AI Chatbots Support Health Behavior Change
University of Utah authors conducted a PRISMA-ScR scoping review through March 2024, analyzing 43 studies of text-based AI chatbots across eight health behaviors. They found chatbots mainly acted as routine coaches (63%) or on-demand assistants (28%), relied on CBT frameworks and non-code platforms like Dialogflow, and produced 81.7% positive comparisons though only 35.8% showed moderate-or-larger effects. The review calls for more research on cost, implementation, and understudied behaviors.

Comprehensive peer-reviewed synthesis delivers practical guidance; however, moderate novelty and exploratory, mixed-effect evidence limit transformative impact.
