Psychopathology The Hare Psychopathy Checklist-Revised (PCL-R) was utilized to assess subject's psychopathology (Hare, 1998). The Minnesota Sex Offender Screening Tool-Revised (MnSOST-R) identified the most violent offenders and those offenders likely to re-offend (Epperson et al., 1999). The Static-99, another sexual offender risk assessment, measured long-term risk potential for child molesters (Hanson & Thornton, 1999). The Yale-Brown Obsessive Compulsive Scale (Y-BOCS) was utilized because of an inferred relationship between obsessive compulsive disorder and sexual paraphilias (Goodman et al., 1989).
