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.
