Impact of Environmental Nudges on Dietary Quality

Participants will be recruited from CloudResearch Prime Panels (an online panel research company). Study participants include 2,000 young adults between 18 and 25 years old with at least 25% currently enrolled in college, recruited to match census distribution of race/ethnicity and gender. Participants will electronically acknowledge their consent to participate in the study. On the study platform (Qualtrics), participants will be randomly assigned to 1 of 2 arms with equal probability. Participants will complete a shopping task via an online 9-minute survey. They will view products displayed as if they were offered from a grocery store. Products will be frozen meals, such as burritos and pizza, snack items such as dried fruit and chips, and protein items, such as ground beef and chicken breasts. They will then be instructed to select 1 item they most wish to purchase from each category. Participants in the experimental arm will shop and receive environmental nudges in the form of labels, feedback, peer comparisons, and suggested product swaps. In the control arm, participants will conduct online shopping tasks without any environmental nudges. After selecting products, participants will answer questions about the products and labels, as well as standard socio-demographic questions.
