Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Control

Participants will conduct online shopping tasks without any environmental nudges. This includes no labels, peer comparison messages, or suggested product swaps.

Group Type NO_INTERVENTION

No interventions assigned to this group

Environmental

Participants in the experimental arm will shop and receive environmental nudges in the form of labels, peer comparisons messages, and suggested product swaps.

Group Type EXPERIMENTAL

Environmental nudges

Intervention Type BEHAVIORAL

Participants will view protein, frozen meal, and snack products with eco-labels applied. For each category, they will then be instructed to select 1 item from that category they wish most to purchase. Categories will be shown in random order. If a participant selects a product with a red eco-label, they will be shown a peer comparison message and will be given an opportunity to switch to a product with a yellow or green eco-label.
