MACBT Adds Longitudinal Memory to CBT

MACBT’s strongest idea is treating therapy memory as structured clinical state rather than an undifferentiated chat history.

• –Five-agent orchestration maps directly onto CBT workflow stages.
• –CD Memory records distortion type, frequency, severity, and restructuring efficacy across sessions.
• –The Qwen3-14B system improved session quality by 12.6% in the paper’s GPT-4-based evaluation.
• –Its Chinese CBT corpus and DPO alignment prioritize stage fidelity over generic empathetic conversation.
• –Results remain preliminary: evaluation uses simulated patients and GPT-4 judges, covers only three sessions, and still requires stronger crisis safeguards and clinical validation.
