The present study explored the predictive validity of two measures designed to assess risk for sexual recidivism in adolescent sexual offenders (ASO), the Juvenile Sex Offender Assessment Protocol—II and the Estimate of Risk of Adolescent Sexual Offense Recidivism, in the context of an antisociality-based typology of adolescent sexual offenders. The authors distinguished between adolescent sexual offenders with a history of general offending (delinquent ASO) and adolescent sexual offenders without a history of general offending (sex offense—only ASO). They found differential predictive accuracy of risk measures according to offender type: Both instruments predicted sexual recidivism in the sex offense—only ASO group (large effect sizes), whereas in the delinquent ASO group, the measures did not predict sexual recidivism beyond chance levels. Risk assessment in the context of an antisociality-based sex offender typology is discussed.
