Abstract
The present investigation examined the extent to which girls with Attention-deficit Hyperactivity Disorder (AdHD) differed from AdHD boys and normal girls. Teacher ratings of child psychopathology, clinic observations, measures of attention span, impulse control, achievement, intelligence and memory were taken and used to assess group differences. Findings did not consistently support differences between AdHD girls and boys, although differences were found between the AdHD and normal girls.
