Attention deficit hyperactivity disorder: an epidemiological screening method.
Multistage identification, an epidemiological screening method of diagnostic assessment, was used to identify attention-deficit hyperactivity disorder (ADHD) in 1,490 elementary-school students. Children diagnosed with ADHD exhibited more impairment on adjustment measures and were more likely to have coexisting disruptive behavior disorders than were children diagnosed as subclinical non-ADHD.
