Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Participants: Participants will consist of approximately 2,500 individuals 18 and older with at least one child ages 1-5. The child 1-5 who had their birthday most recently must have consumed at least one fruit drink in the previous week. Additionally, they will live in the United States and identify as non-Hispanic black, non-Hispanic white, or Hispanic. The panel research company Kantar will recruit individuals from its pool of potential individuals.
Procedures (methods): The investigators will randomize participants to one of 12 versions of a virtual convenience store (iShoppe) and then the participants will complete two shopping tasks in the store. They will select two beverages (task 1) for their child 1-5 who had their birthday most recently, and they will select a snack (task 2) for that same child. After completing the shopping tasks, the participant will complete a survey in Qualtrics. The survey will ask a series of questions about the beverages and snacks (e.g., perceived healthfulness, perceived appeal, intentions to consume products). Questions will also include standard demographic and health related variables.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Setting: The trial will take place in a virtual convenience store setting created for researchers to examine how store and product characteristics influence consumer purchases in a controlled but realistic environment.
Recruitment: Participants will be recruited online through Kantar's currently available panel participants. Interested potential participants will complete a screener online, and if they are eligible, they will be redirected to the consent form.
Informed consent: Participants will view an online consent form prior to participating in the study, They will acknowledge their consent by proceeding onto the study.
Randomization: After acknowledging consent, participants will be randomized to one of 12 versions of the store(see trial arms). Participants will have an equal chance to be randomized to one of the arms of the store.
Assessment: Participants will enter the virtual convenience store and be given a shopping task to select 2 beverages (task 1) for their child age 1-5 who celebrated their birthday most recently. The participant will have to select between 100% grape juice and a grape-flavored fruit drink, and they will have to select between water and an apple-flavored fruit drink. After selecting two beverages, the participant will then be directed to complete a snack shopping task (task 2). After completing the two shopping tasks, the participant will be redirected to an online survey to complete. Participation in the study will last approximately 15-18 minutes.
Trial arms: All participants will complete two shopping tasks where they have to (1) choose between a grape fruit drink and a 100% grape juice, and choose between an apple fruit drink and water, and (2) choose between a snack with a nutrient warning label or a snack with no warning label. There will be 4 versions of the fruit drinks that participants will be randomized to. They will see either a fruit drink with no claim (control) or a fruit drink with 1 of 3 claims ("No artificial sweeteners," "100% vitamin c daily value," "100% all natural"). For the snack with the nutrient warning label, participants will see either a control label (barcode) or a nutrient warning label (text or graphic).
