As media technology becomes increasingly participatory, individuals may use social media to share health information and connect with those who have similar health concerns. While prior research has focused on evaluating the feasibility, usability, and effectiveness of traditional health messages, this study investigates the effects of user-generated health content on individuals’ cognitive and emotional responses, as well as their behavioral intentions. An experimental study with a two (story source: personal story vs news story) by two (story ending: happy ending vs sad ending) factorial design was conducted. The results confirmed the positive effects of identification with the narrative character on the experience of being transported, which further led to the behavioral intentions to take countermeasures and viral communication on social media. The sad ending of a narrative was found to elicit emotions that were sufficiently strong to increase perceptions of susceptibility to dengue fever, which, however, failed to result in behavioral intentions.

随着媒体技术越来越具有参与性，人们可能会使用社交媒体共享健康信息并与有类似健康问题的人建立联系。尽管先前的研究集中在评估传统健康信息的可行性，可用性和有效性，但本研究调查了用户生成的健康内容对个人的认知和情感反应以及他们的行为意图的影响。进行了两个（故事结局：个人故事与新闻故事）乘两个（故事结局：幸福结局与悲伤结局）析因设计的实验研究。结果证实了具有叙事特征的身份认同对于被转运的经历具有积极作用，这进一步导致了人们采取行为对策和在社交媒体上进行病毒式传播的意图。
