June 4, 2025 – This new approach uses a tool called microinteraction-based ecological momentary assessment, or μEMA for short. It works on smartwatches and collects small pieces of data throughout the day. This method reduces the pressure on users while increasing accuracy and reliability. AlcoWatch, marks the first time μEMA has been used over a long period to collect alcohol-related data.
Researchers tested this new method on 32 people. They were part of a long-term health study and lived in the Bristol area. For 12 weeks, these participants wore basic Android smartwatches equipped with the custom-built AlcoWatch app.
Five times a day, the watch asked them short questions. The questions focused on any alcohol they had consumed in the last two hours, where they drank it, and whether they were alone or with others. The aim was to collect real-time data in natural settings, with minimal disruption to daily life.
