Understanding Food Choices (Aim 2)

This study aims to use the Multiphase Optimization Strategy (MOST) to build and optimize a multicomponent intervention that improves diet quality. The investigators have evaluated the effects of evidence-based public health interventions on consumers' diet quality via a web-based grocery store "NUSMart" as part of Aim 1 of this study. Considering that the goal is to identify promising interventions that may optimize online grocery platforms, the investigators used Aim 1's results to assemble a multicomponent intervention that would significantly affect diet quality: a combination of three behavioral nudges that include food labels \& real-time feedback, ordering, and healthier substitute offers (a subset of the interventions examined in Aim 1). Aim 2 study aims to rigorously evaluate this multicomponent intervention.
