The purpose of this study is to understand social contexts and alcohol use. We hope to learn how being around peers affects alcohol consumption in young adults. About 200 young adults who drink alcohol frequently will take part in the study. This research is being funded by the National Institute on Alcohol Abuse and Alcoholism (NIAAA).
Participation involves one in-person screening session with a same-sex platonic friend. Then participants will complete four in-person laboratory sessions where they will drink beverages containing alcohol or no alcohol. After completion of the laboratory sessions, participants will complete smartphone surveys for 28 days. Lastly, they will complete follow-up surveys 6 months and 12 months post-study enrollment.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Laboratory alcohol administration with longitudinal follow-ups | Experimental | All participants will be in this single arm, which consists on behavioral testing of alcohol administration in the lab, followed by longitudinal follow-ups using Ecological Momentary Assessment and surveys. |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Alcohol (Oral) | Drug | Participants will drink a beverage that will have alcohol or no alcohol. The amount of alcohol consumed will be similar to consuming around 3-4 drinks, with breath alcohol concentration peaking at or around the legal limit for driving (0.08%). |
| Measure | Description | Time Frame |
|---|---|---|
| Drug Effect Questionnaire (DEQ) | The Drug Effects Questionnaire (DEQ), a 5-item visual analog questionnaire (0 to 100 mm; not at all to extremely), will be used to assess the extent to which participants experience the effects of the drug: "feel drug," "feel high," "like drug," "dislike drug," and "want more". | The DEQ will be assessed 30 minutes before alcohol administration, and again 30, 60, 90, 120, 180, and 240 minutes after alcohol administration during each session. |
| Biphasic Alcohol Effects Scale (BAES) | The Biphasic Alcohol Effects Scale (BAES) is a 14-item survey that instructs individuals to rate the extent to which drinking alcohol has produced related subjective effects (0=not at all to 10=extremely). This questionnaire has two subscales consisting of mean scores related to sedation and stimulation. | The BAES will be assessed 30 minutes before alcohol administration, and again 30, 60, 90, 120, 180, and 240 minutes after alcohol administration during each session. |
| Quantity of Alcohol Use during Ecological Momentary Assessment | Quantity of alcohol use will be the number of drinks reported each day during the Ecological Momentary Assessment period. Number of drinks reported will be recoded to create two binary variables alcohol use (alcohol use [1+ drinks], no alcohol [0]) and binge drinking (binge [female: 4+ drinks; male: 5+ drinks], no binge (female: <4 drinks; male<5 drinks]). | Quantity of Alcohol Use will be assessed daily for 28 days. |
| Past 30-day Alcohol Use during Follow-Up | Past 30-day alcohol use (including number of drinks and binge drinking) will be assessed using the timeline follow-back method. | Past 30-day alcohol use will be assessed 6 and 12 months after the initial laboratory sessions. |
| Measure | Description | Time Frame |
|---|---|---|
| Positive and Negative Affect Schedule (PANAS) | The Positive and Negative Affect Schedule (PANAS) is a well-validated brief scale comprised of 20 items meas-uring positive affect (e.g., excited, inspired) and negative affect (e.g., upset, afraid) in the moment. Each item is rated on a five-point Likert Scale, ranging from 1 = Very Slightly or Not at all to 5 = Extremely). | The PANAS will be assessed 30 minutes before alcohol administration, and again 30, 60, 90, 120, 180, and 240 minutes after alcohol administration during each session. |

Per NOT-AA-22-003, this study will submit and share de-identified demographic and primary and secondary outcome data with NIAAA Data Archive (NIAAADA), a data repository housed within the NIMH Data Archive (NDA). Datasets will be findable and identifiable through a persistent study digital object identifier (DOI) generated by NDA.
We will submit data on or before the NDA submission due dates (April 1 and October 1 each year of the award starting in 2025) in accordance with the applicable Data Sharing Terms and Conditions of award. We will perform QA/QC checks on data within 4 months after the submission due dates and address any issues identified by the NDA.
Study data will be available to the research community in perpetuity. Additionally, upon acceptance of a manuscript for publication, we will submit to NIAAADA data used in that publication to allow future analysts to replicate and expand upon the results.
All study data will be deidentified and thus will be made available as public use data to the research community via NIAAADA. Users of the public use data must register with the NIAAADA data archive and agree to the Terms of Use, which are designed to protect study participants by limiting data use to scientific research and aggregate statistical reporting, prohibiting attempts to identify study participants, and requiring immediate reporting of any disclosure of study participant identity.

| Brief Young Adult Alcohol Consequences Questionnaire (YAACQ) during Ecological Momentary Assessment | The validated Brief Young Adult Alcohol Consequences Questionnaire (YAACQ) is a 24-item measure assessing negative alcohol-related consequences. Summary scores are the sum of all items. | The YAACQ will be completed daily for 28 days. |
| Past 30-day Alcohol Consequences during Follow-Up | Past 30-day alcohol consequences will be assessed using the validated Brief Young Adult Alcohol Consequences Questionnaire (YAACQ), a 24-item measure assessing negative alcohol-related consequences. Summary scores are the sum of all items. | Past 30-day alcohol consequences will be assessed at 6 and 12 months following the initial laboratory sessions. |
