The purpose of this study was to assess the interrater and test-retest reliability and the concurrent validity of the modified timed up and go test for preschoolers. As such, we aim to determine the most suited outcome of the modified timed up and go test: the best or the average performance. Thirty-two children (age 3-5) performed three timed up and go test trials as fast as possible on two separate occasions. During the first session, two researchers recorded the time to perform the task simultaneously. For reliability analyses, intra-class correlation coefficients (ICCs) and the minimal detectable change were determined. A Pearson correlation coefficient was calculated to determine concurrent validity between the timed up and go test and the balance subscale of the Movement Assessment Battery for Children, 2nd edition. Interrater (ICC > 0.97) and test-retest (ICC > 0.75) reliability were good both for the average and the best timed up and go test performance. A minimal detectable change of 1.86 s was found for the best performance, and 2.30 s for the average performance. Only the best timed up and go test performance correlated significantly with the balance subscale of the Movement Assessment Battery for Children, 2nd edition, though fair (r = -0.347, p = 0.007).Conclusion: The modified timed up and go test for preschoolers using the best performance is reliable and recommended to reduce standard and measurement error. What is Known: • A large variety of timed up and go test protocols is available for children • The protocols differ in the instructions on walking speed (self-selected/fastest), the use of an extra motivation (e.g., touch a star on the wall) and the applied outcome (average/best performance) What is New: • The best timed up and go test performance induces more consistent test results between raters and sessions and also less standard and measurement error in 3- to 5-year-old children • The best timed up and go test performance should be preferred over the average performance to achieve both reliable and valid test results in 3- to 5-year-old children.
本研究的目的是评估改良版学前儿童计时起立行走测试的评分者间信度、重测信度以及同时效度。因此，我们旨在确定改良版计时起立行走测试最合适的结果：最佳表现还是平均表现。32名3至5岁儿童在两个不同场合尽可能快地进行了三次计时起立行走测试。在第一次测试中，两名研究人员同时记录完成任务的时间。为进行信度分析，确定了组内相关系数（ICC）和最小可检测变化。计算了Pearson相关系数，以确定计时起立行走测试与《儿童运动评估量表》第二版平衡子量表之间的同时效度。评分者间信度（ICC>0.97）和重测信度（ICC>0.75）对于最佳和平均计时起立行走测试表现均良好。最佳表现的最小可检测变化为1.86秒，平均表现为2.30秒。尽管相关性一般（r=-0.347，p=0.007），但只有最佳计时起立行走测试表现与《儿童运动评估量表》第二版平衡子量表显著相关。结论：使用最佳表现的改良版学前儿童计时起立行走测试是可靠的，建议采用以减少标准误差和测量误差。已知信息：• 有多种适用于儿童的计时起立行走测试方案 • 这些方案在行走速度指令（自选/最快）、是否使用额外激励（如触摸墙上的星星）以及应用的结果（平均/最佳表现）方面存在差异 新发现：• 最佳计时起立行走测试表现能在评分者和测试环节之间产生更一致的测试结果，并且在3至5岁儿童中也能减少标准误差和测量误差 • 为在3至5岁儿童中获得可靠且有效的测试结果，应优先选择最佳计时起立行走测试表现而非平均表现。
