- Brief 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.
- Detailed Description
This survey will explore the perceptions and understanding of different hypothetical menu label designs related to sustainability and environmental harm compared to a control label The survey research firm CloudResearch will recruit a sample of \~12,400 adults aged 18 years and older who reside in the United States.
Participants will be randomized to view a fast-food online ordering menu with one of seven labeling schemes applied: (1) a QR code on all items (control); (2) Low Sustainability labels; (3) Unsustainable labels; (4) Environmental Harm labels; (5) High Environmental Harm labels; (6) High Environmental Cost labels; and (7) numeric Environmental Cost labels on all items. All fast-food menus will include a selection of main entrée items. The control QR code and numeric environmental cost labels will display labels on all menu items. All other label conditions will apply labels only to items with higher environmental impact as defined by ingredient-level environmental impact estimates based on the Cool Food Pledge Calculator.
Participants will be shown the menu and the label in isolation and will then be asked about interpretations of the label, reactions to the label, perceived message effectiveness (PME) of the label, how helpful the participants find the label to be, and the intention to purchase a menu item with the label. The participants will also be shown two different individual fast-food items with the label to which the participants were randomized (if applicable) in random order and asked about the perceived appeal, healthfulness, and environmental impact of the menu items.
The primary outcome in this exploratory study will be intention to purchase a hypothetical menu item with the label shown. Secondary outcomes include label interpretation, perceived label understandability, perceived label believability, perception that the label grabbed attention, perceived message effectiveness (PME) of the label, perceived helpfulness of the label, perceived level of appeal of menu items, perceived level of healthfulness of menu items, and perceived environmental impact of menu items.

- Primary Outcome Measures
Name Time Method Intention to purchase Immediately after viewing the menu excerpt and label image 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 7-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.
- Secondary Outcome Measures
Name Time Method Label interpretation Immediately after viewing the menu excerpt Label interpretation is assessed with a survey question: "Imagine that you are in a fast-food restaurant (such as Burger King) to order lunch. Next are questions about the label, as displayed on the menu example below. If you saw this label next to an item on the menu, what would you think the label indicates about the item? \[check all that apply\]". Response options provided are a range of statements about the menu item: 1="This menu item is unhealthy", 2="This menu item is healthy" 3="This menu item is good for the environment", 4="This menu item used a lot of natural resources (e.g. land, water) to produce", 5="This menu item will keep you full for a long time", 6="This menu item is bad for the environment", and 7="This menu item will cost consumers more to purchase". Also included are 8="I don't know" and 9="Other" option with open-text entry.
Perceived label understandability Immediately after viewing the menu excerpt and label image After viewing the label, participants will be asked how much the participant agrees or disagrees with the following statement: "This label is easy to understand". Response options are a unipolar 5-point Likert scale: 1=Not at all, 2=A little bit, 3=Somewhat, 4=Quite a bit, 5=A great deal. A higher ranking is better.
Perceived label believability Immediately after viewing the menu excerpt and label image After viewing the label, participants will be asked how much the participant agrees or disagrees with the following statement: "This label is believable to me". Response options are a unipolar 5-point Likert scale: 1=Not at all, 2=A little bit, 3=Somewhat, 4=Quite a bit, 5=A great deal. A higher ranking is better.
Perception that label grabbed attention Immediately after viewing the menu excerpt and label image After viewing the label, participants will be asked how much the participant agrees or disagrees with the following statement: "This label grabs my attention". Response options are a unipolar 5-point Likert scale: 1=Not at all, 2=A little bit, 3=Somewhat, 4=Quite a bit, 5=A great deal. A higher ranking is better.
Perceived message effectiveness (PME) as assessed by the University of North Carolina (UNC)-PME scale Immediately after viewing the menu excerpt and label image Perceived message effectiveness (PME) is measured using the unipolar 3-item University of North Carolina (UNC)-PME scale. Participants will be asked how much each label discourages consumption of or evokes concern of unpleasantness about consumption of foods with the label. After viewing the label, participants will be asked how much the participant agrees or disagrees with the following statements: "This label discourages me from wanting to eat foods with this label", "This label makes foods with this label seem unpleasant", and "This label makes me concerned about the health effects of eating menu items with this label". Response options are a 5-point Likert scale: 1=Not at all, 2=A little bit, 3=Somewhat, 4=Quite a bit, 5=A great deal. A higher ranking is better.
Perceived label helpfulness Immediately after viewing the menu excerpt and label image Perceived label helpfulness is measured with the survey question: "How helpful would you find this label when deciding what to order at a fast-food restaurant?" Response options are a 7-point Likert scale: 1=Very unhelpful, 2=Unhelpful, 3=Somewhat unhelpful, 4=Neither helpful nor unhelpful, 5=Somewhat helpful, 6=Helpful, 7=Very helpful. A higher ranking is better.
