Abstract

Development of a comprehensive typology for the classification of sexual offenders has important implications for both risk prediction and treatment. To date, the most comprehensive typological system has been developed by Knight and Prentky (1990). These authors have developed typologies for both child molesters and rapists. The system for rapists has been replicated on at least two samples (Barbaree, Seto, Serin, Amos, & Preston, 1994; Brown & Forth, 1997); however, the child molester typology has yet to be fully replicated outside the MTC. In the present study, 109 child molesters who were assessed or treated at the Regional Treatment Centre (Ontario) were classified according to the MTC child molester typology. Interrater reliabilities were obtained for 20 participants and ranged from .90 to .40, which are comparable to those obtained in the MTC sample. Groups were compared on a number of meaningful variables, such as number of victims and sexual deviance.
