Notes
ACE touchscreen question "In an average WEEK, how many measures of spirits or liqueurs would you drink? (there are 25 standard measures in a normal sized bottle; spirits include drinks such as whisky, gin, rum, vodka, brandy)"
The following checks were performed:
- If answer < 0 then rejected
- If answer > 250 then rejected
- If answer > 100 then participant asked to confirm
If the participant activated the Help button they were shown the message:
For mixed drinks that contain spirits or liqueurs, count one bottle
as one measure. There is a question later on alcopops
