The current study compares the total scores of two potential posttraumatic stress disorder (PTSD) screening tools, the Impact of Event Scale (IES) and the PTSD Symptom Scale, Self-Report (PSS-SR), to the Clinician-Administered PTSD Scale (CAPS) in a large sample of motor vehicle accident (MVA) survivors (N = 229, of whom 43% met criteria for PTSD). For the IES using a cutoff score of 27, sensitivity was .91, specificity was .72, and overall correct classification was .80. For the PSS-SR using a cutoff score of 14, sensitivity was .91, specificity was .62, and overall correct classification was .74. Compared to those in studies of other trauma populations, the identified IES cutoff score is somewhat lower for this population of MVA survivors and the identified PSS-SR cutoff score is consistent with previous findings. These data support the use of the IES and the PSS-SR as PTSD screening tools in MVA samples.
本研究在大量机动车事故（MVA）幸存者样本（N = 229，其中43%符合创伤后应激障碍（PTSD）标准）中，将两种潜在的PTSD筛查工具——事件影响量表（IES）和PTSD症状量表自评版（PSS-SR）的总分，与临床医生实施的PTSD量表（CAPS）进行比较。对于IES，采用临界值27时，敏感性为0.91，特异性为0.72，总体正确分类率为0.80。对于PSS-SR，采用临界值14时，敏感性为0.91，特异性为0.62，总体正确分类率为0.74。与其他创伤人群的研究相比，本MVA幸存者人群中确定的IES临界值略低，而确定的PSS-SR临界值与先前研究结果一致。这些数据支持将IES和PSS-SR用作MVA样本中的PTSD筛查工具。
