The relationship between deviant sexual arousal, as measured by auditory phallometric stimuli, and psychopathy, as measured by the Psychopathy Checklist-Revised, was examined in 156 incest offenders, 260 extrafamilial child molesters, and 123 rapists. Subjects in each group had never been convicted of another type of sexual offense. Replicating previous research, rapists were more psychopathic than incest offenders and child molesters. Deviant sexual arousal to auditory stimuli was evident only on the Pedophile Index for child molesters. When the relationship between psychopathy and deviant sexual arousal was evaluated in the three groups combined, several significant correlations emerged. However, a finer analysis of these correlations revealed that child molesters evidenced a significant correlation between psychopathy and the Rape Index and psychopathy and the Pedophile Index. There were no such significant findings in the incest offender or rapist groups. Implications of the results are discussed.
