New Zealand Health Survey - opportunity to include ME/CFS questions

Sorry if I’m being obtuse: how are the answers graded or used to determine disability?

 

The survey* asks about "difficulties you may have doing certain activities because of a HEALTH PROBLEM" - so it picks up disability irrespective of what illness/disease/condition causes it.

There are 6 questions:

1. Do you have difficulty seeing, even if wearing glasses?
2. Do you have difficulty hearing, even if using a hearing aid?
3. Do you have difficulty walking or climbing steps?
4. Do you have difficulty remembering or concentrating?
5. Do you have difficulty (with self-care such as) washing all over or dressing?
6. Using your usual (customary) language, do you have difficulty communicating, for example understanding or being understood?​

And the answer options for each question are:

a. No-no difficulty
b. Yes –some difficulty
c. Yes –a lot of difficulty
d. Cannot do at all​

What is done with the completed answers would depend on the context in which the survey is done I expect.
