In this study, we examined the association of hostility, as measured by the Buss-Durkee Hostility Inventory (BDHI), with offence characteristics and recidivism in 656 adult male sexual offenders. Hostility was significantly associated with having prior violent charges, the use of violence in the index sexual offence, sexual recidivism, and violent recidivism. After controlling for risk level, as measured by a modified version of the Rapid Risk Assessment for Sexual Offence Recidivism (RRASOR-mod), the significant association between hostility and sexual and violent recidivism remained. When examined by type of offender, hostility was significantly associated with recidivism in intrafamilial and extrafamilial child molesters, but not in rapists or mixed offenders. Given the predictive value of hostility independent of the RRASOR-mod, the present findings confirm and encourage treatment efforts directed toward the management of hostility and anger in sexual offenders.
