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 (α = 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.
本研究通过对美国 398 名亚马逊土耳其机器人（MTurk）成年员工的在线调查，考察了冠状病毒焦虑量表（Coronavirus Anxiety Scale，CAS）的心理测量学特性。验证性因素分析表明，CAS 测量的是一种可靠的（α=0.92）、单维度结构，其结构在性别、种族和年龄上均具有不变性。与 CAS 得分相关的人口统计学、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（如对特朗普总统的满意度），证明了其结构效度。CAS 对功能障碍也具有良好的判别能力（AUC=0.88），而≥9 分（76%的敏感性和 90%的特异性）的原始截断分数在所有分数中显示出最强的诊断效果。总体而言，这些结果与 CAS 的首次调查结果基本一致，支持该心理健康筛查器用于与 COVID-19 相关的研究和实践的有效性。
