Young Adult Naturalistic Alcohol Study (YANAS) Using Smartphone Technology in a Simulated Laboratory Environment

Terminated

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

• Registration Number: NCT02841735
• Lead Sponsor: University of Florida

Brief 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.

Arm && Interventions

Group	Intervention	Description
Smartphone breathalyzer device & app	Smartphone breathalyzer device/app use	This is a small device that attaches 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 a simulated laboratory.
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 a simulated laboratory.
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 a simulated laboratory.

Primary Outcome Measures
