BACKGROUND
Despite the growing interest in active (ie, nonmotorized) travel to and from school, few studies have explored the measurement properties to assess active travel. We evaluated the criterion validity and test-retest reliability of a questionnaire with a sample of young schoolchildren to assess travel to and from school, including mode, travel companion, and destination after school.
METHODS
To assess test-retest reliability, 54 children age 8 to 11 years completed a travel survey on 2 consecutive school days. To assess criterion validity, 28 children age 8 to 10 years and their parents completed a travel survey on 5 consecutive weekdays.
RESULTS
Test-retest reliability of all questions indicated substantial agreement. The questions on mode of transport, where you will go after school, and how you will get there also displayed substantial agreement between parental and child reports.
CONCLUSIONS
For this population, a questionnaire completed by school-age children to assess travel to and from school, including mode, travel companion, and destination after school, was reliably collected and indicated validity for most items when compared with parental reports.
背景
尽管人们对往返学校的主动出行（即非机动出行）的兴趣日益浓厚，但很少有研究探讨评估主动出行的测量属性。我们以一群小学生为样本，评估了一份问卷的标准效度和重测信度，该问卷用于评估往返学校的出行情况，包括出行方式、出行同伴以及放学后的目的地。
方法
为评估重测信度，54名8至11岁的儿童在连续两个上学日完成了一项出行调查。为评估标准效度，28名8至10岁的儿童及其父母在连续五个工作日完成了一项出行调查。
结果
所有问题的重测信度显示出高度一致性。关于交通方式、放学后去向以及如何到达目的地的问题，父母和孩子的报告之间也显示出高度一致性。
结论
对于这一群体而言，由学龄儿童填写的用于评估往返学校出行情况（包括出行方式、出行同伴以及放学后目的地）的问卷，收集结果可靠，与父母报告相比，大多数项目显示出效度。
