A Smartphone App to Capture Inhibitory Control as a Novel Moderate Drinking Tool for Young Adults

University of Florida·interventional·Posted Jan 28, 2020·Updated May 30, 2025

In Brief

A clinical study evaluating Control App Version, Standard App Version, and 1 other intervention for Drinking, Alcohol and Drinking Behavior. Completed, enrolled 53 participants across 1 site.

Detailed Summary

The proposed study will address a critical knowledge gap: there are no evidence-based smartphone apps for reducing young adult drinking. The purpose of the study is to test alcohol-related smartphone applications designed to provide assistance during actual drinking situations to help young adults reduce their drinking. It is the researchers hypothesis that participants will self-administer less alcohol when using the experimental app with feedback.

Interventions

Control App Versionbehavioral

The control version is a smartphone-compatible CGNG. The cued go/no-go (CGNG) tests ability to respond fast to "go" targets (activation) while withholding response to "no-go" targets (inhibition).

Standard App Versionbehavioral

The standard version is the same as the control version with the exception that information about performance (correct or incorrect) is displayed along with RT in ms for a correct response during each inter-trial interval.

Experimental, Feedback App Versionbehavioral

The experimental, feedback version includes the standard plus feedback on RT and inhibition errors compared to pre-drinking. The app will state that there are simple alternatives with invitation to press a box to view advice, based on research that risk information may increase risky behavior if convenient options are not given73. Feedback will be worded non-judgmentally per motivational interviewing tenets.
