First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether a theory-based chatbot could increase colorectal cancer screening rates. 500 adults aged 50-75 in Hong Kong were randomly assigned to receive either standard text reminders or a chatbot that provided personalized risk information and screening guidance. The main goal was to see if more people completed a fecal immunochemical test (FIT) within 3 months.
