Added-Sugars Warning Label PSAs

Summary

The purpose of this study is to determine if exposure to language-matched English-Spanish public service announcements (PSAs) can increase the understanding of and response to added-sugars menu warning labels among U.S. Hispanic adults. The hypothesis is that the experimental PSAs educating consumers about a new added-sugars menu label will significantly improve understanding of the label and reduce grams of added sugars in meals ordered from menus displaying the label. Participants will be recruited and randomized to one of two arms: (1) Control Arm: Viewing PSAs stating that using a phone while driving is dangerous or (2) Intervention Arm: Viewing PSAs informing participants about new added-sugars menu labels. Within the intervention arm, participants will be randomized to view one of three PSA themes.
