The aim of this study was to examine the reliability and validity of the Spanish Perceived Physical Literacy Instrument (S-PPLI) questionnaire in Spanish adolescents.
The participants of this study were 360 Spanish adolescents (aged 12-17 years) from three secondary schools in the Region of Murcia (Spain). A cultural adaptation process of the original version of the PPLI questionnaire was developed. Confirmatory factor analysis was applied to test the three-factor structure of physical literacy. Intraclass correlation coefficients were computed to estimate the test-retest concordance.
Using a confirmatory factor analysis, the factor loading of all items above the standard of 0.40 ranged from 0.53 to 0.77, suggesting that the observed variables sufficiently represented the latent variables. Analyses for convergent validity showed average variance extracted values that ranged from 0.40 to 0.52 and composite reliability values higher than 0.60. All the correlations were below the recommended cutoff point of 0.85, which indicated that the three physical literacy factors achieved adequate discriminant validity. Intraclass correlation coefficients ranged from 0.62 to 0.79 ( < 0.001 for all items), which indicated moderate/good reliability.
Our results suggest that the S-PPLI is a valid and reliable measure of physical literacy among Spanish adolescents.
本研究旨在检验西班牙青少年身体素养感知量表（S-PPLI）问卷在西班牙青少年中的信度和效度。
本研究的参与者为来自西班牙穆尔西亚地区三所中学的360名西班牙青少年（年龄在12 - 17岁之间）。对PPLI问卷的原始版本进行了文化适应性调整。应用验证性因素分析来检验身体素养的三因素结构。计算组内相关系数以估计重测一致性。
通过验证性因素分析，所有项目的因素负荷均高于0.40的标准，范围在0.53至0.77之间，这表明观测变量充分代表了潜在变量。收敛效度分析显示，平均方差抽取值范围在0.40至0.52之间，组合信度值高于0.60。所有相关性均低于推荐的截断点0.85，这表明三个身体素养因素具有足够的区分效度。组内相关系数范围在0.62至0.79之间（所有项目的p < 0.001），表明信度为中等/良好。
我们的结果表明，S-PPLI是西班牙青少年身体素养的有效且可靠的测量工具。
