本研究通过对美国398名成年亚马逊MTurk员工的在线调查，检验了冠状病毒焦虑量表(CAS)的心理测量特性。验证性因素分析表明，CAS测量了一个可靠的(α=0.92)一维结构，其结构被证明在性别、种族和年龄之间是不变的。结构效度与CAS得分与人口统计学、冠状病毒诊断、焦虑史、冠状病毒恐惧、功能障碍、酒精/药物应对、宗教应对、绝望、自杀意念以及社会态度(例如，对特朗普总统的满意度)之间的相关性被证明。CAS对功能损害的辨别能力也很强(AUC=0.88)，而原始截断分>；=9(敏感性为76%，特异性为90%)对功能损害的诊断效果最强。总体而言，这些发现与中科院第一次调查的结果基本一致，支持了该心理健康筛查器对新冠肺炎相关研究和实践的有效性。
The present study examined the psychometric properties of the Coronavirus Anxiety Scale (CAS) using an online survey of 398 adult Amazon MTurk workers in the U.S. Confirmatory factor analyses demonstrated that the CAS measures a reliable (alpha = 0.92), unidimensional construct with a structure that was shown to be invariant across gender, race, and age. Construct validity was demonstrated with correlations between CAS scores and demographics, coronavirus diagnosis, history of anxiety, coronavirus fear, functional impairment, alcohol/drug coping, religious coping, hopelessness, suicidal ideation, as well as social attitudes (e.g., satisfaction with President Trump). The CAS also demonstrated solid discrimination ability for functional impairment (AUC = 0.88), while the original cut score of >= 9 (76% sensitivity and 90% specificity) showed the strongest diagnostic effectiveness among scores. Overall, these findings are largely consistent with the results of the first CAS investigation and support the validity of this mental health screener for COVID-19 related research and practice.
