Loneliness threatens public mental wellbeing during COVID-19. In response, YouTube creators participated in the #StayHome #WithMe movement (SHWM) and made myriad videos for people experiencing loneliness or boredom at home. User-shared videos generate parasocial attachment and virtual connectedness. However, there is limited knowledge of how creators contributed videos during disasters to provide social provisions as disaster-relief. Grounded on Weiss's loneliness theory, this work analyzed 1488 SHWM videos to examine video sharing as a pathway to social provisions. Findings suggested that skill and knowledge sharing, entertaining arts, homelife activities, live chatting, and gameplay were the most popular video styles. YouTubers utilized parasocial relationships to form a space for staying away from the disaster. SHWM YouTubers provided friend-like, mentor-like, and family-like provisions through videos in different styles. Family-like provisions led to the highest overall viewer engagement. Based on the findings, design implications for supporting viewers' mental wellbeing in disasters are discussed.

翻译：在COVID-19期间,孤独威胁着公众的心理健康。作为回应,YouTube创建者参加了“与我共聚”运动(SHWM),并为在家中感到孤独或无聊的人制作了无数视频。用户共享的视频产生了超社会情感和虚拟连接。然而,对于创造者如何在灾害期间贡献视频作为救灾提供社会供给的知识有限。根据Weiss的孤独理论,这项工作分析了1488 SHWM视频,以审查视频共享作为社会供给的途径。调查结果表明,技能和知识共享、娱乐艺术、家庭生活活动、现场聊天和游戏游戏是最受欢迎的视频风格。YouTuTube人利用社会关系形成远离灾难的空间。SHWMYouTubeers通过不同风格的视频提供了类似朋友、像导师和类似家庭的条款。类似条款导致最高的总体观众参与。根据调查结果,讨论了支持观众在灾害中心理健康的设计影响。
