The sample for the study consisted of 256 convicted male juvenile offenders who were included in a needs assessment survey conducted in 1990 by the Washington State Department of Social and Health Services. The needs assessment yielded baseline descriptive information on each member of the sample. Additional descriptive data on the sexual offender behavior of the juveniles who were convicted of sex offenses were collected from Division of Juvenile Rehabilitation case files. Criminal history and recidivism information during a 3-year follow-up period was collected from multiple official sources. Findings show that the sex offenders were significantly more likely than the non-sex offenders to have been victims of sexual abuse. They were also more likely to have been assessed as having a major mental health dysfunction, to need health or dental hygiene education, to have no age appropriate peer relationships, and to have problems with sexual identity. The juvenile sex offenders were more likely to have been performing adequately in school prior to commitment and were less likely to have prior convictions of any kind. They were also less likely to be using or abusing drugs or alcohol. The sex offenders presented a lower risk of reoffending during the follow-up period than the non-sex offenders. The juvenile sex offenders were not specialists in offending, but rather were involved in other types of criminal behavior as well, generally to a greater extent than their involvement in sexual offending. 11 tables and 2 figures
