ObjectiveThe goal of the current study was to examine the extent to which child sexual abuse (CSA) and particular characteristics of CSA are associated with pedophilic interest and sexual recidivism. MethodsSubjects were 462 adult male sexual offenders who had been incarcerated in Canadian federal prisons. ResultsCompared to sexual offenders who had not been sexually abused, those who had been sexually abused before age 16 sexually offended against significantly younger victims and had significantly more indicators of pedophilic interest. This was the case whether we examined self-reported or officially documented CSA. Offenders who had been sexually abused exclusively by a male had significantly more indicators of pedophilic interest than those who had been sexually abused exclusively by a female. These findings are consistent with past research and theory suggesting that CSA may play a role in pedophilia and sexual offending against children. CSA exclusively by a female abuser predicted higher rates of sexual recidivism than abuse by a male or both a male and female abuser. Among offenders with victims 15 years old or younger, a closer relationship between offender and abuser predicted higher rates of sexual recidivism. The relationship between CSA and sexual recidivism was significantly moderated by actuarial risk. More specifically, CSA predicted higher rates of sexual recidivism among higher risk offenders, but CSA did not predict sexual recidivism among lower risk offenders. This novel finding raises the possibility that CSA may play a role in sexual recidivism for some offenders. ConclusionIf future research replicates this CSA by risk interaction and identifies the constructs and processes involved, CSA may be worth considering in risk assessment and treatment.
