Personalized Mobile Phone App Intervention: Challenging Alcohol Expectancies to Reduce High-risk Alcohol Use and Consequences

University of Washington·interventional·Posted Dec 30, 2019·Updated Sep 26, 2024

In Brief

A clinical study evaluating Experimental: Mobile Alcohol Expectancy Intervention for Alcohol; Use, Problem. Completed, enrolled 408 participants across 1 site.

Detailed Summary

The proposed study will develop a smartphone/mobile app intervention that incorporates ecological momentary assessment (i.e., two brief surveys per day) and daily intervention messaging (2 messages per day) for three weeks to target high-risk alcohol use among young adult college students. The intervention mainly focuses on alcohol expectancies, alcohol use, and consequences and the daily associations between these and includes personalized intervention messages based on participants' own event-level expectations and experiences. Other psycho-educational alcohol-related content is also provided over the course of three week intervention. This mobile app intervention will be used in a randomized controlled trial (RCT) comparing young adult college students who receive the intervention with those who only receive assessments via the mobile app.

Interventions

Experimental: Mobile Alcohol Expectancy Interventionbehavioral

Participants randomized to the intervention condition will receive daily intervention messages two times a day for three weeks in the mobile app. The intervention uses participants' own daily responses to personalize messages, when appropriate, that challenges their personal expectations of alcohol's positive effects on mood, social facilitation, and tension reduction, as well as aggression and risk-taking. The intervention messages also focus on intentions to drink and pharmacologically-delayed negative effects. Intervention Messages in general will include feedback based on selected assessment items, weekly summaries generated from the daily assessments, general psycho-educational messages and videos about alcohol, and a toolbox with supplemental information (e.g., personal BAC calculators, resources).
