| Abstract: | The Historical Clinical Risk Management-20 Version 3 is the latest iteration in the HCR-20 series, adopting novel changes such as the addition of Relevance ratings and non-requirement to include the Psychopathy Checklist–Revised. This study aimed to examine these changes and compare the predictive validity of the HCR-20V3 to the HCR-20V2. The sample comprised of 100 forensic psychiatric patients, retrospectively followed up for a maximum period of approximately 13 years post-discharge from the Thomas Embling Hospital. Recidivism data were sourced from official police records. Results indicated good to excellent inter-rater reliability. The HCR-20V3 significantly predicted violent recidivism (area under the curve = .70 to .77), levels of accuracy that were not significantly different from the HCR-20V2. HCR-20V3 Relevance ratings failed to add incremental validity above Presence ratings; however, the PCL–R improved upon the HCR-20V3’s validity. The study represented one of the first evaluations of the HCR-20V3 in Australia. |
