Conners' Teacher's Rating Scale—A Validity Study in Hong Kong

Abstract
The validity of the Conners'' teacher''s rating scale (CTRS) in Hong Kong Chinese school children was examined. It was found that CTRS could significantly differentiate a behaviorally deviant group and the normal population; that CTRS has a strong positive correlation with the teacher''s decision to refer a child to a mental health professionals; that the CTRS by itself is not useful as a diagnostic instrument; and finally, it cannot stand alone as a screening instrument in the epidemiological study of childhood hyperactivity.
