Lately, the healthcare trade has witnessed a big enhance 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 schooling, evaluation, and administration. As the recognition of those chatbots grows, researchers from the College of Illinois Urbana-Champaign’s ACTION Lab have taken a better take a look at their potential to advertise wholesome conduct change.
Michelle Bak, a doctoral pupil in info sciences, and Professor Jessie Chin just lately revealed their findings within the Journal of the American Medical Informatics Affiliation. Their examine aimed to find out whether or not giant language fashions may successfully establish customers’ motivational states and supply acceptable info to assist their journey in direction of more healthy habits.
Examine Design
To evaluate the capabilities of giant language fashions in selling conduct change, Bak and Chin designed a complete examine involving three distinguished chatbot fashions: ChatGPT, Google Bard, and Llama 2.

The eventualities have been fastidiously crafted to symbolize the 5 distinct motivational phases of conduct change:

This implies that people who’re already within the later phases of conduct change, reminiscent of those that have initiated modifications or have been efficiently sustaining them for a while, can profit from the steering and assist supplied by these AI-powered instruments.
Nevertheless, the researchers additionally found that enormous language fashions wrestle to acknowledge the preliminary phases of motivation, notably when customers are resistant to vary or ambivalent about making modifications to their conduct.
