Heavy alcohol use among young adults is a significant public health problem. Advances in technology may offer an innovative solution. This project will conduct the first controlled test of a feedback intervention for reducing drinking and improving health in young adults by targeting heart rate variability, resting heart rate, and sleep via biosensors and electronic diary methods.


Proposed is a study to conduct the first controlled test of a feedback intervention targeting heart rate variability, resting heart rate, and sleep for heavy-drinking young adults (N=60; ages 18-25) and will leverage the capabilities of a consumer-marketed PPG sensor/mobile app. This study will evaluate the feasibility, acceptability, and preliminary efficacy of this intervention for promoting improvements in drinking, sleep, and health.
