The present study aimed to evaluate the measurement invariance of the Obsession with COVID-19 Scale (OCS) among seven Latin American countries: Bolivia, Brazil, Cuba, El Salvador, Guatemala, Paraguay, and Uruguay. Although the OCS has been used in several countries and languages, there is a need for approaches that better integrate the cross-cultural equivalence of the scale. A total of 3185 people participated in the study. The results indicated the presence of a unidimensional structure and good reliability indices for the OCS in each country. The alignment method indicated that the OCS is an invariant measure of COVID-19 obsession among the populations of seven Latin American countries. The findings based on IRT analysis indicated that all OCS items had adequate discrimination and difficulty parameters. The findings contribute to the understanding of the internal structure of the scale in different countries at the same time, something that has been pending evaluation.
本研究旨在评估《COVID-19强迫观念量表》（OCS）在七个拉丁美洲国家（玻利维亚、巴西、古巴、萨尔瓦多、危地马拉、巴拉圭和乌拉圭）中的测量不变性。尽管OCS已在多个国家和多种语言中使用，但仍需要能更好整合该量表跨文化等效性的方法。共有3185人参与了这项研究。结果表明，OCS在每个国家都存在单维结构且具有良好的信度指标。比对方法表明，OCS是七个拉丁美洲国家人群中COVID-19强迫观念的不变量度。基于项目反应理论（IRT）分析的结果表明，所有OCS项目都具有足够的区分度和难度参数。这些发现有助于同时理解该量表在不同国家的内部结构，而这一点此前一直有待评估。
