Using the Violence Risk Appraisal Guide (VRAG) to predict in-prison aggressive behavior in a Swiss offender population.
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.
