title: Behavioural problems among preschool age children in Shanghai: analysis of 3,000 cases.
abstract: This paper reports the preliminary findings of an epidemiological study of 3,000 children ages four and five in the Shanghai area. Associations were investigated between problems in the narrow band syndromes of the Achenbach Child Behavior Checklist and certain sociodemographic variables (a one-child family, other social circumstances related to the family). No strong evidence emerged of a distinct psychopathology associated with children from single-child families, although there was a significant correlation between being an only child and having social withdrawal problems. Delinquent behaviour and hyperactivity were more frequent among boys, while somatic complaints, schizoid or anxious, and depression were more frequent among girls. A four year follow-up study of 433 children from the original group who continued to have problems showed a marked increase in hyperactive syndrome problems; this suggests the existence of a clinically identifiable group of behaviourally disturbed children. Early identification allows for early treatment and comparison of the relative efficacy of early and late treatment approaches.
