Abstract: The research addressing sex offender assessment and treatment is an ever-evolving science. However, very little research has addressed psychological typologies associated with various types of sex offenders and treatment engagement. The current study examined assessment data of four sex offender groups, defined by victim type, to determine if a typological difference exists between groups of (N = 583) rapists (n = 129), statutory offenders (n = 140), intrafamilial/ incest perpetrators (n = 152), and extrafamilial (n = 162). Secondly, the study determined if a specific battery of psychological measures can predict treatment completion (n = 377). We also hypothesized there will be a negative relationship between psychopathy, as measured by the Hare Psychopathy Checklist-Screening Version, antisociality, aggression, and treatment rejection, as measured by the Personality Assessment Inventory, and treatment completion. As hypothesized, there were several significant differences seen between the sex offender groups. Rapists were significantly different from the other three sex offender groups and Extrafamilial Child Molester and Statutory Offender groups were similar to one another. The primary discriminating factors appeared to be the level of antisocial beliefs, attitudes and behaviors. Static-99 scores were highest for the Rapist group and post hoc analyses indicated that Extrafamilial Child Molesters with male only or both male and female victims had similar Static-99 scores to rapists. As hypothesized, psychopathy and PAI Antisocial and Aggression scales scores distinguished between treatment completers and non-completers, however, these variables were not predictive of treatment completion.
