To examine the validity and reliability of the Simple Motor Competence-check for Kids (SMC-Kids), which was developed to assess motor development in preschool children.
A cross-sectional and repeated-measures design.
To assess validity, 71 children aged 4-6 years completed the Test of Gross Motor Development-3 (TGMD-3) and SMC-Kids (10 m shuttle run and paper ball throw). For inter-rater reliability, 91 children aged 3-6 years performed the SMC-Kids test, twice, by two different raters. To evaluate intra-rater reliability and quantify improvements beyond measurement error, 53 participants were reassessed by the same rater 7-10 days later.
Spearman's rho between the 10 m shuttle run and the TGMD-3 locomotor score was -0.51 (95 % CI: -0.31, -0.66), and between the paper ball throw and TGMD-3 ball skill score was 0.80 (95 % CI: 0.70, 0.87). Confirmatory factor analysis showed strong associations of the 10 m shuttle run and paper ball throw with latent variables of locomotor and object control skills, with factor loadings of -0.97 and 0.88, respectively. Both tests showed good-to-excellent inter-rater (ICC = 0.898-0.96) and intra-rater reliabilities (ICC = 0.882-0.974). The smallest worthwhile changes were 0.25 s for the 10 m shuttle run and 0.42 m for the paper ball throw, with double coefficients of variation of 0.46 s and 0.99 m, and MDC 95 of 0.82 s and 1.52 m, respectively.
SMC-Kids is a simple tool to quickly measure preschooler locomotor and object control skills without the need for special equipment or large spaces.
检验儿童简单运动能力检查表（SMC-Kids）的有效性和可靠性，该检查表旨在评估学龄前儿童的运动发育情况。
横断面和重复测量设计。
为评估有效性，71名4至6岁儿童完成了粗大运动发育测试-3（TGMD-3）和SMC-Kids（10米往返跑和纸球投掷）。为评估评分者间信度，91名3至6岁儿童由两名不同评分者进行了两次SMC-Kids测试。为评估评分者内信度并量化测量误差之外的改善情况，53名参与者在7至10天后由同一名评分者重新评估。
10米往返跑与TGMD-3运动能力得分之间的Spearman相关系数为-0.51（95%CI：-0.31，-0.66），纸球投掷与TGMD-3球类技能得分之间的相关系数为0.80（95%CI：0.70，0.87）。验证性因素分析表明，10米往返跑和纸球投掷与运动能力和物体控制技能的潜在变量有很强的关联，因素负荷分别为-0.97和0.88。两项测试均显示出良好至优秀的评分者间信度（ICC = 0.898 - 0.96）和评分者内信度（ICC = 0.882 - 0.974）。10米往返跑的最小有意义变化为0.25秒，纸球投掷为0.42米，双变异系数分别为0.46秒和0.99米，95%最小可检测变化分别为0.82秒和1.52米。
SMC-Kids是一种简单的工具，无需特殊设备或大空间即可快速测量学龄前儿童的运动能力和物体控制技能。
