Clinical Summaries of Social Media Timelines for Mental Health Monitoring: Human Versus Large Language Model Comparative Evaluation Study

At this time medium-size LLMs can generate largely accurate and informative clinical summaries of social media timelines, and advanced prompting boosts performance modestly. However, at the time of this writing, they underperform human clinicians in capturing subtle psychological nuances and individual idiosyncrasies. Future work should integrate domain‑specific fine‑tuning and enhanced context modeling to improve LLM clinical fidelity.
