The Efficacy of Front-of-package Labelling Schemes: an Experimental Study

Behavioural: Nutrition Rating Systems (shown on the online survey and the mobile app) provide consumers with an interpretation of the healthfulness of a food or beverage, by indicating the levels (low=green, moderate=amber, high=red) of sodium, saturated fat and sugar in a product based on modified Food Standards Australia New Zealand (FSANZ) criteria.

Behavioural: Nutrition Rating Systems (shown on the online survey and the mobile app) provide consumers with an interpretation of the healthfulness of a food or beverage product by indicating the number of stars awarded to a product, from 0.5 to 5 stars, based on modified Food Standards Australia New Zealand (FSANZ) nutrient profiling criteria.

"Behavioural: Nutrition Rating Systems (shown on the online survey and the mobile app) provide consumers with an interpretation of the healthfulness of a food or beverage product by indicating with a warning label products that are high in sodium, saturated fat and sugar, based on a percent daily value (%DV) greater than 15% for individual products and 30% for combination dishes."

This is embedded within each condition to inform and educate consumers about the labelling condition/intervention to which they are randomized. All participants are assigned to an app task to view 20 products and see the 'rating' these products would get according to their condition.
