• 1 other identifier: 803194 1B4
• Study Type: interventional
• Target: 1,800

Brief Summary

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).

Conditions

Diet, Healthy; Food Selection

Keywords

kcal labelling; PACE labelling; portion size; socio-economic position

Outcome Measures

Primary Outcomes (1)

• Total self-served energy (kcal)

  Energy content of the portion selected for each dish.

  10 minutes (the time frame denotes time taken to perform the portion selection task and there is no follow up)

Secondary Outcomes (2)

• 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)

Study Arms (4)

Kcal labelling

EXPERIMENTAL

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).

Behavioral: Kcal labelling

PACE labelling

EXPERIMENTAL

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.

Behavioral: PACE labelling

Kcal and PACE labelling

EXPERIMENTAL

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).

Behavioral: Kcal labelling; Behavioral: PACE labelling

No labelling

NO INTERVENTION

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.
