Inhibitory Control Smartphone App

Status Active, not recruiting

Clinical Trial 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.

Clinical Trial Description

An app giving in-the-moment feedback could increase perceived impairment, and reduce drinking and consequences. The cued go/no-go (CGNG) task is an ideal choice for in-the-moment impairment feedback. Its instructions are simple; practice effects are minimal; and is sensitive to alcohol. The CGNG tests ability to respond fast to "go" targets (activation) while withholding response to "no-go" targets (inhibition). Activation/inhibition tension is externally valid. Dual process models posit risk behaviors stem from overactive appetitive drives that are compelling and hard to inhibit. Poor CGNG performance post-alcohol has been related to poor simulated driving, enhancing external validity. Moderate dosing to .05-.06% blood alcohol content (BAC) reliably increases inhibition errors, but slowing reaction time (RT) to "go" cues requires higher doses. RT to go cues often recovers later in a drinking episode (acute tolerance) but ability to inhibit does not. Thus at this BAC, ability to respond remains but inhibition is impaired, which relates to risk behaviors like DUI as young adults underrate impairment. ;
