ODARA - Ontario Domestic Assault Risk Assessment

Domestic Violence and Abuse in Relationships


Our domestic violence research is headed by Dr. Zoe Hilton, and involves our research team and collaborators in the Province of Ontario, across Canada, and the United States.

The principal products of this research are the Ontario Domestic Assault Risk Assessment (ODARA) and Domestic Violence Risk Appraisal Guide (DVRAG). These tools comprise a coherent actuarial system that assesses how likely a man is to assault his partner again, and how his risk compares with that of other domestic offenders. These tools also predict the speed and number of recidivistic offenses and the severity of injuries caused. The ODARA is suitable for use in any setting responding to domestic violence victims or offenders. The DVRAG is intended for use by forensic clinicians and criminal justice officials who can access in-depth information. The item instructions for both are kept as close as possible to the original research coding criteria.
