Physical symptoms are highly comorbid with posttraumatic stress disorder (PTSD). As PTSD is underdiagnosed, this study explored the value of self-reported physical symptoms in screening for 30-day PTSD in military personnel. Two physical symptom scales were constructed using items from a 67-item health symptom checklist, clinical interviews were used as the diagnostic reference standard, and diagnostic utility of physical symptoms was compared with the current gold standard screen, the PTSD checklist (PCL). Receiver operating characteristic analyses showed that both a 9-item and a 10-item physical symptom scale were of value in predicting PTSD (areas under the curve 0.81 and 0.85). Importantly, two thirds of PTSD positive personnel missed by the PCL were captured with physical symptoms scales, and when physical symptoms were added to the PCL, prediction was improved (areas under the curve 0.90 to 0.92). Our findings highlight the value of including assessing physical symptoms in PTSD screening.
身体症状与创伤后应激障碍（PTSD）高度共病。由于 PTSD 诊断不足，本研究探讨了自我报告的身体症状在筛选军人 PTSD 30 天的价值。使用来自 67 项健康症状检查表的项目构建了两个身体症状量表，临床访谈用作诊断参考标准，并将身体症状的诊断效用与当前的黄金标准筛查工具，即 PTSD 检查表（PCL）进行了比较。受试者工作特征分析表明，9 项和 10 项身体症状量表在预测 PTSD 方面均具有价值（曲线下面积分别为 0.81 和 0.85）。重要的是，PCL 漏诊的三分之二 PTSD 阳性人员可通过身体症状量表捕捉到，并且当将身体症状添加到 PCL 中时，预测得到了改善（曲线下面积从 0.90 增加到 0.92）。我们的研究结果强调了在 PTSD 筛查中评估身体症状的重要性。
