Summary

It is important to explore use of technology to reduce drinking. The purpose of this research study is to compare different types of mobile technology for their effects on alcohol drinking and ratings of usability among young adults.This study will be conducted in four phases: a web-based screening assessment; brief appointment on the day of the alcohol drinking session; alcohol drinking session; and a follow-up appointment. Participation in this study will last approximately two months.

Conditions

• Alcohol Use
• Alcohol Drinking
• Drinking Behavior

Interventions

Type	Name	Description
DEVICE	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.
DEVICE	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.
DEVICE	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.
