Brief Summary
The effect of three front of pack (FOP) labeling schemes (Mexican Guideline Daily Amounts (GDA), Ecuador's Multiple Traffic Light (MTL) and Chilean Warning Labels (WL) in red) on purchasing intentions was evaluated using a randomized experiment of an online shopping simulation. The study employed an online grocery store developed for this purpose to simulate a shopping situation.

Outcome Measures
Primary Outcomes (2)
Mean nutritional quality of the shopping cart
The Nutrient Profiling Scoring Criterion model was used as the main measure to evaluate the nutritional quality of the shopping cart.
On the date of randomization
Mean nutritional quality of the shopping cart (negative nutrients)
The Nutrient Profiling Scoring Criterion baseline score, considering only negative nutrients, was used to explore a nutritional quality measure consistent with the key nutrients evaluated.

Study Arms (3)
Mexican Guideline Daily Allowance (GDA)
ACTIVE COMPARATORGuideline Daily Amounts (GDA) is a purely numerical and reductive labeling system, indicates the grams and percentages (according to the guideline-based daily intakes) per portion of kilocalories, saturated fats, other fats, sugars, and sodium, with no specific judgement, opinion or recommendation.
Ecuador's Multiple Traffic Light (MTL)
EXPERIMENTALMultiple traffic light labels, an interpretive nutrient-specific FOP label, use the typical traffic light colors (green, yellow/amber, red) and text descriptors to indicate the high, medium, or low content of total fat, sugar and salt.
Chilean Warning Labels in Red
EXPERIMENTALWarning Labels (WL), another nutrient-specific interpretive FOP labelling scheme, include 'high in' symbols for products that exceed limits of energy, sodium, sugar and saturated fat.
Interventions
All food items displayed the corresponding GDA label in the lower left corner of the front of the package.
All food items displayed the corresponding MTL label in the lower left corner of the front of the package.
Food products were labeled with "High in" labels In the lower left corner of the front of the package. In total, 37 of the 60 food products in the shopping site did not display a WL.
Participants viewed a short (less than 1 min) video explaining how to interpret the label.
Eligibility Criteria
You may qualify if:
- Consuming at least one of the five food groups included in the shopping site (salty snacks, beverages, dairy products, breakfast cereals and ready-made foods)
- Shopping for groceries at least twice per week
You may not qualify if:
- Working in the food and beverage industry
- Having any of their direct family members working in the food and beverage industry
