Notes
ACE touchscreen question "How many minutes did you usually spend walking on a typical DAY?"
The following checks were performed:
- If answer < 0 then rejected
- If answer > 1440 then rejected
- If answer < 10 then participant asked to confirm
- If answer > 300 then participant asked to confirm
If the participant activated the Help button they were shown the message:
Count the number of minutes that you usually spend walking in one day.
If the time you usually spend walking on each day of the week varies a
lot, give an average of the time you spend walking. For instance if on
one day of the week you usually walk for 4 hours but on the other day
you walk 2 hours then give the average - that is 3 hours.
