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.
本研究评估了爱荷华州暴力与受害情况工具中的项目和量表在来自爱荷华州的1961名处于缓刑期或从监狱释放后接受假释监督的男性样本中的效用。这是第一项检验爱荷华州暴力与受害情况工具预测刑事犯罪可能性的研究。这些男性在进入缓刑或假释期后立即被跟踪了30个月。曲线下面积分析表明，爱荷华州暴力与受害情况工具对暴力和受害指控具有中等至良好的预测能力，但对毒品犯罪只有随机预测能力。值得注意的是，该工具的两个量表在30个月的随访中表现同样出色。爱荷华州暴力与受害情况工具中的项目不仅能预测暴力行为，而且评分简单明了。文中讨论了与当前研究结果相关的暴力管理策略，包括将该测量方法扩展到其他司法管辖区和人群的可能性。
