摘要
目的：像其他急救人员一样，许多消防员表现出创伤后应激障碍（PTSD）的迹象，而这些症状往往无法确诊。开发方便、简单和有效的筛查工具可以提高识别和服务利用率。《精神疾病诊断与统计手册-第五版》(PCL-5；PC-PTSD-5[0-20]在消防员中表现出良好的筛选效果。本研究将PC-PTSD-5[0-20]翻译成土耳其文，并进行了效度和信度分析。方法：将PC-PTSD-5[0-20]通过前向翻译、后向翻译和专家指导下的细化，进行文化改编。我们对30名消防员进行了试点测试，随后对伊斯坦布尔所有地区消防站的215名消防员进行了全面研究。在整个研究中，参与者完成了土耳其PC-PTSD-5[0-20]和PCL-5，我们分析了它们的信度、效度和诊断效用。结果：土耳其PC-PTSD-5[0-20]表现出良好的心理测量特性：可接受的内部一致性（α = .61）；重测信度高（r = 0.88, p < 0.001）；与PCL-5有较强的收敛效度（r = 0.81, p < 0.001）。受试者工作特征分析显示，曲线下面积为0.947，最佳临界值为9，平衡了较高的准确性（90.23%）、敏感性（82.86%）和特异性（91.67%），而样本中PTSD患病率估计为16.3%。结论：土耳其PC-PTSD-5[0-20]显示出强大的心理测量特性，具有较高的准确度（临界值为9分），对筛查消防员的PTSD具有出色的诊断效用。未来的研究应探索其在其他第一响应者群体中的适用性以及在纵向研究中的预测效度。（PsycInfo Database Record (c) 2025 APA，版权所有）。
Screening for PTSD in first responders: Turkish adaptation and psychometric validation of the primary care PTSD screen for DSM-5.
Objective: Like other first responders, many firefighters show signs of posttraumatic stress disorder (PTSD) that often go undiagnosed. Developing accessible, brief, and efficient screening tools may improve identification and service utilization. The most recent adaptation of the Primary Care PTSD Checklist for the Diagnostic and Statistical Manual of Mental Disorders-Fifth Edition (PCL-5; PC-PTSD-5 [0-20]) demonstrates promising screening performance among firefighters. Our study translated the PC-PTSD-5 [0-20] into Turkish and conducted validity and reliability analyses.
Method: The PC-PTSD-5 [0-20] was translated and culturally adapted into Turkish through forward translation, backward translation, and expert-led refinement. We conducted a pilot test with 30 firefighters, followed by carrying out the full study among (N = 215) firefighters from fire stations across all the districts of Istanbul. Participants in the full study completed the Turkish PC-PTSD-5 [0-20] and PCL-5, and we analyzed them for reliability, validity, and diagnostic utility.
Results: The Turkish PC-PTSD-5 [0-20] demonstrated favorable psychometric properties: acceptable internal consistency (α = .61); high test-retest reliability (r = 0.88, p < .001); and strong convergent validity with PCL-5 (r = 0.81, p < .001). Receiver operating characteristic analysis revealed an area under the curve of 0.947 with an optimal cutoff score of 9 that balanced high accuracy (90.23%), sensitivity (82.86%), and specificity (91.67%), while PTSD prevalence was estimated at 16.3% in the sample.
Conclusions: The Turkish PC-PTSD-5 [0-20] demonstrates strong psychometric properties, with high accuracy at a cutoff score of 9, and excellent diagnostic utility for screening PTSD among firefighters. Future research should explore its applicability to other first responder groups and predictive validity in longitudinal studies. (PsycInfo Database Record (c) 2025 APA, all rights reserved).
期刊介绍：
Psychological Trauma: Theory, Research, Practice, and Policy publishes empirical research on the psychological effects of trauma. The journal is intended to be a forum for an interdisciplinary discussion on trauma, blending science, theory, practice, and policy.
The journal publishes empirical research on a wide range of trauma-related topics, including:
-Psychological treatments and effects
-Promotion of education about effects of and treatment for trauma
-Assessment and diagnosis of trauma
-Pathophysiology of trauma reactions
-Health services (delivery of services to trauma populations)
-Epidemiological studies and risk factor studies
-Neuroimaging studies
-Trauma and cultural competence
