About

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.

Enrollment: 9 patients

Sex: All

Ages: 21 to 25 years old

Volunteers: Accepts Healthy Volunteers

Trial design

9 participants in 3 patient groups

Smartphone breathalyzer device & app

Description:

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.

Treatment:

Device: Smartphone breathalyzer device/app use

BAC estimator app

Description:

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.

Treatment:

Device: BAC estimator app use

Text Messaging

Description:

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.

Treatment:

Device: Text messaging procedure
