Posttraumatic stress disorder (PTSD) is a significant public health concern associated with marked impairment across the lifespan. Exposure to traumatic events alone, however, is insufficient to determine if an individual has PTSD. PTSD is a heterogeneous diagnosis such that assessment of all 20 symptoms is problematic in time-limited treatment settings. Brief assessment tools that identify those at risk for PTSD and measure symptom severity are needed to improve access to care and assess treatment response. The present study evaluated abbreviated measures of PTSD symptoms derived from the PTSD Checklist for DSM-5 (PCL-5) - a 20-item validated measure of PTSD symptoms - across two studies. In the first, using a community sample of adults exposed to a traumatic event, 4-and 8-item versions of the PCL-5 were identified that were highly correlated with the full PCL-5. In the second, using a sample of combat veterans, the 4-and 8-item measures had comparable diagnostic utility to the total-scale PCL-5. These results provide support for an abbreviated measure of the PCL-5 as an alternative to the 20-item total scale.
创伤后应激障碍（PTSD）是一个严重的公共卫生问题，会在整个生命周期中导致明显的损伤。然而，仅仅接触创伤性事件本身并不能确定一个人是否患有 PTSD。PTSD 是一种异质性的诊断，因此在有限的治疗环境中评估所有 20 种症状是有问题的。需要简短的评估工具来识别那些有 PTSD 风险的人，并衡量症状的严重程度，以改善获得治疗的机会并评估治疗反应。本研究在两项研究中评估了源自 PTSD 检查表 DSM-5（PCL-5）的 PTSD 症状的简化测量方法，这是一种经过验证的 PTSD 症状 20 项测量方法。在第一项研究中，使用暴露于创伤性事件的成人社区样本，确定了与完整 PCL-5 高度相关的 PCL-5 的 4 项和 8 项版本。在第二项研究中，使用参战退伍军人样本，4 项和 8 项测量方法与总量表 PCL-5 具有相当的诊断效用。这些结果支持将 PCL-5 的简化测量作为 20 项总量表的替代方法。
