Study Information

Almost a quarter of the population ages 18 years and older reports binge drinking in the last month. Studies show, however, most people believe they can control drinking behavior on their own, yet underestimate how impaired they are when leaving a bar or driving home from a party. Enter the possibility of using smartphone technology as a novel form of self-monitoring alcohol use by leveraging the long-studied connection between alcohol intoxication and changes in walking after drinking.

The app uses technology to measure a person’s motion— for instance, speed and balance— to make estimates of levels of intoxication. The study uses a lab-based alcohol administration protocol and has participants walk when sober and after consuming alcohol. Brief assessments will be conducted during the study visit.


Participants will receive a $70 cash gift card to compensate them for the one-time, approximately four hour study visit.
