Summary
The aim of this study is to understand the impact of front of pack labelling systems such as, warning labels and traffic light labels on food choice and negative emotional response in an eating disorder(s) population group. Participants will be recruited to take part in an online study where they will be required to make hypothetical food choices. Participants will complete a baseline no label task, before being randomly assigned to (1) warning label group, (2) traffic light label group, or (3) no label group in which they will complete the same task a second time (mixed design). Each participant, irrespective of the group will be asked to complete five trials within the main task. Participants will view a selection of six packaged food items for scenarios involving labels predominately relating to (1) sugar, (2) salt, (3) fat, (4) saturated fat, and (5) calorie content of the food products. Three items will be 'high in' that particular nutrient and three items will not be high in that nutrient. Participants will be shown all six options at once and will be asked to choose one item. In total, participants will choose five different items, one from each trial. After participants have made their food choices for the second task, they will be asked questions about the task they have just completed.
