Study Overview
Brief Summary
Purpose: To better understand the impact of different front-of-package labels (FOPLs) on consumer purchasing intentions and ability to identify unhealthy foods.
Participants: ~8,000 Colombians, recruited from Offerwise, that are 18 years or older.
Procedures (methods): Participants will be randomly assigned to view images of food and drink products with either a nutrient warning label, Guideline Daily Amount label, Nutriscore label, or no-label control. They will be asked a series of questions about the products and the labels (excluding control group) on them. Questions will also include standard demographic and health related variables.
Detailed Description
Participants will be recruited from Offerwise (an online panel research company). Following online consent, participants will be randomly assigned to view different labels (explained below) on food and drink packaging. Participants will answer self-reported responses to the content (e.g., elaboration, beliefs, perceived healthfulness). After being randomized to one of the four groups and answering questions (e.g. which product is healthier, which product would you buy), the participant will see all three labels and select which is most dissuading from consuming a product high in a nutrient. At the end, the participant will answer demographic questions.
Participants will be randomized to see either a no-label control or 1 of 3 nutrient labels. The participants will see 5 types of products with the labels (fruit drinks, yogurt, sliced bread, cookies, and breakfast cereal).
Nutrient labels:
- Guideline Daily Amount label
- Nutriscore label
- Adapted Peruvian nutrient warning label (high in sugar, high in saturated fat, high in salt/sodium)
