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.

Violent Recidivism

The Ontario Domestic Assault Risk Assessment (ODARA) is an actuarial risk assessment tool for intimate partner violence (IPV) recidivism. Despite its international use, there is no published validation of the ODARA’s predictive accuracy in a U.S. sample. We studied 356 men in New York police records of IPV against a female partner to examine the ODARA’s predictive accuracy for IPV recidivism (base rate 35%), non-IPV violent recidivism (against a nonpartner; 16%), any violent recidivism (49%), and nonviolent recidivism (50%), in a fixed 2-year follow-up. Using 11 scorable ODARA items, area under the curve values were significant and ranged from .590 to .630, indicating small to medium effects. Expected/Observed indices revealed poor calibration with 2-year IPV recidivism rates in ODARA construction and cross-validation samples. Findings support the generalization of the ODARA’s predictive accuracy in different populations and outcomes, but a need for new norm development for higher risk populations.

This study examines the predictive accuracy of three risk assessment approaches for intimate partner violence (IPV) among a sample of 246 male perpetrators who were charged for offenses against their intimate partners. The sample was followed up for an average of 3.3 years, and any new general, violent, and IPV charges and convictions were recorded. The Ontario Domestic Assault Risk Assessment (ODARA) and a modified 14-item version of the Spousal Assault Risk Assessment Guide (SARA) demonstrated large effects in their ability to predict any reoffending or any violent reoffending and moderate predictive accuracy for IPV offending behaviors. The regionally used approach, Family Violence Investigative Report (FVIR), showed good predictive validity for any future offending but poorly predicted any of the violent-specific recidivism outcomes. Results of the study show that the ODARA was significantly better at predicting violence risk over the FVIR, but paired comparisons did not reveal statistical differences with the SARA.

Risk Principle

To incorporate evidence-based practices into batterer intervention programs (BIPs), some intimate partner violence (IPV) researchers have begun to explore the integration of the principles of effective intervention (PEI) into BIPs. The PEI risk principle states that programs should assess offenders' risk for recidivism, and then match offenders' risk levels to the intensity of treatment and other interventions. Therefore, this study demonstrates how BIPs can use the Ontario Domestic Assault Risk Assessment (ODARA) to guide treatment intensity decisions for IPV offenders. Using data from men with criminal charges for IPV incidents in the original ODARA construction and validation research (N = 970), we illustrate how low, medium, and high categories can be created and used to inform BIP treatment intensity decisions (as outlined by the risk principle). Results indicate the ODARA can be used to inform a three-tiered categorical system for BIPs, in accordance with the risk principle of the PEI. Study results provide an avenue for BIP service providers to consider when determining treatment intensity for its IPV offenders. Suggestions for future research are also provided.

Australian Sample

This article describes a prospective validation of the Ontario Domestic Assault Risk Assessment (ODARA) in an Australian sample of 854 family violence cases presenting to police over a 5-month period in 2015. Two hundred cases met inclusion criteria for administration of the ODARA (male-to-female intimate partner violence with a history of assault and cohabitation). The ODARA performed well in predicting further intimate partner physical assault (area under the curve [AUC] = .68), and in predicting the outcome of any further police contact for nonphysical intimate partner abuse (AUC = .72). Despite these positive results, the instrument’s restrictive inclusion criteria meant that it could be appropriately applied in only 23% of family violence cases reported to police during the data collection period, limiting its practicality in this setting.

Domestic Assault

This study examined the psychometric, predictive, and dynamic properties of intimate partner violence (IPV) risk. The sample consisted of 88 men attending an outpatient IPV correctional program. The Ontario Domestic Assault Risk Assessment (ODARA) was rated at pretreatment using participant files. The Spousal Assault Risk Assessment–Version 3 (SARA-V3) was rated at pre- and posttreatment using collateral information (e.g., facilitator ratings, files) and participant questionnaires. Recidivism data were obtained from a court database with an average follow-up of 15 months. The SARA-V3 and ODARA demonstrated strong convergent validity and predicted violent and general recidivism with moderate to high accuracy; SARA-V3 posttreatment ratings incremented the ODARA in the prediction of recidivism, yet not vice versa. Noncompleters were higher risk and had higher recidivism rates. Changes on the SARA-V3’s Perpetrator Risk Factors domain were significantly associated with decreased recidivism in bivariate analyses and some change associations remained significant with stringent controls for risk. Implications for risk assessment/management, service planning, and future research are discussed.

Total Cohort

Intimate partner violence (IPV) is a major public health issue; worldwide, almost 1 in 3 women is affected. Police involvement in IPV cases has substantially increased because of “proarrest” and “procharging” policies and the enforcement of laws protecting victims of domestic violence. In the course of these changes, several front-line instruments have been developed to structure police risk assessment and decision-making strategies in such cases. One of those is the Ontario Domestic Assault Risk Assessment (ODARA). To investigate its validity in a Swiss police setting, a total cohort of male IPV offenders was retrospectively assessed for a fixed time at risk of 5 years. The recidivism base rate was 32% when recidivism was defined as subsequent police-registered IPV. Although ODARA scores were significantly correlated with IPV recidivism, they showed poor discrimination and calibration. Despite comparable base rates of recidivism, the Zurich sample scored significantly higher on the ODARA than the development sample. This mismatch of the expected and observed recidivism rates resulted in an overestimating of risk, especially in the two highest risk bins. Several reasons for those deviations, such as level of intervention, victim’s reporting behavior, and the dynamic nature of IPV, are discussed.

Roc Area

Female perpetrators of assault against dating, cohabiting, or marital partners (intimate partner violence [IPV]) recidivate less than their male counterparts. Risk assessment instruments, though, have been developed almost exclusively on men. In a prospective, masked 9-year follow up of 30 female IPV offenders incarcerated in a correctional treatment institution within one decade, the base rate of IPV recidivism was 23%. The Ontario Domestic Assault Risk Assessment (ODARA) predicted IPV recidivism, receiver operating characteristic (ROC) area = .724, 95% confidence interval (CI) = [0.503, 0.944], but recidivism rates differed significantly from rates based on male samples. Gender-modified items did not improve prediction. We recommend further research with larger samples to seek improved recidivism estimates among female IPV offenders, but in the interim, we suggest the ODARA can be used to apportion intervention resources for female IPV perpetrators.
