Long-awaited HCR-20 update to premiere in Scotland

The long-awaited international launch of the third version of the popular HCR-20 violence risk assessment instrument has been announced for next April in Edinburgh, Scotland.

The HCR-20 is an evidence-based tool using the structured professional judgment method, an alternative to the actuarial method that predicts violence at least as well while giving a more nuanced and individualized understanding. It has been evaluated in 32 different countries and translated into 18 languages.

A lot has changed in the world of risk prediction since the second edition premiered 15 years ago. Perhaps the major change in the third edition is the elimination of the need to incorporate a Psychopathy Checklist (PCL-R) score; research determined that this did not add to the instrument's predictive validity. Additionally, like the sister instrument for sex offender risk assessment, the RSVP, the HCR:V3 will focus more heavily on formulating plans to manage and reduce a person's risk, rather than merely predicting violence.

The revision process took four years, with beta testing in England, Holland, Sweden and Germany. Initial reports show very high correlations with the second edition of the HCR-20, excellent interrater reliability, and promising validity as a violence prediction tool.

The HCR:V3 will be launched at a one-day conference jointly organized by The Royal Society of Edinburgh and Violence Risk Assessment Training. Developers Christopher Webster, Stephen Hart and Kevin Douglas will be on hand to describe the research on the new instrument and its utility in violence risk assessment.

More information on the April 15, 2013 training conference is available HERE. A Webinar PowerPoint on the revision process is HERE.
