Summary

This study aims to use the Multiphase Optimization Strategy (MOST) to build and optimize a multi-component intervention that improves diet quality. The investigators will evaluate the effects of evidence-based public health interventions on consumers' diet quality via a web-based grocery store "NUSMart" and then identify a multi-component intervention that includes only those interventions meaningfully affecting diet quality.

Conditions

  • Diet Quality

Interventions

BEHAVIORAL

Explicit Tax

To impose an explicit tax on food and beverage items that are eligible for red stop-sign food logos (explained in Intervention 2) as less healthy foods. Explicit tax shows pre-tax prices and a label indicating that the price includes a corresponding tax on the less healthy products. Food and Beverages: we will impose a 20% tax on sales price of the food items

BEHAVIORAL

Food Labels (with the summary of healthiness of shopping baskets & targets)

To provide the green circle 'healthy choice' food label to items with Nutri-Score "A" and "B", the amber circle 'in between healthy and unhealthy choice' food label to items with Nutri-Score "C", and the red stop-sign 'less healthy choice' food label to items with Nutri-Score "D" and "E". In the presence of food labels, * Video: subjects will watch a video briefly explaining the food labels on the store. * My Cart Summary: subjects will be provided a live visual indicator of the healthiness of shoppers' current basket with the recommended healthy baskets goals.

BEHAVIORAL

Ordering

To order food items by Nutri-Score (high to low).

BEHAVIORAL

Within-Group Substitution

To provide substitutes within corresponding food categories that are better than the items that subjects chose in terms of Nutri-Score based on the similarities of price, primary ingredients, flavor, and other characteristics.
