| Challenge: | Existing approaches to simulate human clients in mental health counseling are limited and cost prohibitive. |
| Approach: | They propose a framework that supports consistent client simulation for mental health counseling by tracking the mental state of a simulated client, controlling its state transitions, and generating for each state behaviors consistent with the client’s motivation, beliefs, preferred plan to change, and and receptivity. |
| Outcome: | The proposed framework can simulate human clients for mental health counseling tasks and achieve higher consistency than previous methods. |

| Challenge: | Motivational Interviewing (MI) is a client-centered counseling technique designed to address ambivalence and facilitate behavior change in clients. |
| Approach: | They propose to use a STAR framework to evoke change talk by using large language models to assess MI skill competency, client’s state inference accuracy, topic exploration proficiency, and overall counseling success. |
| Outcome: | The proposed agent outperforms several state-of-the-art methods and shows more realistic counselor-like behavior. |
