Construct validity for the Motor Development Scale (MDS) has not been established. The aim of this study was to examine whether the unidimensional model of MDS would be appropriate for children aged 4 to 6 years-old and provide construct validity for the items concerning this age group in Brazil.
A total of 938 children participated in the study (214 4-year-olds, 643 5-year-olds, and 81 6-year-olds). Confirmatory factor analysis (CFA) was used to evaluate construct validity of the MDS using a unidimensional model.
The CFA for the unidimensional model showed excellent adequacy indices for age 4: χ2(2) = 0.581, p = 0.748, comparative fit index (CFI) = 1.000, Tucker-Lewis index (TLI) = 1.090, root mean square error of approximation (RMSEA) = 0.000 (90% confidence interval [90%CI] = 0.000 to 0.093, close fit [Cfit] = 0.841); age 5: χ2(2) = 2.669, p = 0.263, CFI = 0.993, TLI = 0.980, RMSEA = 0.023 (90%CI = 0.000 to 0.085, Cfit = 0.682), weighted root mean square residual (WRMR) = 0.407; and age 6: χ2(9) = 8.275, p = 0.506, CFI = 1.000, TLI = 1.010, RMSEA = 0.000 (90%CI = 0.000 to 0.118, Cfit = 0.653), WRMR = 0.495. Reliability was good: ω = 0.87 (95%CI = 0.81 to 0.92).
The proposed unidimensional solution for the MDS provides a concise, parsimonious and reliable way to assess motor development in children aged 4 to 6 years.
运动发育量表（MDS）的建构效度尚未确定。本研究的目的是检验 MDS 的单维模型是否适用于 4 至 6 岁儿童，并为巴西该年龄段的项目提供建构效度。
共有 938 名儿童参与了研究（214 名 4 岁儿童，643 名 5 岁儿童，81 名 6 岁儿童）。使用验证性因子分析（CFA）来评估 MDS 的单维模型的建构效度。
4 岁儿童的单维模型 CFA 显示出极好的充分性指标：χ2（2）= 0.581，p = 0.748，比较拟合指数（CFI）= 1.000，Tucker-Lewis 指数（TLI）= 1.090，近似均方根误差（RMSEA）= 0.000（90%置信区间 [90%CI] = 0.000 至 0.093，接近拟合 [Cfit] = 0.841）；5 岁儿童：χ2（2）= 2.669，p = 0.263，CFI = 0.993，TLI = 0.980，RMSEA = 0.023（90%CI = 0.000 至 0.085，Cfit = 0.682），加权均方根残差（WRMR）= 0.407；6 岁儿童：χ2（9）= 8.275，p = 0.506，CFI = 1.000，TLI = 1.010，RMSEA = 0.000（90%CI = 0.000 至 0.118，Cfit = 0.653），WRMR = 0.495。信度良好：ω = 0.87（95%CI = 0.81 至 0.92）。
提出的 MDS 单维解决方案为 4 至 6 岁儿童的运动发育评估提供了一种简洁、简约和可靠的方法。
