本研究分析了韩国MERS爆发期间具有全国代表性的在线小组调查数据，探讨了社交媒体曝光在塑造公众对MERS风险认知方面的作用。本研究还探讨了社交媒体曝光和风险感知之间的关系的调节作用，系统化处理和自我效能感。这项研究的结果表明，社交媒体曝光与形成风险认知呈正相关。此外，系统化处理和自我效能被发现缓和社会媒体对风险认知的影响。交互效应表明，社交媒体在增加MERS风险认知中的作用是通过系统化处理和自我效能来提高的。本研究的结果和影响进行了更详细的讨论。(C)2017爱思唯尔有限公司版权所有
Analyzing nationally representative online panel survey data during the MERS outbreak in South Korea, this study examined the role of social media exposure in shaping public's risk perceptions of MERS. The present study also investigated the moderating role of heuristic-systematic processing and self-efficacy in the relationship between social media exposure and risk perceptions. The findings of this study showed that social media exposure was positively related to forming risk perceptions. Moreover, heuristic-systematic processing and self-efficacy were found to moderate the impact of social media on risk perceptions. The interaction effects suggested that the role of social media in increasing risk perceptions of MERS was heighted by heuristic-systematic processing and self-efficacy. The results and implications of this study are discussed in greater details. (C) 2017 Elsevier Ltd. All rights reserved.
