This research is an examination of the predictive validity of the Lethality Screen, a tool used in conjunction with the Lethality Assessment Program (LAP). This intimate partner violence (IPV) risk assessment is an 11-item version of the Danger Assessment (DA) that was designed to be user-friendly for first responders and to maximize sensitivity. Participants ( N = 254) were recruited into the study at the scene of police-involved IPV incidents in one Southwestern state and subsequently participated in two structured telephone interviews approximately 7 months apart. These analyses provide evidence that the Lethality Screen has considerable sensitivity (92%-93%) and a high negative predictive value (93%-96%) for near lethal and severe violence. However, specificity was low (21%). The Lethality Screen also has good agreement with the DA and IPV survivors' perception of risk. The high sensitivity and low specificity should be considered carefully when determining whether the Lethality Screen is appropriate for particular areas of practice with IPV survivors and/or perpetrators.
本研究旨在检验致死性筛查工具的预测效度，该工具与致死性评估项目（LAP）结合使用。这种亲密伴侣暴力（IPV）风险评估是危险评估（DA）的11项版本，旨在方便急救人员使用并最大限度提高敏感性。研究人员在西南部一个州涉及警方的IPV事件现场招募了参与者（N = 254），随后他们大约相隔7个月参加了两次结构化电话访谈。这些分析表明，致死性筛查对于近乎致命和严重暴力具有相当高的敏感性（92%-93%）和较高的阴性预测值（93%-96%）。然而，特异性较低（21%）。致死性筛查与危险评估以及IPV幸存者的风险认知也具有良好的一致性。在确定致死性筛查是否适用于IPV幸存者和/或施暴者的特定实践领域时，应仔细考虑其高敏感性和低特异性。
