About this trial
The purpose of this study is to test the feasibility and acceptability of an innovative mobile application (uSafeUS+) to reduce college student drinking and sexual assault (SA) risk in real time. Following an initial period of app development, this study will use a pilot 3-arm randomized controlled trial (N = 90; 30/arm) to examine the acceptability, feasibility, and initial evidence of efficacy of the novel, expanded uSafeUS+ app, relative to the existing SA-only focused uSafeUS app (already in use on 24 college campuses), and an assessment-only control condition.
Specifically, the investigators aim to answer the following research questions:
1. Do students like the app (overall and specific features)? 2. How frequently do students use the app within the 1-month exposure period? 3. What barriers and facilitators impact app use? 4. Is there evidence of increased use of protective behaviors on drinking days and over time? 5. Is there evidence of decreased drinking (amount, frequency) or SA risk on drinking days and over time?
Participants will complete:
* A baseline assessment * A 1-month app exposure period with daily surveys about app use on the weekends * Follow-up surveys at 1- and 2-months post-intervention.
