EFT-CoT: A Multi-Agent Chain-of-Thought Framework for Emotion-Focused Therapy
This addresses the need for more empathetic and interpretable AI counseling systems for mental health applications, though it is incremental as it builds on existing therapy frameworks.
The paper tackled the problem of existing LLM-based mental health approaches neglecting emotion processing by proposing an Emotion-Focused Therapy-based multi-agent framework, resulting in a model that outperforms baselines and human responses in metrics like empathy depth and structural professionalism.
Leveraging Large Language Models (LLMs) for Mental Health Question Answering (MHQA) is promising for mitigating resource shortages. However, existing Cognitive Behavioral Therapy (CBT)-based approaches predominantly favor a "top-down" rational restructuring, often neglecting clients' embodied experiences and primary emotion processing. To address this, we propose an Emotion-Focused Therapy (EFT)-based Multi-Agent Chain-of-Thought framework (EFT-CoT). Adopting a "bottom-up" trajectory, it deconstructs the intervention into a three-stage reasoning flow: "Embodied Perception - Cognitive Exploration - Narrative Intervention." Utilizing eight specialized agents, the system explicitly executes critical components such as somatic awareness mapping, adaptive assessment, core belief extraction, and narrative restructuring. We further constructed "EFT-Instruct," a high-quality dataset via Chain-of-Thought distillation of approximately 67,000 authentic texts, and fine-tuned a specialized model, EFT-LLM. Experimental evaluations demonstrate that EFT-LLM outperforms strong baselines and human responses across metrics like empathy depth and structural professionalism. Ablation studies confirm the necessity of the multi-agent mechanism. The model exhibits superior psychological reasoning, offering an effective pathway for interpretable, high-empathy counseling systems.
