New framework PatientAct enhances realism in AI mental health client simulations

Researchers have developed PatientAct, a novel framework designed to create more realistic simulated clients for mental health training and evaluation. Unlike existing simulators that produce overly cooperative clients, PatientAct integrates established clinical theories, such as the 5Ps case formulation, to provide causal depth and dynamic memory layers. This approach allows simulated clients to exhibit resistance based on trust thresholds and therapeutic alliance, leading to more plausible and diverse interactions. Evaluations show PatientAct significantly outperforms baseline simulators in generating clinically realistic profiles with improved resistance quality and behavioral realism. AI

IMPACT Enhances the realism of AI-driven training tools for mental health professionals, potentially improving counselor training and AI therapist evaluation.

    PatientAct: Theory-Grounded Mental Health Client Simulation

    arXiv:2608.12750v1 Announce Type: cross Abstract: LLM-based simulated clients are increasingly used to train novice counselors, evaluate LLM therapists, and generate synthetic data. However, current simulators produce overly cooperative clients that disclose too readily, accept t…
