【摘要】 目的:在新型冠状病毒肺炎暴发的语境下,厘清用户在社交媒体和电视这两类媒体平台的信息接收、用户有关疫情的个人层面风险感知和社会层面风险感知、戴口罩与"宅在家"两种意向及相应预防行为等变量间的关系。方法:用问卷调查法搜集相关数据,并用结构方程模型对1535份问卷数据进行分析。结果:社交媒体信息接收与两种意向呈正相关,但电视信息接收与两组意向呈负相关;两类媒体的信息接收与两个层面的风险感知均呈正相关;社会层面风险感知与两种意向正相关,且它可以分别中介影响社交媒体信息接收与两种意向间的关系;人际影响、个人健康史、个人旅行史、年龄、性别、收入和教育程度等变量,均可调节社会层面风险感知与两种意向间的关系;两种意向与相应预防行为呈正相关。结论:两类媒介信息接收均能对用户的新冠肺炎预防行为产生积极作用,但背后的心理作用机制复杂;社会层面风险感知是预测新冠肺炎预防行为的重要因素。更多还原

【Abstract】 Objective:To clarify the relationships between users’ preventive behaviors and factors including social media information reception, television information reception, risk perception at personal and societal levels, the intensions of wearing masks and staying at home in the context of COVID-19 pandemic. Methods:Structural equation model was used to analyze the 1535 samples collected from questionnaire survey. Results:Social media information reception is positively correlated with both types of intentions, while television information ships reception is negatively with all of them. Information reception of two types of media can positively affect users’ risk perception at both levels. Risk perception at societal level is positively correlated with the intentions, and it can mediate the relationships between social media information reception and two types of intentions respectively. Factors like interpersonal influence, personal health history, personal travel history, age, gender, income and education can moderate the relationships between social media information reception and both types of intentions. Intentions of wearing masks and staying at homes can effectively predict relative behaviors. Conclusion: Social media and television information reception are salutary for shaping users’ preventive behaviors of COVID-19 while the mechanism behind it is complex, and risk perception at societal level is a significant variable to predict the actual preventive behavior.更多还原
