Medical and allied health students are using character-based generative AI chatbots to develop interviewing skills for promoting exercise and healthy behaviors. These AI tools simulate patient interactions, allowing students to practice motivational interviewing techniques in a controlled environment. The approach addresses a key professional competency requirement, as medical programs must train students in communication and behavior change methods. Motivational interviewing has proven effective for encouraging lifestyle modifications in both general and clinical populations. The AI chatbots provide students with repeated practice opportunities to refine their skills in guiding patients toward exercise adoption and maintenance. This training method could standardize skill development across programs while offering personalized feedback. The technology represents a scalable solution for developing crucial patient communication abilities that are essential for promoting physical activity and health behavior change in clinical practice.
