Comparing the Effects of Front-of-Package Labeling Schemes in Indonesia
What this study is about
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.
View original scientific description
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.
Interventions
BEHAVIORAL
Nutrient Warning Label
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.
BEHAVIORAL
Nutri-Level
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.
Primary outcome measures
Correct identification of products high in nutrients of concern
Time frame: During exposure to intervention (i.e., study stimuli), assessed during one-time online 10-minute survey.
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.
Purchase intentions
Time frame: During exposure to intervention (i.e., study stimuli), assessed during one-time online 10-minute survey.
How likely participants would be to buy this product in the next week if it were available in a store will be measured by survey. Response options will be on a 5-point scale between "extremely unlikely" (coded as 1) and "extremely likely" (coded as 5), with higher scores representing higher intent to purchase the product.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
