I completed it! Some very good questions in there, I'll be interested to see what you do with your results!
I agree that the "continue" part could make it difficult to respond for some people, but I figured it's not like I have NO added complexity to my life and health because of diabetes, even if I don't have capital-c Complications to speak of. So I answered it that way. But Vitali, you may need to give some special consideration to your results from that question, considering that people with no complications may not have known how to answer it correctly.
Questions about religion have to do with your personality. It's fairly well established in psychology research that certain personality types correlate with certain types of belief systems, including religious and political beliefs. Since the research is about squaring up personality traits with how one copes with diabetes, they do need a measure for that. It's actually quite a good method because it's indirect. If you ask people "are you such and such kind of a person" they're likely to respond with whatever makes them look best. If you instead ask them how they tend to feel or act in certain areas of personal belief they're more likely to be honest and you can then compare that with other research that's already been done on personality and those types of beliefs.
We have had questionnaires on here that go about this very clumsily, where they ask you things like whether you believe in God or other questions that are specific to certain religions, those are a bit too pointed and say more about the preconceptions of the researcher (i.e. that everyone has a similar religion to them) than anything else. The point is not about the religion in itself, or the politics in itself, but whether and how strongly you hold to certain systems of social organization.
Vitali here has definitely done his homework on study design as far as I can tell and it pleases me to see it! I hope you get many responses and please do keep in touch!
