PURPOSE: To examine the contribution of motor ability and 'performance' mental ability on functional skills in children with Down syndrome (DS). METHOD: A structural equation modelling approach was used to test the relation between motor ability, performance mental ability and functional status. Functional status was assessed with the Pediatric Evaluation Disability Inventory (PEDI), motor ability with the Movement Assessment Battery for Children (M-ABC), and performance mental ability was assessed with the Gross-Form Board (GFB). Sixty-five children with DS, selected by the Dutch Down Syndrome Foundation, were asked to participate in the study. Data were analysed with the programme AMOS using the Bollen-Stine bootstrap method. Chi2 and NFI index were used as goodness-of-fit indices. RESULTS: The fit of the model was good (chi2 4 = 1.35, p = 0.85; and NFI = 0.99). 'Functional status' explained 70% of the variance in the model. Standardized regression weights indicated that motor ability was a far better predictor of functional status of children with DS than performance mental ability (0.96 vs. 0.17). CONCLUSIONS: Limitations in functional activities of 5 to 7-year-old children with Down syndrome seem to be more related to the level of motor ability than to the level of performance mental ability.
