Key Points

  • CARE(Counselor-Aligned Response Engine)は、メンタルヘルス支援におけるカウンセラーの対応に心理的に整合した“リアルタイム返信”を提案するGenAIフレームワークです。
  • ヘブライ語とアラビア語について、専門家カウンセラーが「効果が高い」と評価した危機対応会話データに基づきオープンソースLLMを個別にファインチューニングしています。
  • 会話の全文履歴を学習に用いることで、支援者と相談者の対話が持つ変化する感情的文脈や会話構造を保持することを目指しています。
  • 実験では、非専門のLLMよりもゴールドスタンダードのカウンセラー応答に対して、意味面および戦略面でより高い整合性が示されました。
  • 専門家が検証したデータによるドメイン特化のファインチューニングが、低リソース言語におけるカウンセラー業務の支援とケア品質の向上に有効である可能性を示唆しています。

Abstract

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.
