Notes
ACE touchscreen question "How many slices of bread do you eat each WEEK?"
The following checks were performed:
- If answer < 0 then rejected
- If answer > 250 then rejected
- If answer > 50 then participant asked to confirm
If the participant activated the Help button they were shown the message:
For other types of bread:
- one bread roll = 2 slices
- one pitta bread = 2 slices
