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.

Detailed description

The purpose of this study is to develop and test a smartphone app that can both collect daily data and deliver a personalized intervention using participants' own event-level, real-world experiences to challenge proximal alcohol expectancies and alter the associations between alcohol expectancies and drinking and consequences. The mobile app intervention will be used in a randomized controlled trial comparing young adult college students who receive the intervention with those who only receive assessments via the mobile app. Assessments include an eligibility survey, baseline assessment, and follow-up assessments occurring 1-, 6-, and 12-months post-intervention. The goal of the intervention is to target college students' alcohol expectancies (what they believe or expect alcohol's effects to be) and the associations between alcohol expectancies and alcohol use and related consequences. Intervention content will utilize twice daily messages, one in the morning (AM Messages) and one in the late afternoon or early evening (PM Messages). Most PM Messages draw on information collected in the daily assessments (Personalized Messages). 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 content that supplements information provided in the daily intervention messages.

Interventions

Type	Name	Description
BEHAVIORAL	Experimental: Mobile Alcohol Expectancy Intervention	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).
