Alcohol & Mobile Phone Study to Reduce High-risk Alcohol Use and Consequences (AMPS)
Personalized Mobile Phone App Intervention: Challenging Alcohol Expectancies to Reduce High-risk Alcohol Use and Consequences

Intervention / Treatment
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 (mAEC) 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.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Mobile Alcohol Expectancy Challenge (mAEC)
Participants randomized to the mAEC condition will receive twice daily intervention messages for three weeks and have access to other psycho-educational alcohol information.
|
Participants randomized to the mAEC 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).
|
No Intervention: Assessment-only Control
Participants randomized to the control group will not receive any intervention.
They will be an assessment-only control group.
