Effects of a brief Mindfulness-Based chatbot intervention (Mindbot) on mindfulness level and stress among cancer patients: a randomized controlled trial
NCT ID NCT07811739
First seen Sep 10, 2026 · Last updated Sep 10, 2026
Summary
This study tests a new digital tool for hospitalized cancer patients. The tool is a chatbot on LINE, a popular messaging app. The chatbot is called Mindbot. Mindbot leads a 10-minute mindfulness practice each day. The practice uses breathing exercises and virtual reality (VR). Adult cancer patients in the hospital ward can join. Participants are randomly placed into one of two groups. One group uses Mindbot every day during their hospital stay. The other group receives usual hospital care through the hospital's existing health app. Researchers measure mindfulness, stress, and heart rate variability (a measure of body stress) before and after each practice. They also collect saliva samples to check a stress hormone called cortisol. Researchers track fatigue and cancer symptoms too. These measurements happen at three time points: hospital admission, hospital discharge, and the first follow-up clinic visit.
