随着社交媒体的兴起，个人在社交平台的疾病自我披露成为了一个备受关注的话题。然而，对于作为特殊公众人物的媒体从业者而言，他们进行疾病自我披露的动机、策略和影响都与其他个体不同。过往的研究主要聚焦于媒体从业者疾病自我披露的动机和影响，而对良性可循环的自我披露内在形成机制缺乏充分研究。本研究通过对中外两位媒体人自我披露抑郁症进行研究，探索了媒体工作者的疾病自我披露形成社会影响力和凝聚力的原因。即对他们在社交媒体平台上自我披露个人患病经历的行为特征、策略和影响进行剖析。媒体工作者在社交平台的影响力得益于与受众建立起良好的传受关系，而自我披露是促进关系发展的关键环节。通过自我披露行为的非线性发展阶段进行分析，本研究发现了媒体工作者在与受众建立“准社会关系”时所遵循的发展规律，及其自我披露行为对公众健康认知和社会风险评估的影响机制。首先，本研究对媒体工作者的疾病自我披露对传受关系建立的作用进行了分析。研究发现，在关系启动阶段，媒体工作者对病情的披露渠道从大众传媒向自媒体的渠道跨越，从“他述”到“自述”进行个人患病经历分享和心理健康知识普及。在自我披露的试验阶段，媒体工作者主要通过引发共情、情感词汇和叙事搭建语境等策略唤起他人的共情，使受众关注心理健康相关议题、调动受众情感，引发他们对心理健康的态度转变。而在自我披露的强化阶段，媒体工作者将个人经历转化为社会责任，通过建构起与受众相对应的社会身份，呼吁共同社会关注心理健康问题，为去除心理疾病的污名化做出努力。其次，通过使用关系发展阶段理论对媒体工作者的疾病自我披露行为进行分析，本文发现了媒体工作者在维持与受众的稳定准社会关系时所遵循的阶段规律。在关系整合阶段，媒体工作者通过栏目设置和符号意义的共识建立了与受众进行意义共享，在媒介互动行为上达成一致性规范；而在关系结合阶段，媒体工作者的社交平台影响力则实现了从线上到线下的转化，通过社群建立和线下活动推动了影响力的多元化和深度化。最后，本研究不仅加深了对社交媒体环境下自我披露行为的理解，也为媒体工作者在健康信息传播和社会风险管理方面提供了重要启示。通过对媒体工作者疾病自我披露的机制进行分析，梳理出良性可持续的自我披露行为的媒介策略。

With the rise of social media, self-disclosure of illnesses on social platforms has become a topic of considerable interest. However, for media practitioners who serve as public figures, their motivations, strategies, and impacts regarding illness disclosure differ from those of other individuals. Previous research has primarily focused on the motivations and impacts of illness disclosure by media practitioners, while there is a lack of sufficient study on the underlying mechanisms of benign and sustainable disclosure. This study examines the disclosure of depression by media practitioners from both domestic and foreign backgrounds to explore the reasons why media workers form social influence and cohesion through illness self-disclosure. Specifically, it analyzes the behavioral characteristics, strategies, and impacts of their disclosure of personal illness experiences on social media platforms.The influence of media workers on social platforms benefits from establishing good relationships with the audience, with self-disclosure being a key factor in fostering relationship development. By analyzing the non-linear developmental stages of self-disclosure behavior, this study identifies the developmental patterns followed by media workers in establishing "Para-social relationships" with the audience and the mechanisms through which their self-disclosure behavior affects public health awareness and social risk assessment.Firstly, this study analyzes the role of illness self-disclosure by media practitioners in establishing the relationship between audience and media practitioner. It finds that during the relationship initiating stage, media practitioners transition their disclosure channels from mass media to self-media, shifting from "other construction" to "self-narrative" to share personal illness experiences and promote mental health knowledge dissemination.During the experimenting stage of self-disclosure, media practitioners primarily use strategies such as eliciting empathy, emotional vocabulary, and narrative construction to evoke empathy in others, drawing attention to mental health-related issues, mobilizing audience emotions, and causing shifts in their attitudes towards mental health. In the intensifying stage of self-disclosure, practitioners transform personal experiences into social responsibility, constructing social identities corresponding to the audience, advocating for collective social attention to mental health issues, and making efforts to destigmatize mental illness.Secondly, by analyzing media practitioners‘ illness self-disclosure behavior using relationship development stage theory, this study identifies the stage patterns followed by practitioners in maintaining stable para-social relationships with the audience. During the relationship integrating stage, media practitioners establish shared meanings with the audience through program settings and symbolic consensus, achieving consistency norms in media interaction behaviors. In the relationship bonding stage, media practitioners‘ social platform influence transitions from online to offline through community building and offline activities, promoting the diversification and deepening of their influence.Finally, this study not only deepens understanding of self-disclosure behaviors in the social media environment but also provides important insights for media practitioners in health information dissemination and social risk management. By analyzing the mechanisms of illness self-disclosure by media practitioners, it delineates media strategies for benign and sustainable self-disclosure behavior. These findings contribute to a deeper understanding of the roles of media practitioners on social media and serve as a guide for public figures interested in health education and public welfare activities. By integrating the theories of relationship development stages and para-social relationships, it also promotes the theoretical construction of mechanisms behind public figures‘ self-disclosure behaviors.
