BACKGROUND
The Posttraumatic Stress Disorder Checklist (PCL) is a valid and reliable self-report measure for the assessment of Posttraumatic Stress Disorder (PTSD). Recently the PCL was updated according to the DSM-5 criteria for PTSD. So far only a few studies have examined the psychometric properties of the PCL-5, and all of these are restricted to populations living in industrialized countries. The aim of this study was to determine the psychometric properties and diagnostic utility of the PCL-5 as a screening instrument for war-affected displaced Kurdish and Arab populations. The specific goal was to determine a contextually valid cut-off score for a probable diagnosis of PTSD.
METHODS
The PCL-5 was translated into Arabic and two Kurdish dialects. Trained interviewers administered these translations as assisted self-reports to 206 adults living in camps for displaced people in Iraq, together with depression and war-exposure instruments. Two weeks later, 98 randomly chosen subjects were reassessed by expert clinical psychologists. In the absence of a gold-standard instrument with proven validity in this context, the expert interviewers applied the PCL-5 items in the form of a clinical interview and used a DSM-5-algorithm to determine a diagnosis of PTSD. Receiver operator characteristics (ROC) were performed to determine a valid cutoff-score.
RESULTS
The internal consistency of the PCL-5 was high (alpha = .85) and the instrument showed an adequate convergent validity. Using the cut-off score of 23, the PCL-5 achieved the optimal balance of sensitivity and specificity (area under the curve = .82, p < .001; sensitivity = .82, specificity = .70).
CONCLUSIONS
Given that the comparison of the two assessments included both a re-test interval and validation by different interviewers, our results indicate that the PCL-5 can be recommended as an assessment and screening instrument for Kurdish and Arab populations.
背景
创伤后应激障碍检查表（PCL）是一种有效的、可靠的自评工具，用于评估创伤后应激障碍（PTSD）。最近，PCL 根据 DSM-5 对 PTSD 的标准进行了更新。到目前为止，只有少数研究检查了 PCL-5 的心理测量特性，所有这些研究都仅限于生活在工业化国家的人群。本研究的目的是确定 PCL-5 作为一种筛查工具，用于评估受战争影响的库尔德和阿拉伯流离失所人群的心理测量特性和诊断效用。具体目标是确定一个与语境相关的可能 PTSD 诊断的切点分数。
方法
PCL-5 被翻译成阿拉伯语和两种库尔德方言。经过培训的访谈者向居住在伊拉克流离失所者营地的 206 名成年人提供了这些翻译，并结合抑郁和战争暴露工具进行了辅助自评。两周后，随机选择 98 名受试者由专业临床心理学家进行重新评估。在缺乏在这种情况下具有有效性验证的黄金标准工具的情况下，专业访谈者以临床访谈的形式应用 PCL-5 条目，并使用 DSM-5 算法来确定 PTSD 的诊断。进行接收者操作特征（ROC）以确定有效的切点分数。
结果
PCL-5 的内部一致性很高（α=0.85），该工具表现出足够的收敛效度。使用 23 的截断分数，PCL-5 实现了敏感性和特异性的最佳平衡（曲线下面积=0.82，p<0.001；敏感性=0.82，特异性=0.70）。
结论
鉴于两次评估的比较包括重测间隔和不同访谈者的验证，我们的结果表明 PCL-5 可以推荐作为库尔德和阿拉伯人群的评估和筛查工具。
