目的：本研究使用大量的项目对幼儿期运动能力的维度和同质性进行了研究。运动能力是指幼儿期掌握各种运动技能的能力。共1467名儿童采用4 ~ 6岁儿童运动能力测验对3-6岁儿童进行测试结果：采用部分信用模型和混合Rasch模型分析显示，儿童的认知结构为一维结构（CR = 1.964，p（CR）= .06; P-chi（2）= .227，p（p-chi 2）= .24）。由于阈值参数无序，排除了5个项目。这些项目有一个评分系统，计数成功的试验（0-2）的数量。结论：该研究显示项目和人的同质性在一个验证的运动评分，使用12个项目的MOT 4-6。因此，它提供了单一潜在结构的证据（即，运动能力），这是幼儿期运动技能表现的基础。此外，它表明，计数成功的实验次数可能不太适合作为运动能力评估的评分系统。目前的研究结果也支持使用验证的综合评分在运动评估。(C)2016爱思唯尔有限公司版权所有
Purpose: The present study investigated the dimensionality and homogeneity of motor competence, which is defined as the ability that underlies the performance of a wide variety of motor skills, in early childhood using a large set of items.Method: A total of 1467 children (aged 3-6 years) were measured with the Motor Proficiency Test for 4 to 6-Year-old Children (Motoriktest fur vier-bis sechsjahrige Kinder [MOT 4-6]), which consists of 17 items.Results: Analyses using the Partial Credit Model and mixed Rasch model revealed a one-dimensional structure (CR = 1.964, p(CR) = .06; P-chi(2) = .227, p(p-chi 2) = .24). Due to unordered threshold parameters, five items were excluded. These items have a scoring system that counts the amount of successful trials (0-2).Conclusion: The study shows item and person homogeneity within a validated motor score, using 12 items of the MOT 4-6. Thus, it provides evidence of a single latent construct (i.e., motor competence), which underlies the performance of motor skills in early childhood. Furthermore, it shows that counting the number of successful trails may be less suitable as a scoring system in motor competence assessment. Present findings also support the use of validated composite scores in motor assessment. (C) 2016 Elsevier Ltd. All rights reserved.
