One of the first questions everyone has is: Do I have ADD/ADHD? There is no one definitive questionnaire. There are several good questionnaires authored by prominent physicians & the government itself. Here is a list of links to ten different questionnaires (we make no representation as the accuracy of any of the questionnaires). CHECKLISTS / RATING SCALES
