About this trial
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.

Trial outcomes
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.
Time frame
During exposure to intervention (i.e., study stimuli), assessed during one-time online 10-minute survey.Secondary outcomes
1
Perceived message effectiveness
Perceived message effectiveness will be measured by survey through a three-item scale. Items will inquire about how much participants perceive the labels to (1) discourage them from wanting to buy products with non-nutritive sweeteners for their child, (2) make them concerned about the health effects of their child consuming products with non-nutritive sweeteners, and (3) make buying products with non-nutritive sweeteners for their child seem unpleasant to them. Response options will be on a 5-point scale between "not at all" (coded as 1) and "very much" (coded as 5), with higher scores representing a higher perceived message effectiveness. Each participant's responses to each item will be combined to obtain their final score on the outcome.
Time frame
During exposure to intervention (i.e., study stimuli), assessed during one-time online 10-minute survey.2
Attention drawn by the labels
How much attention the labels draw will be measured by survey. Response options will be on a 5-point scale between "not at all" (coded as 1) and "extremely" (coded as 5), with higher scores representing more attention drawn by the labels.
Time frame
During exposure to intervention (i.e., study stimuli), assessed during one-time online 10-minute survey.3
Ease of understanding the labels
How easy or difficult the information presented by the labels is to understand will be measured by survey. Response options will be on a 5-point scale between "very difficult" (coded as 1) and "very easy" (coded as 5), with higher scores representing higher ease of understanding the labels.
Time frame
During exposure to intervention (i.e., study stimuli), assessed during one-time online 10-minute survey.4
Support for the labels
How much participants would oppose or support a law requiring the labels products with too much sugar, salt, and fat will be measured by survey. Response options will be on a 5-point scale between "strongly oppose" (coded as 1) and "Strongly support" (coded as 5), with higher scores representing higher support for the labels.
