Speaking just for myself, John, I never complained about any of the questions being "offensive" or too personal. I was speaking to the validity of the study structure. I read and share studies and research methodology in my professional life and am aware of certain standards for studies in order for their results to be both valid and meaningful. I would love for there to be professional studies done on the importance of the DOC to the lives of PWD's, but shoddily constructed research can hurt, not help us.
As for "airing personal lives, dirty laundry and so on..to the world"...some of us find comfort, support and increased knowledge from doing so on here, if you don't that's certainly a personal choice.
