Monitoring compliance with, and understanding the factors affecting, COVID-19 preventive behaviors requires a robust index of the level of subjective likelihood that the individual will engage in key COVID-19 preventive behaviors. In this article, the psychometric properties of the COVID-19 Preventive Behaviors Index (CPBI), including its development and validation in two samples in the United Kingdom, are described. Exploratory and confirmatory factor analyses were performed on data from 470 participants in the United Kingdom who provided demographic information and completed the Fear of COVID-19 Scale, the COVID-19 Own Risk Appraisal Scale (CORAS) and the CPBI. Results showed that a unidimensional, 10-item model fits the data well, with satisfactory fit indices, internal consistency and high item loadings onto the factor. The CPBI correlated positively with both fear and perceived risk of COVID-19, suggesting good concurrent validity. The CPBI is a measure of the likelihood of engaging in preventive activity, rather than one of intention or actual action. It is adaptable enough to be used over time as a monitoring instrument by policy makers and a modeling tool by researchers.
监测对新冠病毒预防行为的依从性并了解影响这些行为的因素，需要一个强有力的指标来衡量个体采取关键新冠病毒预防行为的主观可能性水平。本文描述了新冠病毒预防行为指数（CPBI）的心理测量特性，包括其在英国两个样本中的开发和验证过程。对来自英国的470名参与者的数据进行了探索性和验证性因素分析，这些参与者提供了人口统计学信息，并完成了新冠病毒恐惧量表、新冠病毒自身风险评估量表（CORAS）和CPBI。结果表明，一个包含10个条目的单维模型与数据拟合良好，具有令人满意的拟合指数、内部一致性以及较高的项目负荷。CPBI与对新冠病毒的恐惧和感知风险均呈正相关，表明具有良好的同时效度。CPBI是对参与预防活动可能性的一种衡量，而非意图或实际行动的衡量。它具有足够的适应性，可长期作为政策制定者的监测工具和研究人员的建模工具。
