The paper examines how Large Language Models (LLMs) can act as simulated clients in online counselling training, comparing their performance to human role-players. Researchers recorded sessions where novice counsellors interacted with both human peers and LLM-generated clients (using Mistral’s Mixtral 8x7b with 4‑bit quantization), then analyzed the interactions at the sentence level using a counselling communication pattern system. Results show both similarities and differences in counselling patterns between the two scenarios, suggesting that LLM-based role‑plays can support competency development while also highlighting areas needing improvement in virtual client simulations.

PsyCLIENT is a framework that uses large language models to simulate counseling clients by conditioning responses on client profiles, dialogue histories, and conversational trajectories that specify target behaviors and content constraints. The authors created PsyCLIENT-CP, a dataset of 120 Chinese client profiles covering 60 counseling topics, and evaluated the system with 24 professional counselors, finding higher authenticity and training utility ratings compared to baseline methods. In a source-identification study, PsyCLIENT-generated dialogues were more often mistaken for real human-client interactions than those from other models, indicating the effectiveness of conversational trajectory modeling in producing realistic counseling conversations.

The paper introduces StratCBT, a new dataset of 9,688 psychological counseling sessions with 256K utterances, each counselor response aligned to one of eight Cognitive Behavioral Therapy (CBT) strategies. It was created by modeling clients’ negative thoughts and generating high‑quality conversations through self‑chat, using realistic sessions for guidance. Experiments show that strategy‑aligned generation improves professional and effective counseling when evaluated with large language model‑simulated clients.
