| Challenge: | Claude Sonnet 3.5 consistently outperforms all models, but smaller models often approach human-rated empathy levels. |
| Approach: | They introduce a dataset comprising 10,000 two-turn conversations across 500 diverse, clinically-grounded PTSD personas. |
| Outcome: | The proposed model outperforms all models but has a "knowledge transfer ceiling" older adults prefer validation responses while graduate-educated users prefer emotionally layered responses . |

| Challenge: | Synthetic data adoption in healthcare is driven by privacy concerns, data access limitations, and high annotation costs. |
| Approach: | They compare real and synthetic PTSD therapy conversations using linguistic, structural, and protocol-specific metrics like turn-taking and treatment fidelity. |
| Outcome: | The proposed framework assesses clinical fidelity beyond surface fluency. |
