The goal of this study is to examine what type of front-of-package label (FOPL) would be most effective at discouraging consumption of products high in nutrients of concern in Indonesia. The main questions this experiment aims to answer are: 1. Would nutrient warning labels be more effective at discouraging consumption of products high in nutrients of concern compared to the Nutri-Level label? 2. Would nutrient warning labels improve consumers' ability to identify unhealthy products compared to the Nutri-Level label? Additionally, this experiment also aims to determine how should nutrient warning labels be designed to most effectively discourage consumption of products high in nutrients of concern among Indonesian consumers.
Participants will complete an online randomized experiment programmed in Qualtrics. Following online consent, participants will be randomly assigned to one of two arms: 1. Nutrient Warning Label 2. Nutri-Level Label (color-coded summary nutritional label). Participants will view four different products (sweet tea, sausages, instant noodles, and yogurt) carrying their assigned label and will answer a series of questions about the products and the labels. All participants will then see nutrient warning labels with different designs in random order, and will select the label design they consider…
