Official title
Online Randomized Experiment Evaluating the Perceived Effectiveness of Alcohol Warning Labels
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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.
