目的·探索新型冠状病毒肺炎心理应激调查问卷用于测评疫情相关急性应激反应的信度及效度。方法·2020年1月31日—2020年2月29日，向253名于上海交通大学医学院附属精神卫生中心门诊就诊患者、家属及医务人员施测新型冠状病毒肺炎心理应激调查问卷（COVID-19 Peritraumatic Distress Index，CPDI）及患者健康问卷抑郁量表（Patient Health Questionnaire-9，PHQ-9）、广泛性焦虑量表（General Anxiety Disorder-7，GAD-7）、心理健康自评问卷（Self-reporting Questionnaire-20，SRQ-20），同时通过舒辅智慧心理测试平台在线对全国75 867名被试施测CPDI。采用克龙巴赫α系数（Cronbach's α coefficient，Cronbach's α）评估量表的信度。同时对CPDI与PHQ-9、GAD-7及SRQ-20的相关性进行效标效度检验，用探索性因素分析检测结构效度，并检测其筛查新型冠状病毒肺炎疫情心理应激症状的分界值。结果·15项CPDI问卷信度分析结果显示Cronbach's α 为 0.932。该问卷与PHQ-9、GAD-7、SRQ-20的相关系数分别为0.670、0.699、0.711（均P=0.000）。探索性因子分析结果包含4个因子，因子负荷为0.491~0.681，累积方差解释率为72.006%。判别为可疑存在症状，分界值为10分，灵敏度和特异度分别为0.822、0.811；判别为确定存在症状，分界值为14分，灵敏度和特异度分别为0.815、0.824。结论·新型冠状病毒肺炎心理应激调查问卷的内部一致性信度、效标效度及结构效度良好。

·To explore the reliability and validity of Corona Virus Disease 2019 (COVID-19) Peritraumatic Distress Index (CPDI) in evaluating pandemic-related acute stress reaction.
·From 31 January 2020 to 29 February 2020, CPDI, Patient Health Questionnaire-9 (PHQ-9), General Anxiety Disorder-7 (GAD-7) and Self-reporting Questionnaire-20 (SRQ-20) were measured in 253 outpatients, their family members and medical staff of our hospital. At the same time, leveraging the Siuvo Intelligent Psychological Assessment Platform, we presented QR codes of the CPDI questionnaire online openly, accessible to the participants nationwide, and received a total of 75 867 valid responses. Cronbach's α coefficient was used to evaluate the internal consistency. The correlation between CPDI and PHQ-9, GAD-7 and SRQ-20 was used to test the criterion validity. Exploratory factor analysis was used to detect the structural validity and the cut-off score of the questionnaire to screen the psychological symptoms associated with COVID-19 was also detected.
·The Cronbach's α of the 15-item questionnaire was 0.932. The correlation coefficients between the 15-item CPDI and PHQ-9, GAD-7 and SRQ-20 were 0. 670, 0.699 and 0.711 respectively (all P=0.000). The exploratory factor analysis results contained 15 items and 4 factors, the factor load was 0.491-0.681, and the cumulative variance interpretation rate was 72.006%. In terms of cut-off score, it was identified as suspicious symptom by cut-off score of 10/11 points. The sensitivity and specificity were 0.822 and 0.811, respectively. The cut-off score to confirm the presence of symptoms was 14/15 points. The sensitivity and specificity were 0.815 and 0.824, respectively.
·The study indicates that CPDI is with good internal consistency reliability, criterion validity and structural validity.
