Brief Summary

The investigators propose to examine mornings after drinking as an optimal time to provide repeated, personalized feedback, with the goal of reducing hazardous drinking. Specifically, the investigators will further develop and pilot test a novel theory-based personalized feedback intervention (PFI) for heavy drinking young adults. Intervention strategies include personalized feedback (e.g., feedback on prior night blood alcohol concentration, consequences) contrasted with both drinking goals set at baseline and corrective normative feedback (e.g., how last night's drinking compares to peers). Up to 170 participants (50% non-college) will be randomized to one of three groups: PFI with monetary incentives for daily surveys, PFI without monetary incentives, or survey assessment only. The investigators will examine recruitment rates, retention rates, confirmation of intervention content delivery/intake, response rates to daily surveys, data quality, and ratings of intervention value. Investigators will test whether these indicators of engagement differ between those who do and do not receive monetary incentives for daily surveys. Further, baseline, post-test, and 3-month follow-up assessments will allow us to examine differences in drinking behavior between PFI and control. The results of the proposed research will result in a novel and scalable intervention for alcohol misuse among young adults, with potential to have an important impact on the public health problem of high-risk drinking.

Study Arms (3)

Personalized feedback plus incentive

EXPERIMENTAL

Following each daily survey on which a participant indicates prior day drinking, personalized feedback will be provided. Participants in this group will receive $1 per day for submitting their daily survey.

Behavioral: Mobile-delivered personalized feedback

Personalized feedback without incentive

EXPERIMENTAL

Following each daily survey on which a participant indicates prior day drinking, personalized feedback will be provided. Participants in this group will NOT receive $1 per day for submitting their daily survey.

Behavioral: Mobile-delivered personalized feedback

Control

NO INTERVENTION

Participants in this arm will only complete baseline and follow-up surveys.

Interventions

Following each daily survey on which a participant indicates prior day drinking, personalized feedback will be provided on how their most recent behavior (e.g., drinks last night, drinking days so far this week) compare/contrast with personal goals. Participants will then choose whether to receive additional feedback in any of 7 areas: blood alcohol concentrate on, high risk behaviors, consequences of drinking, caloric intake, spending, how drinking compares to peers, and safe drinking strategies. All participants will receive feedback on drinks consumed, and then be asked to choose at least one additional topic for feedback (following each drinking day). In addition to day-level feedback, an aggregate feedback report on drinking patterns and related behaviors will be delivered twice, once at the end of each 2-week period. Once again, they will have the option to view feedback across the range of topics noted above.

Data Sharing

IPD Sharing
Will share

This study will submit and share data with NIAAA Data Archive, a data repository housed within the National Institute of Mental Health Data Archive (NDA). Participants complete a baseline survey of participant characteristics and drinking behavior and related constructs, a post-test survey, and a 3-month follow-up assessment to measure drinking behavior post-intervention. Data from these 3 surveys will be shared.

Time Frame
Data will be shared on or before the NDA submission due dates (April 1 and October 1 each year). It will remain in the archive as per the archive regulations.
