Aggression is a common problem in psychiatric and correctional facilities. An actuarial instrument, the Classification of Violence Risk (COVR), has demonstrated utility in predicting community aggression among civilly committed psychiatric patients and, more recently, an ability to predict institutional aggression in a forensic facility. This prospective study aimed to extend validation of the use of the COVR in a forensic facility.
The study, conducted at a large U.S. forensic facility, used nursing records to document incidents of physical aggression by 146 patients for 20 weeks after COVR administration. Correlational and chi square analyses were conducted to evaluate the efficacy of the COVR in predicting aggression.
The COVR showed modest predictive ability for institutional aggression, with a correlation of .331 and an area under the curve of .725.
Results support use of the COVR in a forensic facility; its ability to predict institutional aggression is similar to that found for community aggression.
攻击行为是精神科和管教机构中的常见问题。一种计算工具，即暴力风险分类（COVR），已证明可用于预测民事精神病患者的社区攻击行为，最近还具有预测法医机构内机构攻击行为的能力。本前瞻性研究旨在扩大 COVR 在法医机构中的使用验证。
该研究在美国一家大型法医机构进行，使用护理记录在 COVR 给药后 20 周内记录 146 名患者的身体攻击事件。进行相关和卡方分析以评估 COVR 预测攻击行为的功效。
COVR 对机构攻击行为具有适度的预测能力，相关系数为.331，曲线下面积为.725。
结果支持在法医机构中使用 COVR；它预测机构攻击行为的能力与预测社区攻击行为的能力相似。
