Trial Summary

What is the purpose of this trial?The goal of this experiment is to examine the effects of a warning label signaling that a product is ultraprocessed among a sample of Chilean parents. The main questions this experiment aims to answer are: Do ultraprocessed warning labels on their own impact product purchase intentions? Do ultraprocessed warning labels impact product purchase intentions in the presence of nutrient warning labels? Do ultraprocessed warning labels help more consumers identify ultraprocessed foods? Participants will be randomly assigned to a control arm or an ultraprocessed warning label arm. In both arms, products will carry nutrient warning labels, which are Chile's current policy. Participants will see three similar products, all of which will be ultraprocessed: one not high in any nutrients of concern, one high in sodium, and one high in sodium and saturated fat. For each product, participants will rate their purchase intentions and indicate whether they believe the product to be ultraprocessed. Researchers will compare results across arms.
