DSM-IV Inattentive and Hyperactive–Impulsive symptoms assessed at ages 6, 9, and 16.

Note. At age 6, the Diagnostic Interview Schedule for Children Version 2.1–Parent report assessed DSM-III-R symptoms of ADHD; hence at age 6, only five of the nine DSM-IV Inattentive symptoms and seven of the nine Hyperactive–Impulsive symptoms were assessed. At ages 9 and 16, Versions 3.0 and IV of the Diagnostic Interview Schedule for Children, respectively, assessed all 18 DSM-IV ADHD symptoms. DSM-IV = Diagnostic and Statistical Manual of Mental Disorders (4th ed.); DSM-III-R = Diagnostic and Statistical Manual of Mental Disorders (3rd ed., rev.).
