NCT07214805

Brief Summary

The primary objective of this study is to explore perceptions and understanding of different menu label designs related to ultra-processed foods (UPF). Participants will be randomized to view a fast-food online menu excerpt featuring one of sixteen labeling conditions and then will answer questions about the participant's reactions to and interpretations of the label, perceived label effectiveness, the intention to purchase a menu item with the label, as well as the participant's perceptions of fast-food menu items with and without the label.

Outcome Measures

Primary Outcomes (1)

  • Intention to purchase

    Intention to purchase is measured with the survey question: "How likely would you be to purchase a menu item with this label?" Response options are a 5-point Likert scale: 1=Very unlikely, 2=Unlikely, 3=Somewhat unlikely, 4=Neither likely nor unlikely, 5=Somewhat likely, 6=Likely, 7=Very likely. A higher rating is better.

    Immediately after viewing the menu excerpt and label image

Secondary Outcomes (6)

  • Label interpretation

    Immediately after viewing the menu excerpt and label

  • Perceived label understandability

    Immediately after viewing the menu excerpt and label image

  • Perceived label believability

    Immediately after viewing the menu excerpt and label image

  • Perception that label grabbed attention

    Immediately after viewing the menu excerpt and label image

  • Perceived message effectiveness (PME) as assessed by the University of North Carolina (UNC)-PME scale

    Immediately after viewing the menu excerpt and label image

  • +1 more secondary outcomes

Other Outcomes (2)

  • Perceived level of appeal of labeled food item

    Immediately after viewing each menu item

  • Perceived level of healthfulness of labeled food item

    Immediately after viewing each menu item

Interventions

Participants will view a fast-food restaurant menu excerpt. Each menu item will be displayed with an image of the item, name, price, and total calories. The Ultra-Processed, Red, Icon-plus-text labels will be displayed next to items that are ultra-processed. Participants will view the menu and then the label in isolation and then be asked about a hypothetical intention to purchase a menu item with the label.

Model Details: Participants will be randomized to view a fast-food online ordering menu with one of sixteen labeling schemes, varying by message ("Ultra-Processed" vs. "Contains Food Additives" vs. "Warning: Ultra-Processed" vs. "Warning: UPF"), background and text color (red with white text vs. yellow with black text), and type (icon-plus-text vs. text-only). Participants will be asked about a hypothetical intention to purchase a menu item with the label to which the participants were randomized.
