The authors investigated whether psychopathy would contribute to the understanding of the heterogeneity of sexual violence. Using the Psychopathy Checklist-Revised, presence of psychopathy, callous personality (Factor 1), and chronic antisocial conduct (Factor 2) were examined in a diverse sample (N=329) of incarcerated sex offenders and nonsexual offenders categorized according to the nature of their crimes. Mixed rapist/molesters and rapists were more psychopathic than child molesters, although all sex offender groups showed elevated Factor 1 scores. A high proportion (64%) of offenders who had victimized both children and adults were psychopathic, indicative of a criminal whose thrill seeking is directed at diverse sexual victims (appropriately called a sexual psychopath). Furthermore, there were different factor scores and an interaction between factor scores and offense type. These profiles have implications for treatment and a comprehensive theory of sexual violence.
