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.

Noticing, recall, and understanding of the added sugar menu label
Noticing, recall, and understanding (hereafter, "noticing") of an added-sugars nutrient label where participants will be asked if they noticed any menu labels. If "Yes", participants would be asked what the warning label told them about (e.g., added sugars), and if answered "added sugars", what about added sugars (e.g., high amount of added sugars). If the three answers were "Yes", "Added sugars", and "high amount of added sugars", the dichotomous variable would be correct. Otherwise, the variable would be classified as incorrect. This outcome will be compared between the experimental PSA arm and the control PSA arm and between each of the three PSA intervention themes. Analysis will use Poisson regression with robust standard errors. Adapted from doi: 10.1016/j.amepre.2025.108038.
Within approximately 5 minutes of intervention exposure
Grams of added sugar ordered
After the intervention, participants will place hypothetical meal orders from 2 realistic menus, shown in random order, that display an added-sugars warning label next to items containing ≥100% of the Daily Value for added sugars and a disclosure statement explaining the label's meaning. Added-sugars data will be estimated using restaurant website nutritional information. Analyses will use linear regression. Adapted from doi: 10.1016/j.amepre.2025.108038.

Viewing safe driving PSAs from a hypothetical state public health department.
Viewing added-sugars PSAs from a hypothetical state public health department. (Participants in this arm will be randomly assigned to view only one of the three interventions.)
Viewing 2 PSAs with a "labels are coming soon" theme that contain an added-sugars warning label and a statement stating that chain restaurant menus must place warning labels on items that contain or exceed the recommended daily limit of added sugars.
