Summary

Exploring technology based tools to reduce drinking is important. The purpose of this research study is to compare different BAC monitoring apps for their effects on alcohol drinking and ratings of usability among young adults.This study will be conducted in six phases: a web-based and in-person screening assessment; brief counseling session on the day before the alcohol drinking session; brief appointment on the day of the alcohol drinking session; alcohol drinking session; two-week field period; and a follow-up appointment. Participation in this study will last approximately two months.

Interventions

Type	Name	Description
OTHER	Smartphone breathalyzer device/app use	Participants randomized to this condition will be able to blow into the smartphone breathalyzer after consuming each alcoholic drink, which produces an accurate breath alcohol reading on the app. These breath alcohol readings may inform participants' subsequent decisions regarding drinking.
OTHER	BAC estimator app use	Participants randomized to this condition will be able to make an entry into the BAC estimator app after consuming each alcoholic drink, which produces an estimated blood alcohol concentration based on the individual's sex, weight, number of alcoholic drinks and time spent drinking alcohol. These estimated blood alcohol concentrations may inform participants' subsequent decisions regarding drinking.
OTHER	Text messaging procedure	Participants randomized to this condition will be instructed to send a text to a smartphone they will use for the study after each alcoholic drink. A consideration of the number of texts sent may inform participants' subsequent decisions regarding drinking.
