本研究旨在编制足球守门员动作反应敏捷性测验，并检验其信度与效度。我们设计了一个五分支的星形课程，在反应条件下进行潜水和接球动作。在设置中，起始球门线设置在分支的顶部，并且距离星形设置的中心3.5 m。内容效度由六位专家进行评估，并计算项目内容效度指数（I-CVI）。33名男性GK进行了两次测试试验。G-RAT的一个测试试验包括三个穿梭从开始的球门线，潜水和接球。在被动条件下，指导运动员在身体躯干距离起始球门线1.5米时应向哪个球的方向俯冲。GK分为规则（R）和非规则（NR）组。采用组内相关系数（ICC）和受试者工作特征（ROC）曲线分析方法，评价量表的信度和收敛效度。I-CVI为0.83，大于可接受水平0.78。ICC值为0.94（p < 0.01; 95%置信区间（95%CI），0.88-0.97）。GK在R组和NR组中分别完成了14.3 ± 0.7和15.3 ± 1.0 s（p < 0.01; Cohen's d = 0.89）。G-RAT的曲线下面积为0.80（95%CI，0.64-0.96）。这些结果表明，在反应条件下的GK特定的敏捷性测试将有足够的信度和内容和收敛效度在大学年龄的GK。
The purpose of this study was to develop a reactive agility test with soccer goalkeeper (GK)-specific movements (G-RAT) and to examine the reliability and validity of college-aged GKs. We designed a five-branch star-shaped course with diving and ball-catching movements under reactive conditions. In the setup, a start–goal line was set on the top of a branch and 3.5 m away from the center of the star-shaped setting. Content validity was assessed by six experts, and the item-content validity index (I-CVI) was calculated. Thirty-three male GKs performed the test trial twice. One test trial of G-RAT consists of three shuttles from the start–goal line to diving and ball-catching. For the reactive condition, GKs were instructed on which ball directions should dive when their body trunk reached 1.5 m away from the start–goal line. GKs were classified into regular (R) or non-regular (NR) groups. The intraclass correlation coefficient (ICC) and the receiver operating characteristic (ROC) curve analyses were used to assess the reliability and predictive power as convergent validity. The I-CVI was 0.83, which was greater than the acceptable level of 0.78. The ICC value was 0.94 (p < 0.01; 95% confidence interval (95%CI), 0.88–0.97). The GKs completed the test 14.3 ± 0.7 and 15.3 ± 1.0 s in the R and NR group (p < 0.01; Cohen’s d = 0.89), respectively. The area under the curves of G-RAT was 0.80 (95%CI, 0.64–0.96). These results show that a GK-specific agility test under reactive conditions would have sufficient reliability and both content and convergent validity in college-aged GKs.
