Item 3: How many days last week did you miss work, including housework, because of fibromyalgia?

If the participant is off sick or has a disability due to FM, I imagine the correct answer must be 7. Is it correct? If she works, she marks the days in which has missed work due to FM.

Item 4: When you worked how much did pain or other symptoms of your fibromyalgia interfere with your ability to do your work, including housework?

Since the scale refers to the previous week, does this question refer to the impact suffered at work during last week or to the time when she was working?

I couldn’t contact with the authors, so I hope someone will be able to help! :)
