Notes
ACE touchscreen question "Outside of your home, about how many hours per WEEK are you exposed to other people's tobacco smoke?"
The following checks were performed:
- If answer < 0 then rejected
- If answer > 168 then rejected
- If answer > 100 then participant asked to confirm
If the participant activated the Help button they were shown the message:
Please give the number of hours in a typical week over the
last year that you have been exposed to other people's tobacco
smoke in environments other than the home (include work, pubs,
restaurants etc).
