Article Synopsis
- The Violence Risk Appraisal Guide-Revised (VRAG-R) was designed to improve the assessment of violent recidivism by using a larger sample and longer follow-up compared to the original VRAG.
- The study, involving 120 adult male offenders, found that the VRAG-R showed moderate predictive validity for recidivism and maintained effectiveness over up to 22 years post-release.
- Analysis indicated that only a few individual items in the VRAG and VRAG-R significantly predicted violent recidivism, suggesting that the tool is useful but may benefit from further refinement.
In two previous studies on general and violent recidivism (Walters & Heilbrun, 2010; Walters, Knight, Grann, & Dahle, 2008), the summed composite antisocial facet of the Psychopathy Checklist displayed incremental validity relative to the other 3 facets (interpersonal, affective, lifestyle), whereas the other 3 facets generally failed to demonstrate incremental validity relative to the antisocial facet. Because summed composite scores do not account for ordinal item distributions, the 6 Walters et al. (2008) samples were reanalyzed with factor score composites derived from a 4-factor confirmatory factor analysis.
