: Peritraumatic distress as assessed by the (PDI), has been consistently shown to predict the development of Posttraumatic Stress Disorder (PTSD) after the exposure to a potentially traumatizing event. : The present study aims to validate the Italian version of the PDI in a sample of Healthcare Workers (HCWs) exposed to COVID-19 related potentially traumatizing events. : = 265 HCWs who repeatedly experienced the deaths of patients during COVID-19 emergency in Italy, were enrolled from the Azienda Ospedaliero-Universitaria Pisana (Pisa, Italy). They completed the PDI, Impact Event Scale - revised (IES-R) and the Trauma and Loss Spectrum - Self Report (TALS-SR) domain. : Internal consistency was good with a Cronbach's alpha coefficient was .874. The PDI correlated strongly with measures that was conceptually close (TALS-SR domain; = .723, < .001). Participants who scored above the cut-off for PTSD reported significantly higher PDI scores than those who did not (6.47 ± 5.25 vs. 19.11 ± 8.291, < 0.001). The one-month test-retest reliability ( = 21) was excellent (ICC = .997). Finally, factor analyses revealed that the PDI exhibited a single-factor structure. : the Italian version of the PDI showed good psychometric proprieties and may be used to detect those at risk for developing PTSD.
通过创伤事件量表（PDI）评估的创伤时困扰，一直被证明能够预测在经历潜在创伤性事件后创伤后应激障碍（PTSD）的发生。本研究旨在验证创伤事件量表意大利语版本在接触与新冠疫情相关潜在创伤性事件的医护人员（HCWs）样本中的有效性。从比萨大学医院（意大利比萨）招募了265名在意大利新冠疫情紧急情况期间反复经历患者死亡的医护人员。他们完成了创伤事件量表、修订版冲击事件量表（IES-R）以及创伤与丧失谱-自我报告（TALS-SR）领域的测评。内部一致性良好，克朗巴哈α系数为0.874。创伤事件量表与概念上相近的测评指标（TALS-SR领域；r = 0.723，p < 0.001）密切相关。PTSD得分高于临界值的参与者报告的创伤事件量表得分显著高于未高于临界值的参与者（6.47 ± 5.25对19.11 ± 8.291，p < 0.001）。为期一个月的重测信度（n = 21）极佳（组内相关系数ICC = 0.997）。最后，因子分析表明创伤事件量表呈现单因素结构。创伤事件量表意大利语版本显示出良好的心理测量学特性，可用于检测有患PTSD风险的人群。
