HCR-20 REVIEW AND ANNOTATED BIBLIOGRAPHY

Major mental illness 5. Supply and Services Canada: The HCR has a base of predictive validity studies, with a link to recidivism and good interrater reliability indexes; the SVR, given its newness, does not yet have such studies. Sex offender risk assessment and the law. Escalation in frequency or severity of sex offenses Should one give the historical items more weight? Those items associated with changes in recidivism were then subjected to a stepwise multiple regression to eliminate item redundancy Epperson, et al.

Past non-sexual violent offenses Mental disorder and violent behavior. Of course, if a plethysmograph were essential to assessing sex offender risk, if its elimination from an assessment battery led to poor predictions, and if there were no alternative methods of obtaining information about deviant sexual interest, then the time and money to include it in a standard battery might be defensible. What underlying factors describe the HCR’s structure, and how many items assess each factor? Additional studies are needed to address these questions. All scales start with some rational process of criterion selection based upon a review of the empirical literature.

The manual also provides studies of the HCR up toa relatively scant literature consisting of reliability and validity studies in correctional, forensic psychiatric, and civil psychiatric settings. Appraising and managing risk.

The literature indicates that two broad factors predict sex offenses: Each instrument is an admirable integration of research and clinical practice.

By actuarial, here I mean not only that the items, or criteria, were selected based on their empirical support in the literature, but also that the scale itself has predictive validity studies, having been empirically linked to recidivism.
