Researchers have developed PSI-Bench, a new evaluation framework for assessing depression patient simulators used in mental health training. This framework offers clinically grounded and interpretable diagnostics across various simulation dimensions. Benchmarking seven large language models revealed that current simulators often produce overly long responses, exhibit reduced behavioral variability, and follow a predictable emotional trajectory. The study also indicated that the simulation framework itself has a greater impact on fidelity than the scale of the underlying language model. AI
