Persistence and Potential Lethality in Intimate Partner Violence: Evaluating the Concurrent and Predictive Validity...

This study seeks to determine the concurrent and predictive validity of a dual risk assessment protocol. It combines the risk of persistence in intimate partner violence (IPV) measured via the Domestic Violence Screening Instrument-Revised (DVSI-R) with supplemental items from the Danger Risk Assessment (DRA) bearing on the risk of potential lethality. We further test whether this assessment protocol reproduces disparities by race and ethnicity found in the larger population. Using a sample of 4,665 IPV male defendants with a female victim, analyses support both types of criterion validity. The DRA risk score is associated with felony charges, incarceration at the initial arrest, and the frequency of subsequent dangerous behavior. Results also suggest minimal predictive bias or disparate impact by race and ethnicity. Incorporating supplemental items bearing on potential lethality risk adds important information concerning the risk management strategies of those involved in IPV.
