Predicting violence risk and recidivism in female parolees: A state-wide sample.

Historically, research on violence risk assessments has primarily focused on male psychiatric patients and/or inmates, with minimal attention given to female patients and/or inmates-two populations likely to differ with regard to violence risk conceptualization. To date, there is no known measure of violence risk specifically tailored to predicting risk for this population that is accurate, brief, and cost-effective. As such, the current study exclusively focused on the predictive ability of the Iowa Violence and Victimization Instrument (IVVI) for female parolees over a 30-month follow-up period. Results indicated not only was the IVVI comparable across genders, its predictive power was comparable to more established measures (i.e., Violence Risk Appraisal Guide-Revised, HCR-20 V3). Results also found the IVVI may have greater usefulness with prediction of violent and felony property offenses, but limited usefulness for predicting misdemeanor property and drug offenses. Taken together, findings gathered from the current study suggest while women are reoffending at lower rates than men, yet there are fewer gender differences in risk factors for engaging in violence than expected.

Predicting violence and recidivism in a large sample of males on probation or parole.

This study evaluated the utility of items and scales from the Iowa Violence and Victimization Instrument in a sample of 1961 males from the state of Iowa who were on probation or released from prison to parole supervision. This is the first study to examine the potential of the Iowa Violence and Victimization Instrument to predict criminal offenses. The males were followed for 30months immediately following their admission to probation or parole. AUC analyses indicated fair to good predictive power for the Iowa Violence and Victimization Instrument for charges of violence and victimization, but chance predictive power for drug offenses. Notably, both scales of the instrument performed equally well at the 30-month follow-up. Items on the Iowa Violence and Victimization Instrument not only predicted violence, but are straightforward to score. Violence management strategies are discussed as they relate to the current findings, including the potential to expand the measure to other jurisdictions and populations.
