I'll just speak for a second, if I could. I think part of the difference that you are seeing with the statistics.... The recent study, if we're talking about the same one, was, as you said, self-reported. Those numbers are not actually representative of diagnostics, because there was no mental health professional involved. It was purely a screening tool; whereas these ones here, done by the Royal Ottawa, are actually diagnoses by a mental health professional. I think that's why you're going to see a discrepancy. Those that are self-reported are going to be a lot higher, potentially because there are more people involved.
