Brief Summary
The primary objective of the research study is to develop and test a prepartying (aka "pregaming") specific brief mobile app intervention that is intended to help college students reduce their prepartying drinking behavior. Such behavior has been identified as a major contributor to alcohol-related negative consequences among young people. The investigators will first develop the intervention content based on theory and research supporting mechanisms of change in brief interventions with college students and document normative drinking information from 500 college students for inclusion in the intervention content. Investigators will then beta test the intervention with a sample of 14 heavy drinking college students. Focus group feasibility and acceptability feedback will inform the final intervention content. Investigators will then pilot test the mobile-based intervention in a randomized controlled trial of 500 college students who preparty frequently (n = 250 intervention, n = 250 attention control) and determine the efficacy of the intervention on (1) preventing heavy consumption levels during and after prepartying and on (2) reducing students' global levels of heavy drinking and consequences one and three months post-intervention.

21-item Brief Young Adult Alcohol Consequences Questionnaire
Number of 21 assessed alcohol consequences experienced (yes/no). Yes responses are summed to yield a score on this measure. Higher scores indicate experience of a greater number of consequences. Scores range from 0 (no consequences) to 21 (experience of all 21 consequences)

Control
NO INTERVENTIONControl participants receive a personalized attention control task (i.e., listing and ranking favorite movies, music, and books), which controls for the time needed by the intervention group to view the intervention material.
Interventions
The intervention is comprised of a theoretically-informed and empirically-supported, brief, accessible, and personalized intervention to address prepartying drinking. the prepartying intervention app will be tailored toward an individual's personal goals, beliefs (perceptions, expectancies, self-efficacy), and behavior (protective strategies), and focus on the core components of brief interventions that have been cited as constructs that mediate the effects of multiple component intervention programs (e.g., correcting perceived norms, use of protective behavioral strategies, increased self-efficacy, challenging expectancies, feedback on blood alcohol level).
Eligibility Criteria
You may qualify if:
- full time undergraduate college student
- between the ages of 18 and 24
- report typically prepartying at least once per week
