Battered women's perceptions of risk versus risk factors and instruments in predicting repeat reassault

This study partially replicates and expands on a previous study that showed women's perceptions of risk to be a strong predictor of reassault among batterers. The current study employed a larger and multisite sample, a longer follow-up period of 15 months, and multiple outcomes including "repeated reassault" (n = 499). According to the multinomial logistic regressions, women's perceptions of risk improved prediction with risk factors (ROC area under the curve improved by.04 and sensitivity of repeated reassault increased 12 percentage points). In comparison to simulated risk instruments, women's perceptions by themselves were better predictors than the K-SID, similar in predictive ability to the SARA, and almost as strong as the DAS. The best prediction of repeated reassault was obtained using risk markers, including women's perceptions (ROC AUC =.83; 70% sensitivity) or by using the DAS and women's perceptions together (ROC AUC =.73; 64% sensitivity).
