To assess the validity and reliability of Family Environment Scale on Motor Development for Urban Pre-school Children (FESMDUPC) so as to provide valid and reliable tools for measuring the influencing factors from home environment on motor development of the children.
One thousand eight hundreds and twenty four preschool children from 15 kindergartens in Suzhou city were included in this study which related to reliability and validity of FESMDUPC. Data on test-retest reliability, internal consistent reliability, content validity and construct validity were assessed using the Intra-class Correlation Coefficient (ICC), Cronbach α coefficient, Item-level content validity index (I-CVI) and Confirmatory Factor Analysis (CFA). When the Observation for Measurement of the Environment Revisited was used as criteria, the criteria-related validity of MABC was assessed, using the Spearman correlation analysis.
This study showed that the ICC of all items was above or close to 0.9. The total Cronbach α coefficient was 0.875 and the Cronbach α coefficient was 0.868-0.873 when each item was deleted. Formal validity and reliability study showed that I-CVI of the 23 items was 0.79-1.00. The average I-CVI was 0.92. Results from the CFA model showed that χ2=1077.5, df=224 and χ2/df=4.810. Fit of Goodness on the other indices of the model were as follows: GFI (0.949), AGF (0.937), NFI (0.889), CFI (0.896), with each of them above or close to 0.9. The RMSEA was 0.046 which showed that the model's Fit of Goodness could be accepted. The factor loadings were all above 0.3 with statistical significance. However, according to this model, the strengths of relationship between Outside Space, Inside Space and Toy were high, so the high-step CFA of FESMDUPC was further analyzed. The model's Fit of Goodness was good. The factor loadings were all above 0.3 with statistical significance. Results showed that the Spearman Coefficient of the total score of FESMDUPC and HOME scale was 0.476 (each P<0.001). Among them only the learning staff and movement variety were comparatively and highly correlated with Toy, Parental Rearing Patterns. Spearman coefficients were all above 0.3 (each P<0.001).
The above results showed that the reliability of test-retest, the internal consistent reliability, the content validity and the construct validity of FESMDUPC were fair and had met the basic psychometric demands. FESMDUPC could be used as a quantitative tool to assess the motor development among children.
评估城市学龄前儿童家庭环境对运动发育影响量表（FESMDUPC）的信效度，为测量家庭环境对儿童运动发育的影响因素提供有效可靠的工具。
本研究纳入苏州市15所幼儿园的1824名学龄前儿童，对FESMDUPC进行信效度研究。采用组内相关系数（ICC）、Cronbach α系数、条目水平内容效度指数（I-CVI）和验证性因子分析（CFA）评估重测信度、内部一致性信度、内容效度和结构效度。以修订后的环境测量观察法为标准，采用Spearman相关分析评估MABC的效标关联效度。
本研究显示所有条目的ICC均大于或接近0.9。总Cronbach α系数为0.875，删除每个条目后的Cronbach α系数为0.868 - 0.873。正式的效度和信度研究显示，23个条目的I-CVI为0.79 - 1.00，平均I-CVI为0.92。CFA模型结果显示，χ2 = 1077.5，df = 224，χ2/df = 4.810。模型其他指标的拟合优度如下：GFI（0.949）、AGF（0.937）、NFI（0.889）、CFI（0.896），均大于或接近0.9。RMSEA为0.046，表示模型的拟合优度可接受。因子载荷均大于0.3，具有统计学意义。然而，根据该模型，户外空间、室内空间和玩具之间的关系强度较高，因此对FESMDUPC进行了高阶CFA进一步分析。模型的拟合优度良好。因子载荷均大于0.3，具有统计学意义。结果显示，FESMDUPC总分与HOME量表的Spearman系数为0.476（各P < 0.001）。其中只有学习人员和活动多样性与玩具、父母教养方式的相关性相对较高。Spearman系数均大于0.3（各P < 0.001）。
上述结果表明，FESMDUPC的重测信度、内部一致性信度、内容效度和结构效度良好，满足基本的心理测量学要求。FESMDUPC可作为评估儿童运动发育的量化工具。
