Generative Artificial Intelligence (AI) is integrated into everyday technology, including news, education, and social media. AI has further pervaded private conversations as conversational partners, auto-completion, and response suggestions. As social media becomes young people's main method of peer support exchange, we need to understand when and how AI can facilitate and assist in such exchanges in a beneficial, safe, and socially appropriate way. We asked 622 young people to complete an online survey and evaluate blinded human- and AI-generated responses to help-seeking messages. We found that participants preferred the AI-generated response to situations about relationships, self-expression, and physical health. However, when addressing a sensitive topic, like suicidal thoughts, young people preferred the human response. We also discuss the role of training in online peer support exchange and its implications for supporting young people's well-being.

翻译：生成式人工智能已融入日常技术，包括新闻、教育和社交媒体领域。作为对话伙伴、自动补全和回复建议功能，人工智能进一步渗透到私人对话中。随着社交媒体成为青少年进行同伴支持交流的主要方式，我们需要了解何时以及如何以有益、安全且符合社会规范的方式促进和协助此类交流。我们邀请622名青少年完成在线调查，评估盲测中人类与人工智能生成的针对求助信息的回复。研究发现，参与者更倾向于选择人工智能生成的与关系、自我表达和身体健康相关的回复。但在涉及自杀念头等敏感话题时，青少年更偏好人类回复。本文还探讨了在线同伴支持交流中训练的作用及其对支持青少年心理健康的启示。免责声明：本文包含自杀意念等敏感话题，请读者自行判断阅读。
