本研究提出AI伴侣中断风险评估框架，基于30起事件和Reddit数据定量分析，发现中断导致用户焦虑、压力等心理反应即时上升。
AI 中文摘要
AI伴侣能够提供有意义的人际关系，然而这些关系仍易受平台发起的变化影响。我们研究AI伴侣中断现象，即平台改变或终止用户与AI持续陪伴关系的变化。我们整理了主要平台上发生的30起中断事件，开发了包含六种中断类型的分类体系，识别出三大类中断原因，并提出了一个包含四个维度的风险评估框架：关系连续性中断、人群脆弱性、沟通缺失和过渡支持缺失。利用纵向Reddit数据，我们采用结合预测对照的分层贝叶斯中断时间序列模型，估计社区层面的社会心理反应。跨事件分析显示，中断发生与焦虑、压力、自杀倾向表达和悲伤激活的即时增加相关，其中关系连续性中断和过渡支持缺失与多个结果维度上更不利的即时反应相关。我们的研究提供了AI伴侣中断的跨平台特征描述、其社会心理影响的定量证据，以及一个在实施前评估其潜在风险的前瞻性框架。
英文摘要
AI companions can provide meaningful relationships, yet these relationships remain vulnerable to platform-initiated changes. We study AI companion disruptions: platform changes that alter or terminate users' ongoing companionship with an AI. We compile 30 disruption events across major platforms, develop a taxonomy of six disruption types, identify three broad reasons for disruption, and propose a risk-assessment framework comprising four dimensions: relational discontinuity, population vulnerability, communication deficit, and transition-support deficit. Using longitudinal Reddit data, we estimate community-level psychosocial responses with a hierarchical Bayesian interrupted time-series model incorporating predictive controls. Across events, disruption onset was associated with immediate increases in anxiety, stress, suicidal expression, and grief activation, with relational discontinuity and transition-support deficit being associated with more adverse immediate responses across several outcomes. Our findings provide a cross-platform characterization of AI companion disruptions, quantitative evidence of their psychosocial impacts, and a prospective framework for assessing their potential risks before implementation.
