Guided by the health risk communication literature and the social identity model of deindividualization effects, this study examines whether and how concurrent exposure to health news articles and congruent/incongruent comments posted by anonymous others may affect news viewers' personal risk perception, societal risk perception, and intention to communicate about health risk issues. Two controlled experiments were conducted in Vietnam concerning two controversial health risk issues, including ear picking and child corporal punishment. Results showed a significant interaction effect between comments and perceived similarity on personal risk perception and societal risk perception, such that comments influenced both types of risk perception when viewers perceived that anonymous commenters were ingroup members. Results also indicated the joint effect of comments and perceived similarity on participants' intention to communicate, mediated by their personal risk perception and societal risk perception. Theoretical and practical implications were discussed.
在健康风险沟通文献和去个性化效应的社会认同模型的指导下，本研究考察了同时接触健康新闻文章以及匿名他人发布的一致/不一致评论是否以及如何影响新闻观众的个人风险认知、社会风险认知以及就健康风险问题进行沟通的意愿。在越南针对两个有争议的健康风险问题进行了两项对照实验，包括掏耳朵和儿童体罚。结果显示，评论与感知到的相似性之间在个人风险认知和社会风险认知上存在显著的交互作用，即当观众认为匿名评论者是内群体成员时，评论会影响这两种风险认知。结果还表明，评论与感知到的相似性对参与者沟通意愿有联合效应，通过他们的个人风险认知和社会风险认知起中介作用。讨论了理论和实践意义。
