Notes
ACE touchscreen question "How many periods have you had when you were uninterested in things or unable to enjoy the things you used to for at least a whole week?"
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 5386 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"
