Abstract

The current study presents an empirical evaluation of the performance of the third version of the HCR-20. This prospective research project was conducted using a sample of 106 offenders and psychiatric patients who were transitioning out of institutions and into the community. Results provided strong support for the bivariate associations between the ratings of the presence and relevance of risk factors, as well as summary risk ratings, and violence at 4 to 6 weeks and 6 to 8 months. Although relevance ratings did not add incrementally to presence ratings, summary risk ratings added incrementally to both. Findings were not moderated by either sub-sample or gender. Version 3 of the HCR-20 was highly correlated with Version 2. Associations with violence were comparable between instruments. Findings were supportive of these basic elements of Version 3. © 2014 International Association of Forensic Mental Health Services.
