Notes
ACE touchscreen question "Does your work involve shift work?"
If the participant activated the Help button they were shown the message:
If you have more than one 'current job' then answer this question for your MAIN job only. Shift work is a work schedule that falls outside of the normal daytime working hours of 9am-5pm. This may involve working afternoons, evenings or nights or rotating through these kinds of shifts.
