Post-traumatic stress disorder (PTSD) is prevalent but is under-detected and under-treated, despite available efficacious treatments. To improve detection rates, screening instruments such as the PTSD Checklist (PCL) and the Primary Care-PTSD (PC-PTSD) screen have been widely used. However, validation of these screening instruments among patients seeking treatment in substance use disorder (SUD) specialty treatment clinics and general mental health (MH) treatment clinics is limited. Therefore, this study assessed the area under the ROC curve (AUC), sensitivity, specificity, efficiency, and positive and negative predictive values of the PCL, PC-PTSD, and five abbreviated versions of the PCL in detecting PTSD among samples of patients seeking treatment in SUD specialty treatment (n=158) and general MH treatment settings (n=242). A computer-assisted structured diagnostic interview (C-DIS-IV) was used to ascertain patient DSM-IV PTSD diagnostic status. Based on the C-DIS-IV, prevalence of PTSD was found to be 36.7 and 52.9% in the SUD and MH samples, respectively. The PCL, PC-PTSD, and five abbreviated versions of the PCL were found to have adequate psychometric properties for screening patients in SUD (AUC ranged from 0.80 to 0.86) and MH (AUC ranged from 0.77 to 0.80) outpatient treatment settings.
创伤后应激障碍（PTSD）很常见，但尽管有有效的治疗方法，其检出率和治疗率仍然较低。为了提高检出率，人们广泛使用 PTSD 检查表（PCL）和初级保健 PTSD 筛查（PC-PTSD）等筛查工具。然而，这些筛查工具在物质使用障碍（SUD）专科治疗诊所和一般心理健康（MH）治疗诊所的患者中进行验证的情况有限。因此，本研究评估了 PCL、PC-PTSD 以及 PCL 的五个缩写版本在 SUD 专科治疗（n=158）和一般 MH 治疗环境（n=242）中接受治疗的患者样本中检测 PTSD 的受试者工作特征曲线（ROC）下面积（AUC）、敏感度、特异性、效率以及阳性和阴性预测值。使用计算机辅助结构化诊断访谈（C-DIS-IV）来确定患者 DSM-IV PTSD 诊断状况。根据 C-DIS-IV，SUD 和 MH 样本中的 PTSD 患病率分别为 36.7%和 52.9%。PCL、PC-PTSD 和 PCL 的五个缩写版本在 SUD（AUC 范围为 0.80 至 0.86）和 MH（AUC 范围为 0.77 至 0.80）门诊治疗环境中均具有足够的心理测量学特性。
