简要总结
Purpose: The overall purpose of this study is to evaluate the impact of a suite of environmentally focused nudges on the nutritional quality of consumers' food selections.
Participants: ~2,000 US adults ages 18-25, at least 25% currently enrolled full-time in college, recruited from CloudResearch Prime Panels.
Procedures: Participants will be randomly assigned to view food products with or without environmental nudges (eco-labels, peer comparison message, and swaps). They will be asked to select items that they most wish to purchase and will then be asked a series of questions about the products and nudges. Questions will also include standard socio-demographic variables.
详细描述
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.

结局指标
主要结局
Nutri-Score Scores
时间窗: Immediately after exposure to intervention and product selection task, assessed during 1-time online study visit
Healthfulness of product selections (operationalized as products' Nutri-Score scores). Products' Nutri-Score scores are calculated using the updated 2022 algorithm released by the Scientific Committee of the Nutri-Score (ScC). Scores range from -15 (Nutri-Score of "A") to 40 (Nutri-Score of "E"), with lower scores indicating a more healthful product selection.
