I also did the questionnaire but I have to admit a lot of red flags went up. Too many leading questions and assumptions in the answers with little space or options for something not on your list. How about "other" or "not applicable"? Of course, people could skip the question in that case, but does a skipped question mean they couldn't answer it/wouldn't answer it/or just missed it? Also a lot of either/or (including the true/false) questions which limits people to choosing something that may not reflect their reality. Having some sort of gradation of responses (strongly agree/agree/disagree/strongly disagree) would probably give better results. Also, some of the questions are not clear as to what specifically you are referring to.
I don't mean to be nit-picky, but I make a lot of questionnaires for my job, and when I answer them personally I want to feel that it's been worth my time.
