This study aims to describe Facebook users' beliefs toward physical distancing measures implemented during the Coronavirus disease (COVID-19) pandemic using the key constructs of the health belief model. A combination of rule-based filtering and manual classification methods was used to classify user comments on COVID-19 Facebook posts of three public health authorities: Centers for Disease Control and Prevention of the United States, Public Health England, and Ministry of Health, Singapore. A total of 104,304 comments were analyzed for posts published between 1 January, 2020, and 31 March, 2020, along with COVID-19 cases and deaths count data from the three countries. Findings indicate that the perceived benefits of physical distancing measures ( = 3,463; 3.3%) was three times higher than perceived barriers ( = 1,062; 1.0%). Perceived susceptibility to COVID-19 ( = 2,934; 2.8%) was higher compared with perceived severity ( = 2,081; 2.0%). Although susceptibility aspects of physical distancing were discussed more often at the start of the year, mentions on the benefits of intervention emerged stronger toward the end of the analysis period, highlighting the shift in beliefs. The health belief model is useful for understanding Facebook users' beliefs at a basic level, and it provides a scope for further improvement.
本研究旨在使用健康信念模型的关键构念来描述在冠状病毒病（COVID-19）大流行期间使用身体距离措施的 Facebook 用户的信念。使用基于规则的过滤和手动分类方法相结合的方法对美国疾病控制与预防中心，英国公共卫生部和新加坡卫生部的三个公共卫生当局的 COVID-19 Facebook 帖子的用户评论进行分类。分析了 2020 年 1 月 1 日至 2020 年 3 月 31 日发布的帖子以及来自三个国家的 COVID-19 病例和死亡人数数据，共分析了 104,304 条评论。结果表明，身体距离措施的感知益处（= 3,463；3.3％）是感知障碍（= 1,062；1.0％）的三倍。与感知严重程度（= 2,081；2.0％）相比，对 COVID-19 的易感性（= 2,934；2.8％）更高。尽管年初更经常讨论身体距离的易感性方面，但干预措施的益处到分析期结束时更为突出，这突显了信念的转变。健康信念模型可用于在基本水平上理解 Facebook 用户的信念，并为进一步改进提供了空间。
