Study Summary
The primary objective of this study is to test the relative effects of climate-impact menu label designs on the healthfulness of consumers' fast-food meal choices. Participants will complete a hypothetical online meal ordering task using a survey which emulates the online menu of a burger restaurant chain. Participants will be randomized for exposure to menus featuring one of five labeling conditions. Secondary objectives include examining total greenhouse gas emissions per meal order and, through a post-order survey, perception of labels between the conditions.
Primary Outcome
The primary outcome measure will be the healthfulness of the fast-food meal selections, measured with a modified Nutrient Profile Index (NPI) score. NPI scores are based on the United Kingdom (UK) Ofcom Nutrient Profiling Model, which is used to score individual foods in the UK to determine which ones can be marketed to children. The NPI is a 0 to 100-point score for foods; scores \>=64 are considered healthy. NPI awards points from nutrients to encourage (e.g., fiber, protein) and nutrients of
