监测COVID-19预防行为的遵守情况并了解影响COVID-19预防行为的因素，需要一个强有力的指标，衡量个人将从事关键COVID-19预防行为的主观可能性水平。在这篇文章中，COVID-19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。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COVID-19恐惧量表、COVID-19自身风险评估量表（CORAS）和CPBI。结果表明，一个一维的，10个项目的模型拟合数据很好，具有令人满意的拟合指数，内部一致性和高项目负荷的因素。CPBI与COVID-19的恐惧和感知风险呈正相关，表明具有良好的同时效度。CPBI是对从事预防活动的可能性的衡量，而不是意图或实际行动。它具有足够的适应性，随着时间的推移，可以作为决策者的监测工具和研究人员的建模工具。
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.
