Summary

The purpose of this randomized controlled trial is to determine whether pictorial warnings on sugar-sweetened beverages are more effective than neutral labels at reducing parents' purchases of sugar-sweetened beverages for their children. Participants will be parents or guardians of at least one child age 2-12. The trial will take place in a mock convenience store. Participants will be randomly assigned to a pictorial warnings arm in which all sugar-sweetened beverages in the store are labeled with pictorial warnings, or to a control arm in which all sugar-sweetened beverages in the store are labeled with a neutral label. All participants will visit the mock convenience store setup based on their randomized trial arm and be instructed to engage in a shopping task. Participants will complete a computer survey after the shopping task.
