MyMentorLLM: Multimodal LLM simulation environment for CBT psychotherapy training

Researchers present MyMentorLLM, a multimodal (voice and text) simulation environment for deliberate practice in Cognitive Behavioural Therapy training, generating 2,100 complete CBT sessions linking simulated DSM-5-TR-grounded patients, trainee therapists, and expert supervisors. Simulated patients expressed disorder-congruent emotional profiles and trainees mirrored these as in real counselling, while supervisor quality varied across LLMs with most overestimating trainee competence. Native speech-to-speech models scored closest to human supervisors, and symptom identification accuracy scaled with model size. The work demonstrates feasibility of LLM-based deliberate practice simulation for clinical training while flagging calibration and harmful feedback as open risks.
