Functional status of school-aged children with Down syndrome

Objective : To field test, in questionnaire format, the Functional Independence Measure for Children (WeeFIM, a schedule usually administered by interview) on parents of a cohort of school-aged children with Down syndrome. Methods : The parents of 211 Western Australian children with Down syndrome participated in the present study, representing 79.9% of all children with Down syndrome in the State. Subjects were identified using two sources: (i) the Birth Defects Registry; and (ii) the Disability Services Commission. Results : The total WeeFIM score was 106.2 +/- 17.0 (mean +/- SD) out of a possible 126. Girls scored higher than boys (108.6 vs 103.6; P = 0.05). Scores increased across all age groups (P < 0.0001), even relative to normative data. Performance was strongest in the transfer and locomotion domains and weakest in social cognition. Conclusion : We found that severe functional limitations are rare in school-aged children with Down syndrome. Some support and supervision are required for complex self-care, communication and social skill tasks. This study demonstrates the feasibility of using the WeeFIM for collecting population survey data in children with developmental disability. This may be useful for the longitudinal tracking of such populations, as well as the monitoring of response to interventions.
