IMHO, great post!
Glad to hear that it has gone so well for you. Amazing what a difference good sleep can make!
To me the 'tone' of this survey is that the respondent is likely not to be compliant in use of the CPAP.
I think that the second question asking about hours of use over the last month, when using a CPAP, is problematical. Isn't the real question whether the individual used the CPAP for the entire sleep duration or not? For example if I had a busy month and only slept for 5 hours a night (average) for a month and chose 5 hours as the answer would the researcher then conclude that I took the mask off and then went back to sleep? Is question 3 intended to cover that situation?
I might be missing something here but if the survey is not really interested in how long one sleeps at night then possibly the following could be used for questions 3 and 4:
When I use the CPAP:
I you do take CPAP off prior to finishing your sleep what best describes how you use your CPAP:
*I normally take it off after a fixed amount of time (such as 3, 4, or 5 hours).
Question 4 (provider charges for non-use) almost makes my blood boil. We can get into a discussion about that if you wish.
Question 5 is interesting. Where is that money coming from? I doubt that the insurance company would be willing to allow that as a charge. If that indeed is the case then the patient is paying that money.
Question 6, bullet 8 should probably be "I hope to..." rather than "I home to..."
Question 7, you might want to include just being curious how well you sleep without it as a possible response.
Question 8 seems to assume that a person is not compliant. In the couple of years that I have had a CPAP machine there are probably only about 15 days total that I have not worn the mask all night. Two times because of facial irritation and maybe four times just to see how I slept without it (the other 9 times, travelling and its use was not convenient). When using it, I have never not used it for the entire duration of my sleep.
