Personality disorders in men with sexual and violent criminal offense histories.

Little is known about personality disorders (PDs) in offenders with histories of both sexual and (nonsexual) violent offenses. This study aimed to identify possible differences of PD profiles across three different offender groups with both sexual and violent (S+V), only sexual (S), and only violent (V) offenses. Nonviolent (N) offenders were used as a comparison group. Typing of individuals according to their offensive histories was performed on the basis of 259 psychiatric court reports that included the Structured Clinical Interview (SCID)-II for PD diagnostics. Men from the S+V group committed significantly more acts of rape and sexual coercion than the mere sexual offenders. Furthermore, S+V offenders showed the highest rates of PDs overall (68.3%), with every second offender being diagnosed with an antisocial PD and every third offender with a borderline PD. In summary, the results suggest that S+V offenders form a group of individuals with remarkable differences regarding PD profiles, the relatively highest frequencies of conduct disorders, familial addictive problems, and PDs overall.
