Godin休闲时间锻炼问卷评估成年人自我报告的体力活动(PA)，后来针对儿童进行了修改。然而，修订后的版本(戈丁-儿童问卷)尚未在青少年中得到验证。本研究对Godin-Child问卷在青少年中的结构效度和重测信度进行了评价。研究参与者为六年级学生(年龄为11.06±0.436岁；48%为男性，48%为拉丁裔)，在两个时间点(秋季和春季：n=139)进行评估。首先，这项研究确定了青少年是否根据青少年在中强度和大强度运动任务中的感知劳力(RPE)评级准确地报告了运动强度。第二，使用Actigraph®加速度计获得的PA客观评估与Godin-Child问卷上的PA自我报告相关。第三，重测相关评价了Godin-Child问卷的信度。最后，访谈探讨了参与者对戈丁-儿童问卷的解释。RPE表明，青少年通常可以准确地感知运动强度，性别之间没有显著差异。在秋季(r=0.22，P<；0.05)和春季(r=0.24，P<；0.05)，Godin-Child问卷与Actigraph®之间的相关性很弱，而男性(P<；0.05)在这两个时间段都有显著的相关性。重测相关性是可以接受的(秋季-春季r=.68；P<；.001)，在女性和男性之间也同样强。采访显示，一些受访者忽视了书面说明。戈丁-儿童问卷可能是一种有用的自我报告的体力活动的评估指标，用于比较不同青少年群体的活动水平，但对于评估个人层面的体力活动可能不太准确。
The Godin Leisure-Time Exercise Questionnaire assesses self-reported physical activity (PA) among adults, and was later modified for children. However, the modified version (Godin-Child Questionnaire) has not been validated among adolescents. This study evaluates the construct validity and test-retest reliability of the Godin-Child Questionnaire among adolescents. The study participants, sixth graders (age M= 11.06 ± 0.436; 48% males, 48% Latino), were assessed at 2 time points (fall and spring: N= 139). First, the study determined whether adolescents accurately reported exercise intensity based on adolescents' ratings of perceived exertion (RPE) during moderate- and hard-intensity exercise tasks. Second, objective assessments of PA obtained using the Actigraph® accelerometer were correlated with PA self-reported on the Godin-Child Questionnaire. Third, test-retest correlations evaluated the Godin-Child Questionnaire for its reliability. Finally, interviews explored participants' interpretations of the Godin-Child Questionnaire. RPEs suggested that adolescents generally perceived exercise intensity accurately, with no significant differences between genders. There was a weak correlation between the Godin-Child Questionnaire and the Actigraph® during fall (r=.22, P< .05) and spring (r=.24, P<.05), with a significant correlation for males (P<.05) at both time periods. Test-retest correlations were acceptable (fall-spring r=.68; P<.001) and were equally strong among females and males. Interviews revealed that some respondents overlooked written directions. The Godin-Child Questionnaire may be a useful evaluative measure of self-reported physical activity for comparing activity levels across groups of adolescents, but may be less accurate for assessing physical activity on an individual level.
