This study aims to determine which front-of-package label design is most effective at helping Latino consumers identify and choose healthier products, as well as explore whether the benefits of different front-of-package label designs differ by English proficiency. A Latino-focused panel company will recruit 4,000 US Latino adults of parental age (18-55 years), approximately 50% of whom will have limited English proficiency.
In a between-subjects experiment, researchers will randomize participants to 1 of 4 types of front-of-package label designs: a numerical label, an interpretive text-only label, an interpretive label with a magnifying glass icon, or separated interpretive labels with a magnifying glass icon. Participants will view their assigned label design on 3 similar products (each product high in either 1, 2, or 3 nutrients of concern) and complete selection tasks. These tasks will be repeated 3 times, each time with a different type of product (i.e., frozen meals, frozen pizzas, and frozen desserts), with the products displayed in random order.
