Trial Summary

What is the purpose of this trial?

The goal of this experiment is to examine the effects of 2 types of non-nutritive sweetener (NNS) warning labels among a sample of Chilean parents. The main questions this experiment aims to answer are: Do non-nutritive sweetener warning labels improve consumers' ability to identify when a product contains non-nutritive sweeteners? Do non-nutritive sweetener warning labels impact on consumers' selection of non-nutritive sweetener-sweetened, unsweetened, and/or sugar-sweetened products for their children? Participants will be randomly assigned to 1 of 3 types of labels and view their assigned label on 3 sets of products. Each set will display 4 similar products: one unsweetened, one sweetened with sugar, one sweetened with non-nutritive sweeteners, and one sweetened with both sugar and non-nutritive sweeteners. For each set, participants will identify which product(s) contain NNS and select the product that they would purchase for their child. Researchers will compare results across label types.
