Remember there are no tests for adhd. Some people are told they have to take a computer test with flashing lights and buttons. Some people are told they have to take other tests as well. The conner's scale is good for self evaluation and for another family member to give their opinion about your behaviors. Adhd is diagnosed by a psychiatrist using self evaluations from patients and patient history. A lot of people are turned away because they fail the "tests". And many people are turned away because they were not diagnosed as a child. That is truly ridiculous because unless you have parents and teachers that are totally tuned into adhd, you can easily be overlooked, undiagnosed or misdiagnosed. Many adults with adhd had it their whole lives but were unable to get diagnosed or had other mental health issues that took priority.
