Brief 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.

Outcome Measures
Primary Outcomes (2)
Correct identification of healthiest product
Correct identification of healthiest product will be measured by survey. Responses will be coded in a dichotomous 0-1 range, where 1 indicates that the participant correctly identified the healthiest product and 0 indicates that the participant incorrectly identified one of the other two less healthy products as the healthiest product.
During exposure to intervention (i.e., study stimuli), assessed during one-time online 10-minute survey.
Correct identification of least healthy product
Correct identification of least healthy product will be measured by survey. Responses will be coded in a dichotomous 0-1 range, where 1 indicates that the participant correctly identified the least healthy product and 0 indicates that the participant incorrectly identified one of the other two healthier products as the least healthy product.
During exposure to intervention (i.e., study stimuli), assessed during one-time online 10-minute survey.
Secondary Outcomes (2)
Correct identification of products high in nutrients
During exposure to intervention (i.e., study stimuli), assessed during one-time online 10-minute survey.
Selection of healthiest product for purchase
During exposure to intervention (i.e., study stimuli), assessed during one-time online 10-minute survey.

EXPERIMENTALInterventions
Labels that list the amount and percent of daily value of added sugar, sodium, or saturated fat, modeled after Guideline Daily Amounts labels.
Interpretive text-only labels that state when a product contains high amounts of added sugar, sodium, or saturated fat.
Interpretive labels that state when a product contains high amounts of added sugar, sodium, or saturated fat, containing a magnifying glass icon.
Interpretive labels that state when a product contains high amounts of added sugar, sodium, or saturated fat, containing a magnifying glass icon. Each nutrient will be on a separate label.
