Individuals with severe mental illnesses (SMI), particularly schizophrenia, experience complex and intense emotions frequently. They increasingly turn to vlogging as an authentic medium for emotional disclosure and online support-seeking. While previous research has primarily focused on text-based disclosure, little is known about how people construct narratives around emotions and emotional experiences through video blogs. Our study analyzed 401 YouTube videos created by schizophrenia vloggers, revealing that vloggers disclosed their fear, sadness, and joy through verbal narration by explicit expressions or storytelling. Visually, they employed various framing styles, including Anonymous, Talk-to-Camera, and In-the-Moment approaches, along with diverse visual narration techniques. Notably, we uncovered a concerning 'visual appeal disparity' in audience engagement, with visually appealing videos receiving significantly more views, likes, and comments. This study discusses the role of video-sharing platforms in emotional expression and offers design implications for fostering online care-seeking for emotionally vulnerable populations.

翻译：患有严重精神疾病（特别是精神分裂症）的个体常经历复杂而强烈的情感波动。他们日益将视频博客（vlog）作为情感表露与在线求助的真实媒介。尽管既有研究主要关注基于文本的情感表露，但关于人们如何通过视频博客构建情感及情感体验叙事的研究尚显不足。本研究分析了401个由精神分裂症视频博主创作的YouTube视频，发现博主通过明确表达或故事讲述的口语叙事方式，表露其恐惧、悲伤与喜悦。在视觉呈现上，他们运用了多样化的镜头风格（包括匿名式、直视镜头式、即时记录式）以及多种视觉叙事技巧。值得注意的是，我们发现了观众参与度中存在令人担忧的“视觉吸引力差异”：视觉吸引力强的视频获得了显著更多的观看量、点赞与评论。本研究探讨了视频分享平台在情感表达中的作用，并为促进情感脆弱群体的在线求助行为提供了设计启示。
