Official title: Designing Effective Alcohol Health Warnings: An Experimental Study With Adults in the U.S.
Run by University of Oklahoma · NCT07812545 · Data updated 2026-11-12
A randomized online study will test different warning statements about alcohol and breast cancer risk among adult US women who drink or are young non-drinkers to see which warnings are most convincing.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are US adults aged 18–65 who were assigned female at birth, can read English, and have consumed alcohol in the past 30 days (or are non-drinkers aged 18–29 for the nondrinker group).
✕Probably not a fit
Non-drinking individuals outside the 18–29 age range or individuals outside the US may derive little direct benefit.

What this trial studies
This trial compares multiple alcohol health warning statements delivered on bottles and in ads to determine which formats and messages most effectively influence perceptions, emotional reactions, and intentions related to drinking. It is an online randomized clinical trial enrolling 2,000 US women aged 18–65 who have consumed alcohol in the past 30 days and a subgroup of young non-drinkers aged 18–29. Participants will rate the warnings, allowing researchers to identify messages that could reduce alcohol use and associated breast cancer risk. The study is guided by theories on how warnings affect behavior-mediating factors and actual behavior. Lead sponsor is the University of Oklahoma with participation from Oklahoma City research centers.
Why it matters
Potential benefit: If successful, the findings could inform more effective warnings that help reduce alcohol consumption and breast cancer risk.
How similar studies have gone: Prior research has shown that health warnings can influence perceptions and behaviors, but effectiveness varies by format and audience; this study applies established principles in a new context.
