A disorder of hyperactivity does exist in the Chinese culture, displaying the same kinds of symptomatology and external correlates as in the West. The prevalence rates of hyperkinetic disorder and ADDH in Chinese schoolboys are on the low side when compared to those reported in Western studies.

Conners' Teacher's Rating Scale (CTRS) was applied to 914 children, a representative sample of the total population of normal primary school children (age 6-12) in Hong Kong. Both interrater and test-retest reliability were satisfactory. On all the subscales, the scores lay on the high side when compared to results of western countries. When factor analysis was carried out, the main difference from other studies was that the conduct problem factor and hyperactivity factor were combined. There was a very significant sex effect with boys having much higher total and subscales scores of conduct problem, inattention and hyperactivity whereas the girls were rated significantly higher on the subscales of anxiety-tension.
