Research indicates that parents are crucial in influencing their teens’ drinking habits. A parent handbook was adapted into a phone application for high school students’ parents. The study examined preliminary engagement with the application among a national sample of parents (N=193, Mage=45.26; 116 female). Results indicate 67% of parents accessed the intervention and on average 57% interacted with different components of the application. Findings have implications for adapting online drinking parent-based interventions.
