The purpose of this study was to evaluate the content and construct validity and between-sessions reliability of four agility tests requiring ball dribbling in football players with cerebral palsy (CP) with implications for classification and training. A sample of 35 football players with CP from three different countries took part in the study. They performed four tests in two sessions 72 h apart: i) 20 m in a straight line, ii) forward slalom with short changes of direction, iii) forward slalom with wide changes of direction and iv) square course. The Kappa coefficient was used to test content validity, obtaining moderate to almost perfect agreement results. Construct validity was also demonstrated with very large to almost perfect correlations between tests and sessions. Good reliability was found using intra-class coefficients (>0.86), standard error of measurement (<10.8%) and Cronbach´s alpha (>0.86). The comparisons between CP profiles (i.e. sport classes) demonstrated that those with mild impairment performed faster, and those with impairment of ataxia and dyskinesia performed worse. The four tests could have applications in classification, but may also be applied by the CP football coaches to improve athlete agility and football skills.
本研究旨在评估四项需要在脑瘫（CP）足球运动员中进行运球的敏捷性测试的内容效度、结构效度和组内信度，以对分类和训练提供参考。来自三个不同国家的35名患有CP的足球运动员参与了这项研究。他们在相隔72小时的两个时段内进行了四项测试：i）直线20米跑，ii）方向变化较小的向前障碍跑，iii）方向变化较大的向前障碍跑，以及iv）方形路线跑。使用Kappa系数来测试内容效度，获得了中度到几乎完美的一致性结果。测试与时段之间还呈现出非常高到几乎完美的相关性，证明了结构效度。使用组内相关系数（>0.86）、测量标准误差（<10.8%）和克朗巴赫α系数（>0.86）发现了良好的信度。CP特征（即运动类别）之间的比较表明，轻度受损者表现更快，而患有共济失调和运动障碍的受损者表现更差。这四项测试可用于分类，但CP足球教练也可应用它们来提高运动员的敏捷性和足球技能。
