Front-of-package Label Effects in Latine and Limited English Proficiency Populations

Summary

The goal of this experiment is to examine the effects of 4 types of front-of-package food labels among a sample of Latino adults. The main questions this experiment aims to answer are:

What front-of-package label design is most effective in helping Latino and low English proficiency consumers identify healthier and less healthy food products?

What front-of-package label design is most effective in helping Latino and low English proficiency consumers choose healthier food products?

Additionally, this experiment also aims to answer the following question:

Do the benefits of front-of-package label designs differ by English proficiency and parental status?

Participants will be randomly assigned to 1 of 4 types of front-of-package label designs and view their assigned label design on 3 sets of products. Each set will display 3 similar products, each high in either 1, 2, or 3 nutrients of concern. For each set, participants will select the product that they believe to be the healthiest, least healthy, and the product that they would most want to consume. Researchers will compare results across label designs.

Conditions

Interventions

BEHAVIORAL

Guideline Daily Amounts label

Labels that list the amount and percent of daily value of added sugar, sodium, or saturated fat, modeled after Guideline Daily Amounts labels.

BEHAVIORAL

Interpretive text-only label

Interpretive text-only labels that state when a product contains high amounts of added sugar, sodium, or saturated fat.

BEHAVIORAL

Interpretive magnifying glass icon label

Interpretive labels that state when a product contains high amounts of added sugar, sodium, or saturated fat, containing a magnifying glass icon.

BEHAVIORAL

Separated interpretive magnifying glass icon label
