Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Purchasing intentions will be assessed using an experimental web-based supermarket designed to look like a regular online grocery store. The supermarket includes 269 unique products divided into 4 categories: dairy products, processed meat/delicatessen, savory and breakfast/sugary products. Each category is then separated into specific products families like yogurt, milk, cheese, etc. for the dairy products category. Inside a food family, the selection of foodstuffs will be made to obtain a representative sample of the products commonly sold in French supermarket. For each type of products, at least two variants are proposed. Products are retailers or manufacturers branded. Categories of products that are not usually bought each week, or which are likely to be bought from different sources are not included on the web-based supermarket.
Participants are asked to simulate a shopping situation: they have to select a week worth of food for their family among proposed products. If the user is not able to find a product he/she usually buy, the instruction is to select similar product among proposed ones.
Information provided for each product is: name, price and the picture with the FOP label/or not according to the experimental condition to which the participant is allocated. A brief explanation of the FOP label used is also given.
