Sex offenders who claim amnesia for their alleged offense.

Information relating to demography, history, and psychiatric functioning was collected for 20 consecutive individuals presenting to the Sexual Behaviours Clinic of the Royal Ottawa Hospital who claimed amnesia for their alleged sexual offenses. In addition, comparison groups of admitter and nonadmitter sex offenders were established to isolate relevant psychopathological constructs within the primary study group. Amnestic offenders displayed higher degrees of violence and fulfilled diagnostic criteria for potentially more harmful paraphilia.
