Special regard is given to situational differences, with preference given to teacher reports over parent reports. The age of onset is specified as before age seven, with at least six months duration. Conditions not included are Schizophrenia, Affective Disorder, or Severe or Profound Mental Retardation.
DSM-III-R (APA, 1987)--Attention-Deficit Hyperactivity Disorder in Children: The criteria include 14 items of which at least 8 must be present before seven years of age.
