Perceptions of and Reactions to Sustainability Menu Label Designs

Summary

The primary objective of this study is to explore perceptions and understanding of different menu label designs related to sustainability and environmental harm. Participants will be randomized to view a fast-food menu featuring one of seven labeling conditions and then will answer questions about the participant's reactions to and interpretations of the label, perceived label effectiveness, intention to purchase a menu item with the label, as well as perceptions of two fast-food menu items.

Interventions

BEHAVIORAL

Control (QR) Labels

Participants will view a fast-food restaurant menu with main entrée items. Each menu item will be displayed with an image of the item, name, price, and total calories. Control (QR) labels will be displayed beneath each item. 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.

BEHAVIORAL

Low Sustainability Labels

Participants will view a fast-food restaurant menu with main entrée items. Each menu item will be displayed with an image of the item, name, price, and total calories. Low Sustainability labels will be displayed beneath select items. 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.

BEHAVIORAL

Unsustainable Labels

Participants will view a fast-food restaurant menu with main entrée items. Each menu item will be displayed with an image of the item, name, price, and total calories. Unsustainable labels will be displayed beneath select items. 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.

BEHAVIORAL

Environmental Harm Labels

Participants will view a fast-food restaurant menu with main entrée items. Each menu item will be displayed with an image of the item, name, price, and total calories. Environmental Harm labels will be displayed beneath select items. 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.

BEHAVIORAL

High Environmental Harm Labels

Participants will view a fast-food restaurant menu with main entrée items. Each menu item will be displayed with an image of the item, name, price, and total calories. High Environmental Harm labels will be displayed beneath select items. 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.

BEHAVIORAL

High Environmental Cost Labels

Participants will view a fast-food restaurant menu with main entrée items. Each menu item will be displayed with an image of the item, name, price, and total calories. High Environmental Cost labels will be displayed beneath select items. 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.

BEHAVIORAL

Numeric Environmental Cost Labels

Participants will view a fast-food restaurant menu with main entrée items. Each menu item will be displayed with an image of the item, name, price, and total calories. Numeric environmental cost labels will be displayed beneath each item. 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.
