Voice of the Witness:The Effect of Self-reported Videos of Emerging Infectious Diseases Patients on Public Online Engagement and Emotional Arousal
In contemporary society,the emergence of acute infectious diseases poses a significant threat to human life and health.The dissemination of health information by officials,experts,or professional organizations is crucial for the prevention and control of such diseases.The information released by patients as witnesses and its role should not be ignored,but few studies have explored this.Against the backdrop of the popularity of short videos,this study examines self-reported videos by COVID-19 patients on the Douyin platform.Utilizing the Extended Parallel Process Model(EPPM),content analysis was conducted to explore the content features and their influence on public online engagement and emotional arousal.The findings reveal that all videos contained at least one component of threat(severity and susceptibility)or efficacy(self-efficacy and response efficacy).Both threat and efficacy components positively affected video likes,comments,and favorites.Meanwhile,the high severity component and the high susceptibility component were associated with the arousal of fear and anxiety respectively,while the high self-efficacy component significantly reduced these negative emotional responses.Additionally,the low response efficacy component was found to enhance anxiety arousal.On this basis,we discuss the theoretical significance and practical value of this study.
