Static-99r Scores in a Population of Civilly Committed Sexual Offenders with a Diagnosis of Paraphilic Disorder and Antisocial Personality Disorder

The purpose of this study was to distinguish between the risk of sexual recidivism for civilly committed sexual offenders with a diagnosed paraphilic disorder with comorbid antisocial personality disorder (ASPD) compared to those with a paraphilic disorder alone. The present study used annual forensic evaluations of sexual offenders who are civilly committed to a state hospital under a Sexually Violent Predator Act to examine the relationship between a paraphilic disorder with a comorbid diagnosis of ASPD and scores on the Static-99R, one of the most commonly used actuarial risk assessment instruments for predicting sexual recidivism. Subjects with a comorbid diagnosis of a paraphilic disorder and ASPD were hypothesized to have a higher Static-99R score compared to those with a paraphilic disorder alone. This study found that the Static-99R risk score was significantly higher for subjects with a paraphilic disorder with a comorbid diagnosis of ASPD and that there was a significant relationship between the risk score of a subject and these diagnoses. Subjects diagnosed with a paraphilic disorder with a comorbid diagnosis of ASPD were three times more likely than those with a paraphilic disorder alone to be in a higher nominal risk category than subjects without the comorbid diagnosis. The findings of this study reinforce the idea that offenders with a comorbid diagnosis of paraphilic disorder and ASPD require a higher level of risk management and treatment.
