[目的/意义]公众线上健康信息搜寻增多，其中短视频平台已成为重要的健康信息媒介，而短视频平台传 播的健康信息中不乏虚假信息，且部分虚假健康信息会被用户采纳。为此，分析用户短视频虚假健康信息采纳行 为的动因，有利于短视频平台虚假健康信息治理，优化网络健康信息生态。[方法/过程]采用问卷调查法，收集了 375位短视频用户的有效数据，结合应对理论对一次评估中的机会评估（感知情感支持、感知信息支持）、威胁评估 （感知风险、感知障碍），以及二次评估（健康信息素养）进行短视频平台内的情景化，以厘清短视频用户虚假健康 信息采纳的动因。[结果/结论]对于一次评估，在机会评估中，短视频用户的感知信息优势显著正向影响其虚假健 康信息采纳行为，而在威胁评估中，短视频用户的感知风险显著负面影响其虚假健康信息采纳行为；对于二次评 估，短视频用户的健康信息素养显著负面影响其虚假健康信息采纳行为。本文拓展了在线社区健康信息研究的 视角，延伸了应对理论的研究情境，明晰了短视频用户虚假健康信息采纳的动因。

[Purpose/significance] The public online health information search is increasing, and short video platforms have become an important health information medium. There exists a large amount of false health information on the short video platforms, which may be adopted by users. Therefore, analyzing driving factors of false health information adoption of short video users is conducive to the governance of false health information on the short video platforms and the optimization of online health information ecology.[Method/process] To clarify the driving factors of false health in⁃ formation adoption behavior of short video users, this study has contextualized opportunity appraisals (perceived emo⁃ tional support and perceived information superiority), threat appraisals (perceived risk and perceived barriers) and sec⁃ ondary appraisals (health information literacy) under the short video platform context based on coping theory. [Result/ conclusion] For primary appraisal, in opportunity appraisal, short video users' perceived information superiority exerts positive significant effect on their false health information adoption, while in threat appraisal, short video users' per⁃ ceived risk exerts negative significant effect on their false health information adoption. For secondary appraisal, the health information literacy of short video users negatively and significantly affects their false health information adop⁃ tion.This study has enriched the online community health information research, extended the research context of coping theory, and clarified the driving factors of false health information adoption of short video users.
