Dynamic Presentation

Details and patient eligibility

About

Participants will be asked to select a hypothetical lunch from a menu that features entrees, sides, and drinks. Participants will be able to select a maximum of 1 item from each category. Following this meal selection, participants will complete a short survey about their demographics, their estimates of information about the meal and about recommended eating habits.

Full description

The presence or absence of calorie labels on the hypothetical lunch menu will be randomly assigned to participants. Participants will first be randomly assigned to either the numeric label survey or the light label survey, and then within that survey, participants will be randomly assigned to either a control (no label), an item-level label, or an item-level and meal-level label condition.
