While there has been increasing attention to the role of social media during infectious disease outbreaks, relatively little is known about the underlying mechanisms by which social media use affects risk perception and preventive behaviors during such outbreaks. Using data collected during the 2015 Middle East Respiratory Syndrome coronavirus (MERS-CoV) outbreak in South Korea, this study explores the relationships among social media use, risk perception, and preventive behaviors by examining the mediating role of two self-relevant emotions: fear and anger. The findings demonstrate that social media use is positively related to both of these emotions, which are also positively related to the public's risk perception. The findings also indicate that social media use can significantly increase preventive behaviors via the two self-relevant emotions and the public's risk perception.
尽管人们越来越关注社交媒体在传染病爆发期间的作用，但对于社交媒体使用如何影响此类爆发期间的风险感知和预防行为的潜在机制，了解相对较少。本研究利用韩国 2015 年中东呼吸综合征冠状病毒（MERS-CoV）爆发期间收集的数据，通过检验两种自我相关情绪（恐惧和愤怒）的中介作用，探讨了社交媒体使用、风险感知和预防行为之间的关系。研究结果表明，社交媒体使用与这两种情绪呈正相关，而这两种情绪也与公众的风险感知呈正相关。研究结果还表明，社交媒体使用可以通过两种自我相关情绪和公众的风险感知显著增加预防行为。
