Psychopathy and sexual deviance in treated rapists: Association with sexual and nonsexual recidivism

This study examined the role of the Psychopathy Checklist-Revised (PCL-R; R. D. Hare, 1991) and sexual deviance scores in predicting recidivism in a sample of 94 convicted rapists involuntarily admitted to a Dutch forensic psychiatric hospital between 1975 and 1996 The predictive utility of grouping offenders based on the combination of psychopathy and sexual deviance was also investigated. Measures were coded from prerelease institutional records. Recidivism (reconviction) data were retrieved from the Judicial Documentation Register of the Ministry of Justice and were related to PCL-R and sexual deviance scores. The follow-up period after release ranged up to 23.5 years (M = 11.8 years). Base rates for sexual, violent nonsexual, violent (including sexual), and general recidivism were 34%, 47%, 55%, and 73%, respectively. For all types of offending, offenders scoring high on the PCL-R (greater than or equal to26) were significantly more often reconvicted than other offenders. The sexual deviance score was found to be a significant predictor of sexual reconviction. Survival analyses provided considerable evidence that psychopathic sex offenders with sexual deviant preferences are at substantially greater risk of committing new sexual offenses than psychopathic offenders without deviant preferences or nonpsychopathic offenders with or without sexual deviance. The findings are discussed in terms of their practical and clinical implications.
