到目前为止，很少有研究检查自我报告措施的能力，以评估症状严重程度和诊断状态的变化作为治疗的函数。本研究探讨了创伤后应激障碍（PTSD）检查表（PCL）的有效性作为一个衡量症状的变化程序化治疗后。97名越战老兵与战斗相关的PTSD的样本进行了评估，使用临床医生管理的PTSD量表（CAPS）和PCL之前，9个月后，参与PTSD治疗计划。使用CAPS作为PTSD诊断学的“金标准”，PCL在治疗前和治疗后表现出较高的诊断准确性。然而，PCL在每个时间点确定个体症状的存在和严重程度的能力在准确性方面存在显著差异。此外，随着症状从治疗前到治疗后的改善，并接近阈值标准，PCL显示诊断准确性降低。作为整体症状变化的指标，与CAPS相比，PCL低估了改善。结果支持在该人群中使用PCL的总体截止评分50进行诊断，症状标准的项目评分为3。2001 Elsevier Science Ltd.（C）保留所有权利。
Little research to date has examined the ability of self-report measures to assess changes in symptom severity and diagnostic status as a function of treatment. This study investigated the validity of the posttraumatic stress disorder (PTSD) checklist (PCL) as a measure of symptomatic change following programmatic treatment. A sample of 97 Vietnam veterans with combat-related PTSD was assessed using the clinician-administered PTSD scale (CAPS) and the PCL prior to, and 9 months following, participation in a PTSD treatment program. Using the CAPS as the "gold standard" measure of PTSD symptomatology, the PCL demonstrated high diagnostic accuracy pre- and posttreatment. However, significant variations in accuracy were evident in the ability of the PCL to determine the presence and severity of individual symptoms at each time point. In addition, as symptoms improved from pre- to posttreatment, and approached the threshold criteria, the PCL demonstrated reductions in diagnostic accuracy. As a measure of overall symptomatic change, the PCL underrated improvement in comparison to the CAPS. The results supported the use of an overall cut-off score of 50 on the PCL for a diagnosis, and an item score of 3 for symptom criterion, in this population. 2001 Elsevier Science Ltd.
