研究概览
简要总结
Participants will take part in an online survey. They will be asked to choose the amount of food they would like to eat based on pictures of 18 dishes sequentially displayed on the screen. They will be randomly allocated to four different groups: kcal labelling, PACE labelling (Physical Activity Calorie Equivalent: minutes to walk to burn off the calories), kcal and PACE labelling combined, no labelling, in a between subject design. The main outcome variable is the total "self-served" energy for each dish (in kcal).

研究组 & 干预措施
Kcal labelling
Participants allocated to this group will see on the screen the amount of food increasing or decreasing based on how many times they tap on the corresponding keys and a real-time kcal counter synchronised with the food amount changes (i.e., increasing/decreasing).
干预措施: Kcal labelling (Behavioral)
PACE labelling
Participants allocated to this group will see on the screen the amount of food increasing or decreasing based on how many times they tap on the corresponding keys and a real-time PACE counter (as minutes needed to walk to burn off the calories) synchronised to the food amount changes (i.e., increasing/decreasing) with 4 min being equivalent to 20 kcal.
干预措施: PACE labelling (Behavioral)
Kcal and PACE labelling
Participants allocated to this group will see on the screen the amount of food increasing or decreasing based on how many times they tap on the corresponding keys and a real-time kcal and PACE counters synchronised to the food amount changes (i.e., increasing/decreasing).

干预措施: PACE labelling (Behavioral)
No labelling
Participants allocated to this group will only see on the screen the amount of food increasing or decreasing based how many times they tap on the corresponding keys.
结局指标
主要结局
Total self-served energy (kcal)
时间窗: 10 minutes (the time frame denotes time taken to perform the portion selection task and there is no follow up)
Energy content of the portion selected for each dish.
次要结局
- Kcal influence(3 minutes (the time frame denotes time taken to fill in the debriefing questionnaire and there is no follow up))
- PACE influence(3 minutes (the time frame denotes time taken to fill in the debriefing questionnaire and there is no follow up))
