The aim of the study was to analyze the psychometric properties of the Spanish version of the (CAS), using Item Response Theory (IRT) and Confirmatory Factor Analysis (CFA). The participants were 790 Peruvians, selected through a convenience sampling, where the majority were women. The CFA models indicated that the one-dimensional structure better represents the data, is reliable and invariant between men and women. Likewise, IRT findings indicate that CAS is more informative for high levels of COVID-19 anxiety. The CAS in Spanish has adequate psychometric properties to be used as a short measure of COVID-19 anxiety.
本研究旨在使用项目反应理论（IRT）和验证性因素分析（CFA）分析西班牙版的 COVID-19 焦虑量表（CAS）的心理测量特性。参与者为 790 名秘鲁人，通过方便抽样选择，其中大多数为女性。CFA 模型表明，一维结构更好地代表了数据，在男性和女性之间具有可靠性和不变性。同样，IRT 结果表明，CAS 对 COVID-19 焦虑的高水平提供了更具信息量的测量。西班牙语版的 CAS 具有足够的心理测量特性，可以用作 COVID-19 焦虑的简短测量工具。
