In recent times, the healthcare trade has witnessed a major improve in the usage of giant language model-based chatbots, or generative conversational brokers. These AI-powered instruments have been employed for varied functions, together with affected person training, evaluation, and administration. As the recognition of those chatbots grows, researchers from the College of Illinois Urbana-Champaign’s ACTION Lab have taken a more in-depth take a look at their potential to advertise wholesome habits change.
Michelle Bak, a doctoral pupil in info sciences, and Professor Jessie Chin not too long ago printed their findings within the Journal of the American Medical Informatics Affiliation. Their research aimed to find out whether or not giant language fashions might successfully establish customers’ motivational states and supply acceptable info to assist their journey in direction of more healthy habits.
Research Design
To evaluate the capabilities of giant language fashions in selling habits change, Bak and Chin designed a complete research involving three outstanding chatbot fashions: ChatGPT, Google Bard, and Llama 2.

This means that people who’re already within the later levels of habits change, reminiscent of those that have initiated adjustments or have been efficiently sustaining them for a while, can profit from the steering and assist supplied by these AI-powered instruments.
Nonetheless, the researchers additionally found that giant language fashions battle to acknowledge the preliminary levels of motivation, significantly when customers are resistant to vary or ambivalent about making modifications to their habits.
