用真实危机对话数据训练,让AI生成符合心理咨询师风格的实时回复。
CARE: Counselor-Aligned Response Engine for Online Mental-Health Support

- 基于专家评分有效的真实对话数据,微调开源大模型
- 在希伯来语和阿拉伯语中实现与专业咨询师高度一致的回应
- 适合低资源语言的心理健康支持场景,辅助咨询师减轻负担
全球心理健康问题日益严重,情感支持服务压力增大,导致咨询师超负荷工作,关键情境如自杀意念时响应延迟。尽管大语言模型(LLMs)具备强大生成能力,但在低资源语言(如希伯来语、阿拉伯语)的心理健康领域应用仍不充分。现有基于LLM的助手往往难以模仿专业咨询师的共情语言与干预策略,因缺乏大规模真实对话数据训练。为此,我们提出CARE(Counselor-Aligned Response Engine),一个生成式AI框架,通过使用经过专业咨询师评分有效的危机对话子集,分别对开源大模型进行希伯来语和阿拉伯语的微调。模型基于完整对话历史,捕捉情绪演变与互动结构。实验显示,CARE生成的回复在语义与策略上均优于通用大模型,更贴近专业咨询师标准。结果表明,在专家验证数据上进行领域特化微调,可显著提升低资源语言下心理支持的质量与效率。
原文摘要 · Abstract (English)
Mental health challenges are increasing worldwide, straining emotional support services and leading to counselor overload. This can result in delayed responses during critical situations, such as suicidal ideation, where timely intervention is essential. While large language models (LLMs) have shown strong generative capabilities, their application in low-resource languages, especially in sensitive domains like mental health, remains underexplored. Furthermore, existing LLM-based agents often struggle to replicate the supportive language and intervention strategies used by professionals due to a lack of training on large-scale, real-world datasets. To address this, we propose CARE (Counselor-Aligned Response Engine), a GenAI framework that assists counselors by generating real-time, psychologically aligned response recommendations. CARE fine-tunes open-source LLMs separately for Hebrew and Arabic using curated subsets of real-world crisis conversations. The training data consists of sessions rated as highly effective by professional counselors, enabling the models to capture interaction patterns associated with successful de-escalation. By training on complete conversation histories, CARE maintains the evolving emotional context and dynamic structure of counselor-help-seeker dialogue. In experimental settings, CARE demonstrates stronger semantic and strategic alignment with gold-standard counselor responses compared to non-specialized LLMs. These findings suggest that domain-specific fine-tuning on expert-validated data can significantly support counselor workflows and improve care quality in low-resource language contexts.
