A two-step procedure for the identification of children with developmental co-ordination disorder in Singapore.

The prevalence of Developmental Coordination Disorder (DCD) among 6- to 9- year-old Singaporean primary school children was studied from a random sample (N = 427) through a two-step identification procedure contained within Henderson's and Sugden's Movement Assessment Battery for Children. The prevalence rate from this two step procedure was 4% when the first step included the bottom 15% of the random sample. The two-step procedure moves towards fulfilling the diagnostic criteria for DCD set out by the American Psychiatric Association (DSM-IV) and the World Health Organisation (ICD-10) of a serious motor impairment in the development of motor coordination and significant interference with the activities of daily living not due in children to mental retardation or a known physical disability.
