It's hard to not self-diagnose using this screener when it says: > So if you score 4 out of 6, the chance you actually have ADHD is: 3.5% / (3.5% + 0.5%)

It's hard to not self-diagnose using this screener when it says: > So if you score 4 out of 6, the chance you actually have ADHD is: 3.5% / (3.5% + 0.5%) = 87.5%. Judging by the questions and responses though I find that hard to believe. Questions: 2 and 3 almost seem like a 'gimme' to answer 'Sometimes', and 4 to answer 'Often' isn't a stretch. I also find question 1 to be frequently 'Sometimes' or more unless a type-A personality. Only questions 5 & 6 seem to be directly associated (IANAD). As another comment mentions, I wonder how that percentage changes if the person is already on the autstic spectrum.
