Personalized Feedback After Alcohol Health Education for Members of Greek Life (GREEK Study)

Study Overview
=================
Brief Summary
-----------------
Heavy episodic alcohol use within the college student population is widespread, creating problems for student drinkers, their peers, and their institutions. Negative consequences from heavy alcohol use can be mild (e.g., hangovers, missed classes), to severe (e.g., assault, even death). Although online interventions targeting college student drinking reduce alcohol consumption and associated problems, they are not as effective as in-person interventions. Online interventions are cost-effective, offer privacy, reduce stigma, and may reach individuals who would otherwise not receive treatment. In a recently completed randomized, controlled trial, an emailed booster with personalized feedback improved the efficacy of a popular online intervention. A second randomized, controlled trial confirmed efficacy for students of legal drinking age for a longer timeline. Although promising, the booster incorporated in the study needs further empirical refinement. The current project seeks to build on past progress by further developing and refining the booster. In particular, the current project is an extension of previous work by expanding the investigation into complete social networks (students involved in Greek life). This booster contains feedback about alcohol use tailored to the recipient, and will be emailed 2, 6, 10, and 14 weeks after baseline (experimental condition), or not at all (control condition). This study will be conducted specifically with students who are members of fraternities or sororities at ODU (specifically, those in the organizations that agree to participate). This population engages in heavy alcohol use so is ideal for an alcohol intervention. Members of fraternities and sororities (i.e., Greek life) engage in more frequent drinking, consume more when drinking, and have higher peak drinking occasions than students not involved in Greek life. We aim to administer the intervention and associated booster among complete networks of Greek organizations to examine how the intervention and booster and progress through social networks.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Placebo Comparator: Intervention-only Control<br>Participants navigate through e-checkup to go, the well-established alcohol intervention. Any follow-up emails sent to them later contain only a reminder to participate in follow-up surveys. | Behavioral: e-checkup to go<br>* The e-checkup to go alcohol program is designed to motivate individuals to reduce their alcohol consumption using personalized information about their own use and risk factors. The program is a combination of several components including alcohol education, personalized feedback, attitude-focused strategies, and skills training. It is self-guided and requires no face-to-face time with an administrator. It provides tailored feedback regarding quantity and frequency of alcohol use, normative comparisons, physical health information, amount and percent of income spent on alcohol, negative consequences feedback, explanation and advice for how to reach their goals, and resources.<br>|
| Experimental: Intervention plus delayed feedback booster<br>Participants navigate through e-checkup to go, the well-established alcohol intervention, then receive a series of feedback booster emails. It contains a reminder to participate in follow-up surveys, plus personalized feedback based on participant-reported perceived alcohol norms, actual alcohol norms, their own use, and harm reduction strategies. | Behavioral: e-checkup to go<br>* The e-checkup to go alcohol program is designed to motivate individuals to reduce their alcohol consumption using personalized information about their own use and risk factors. The program is a combination of several components including alcohol education, personalized feedback, attitude-focused strategies, and skills training. It is self-guided and requires no face-to-face time with an administrator. It provides tailored feedback regarding quantity and frequency of alcohol use, normative comparisons, physical health information, amount and percent of income spent on alcohol, negative consequences feedback, explanation and advice for how to reach their goals, and resources.<br>Behavioral: Delayed feedback booster<br>* Booster emails will contain normative feedback indicating average consumption for students at the same institution by sex, their perceptions of student drinkers at the same institution, their own reported consumption, and reminders of strategies they can use to protect themselves from alcohol-related harm.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Alcohol consumption | Participant self-reported number of standard drinks consumed by participant over a typical week for the past 30 days. | past 30 days | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Alcohol-Related Consequences | Participant self-report on the Brief-Young Adult Alcohol Consequences Questionnaire (B-YAACQ; Kahler et al., 2005), which assesses alcohol-related problems experienced by the participant. Total scores are created by summing all individual items, and range from 0 to 24, with higher values representing more problems experienced (i.e., worse outcomes). | past 30 days |
