Online Grocery Shopping study

A web-based study by The George Institute for Global Health on how people’s online grocery purchases are influenced by information presented to them.

Study description/purpose

Australians are increasingly shopping online for their groceries however, researchers don’t have much evidence on the level of influence of information available to consumers online.

The aim of this study is to understand how online grocery purchasing choices may change depending on the information being presented online

What’s involved

People who consent to participate in the study will agree to have their online grocery purchases monitored using a web-browser-extension, the Online Grocery Shopping (OGS) tool.

Other research activities include completion of surveys and dietary questionnaires, at-home blood pressure measurements using a monitor we provide at no cost to you, and provision of urine samples at a local certified pathology centre.

A small selection of participants will also be invited to participate in a telephone interview at the completion of the study asking about their thoughts, experience and suggestions for improvements on various elements of the research.
