The invariance of the Preventive COVID-19 Infection Behaviors Scale (PCIBS) was evaluated in 12 Latin American countries (Argentina, Bolivia, Chile, Colombia, Cuba, Ecuador, El Salvador, Guatemala, Mexico, Paraguay, Peru, and Uruguay). A total of 5183 people from the aforementioned countries participated, selected using the snowball sampling method. Measurement invariance was assessed by multigroup confirmatory factor analysis (MG-CFA) and Multi-Group Factor Analysis Alignment (CFA-MIAL). In addition, item characteristics were assessed based on Item Response Theory. The results indicate that the original five-item version of the PCIBS is not adequate; whereas a four-item version of the PCIBS (PCIBS-4) showed a good fit in all countries. Thus, using the MG-CFA method, the PCIBS-4 achieved metric invariance, while the CFA-MIAL method indicated that the PCIBS-4 shows metric and scalar invariance. Likewise, the four items present increasing difficulties and high values in the discrimination parameters. The comparison of means of the PCIBS-4 reported irrelevant differences between countries; however, Mexico and Peru presented the highest frequency of preventive behaviors related to COVID-19. It is concluded that the PCIBS-4 is a unidimensional self-report measure which is reliable and invariant across the twelve participating Latin American countries. It is expected that the findings will be of interest to social and health scientists, as well as those professionals directly involved in public health decision making.
在12个拉丁美洲国家（阿根廷、玻利维亚、智利、哥伦比亚、古巴、厄瓜多尔、萨尔瓦多、危地马拉、墨西哥、巴拉圭、秘鲁和乌拉圭）对预防新冠病毒感染行为量表（PCIBS）的不变性进行了评估。共有来自上述国家的5183人参与，采用滚雪球抽样方法进行选取。通过多组验证性因素分析（MG-CFA）和多组因素分析对齐（CFA-MIAL）评估测量不变性。此外，基于项目反应理论评估项目特征。结果表明，PCIBS最初的五项版本并不适用；而PCIBS的四项版本（PCIBS-4）在所有国家都显示出良好的拟合度。因此，使用MG-CFA方法，PCIBS-4实现了度量不变性，而CFA-MIAL方法表明PCIBS-4显示出度量和标量不变性。同样，这四个项目在区分参数方面呈现出递增的难度和高值。PCIBS-4均值的比较显示各国之间差异不显著；然而，墨西哥和秘鲁与新冠病毒相关的预防行为频率最高。得出的结论是，PCIBS-4是一种单维度的自我报告测量方法，在参与研究的12个拉丁美洲国家中可靠且具有不变性。预计这些研究结果将引起社会和健康科学家以及直接参与公共卫生决策的专业人员的兴趣。
