Study Overview
Brief Summary
The goal of this experiment is to examine responses to alcohol warning messages about 10 different topics among US adult alcohol consumers. The main questions this experiment aims to answer are:
Which warning topics make alcohol consumers in the US want to drink less alcohol? Which warning topics remind alcohol consumers in the US of alcohol's harms? Which warning topics help alcohol consumers in the US learn something new? There will be a total of 20 alcohol messages, 2 messages for each of the 10 topics. For each topic, participants will be randomly assigned to 1 of the 2 messages so that they view a total of 10 alcohol messages. All 10 messages will be shown in random order. Participants will rate each message on how much it makes them want to drink less alcohol, reminds them that drinking can be harmful, and teaches them something new.
Detailed Description
This study aims to determine which topics in alcohol warning labels are most effective at making US adults who consume alcohol want to drink less alcohol, which topics best remind consumers of alcohol's harms, and which topics are most likely to teach consumers something new. The survey research company NORC at the University of Chicago will recruit a sample of 1,000 US adults ages 21+ who consumed alcohol at least one time per week during the past 4 weeks.
Participants will complete a within-subjects online randomized experiment in which they view and rate messages shown on alcohol containers. Participants will rate each message on perceived message effectiveness (primary outcome), reminding of alcohol's harms (secondary outcome), and learning something new (secondary outcome). These tasks will be repeated for 10 messages, each with a different topic. There will be 9 warning topics (i.e., topics about alcohol's harms) and 1 control topic (i.e., neutral topic not about alcohol's harms). In this within-subjects experiment, the survey will present the topics in random order and participants will view 1 of 2 messages for each topic.

Outcomes
Primary Outcomes
Perceived Message Effectiveness
Time Frame: Assessed during one-time 15-minute online study survey
The study will assess perceived message effectiveness using 1 item: "How much does this message make you want to drink less alcohol?" Response options will range from "not at all" (coded as 1) to "a great deal" (coded as 5). Higher scores indicate more perceived message effectiveness. Survey weighted means are reported to account for NORC AmeriSpeak's sampling design to enable results to be statistically representative of the US population of drinkers age \>/=21 who drink alcohol.
Secondary Outcomes
- Reminding of Alcohol's Harms(Assessed during one-time 15-minute online study survey)
- Learning Something New(Assessed during one-time 15-minute online study survey)
