Brief Summary
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?

Outcome Measures
Primary Outcomes (1)
Correct identification of products high in nutrients of concern
Correct identification of products as high in nutrients of concern will be measured categorically by survey. Response will be coded in a dichotomous 0-1 range, where 1 indicates that the participant correctly identified that the product was high in a nutrient of concern and 0 indicates that the participant did not correctly identify that the products was high in a nutrient of concern.
During exposure to intervention (i.e., study stimuli), assessed during one-time online 10-minute survey.

Study Arms (2)
Nutrient Warning Label
EXPERIMENTALParticipants are assigned to view food products displaying nutrient warning labels indicating that the product is high in sugar, salt, and/or fat.
Nutri-Level
EXPERIMENTALParticipants are assigned to view food products displaying a Nutri-Level summary nutrition label.
Interventions
Presentation of food products with one or more nutrient warning labels (black octagons) indicating that the product is high in sugar, salt, and/or fat.
Presentation of food products with a Nutri-Level summary nutrition label assigning a letter grade (A-D) based on sugar, salt, and/or fat content.
