About

The aim of this study is to compare the impact of 5 different types of front of package (FOP) food and beverage labels: 1) calorie labels [control], 2) green labels on healthy foods, 3) red/yellow/green labels on less healthy/moderately healthy/healthy foods, 4) physical activity calorie equivalent labels, and 5) "High in" nutrient warning labels) on consumers' beverage and snack selections.

Full description

This project involves an online randomized experiment. We are working with an external survey company that will recruit 8,000 participants to complete an online survey in which they will be randomized to one of the five different label conditions: 1) calorie labels (control condition); 2) single green traffic light labels (on healthy foods); 3) multiple traffic light labels (red traffic light labels applied to less healthy foods, yellow applied to moderately healthy foods, and green on healthy foods); 4) physical activity labels (calorie content displayed in terms of physical activity equivalents); 5) "High in" warnings (applied to all products exceeding thresholds for calories, saturated fat, sugar, or sodium content). Participants will be instructed to select products to purchase in a mock vending machine. After purchasing their products, they will be asked to answer questions about their perceptions of the different labels.

Control
Active Comparator group
Description:
Calorie labels shown on front of product packaging
Treatment:
Behavioral: Exposure to calorie information
Green labels
Experimental group
Description:
Green label added to front of product packaging for healthy products; no additional labels shown for "less healthy" products
Treatment:
Behavioral: Exposure to healthy labels only
Behavioral: Exposure to calorie information
Traffic light labels
Experimental group
Description:
Red/yellow/green labels added to front of product packaging for less healthy/moderately healthy/healthy products, respectively
Treatment:
Behavioral: Exposure to healthiness information
Behavioral: Exposure to calorie information
Physical activity calorie equivalent labels
Experimental group
Description:
Labels added to front of product packaging that display products' calorie content in terms of physical activity required to burn those calories
Treatment:
Behavioral: Exposure to physical activity equivalents
Behavioral: Exposure to calorie information
"High in" nutrient warning labels
Experimental group
Description:
Labels added to front of product packaging that signal when the product exceeds thresholds for sugar, sodium, saturated fat, or calorie content
Treatment:
Behavioral: Exposure to calorie information
Behavioral: Exposure to "high in" nutrient warning labels
