This study aimed to develop and validate test-based physical literacy scales (PLSs) for primary school students across different grades.
Data were collected through a field survey conducted from June 1 to July 31, 2022, involving 3,275 primary school students from four provinces in China. The questionnaires assessed four domains: physical knowledge, physical competence, physical motivation, and physical behavior. The Rasch model was employed for psychometric analysis.
The variance explained by measures for the PLSs was 53.1%, 50.3%, and 54.7%, all exceeding the 50% threshold, confirming unidimensionality and robust internal consistency. This enabled effective differentiation among students with varying proficiency levels. The item-person map demonstrated optimal alignment between item difficulty and participant ability levels. Most items showed favorable fit statistics, with Infit mean square (MNSQ) and Outfit MNSQ values ranging between 0.5 and 1.5.
The PLSs demonstrate validity and reliability in measuring physical literacy among Chinese primary school students across four components: physical knowledge, physical competence, physical motivation, and physical behavior. The scales measure a unidimensional construct, supporting the use of summed total scores for assessment.
本研究旨在开发并验证适用于不同年级小学生的基于测试的身体素养量表（PLS）。
通过2022年6月1日至7月31日进行的实地调查收集数据，涉及中国四个省份的3275名小学生。问卷评估了四个领域：身体知识、身体能力、身体动机和身体行为。采用拉施模型进行心理测量分析。
PLS测量指标解释的方差分别为53.1%、50.3%和54.7%，均超过50%的阈值，证实了单维性和较强的内部一致性。这使得能够有效区分不同熟练程度的学生。项目-人员图显示项目难度与参与者能力水平之间具有最佳匹配。大多数项目显示出良好的拟合统计量，拟合均方（MNSQ）和外在MNSQ值在0.5至1.5之间。
PLS在测量中国小学生身体素养的四个组成部分（身体知识、身体能力、身体动机和身体行为）方面具有有效性和可靠性。这些量表测量的是一个单维结构，支持使用总分进行评估。
