PsyMix通过多疗法分析提升心理聊天机器人的共情与个性化支持能力
Mixed Chain-of-Psychotherapies for Emotional Support Chatbot
- 采用多疗法分析框架（CoP）解析用户状态，再生成回应
- 在混合疗法微调下表现优于ChatGPT，共情水平接近人类咨询师
- 适合需要高共情与个性化心理支持的应用场景
在心理健康支持聊天机器人领域，展现共情并鼓励自我探索对提供定制化解决方案至关重要。然而，现有方法往往仅提供泛化建议，未能充分理解求助者的情境。为此，我们提出PsyMix，一种在生成回复前，从多种心理疗法视角（即链式心理疗法，Chain-of-Psychotherapies, CoP）分析求助者状态的聊天机器人，并通过在多种CoP混合数据上微调，学习融合不同疗法的优势。综合评估表明，PsyMix在性能上超越ChatGPT基线，且其回应的共情水平与人类咨询师相当。
原文摘要 · Abstract (English)
In the realm of mental health support chatbots, it is vital to show empathy and encourage self-exploration to provide tailored solutions. However, current approaches tend to provide general insights or solutions without fully understanding the help-seeker's situation. Therefore, we propose PsyMix, a chatbot that integrates the analyses of the seeker's state from the perspective of a psychotherapy approach (Chain-of-Psychotherapies, CoP) before generating the response, and learns to incorporate the strength of various psychotherapies by fine-tuning on a mixture of CoPs. Through comprehensive evaluation, we found that PsyMix can outperform the ChatGPT baseline, and demonstrate a comparable level of empathy in its responses to that of human counselors.
