This study examined the psychometric properties of a Brazilian adapted version of the Coronavirus Anxiety Scale (CAS-BR) in a sample of adults in Brazil. Confirmatory factor analyses demonstrated that the CAS-BR produces a reliable (α = .84), unidimensional construct whose structure was shown to be invariant across gender, race, and age. However, some items of the CAS-BR were stronger indicators of the coronavirus anxiety construct for women and younger adults. Although the CAS-BR demonstrated evidence of discrimination ability for functional impairment (AUC = .77), Youden indexes were low to identify a clinical cut-score. Construct validity was demonstrated with correlations between CAS-BR scores and measures of functional impairment, generalized anxiety, and depression. Exploratory analyses revealed that CAS-BR total scores were higher among women and participants with a history of anxiety disorder. These findings are consistent with previous investigations and support the validity of CAS-BR for measuring coronavirus anxiety with Brazilian adults.
本研究在巴西成年人样本中检验了冠状病毒焦虑量表（CAS-BR）的巴西适应版本的心理测量特性。验证性因素分析表明，CAS-BR 产生了可靠的（α = .84）、单维结构，其结构在性别、种族和年龄上均具有不变性。然而，CAS-BR 的一些项目对女性和年轻成年人的冠状病毒焦虑结构具有更强的指示性。尽管 CAS-BR 对功能障碍（AUC = .77）的判别能力表现出了证据，但用于确定临床临界值的约登指数较低。与功能障碍、广泛性焦虑和抑郁的测量结果之间的相关性证明了结构效度。探索性分析显示，CAS-BR 总分在女性和有焦虑障碍病史的参与者中更高。这些发现与之前的研究一致，支持 CAS-BR 用于测量巴西成年人冠状病毒焦虑的有效性。
