公共卫生事件中的风险感知和风险传播模型研究——兼论疫情严重程度的调节作用

本文以新型冠状病毒肺炎健康危机为例,运用量化研究的方法,研究公众的风险感知、风险传播行为的特点,以及疫情严重程度对上述二者关系的调节作用。研究发现:(1)风险信息、疫情严重程度主要通过风险感知对公众的风险传播行为起作用,风险感知是该模型中多个因素对传播行为发挥作用的重要中介变量;(2)疫情严重程度对公众的风险感知和传播行为的调节作用部分被证实:疫情严重程度不同地域的公众对风险感知和参与风险传播的行为存在显著差异,且主要存在于疫情较严重和疫情最严重地域的公众之间。

Risk Perception and Risk Communication Model in Public Health Events: Focusing on the Moderation Effects of the Epidemic Severity

This paper uses quantitative methods to analyze the laws of risk perception and communication behaviors, the moderation effects of the epidemic severity between risk perception and communication behaviors during the outbreak of the COVID-19 crisis. It is found that:(1) Risk information and the epidemic severity are playing major roles in risk communication behaviors of the public by risk perception. Risk perception is an important mediation variable that many factors play a role in the communication behaviors in the model.(2) It is partially confirmed that epidemic severity has a moderation effect between the risk perception and communication behaviors. There are significant differences found among different regions. The main differences The main difference are that People perceive greater risk in the fairy severe region than people in the most severe area, and also their communication behaviors are different, with the former more active than the later.
