Validation of and revision to the VRAG and SORAG: the Violence Risk Appraisal Guide-Revised (VRAG-R)
Abstract
The violence risk appraisal guide (VRAG) was developed in the early 1990s, and approximately 60 replications around the world have shown its utility for the appraisal of violence risk among correctional and psychiatric populations. At the same time, authorities (e.g., Dawes, Faust, & Meehl, 1989) have argued that tools should be periodically evaluated to see if they need to be revised. In the present study, we evaluated the accuracy of the VRAG in a sample of 1,261 offenders, fewer than half of whom were participants in the development sample, then developed and validated a revised and easier-to-score instrument (the VRAG-R). We examined the accuracy of both instruments over fixed durations of opportunity ranging from 6 months to 49 years and examined outcome measures pertaining to the overall number, severity, and imminence of violent recidivism. Both instruments were found to predict dichotomous violent recidivism overall and at various fixed follow-ups with high levels of predictive accuracy (receiver operating characteristic areas of approximately .75) and to significantly predict other violent outcomes.
