This research assesses the recidivism rates of a sample of 300 registered male sex offenders who were juveniles at the time of their initial arrest for a sex offense. This sample is followed for 3 to 6 years after they reached adulthood; recidivism rates are assessed during their adulthood only. The typical juvenile is a 15-year-old Caucasian male who was arrested for sexual assault or indecency with a child. The majority of the victims are females with an average age of 8. Although only 13 are rearrested during the follow-up period for a sex offense, more than half of the sample is arrested at least once for a nonsexual offense. The results of a Cox regression indicate that victim age, offender age, and victim sex are significant predictors of recidivism during adulthood. (Contains 5 notes and 4 tables.)
