offending often begins in adolescence, can be a persistent disorder when left untreated, and is associated with a range of other mental health problems in the perpetrator and subsequently in victims. A small number of evaluations of treatment programs are appearing but little work has appeared addressing the issue of how the workforce is equipped, or can be trained, to work with this challenging population. In this paper we present data on the effects of training on knowledge, skills, confidence, and willingness, to work with this client group. Trainees were 107 mental health workers who attended training workshops provided throughout Queensland, Australia by the Griffith Adolescent Forensic Assessment and Treatment Centre. Results showed that the measures developed for assessing training effects were change sensitive and valid. Training was associated with increases in self-rated skills, confidence, knowledge, and willingness to work with this population, and these changes were maintained for the follow-up sample.

Characteristics of adolescents who sexually offend, their patterns of their offending behaviour and the defining features of their victims are firmly established in the overseas literature. The research literature in Australia, however, is less developed. This study describes the characteristics of a sample of clients of the Sex Offender Program of the New South Wales Department of Juvenile Justice and examines patterns of offence behaviours and related descriptions of victims. Adolescents who sexually offend in NSW have backgrounds of low educational attainment and abuse and a range of other social risk factors, and they are most likely to victimise female children. A typology of adolescent sex offenders based on their offending behaviour is offered.
