This paper introduces a fine-tuned Mistral-7B-instruct model designed as an automated "Supervisor-in-the-Loop" system to address the supervision gap in mental healthcare. By analyzing 106 sessions from the DAIC-WOZ dataset, the framework performs tri-stream analyses for therapeutic alliance tracking, latent risk prediction, and supervisory triage, achieving high accuracy in technique identification and real-time intervention capabilities. The system significantly reduces supervisory triage latency from 72 hours to approximately 10 seconds per session, facilitating timely interventions in high-risk cases.
Real-time risk triage in mental health supervision is now possible, reducing response times from days to seconds.
Modern mental healthcare faces a critical shortage of senior supervisory oversight, leading to a"supervision gap"where novice therapists manage high-stakes risks with delayed professional feedback. This paper proposes a new framework utilizing a fine-tuned Mistral-7B-instruct model as an automated"Supervisor-in-the-Loop"system. By leveraging 106 sessions from the DAIC-WOZ dataset, the model performs a tri-stream analysis: (1) Therapeutic Alliance tracking via semantic adherence, (2) Latent risk prediction using attention-weighted analytics, and (3) Supervisory Triage via a Dynamic Clinical Urgency Index (D-CUI). Our multi-modal VAL (Visual-Acoustic-Linguistic) framework achieves 95% technique identification accuracy [95% CI: 75.1%-99.9%], alliance assessment MAE of 0.105 on a 5-point scale [95% CI: 0.059-0.151], therapeutic fidelity alpha = 0.423, and mean D-CUI of 0.370 [95% CI: 0.322-0.419]. Training converged in 105 steps with 85.2% loss reduction on a single Tesla T4 GPU. The system reduces supervisory triage latency from 72 hours to real time (~10 seconds per session), enabling proactive intervention in high-risk cases. The system addresses the cold-start problem through Bayesian priors and implements timestamp-based modality synchronization for robust multi-modal fusion.
