简要总结
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.
详细描述
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.
Hypotheses:
Both WL and TLL will affect food choice (vs. control), but WL will have a larger impact on discouraging unhealthy food choices than TLL.
Both WL and TLL will affect calorie and nutrient selected (vs. control), but WL will have a larger impact than TLL.
WL will have a larger impact on negative emotional responses than TLL.

研究组 & 干预措施
Warning labels
Products in the food choice task will feature warning labels if high in sugar, salt, fat, saturated fat, and/or calories.
干预措施: Front-of-pack nutrition labelling (Behavioral)
No label
Products in the food choice task will not feature a nutrition label.
干预措施: Front-of-pack nutrition labelling (Behavioral)
Traffic light label
Products in the food choice task will feature a traffic light label.
干预措施: Front-of-pack nutrition labelling (Behavioral)
结局指标
主要结局
Total number of unhealthy food items selected
时间窗: Measured in both surveys, immediately after the intervention. The baseline task must be completed between 24 hours and 1 week prior to completing the second task.
Total number of selected unhealthy food items across the 5 trials will be calculated. Unhealthy food items will be coded as items eligible for a WL or a red traffic light label for the task-specific nutrient e.g., red for salt in crisp trial.
次要结局
- Total calories, salt, sugar, fat, saturated fat from selected food items(Measured in both surveys, immediately after the intervention.)
- Negative emotional response(Measured in survey 2, immediately after the intervention.)
- Positive and negative affect schedule (PANAS)(Measured in both surveys, pre-intervention and immediately after the intervention.)
- Reactance and avoidance(Measured in survey 2, immediately after the intervention.)
- Acceptability of labels(Measured in survey 2, immediately after the intervention.)
- Perceived message effectiveness (PME)(Measured in survey 2, immediately after the intervention.)
- Label awareness(Measured in survey 2, immediately after the intervention.)
- Label influence(Measured in survey 2, immediately after the intervention.)
