PeerPen：面向在线心理健康同伴支持的AI辅助写作

中文摘要 AI 辅助

在线心理健康社区依赖同伴支持而蓬勃发展，然而，那些自愿提供帮助的人往往缺乏正式培训，可能难以清晰表达支持性回应。AI协同写作可以降低这一门槛；然而，同伴支持的很大一部分价值源于其被视为个人化的特质，这引发了关于作者身份、所有权和信任的问题。我们构建了PeerPen，一个嵌入在类似Reddit界面中的写作辅助工具，支持两个主要功能：草稿生成和用户撰写回应的修订。通过对15名参与者的半结构化访谈，我们发现PeerPen减轻了撰写回应的负担，并增强了提供支持的信心。参与者希望AI辅助他们的写作，但不接管作者身份，并预期在真实性和信任方面存在紧张关系。这种辅助甚至可能使未使用AI撰写的回应的作者身份变得不确定，从而削弱整个社区的信任。我们提出了AI写作辅助的设计启示，这些辅助应搭建支持性沟通的支架，保留作者身份，并考虑社区层面的信任。

英文摘要

Online mental health communities thrive on peer support, yet those who volunteer to help often lack formal training and may struggle to articulate supportive responses. AI co-writing could lower this barrier; however, peer support derives much of its value from being perceived as personal, raising questions around authorship, ownership, and trust. We built PeerPen, a writing assistance tool embedded within a Reddit-like interface, supporting two main features: draft generation and revision of user-written responses. Through semi-structured interviews with 15 participants, we find that PeerPen reduced the burden of composing responses and increased confidence in offering support. Participants wanted AI to assist their writing without taking over authorship and anticipated tensions around authenticity and trust. Such assistance could make authorship uncertain even for responses written without it, weakening trust across the community. We contribute design implications for AI writing assistance that scaffolds supportive communication, preserves authorship, and accounts for community-level trust.
