A cross-validation of the Violence Risk Appraisal Guide-Revised (VRAG-R) within a correctional sample.

Résumé

The Violence Risk Appraisal Guide-Revised (VRAG-R) was developed to replace the original VRAG based on an updated and larger sample with an extended follow-up period. Using a sample of 120 adult male correctional offenders, the current study examined the interrater reliability and predictive and comparative validity of the VRAG-R to the VRAG, the Psychopathy Checklist-Revised, the Statistical Information on Recidivism-Revised, and the Two-Tiered Violence Risk Estimate over a follow-up period of up to 22 years postrelease. The VRAG-R achieved moderate levels of predictive validity for both general and violent recidivism that was sustained over time as evidenced by time-dependent area under the curve (AUC) analysis. Further, moderate predictive validity was evident when the Antisociality item was both removed and then subsequently replaced with a substitute measure of antisociality. Results of the individual item analyses for the VRAG and VRAG-R revealed that only a small number of items are significant predictors of violent recidivism. The results of this study have implications for the application of the VRAG-R to the assessment of violent recidivism among correctional offenders. (PsycINFO Database Record
