AIMS
The EPInfant scale is a self-assessment for children that measures perceived exertion (PE) during physical exercise. This study aimed to translate the scale into Arabic (EPInfant-Ar) and test its psychometric properties.
METHODS
The revised version was tested for face and content validity. Oxygen saturation, heart rate (HR), and ratings of perceived exertion were measured during a 3-minute step test with a sample of 93 children. PE and HR were examined using the Pearson correlation coefficient () to assess the concurrent validity. Internal consistency and test-retest reliability were calculated using Cronbach's alpha (), intraclass correlation coefficient (ICC), and r coefficient. A minimum detectable change with 95% confidence interval (MDC) and percentage of change (MDC%) was also measured.
RESULTS
Content validity showed an excellent level of expert agreement. There was a moderate correlation between PE rated by the scale and HR ( = 0.47, < .001). The internal consistency and test-retest reliability were acceptable ( = 0.89; ICC 0.81; 95%Cl: 0.71-0.87, = 0.81) with low measurement error (MDC = 2.66 and MDC% = 61.10%).
CONCLUSIONS
The EPInfant-Ar scale was considered valid and reliable for assessing PE after physical exercises in typically developing children aged 6-16 years.
目的
EPInfant 量表是一种自我评估工具，用于测量儿童在体育锻炼时的感知用力（PE）。本研究旨在将该量表翻译成阿拉伯语（EPInfant-Ar）并测试其心理测量学特性。
方法
对修订后的量表进行了表面效度和内容效度检验。在一项 3 分钟的台阶测试中，对 93 名儿童的血氧饱和度、心率（HR）和感知用力等级进行了测量。使用 Pearson 相关系数（）来评估同时效度，PE 和 HR 之间的相关性。内部一致性和重测信度使用 Cronbach's alpha（）、组内相关系数（ICC）和 r 系数进行计算。还测量了具有 95%置信区间的最小可检测变化（MDC）和变化百分比（MDC%）。
结果
内容效度显示出专家高度一致的水平。量表评估的 PE 与 HR 之间存在中度相关性（ = 0.47， <.001）。内部一致性和重测信度是可接受的（ = 0.89；ICC 0.81；95%Cl：0.71-0.87， = 0.81），测量误差较低（MDC = 2.66 和 MDC% = 61.10%）。
结论
EPInfant-Ar 量表被认为在评估 6-16 岁正常发育儿童体育锻炼后的 PE 方面是有效和可靠的。
