Data from the large standardization project can reveal important information about the diagnosis of ADHD. For example, the significance of the Impairment data comparing the general population with diagnosed ADHD is the fact that they show an excess of diagnoses were made without reference to impairment. A substantial portion of responses to the question of degree of impairment among children with a diagnosis of ADHD in the sample is "Never," this despite the fact that approved DSM standards were supposedly used.
Diagnosing from symptoms without evidence of impairment is simply shoddy practice!
