Leveraging Large Language Models for Simulated Psychotherapy Client Interactions: Development and Usability Study of Client101
Notice bibliographique
Résumé
Background: In recent years, large language models (LLMs) have shown a remarkable ability to generate human-like text. One potential application of this capability is using LLMs to simulate clients in a mental health context. This research presents the development and evaluation of Client101, a web conversational platform featuring LLM-driven chatbots designed to simulate mental health clients. Objective: We aim to develop and test a web-based conversational psychotherapy training tool designed to closely resemble clients with mental health issues. Methods: We used GPT-4 and prompt engineering techniques to develop chatbots that simulate realistic client conversations. Two chatbots were created based on clinical vignette cases: one representing a person with depression and the other, a person with generalized anxiety disorder. A total of 16 mental health professionals were instructed to conduct single sessions with the chatbots using a cognitive behavioral therapy framework; a total of 15 sessions with the anxiety chatbot and 14 with the depression chatbot were completed. After each session, participants completed a 19-question survey assessing the chatbot's ability to simulate the mental health condition and its potential as a training tool. Additionally, we used the LIWC (Linguistic Inquiry and Word Count) tool to analyze the psycholinguistic features of the chatbot conversations related to anxiety and depression. These features were compared to those in a set of webchat psychotherapy sessions with human clients-42 sessions related to anxiety and 47 related to depression-using an independent samples t test. Results: Participants' survey responses were predominantly positive regarding the chatbots' realism and portrayal of mental health conditions. For instance, 93% (14/15) considered that the chatbot provided a coherent and convincing narrative typical of someone with an anxiety condition. The statistical analysis of LIWC psycholinguistic features revealed significant differences between chatbot and human therapy transcripts for 3 of 8 anxiety-related features: negations (t56=4.03, P=.001), family (t56=-8.62, P=.001), and negative emotions (t56=-3.91, P=.002). The remaining 5 features-sadness, personal pronouns, present focus, social, and anger-did not show significant differences. For depression-related features, 4 of 9 showed significant differences: negative emotions (t60=-3.84, P=.003), feeling (t60=-6.40, P<.001), health (t60=-4.13, P=.001), and illness (t60=-5.52, P<.001). The other 5 features-sadness, anxiety, mental, first-person pronouns, and discrepancy-did not show statistically significant differences. Conclusions: This research underscores both the strengths and limitations of using GPT-4-powered chatbots as tools for psychotherapy training. Participant feedback suggests that the chatbots effectively portray mental health conditions and are generally perceived as valuable training aids. However, differences in specific psycholinguistic features suggest targeted areas for enhancement, helping refine Client101's effectiveness as a tool for training mental health professionals.
