Trial Summary

What is the purpose of this trial?The study evaluates the relative merit of a multi-component PFI presented in the traditional simultaneous delivery (i.e., all components at once) versus a sequential format, wherein individual PFI components are delivered one at a time over several weeks to minimize time and attention demands for each component.

Eligibility Criteria

This study is for individuals who have experienced negative consequences from alcohol use, as measured by specific tests, and engage in heavy drinking episodes. Participants must own a cell phone capable of receiving text messages and be willing to receive them. Those planning international travel soon or unwilling to consent are excluded.

Inclusion Criteria

You have consumed a large amount of alcohol in a short period of time at least once in the past month.
Indicate they own a cell phone with text message capabilities and consent to receiving text messages
At least 2 negative alcohol related consequences on Rutgers Alcohol Problem Index/ Young Adult Alcohol Problems Screening Test in the past month for cohort 2 - 5

Exclusion Criteria

I am willing to participate in the clinical trial.
Failure to provide consent
Plan to travel internationally in the next 12 months (for intervention text purposes)

Participant Groups

The trial is testing two ways of delivering feedback on alcohol use: all at once (traditional) versus over several weeks (sequential). It also examines the effectiveness of follow-up text message boosters in influencing participants' behavior regarding alcohol consumption.
5Treatment groups
Experimental Treatment
Active Control
Group I: Simultaneous Post Feedback Information Delivery +Text MessagesExperimental Treatment2 Interventions
Participants receive all 4 feedback components immediately after providing consent to the Pilot Feasibility Study following the Screening/Baseline Survey. Participants complete a brief 10 minute Post-Feedback Survey and a 3 Week Followup Survey to assess knowledge of the intervention feedback content. Additionally, participants receive the Text Message Booster Component in the days before and during the high risk drinking event celebration(s).
Group II: Simultaneous Post Feedback Information DeliveryExperimental Treatment1 Intervention
Participants receive all 4 feedback components immediately after providing consent to the Pilot Feasibility Study following the Screening/Baseline Survey. Participants complete a brief 10 minute Post-Feedback Survey and a 3 Week Followup Survey to assess knowledge of the intervention feedback content.
Group III: Sequential Post Feedback Information Delivery +Text MessagesExperimental Treatment2 Interventions
Participants receive the first component of their PFI immediately following Baseline and subsequently receive 1 component each week until they receive all 4 components. Participants will complete a Post Feedback Survey and a 3 week follow back and Knowledge assessment. Additionally, participants receive the Text Message Booster Component in the days before and during the high risk drinking event celebration(s).
Group IV: Sequential Post Feedback Information DeliveryExperimental Treatment1 Intervention
Participants receive the first component of their PFI immediately following Baseline and subsequently receive 1 component each week until they receive all 4 components. Participants will complete a Post Feedback Survey and a 3 week follow back and Knowledge assessment.
Group V: Assessment Only ControlActive Control1 Intervention
Participants complete baseline survey, longitudinal follow up assessments, and pre- and post- event surveys.
