Smartphone Technology: Young Adult Drinking

Phase 1

Completed

• Conditions: Drinking Behavior; Alcohol Drinking; Alcohol Use
• Interventions: Other: Smartphone breathalyzer device/app use; Other: BAC estimator app use; Other: Text messaging procedure

• Registration Number: NCT02963818
• Lead Sponsor: University of Florida

Brief 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.

Arm && Interventions

Group	Intervention	Description
Smartphone breathalyzer device & app	Smartphone breathalyzer device/app use	This is a small device that connects to a smartphone with an accompanying app that produces accurate breath alcohol readings when a user blows into a small tube attached to the device. Participants randomized to this study condition will have the opportunity to use this device and app during an alcohol drinking session in an actual bar and during a two-week field period.
BAC estimator app	BAC estimator app use	This is an app that produces estimated blood alcohol content (eBAC) readings based on sex, weight, number of drinks and time taken to consume drinks. Participants randomized to this study condition will have the opportunity to use this app during an alcohol drinking session in an actual bar and during a two-week field period.
Text Messaging	Text messaging procedure	A procedure whereby one sends a text message to the phone one is using after each alcoholic drink. Participants randomized to this study condition will have the opportunity to the text messaging procedure during an alcohol drinking session in an actual bar and during a two-week field period.
