Notes
ACE touchscreen question "How many weeks was the longest period when you were uninterested in things or unable to enjoy the things you used to?"
Question was introduced part way through fieldwork in April 2009.
The following checks were performed:
- If answer < 1 then rejected
- If answer > 999 then rejected
Field 5375 was collected from participants who indicated they have been uninterested in things or unable to enjoy things they used to for at least a week, as defined by their answers to Field 4631
Coding 100291 defines 2 special values:
- -1 represents "Do not know"
- -3 represents "Prefer not to answer"
