The study assessed the discriminative validity and the predictive validity of several historical/actuarial risk assessments and dynamic/proximal risk assessments on inmates in community-based sites as well as security sites at the low, medium, and high risk security levels in England and Wales.
Abstract
Results indicate that the Violence Risk Appraisal Guide (VRAG), the Historical Scale (HCR-20-H), the Risk Matrix 2000-C, and the Emotional Problems Scales-Internalizing (EPS-Internalizing) discriminated between groups with participants from high security having higher scores than those in medium security, and those in medium security having higher scores that those in community based sites. The VRAG, all HCR-20 scales, the Short Dynamic Risk Scale, and the EPS–Internalizing and Externalizing showed significant areas under the curve for the prediction violence. The Static-99 showed a significant area under the curve for the prediction of sexual incidents. The discussion reviews the value of these various scales to intellectual disability services. A total of 212 participants from high, medium, and low risk security sites in England and Wales, including community-based sites, were compared using a range of risk assessment; all data were collected from clinical files. Patients were generally referred from prisons, secure hospitals, and the courts. Limitations were detailed. Tables, figures, references
