Abstract

The present study is a first-time evaluation of the Violence Risk Appraisal Guide's (VRAG) predictive quality for institutional violence in a German-speaking country. The VRAG was assessed for 106 violent and sexual offenders based on their files. Violent infractions during imprisonment were evaluated using the files of the state penitentiary. Results show in accordance with previous studies only a moderate effect between VRAG scores and institutional misconduct. However, these findings were only significant for participants with a sex crime as index offense. In the study, the VRAG was unable to predict verbal and physical violence by violent offenders. The implications of these findings for institutional risk management and the future development of intramural detection of participants at risk in the German-speaking part of Europe are discussed.

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
