A Pilot Feasibility Study Exploring the Preliminary Effectiveness of an AI-Driven Virtual Human Intervention for General Practitioner Obesity Education and Communication-Skills Training

Background: Rising global obesity rates demand effective weight management strategies from general practitioners (GPs). However, time constraints, training gaps, and low confidence often impede GPs' ability to conduct weight-based conversations. This pilot study assessed the feasibility and preliminary effectiveness of an AI-driven Virtual Human (VH) obesity education and communication-skills training tool, specifically designed to address these challenges and enhance obesity education and communication-skills among GPs. Methods: A pilot feasibility study with a pre-post survey design evaluated the impact of the VH tool on knowledge, self-efficacy, empathy toward patients with obesity, and confidence in clinical consultations. Participant perceptions, trust, and intention to use the VH tool were explored. Paired-sample t-tests were conducted to evaluate within-group mean differences. Descriptive statistics were used to evaluate feasibility and acceptability. Results: A total of 22 GPs were recruited. Despite some attrition, significant improvements were observed in knowledge (p = 0.006), self-efficacy (p = 0.001), and combined empathy and confidence scores (p = 0.002). Alongside these improvements, participants demonstrated positive perceptions of the tool, high trust in the VH, and a strong intention to implement the learned strategies. Conclusions: This pilot study demonstrates the potential of an AI-driven VH tool to enhance GP obesity education and communication skills. The observed improvements in key outcomes support the potential of VH technology in medical education on obesity. To further establish the efficacy and explore the broader applicability, future research should focus on larger, controlled trials across various provider groups. Overall, these preliminary observations highlight a promising avenue for enhancing the skills of a wider range of providers in the obesity treatment space.
