This study examined the predictive properties of the Ontario Domestic Assault Risk Assessment (ODARA) in a large Canadian, predominantly Indigenous, sample from a geographic region with the highest rates of intimate partner violence (IPV) in the country. A random stratified sample of 300 men (92.7% Indigenous) court adjudicated for an IPV offense was drawn from six Northern Saskatchewan Royal Canadian Mounted Police detachment regions. The ODARA was rated from police records and recidivism data were obtained via official criminal records over a mean 4.7-year follow-up. ODARA scores had small to moderate predictive accuracy (AUC/C = .58–.67) for IPV and other recidivism outcomes in the aggregate sample and Indigenous subsample. E/O index analyses demonstrated that the ODARA Ontario norms overpredicted IPV recidivism at high scores but underpredicted it at lower mid-range scores. Implications for use of the ODARA to assist frontline police personnel in IPV risk assessment and management are discussed.

本研究在来自加拿大亲密伴侣暴力 (IPV) 发生率最高的地理区域的大型加拿大（主要是原住民）样本中检查了安大略省家庭袭击风险评估 (ODARA) 的预测特性。从六个北萨斯喀彻温省加拿大皇家骑警支队地区抽取了 300 名因 IPV 犯罪而被裁定的男性（92.7% 土著）法院的随机分层样本。ODARA 是从警方记录中评定的，再犯数据是通过平均 4.7 年随访的官方犯罪记录获得的。ODARA 评分对聚合样本和土著子样本中的 IPV 和其他累犯结果具有小到中等的预测准确度 (AUC/C = .58–.67)。E/O 指数分析表明，安大略省 ODARA 规范在高分时高估了 IPV 累犯，但在中低分时低估了它。讨论了使用 ODARA 协助前线警务人员进行 IPV 风险评估和管理的意义。
