To examine the contribution of motor ability and 'performance' mental ability on functional skills in children with Down syndrome (DS).
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.
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).
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.
探讨运动能力和“操作”智力对唐氏综合征（DS）患儿功能技能的影响。
采用结构方程模型方法来检验运动能力、操作智力与功能状态之间的关系。功能状态通过儿童残疾评估量表（PEDI）进行评估，运动能力通过儿童运动评估量表（M-ABC）进行评估，操作智力通过粗形板（GFB）进行评估。荷兰唐氏综合征基金会挑选的65名DS患儿被邀请参与该研究。使用AMOS软件，采用Bollen-Stine自助法对数据进行分析。卡方值（Chi2）和规范拟合指数（NFI）用作拟合优度指标。
模型拟合良好（卡方值（Chi2）4 = 1.35，p = 0.85；规范拟合指数（NFI）= 0.99）。“功能状态”解释了模型中70%的方差。标准化回归权重表明，与操作智力相比，运动能力是DS患儿功能状态更好的预测指标（0.96对0.17）。
5至7岁唐氏综合征患儿的功能活动受限似乎与运动能力水平的关系比与操作智力水平的关系更大。
