Notes
ACE touchscreen question "In a typical DAY, how many hours do you spend watching TV? (Put 0 if you do not spend any time doing it)"
The following checks were performed:
- If answer < 0 then rejected
- If answer > 24 then rejected

If the participant activated the Help button they were shown the message:
If the time you spend watching TV varies a lot, give
the average time for a 24 hour day in the last 4 weeks.
