Active travel (cycling or walking to school) can be a substantial part of adolescents' daily physical activity. Research on transport activities primarily relies on self-reported indices of travel mode and travel time. However, many researchers do not report the psychometric properties of their instruments. The Health Behavior in School-aged Children (HBSC) questionnaire is a commonly used instrument, but the items in this questionnaire on travel habits have not yet been validated. The present study was conducted to investigate the convergent validity and agreement between the HBSC items and a travel diary on (1) transport mode to and from school and (2) travel time to school.
The study sample consisted of 50 participants in the 9th grade (15 ± 0.3 years, 62% girls) from seven Norwegian schools. Outcome variables included transport mode and travel time derived from the HBSC items and a five-day travel diary. Convergent validity was assessed by evaluating Cohen's kappa for travel mode and the correlation coefficient (Spearman Rho) for travel time. Simple agreement calculations between the two measurement methods were also conducted.
The association between the HBSC questionnaire and the diary for travel mode to and from school was κ = 0.63 ( < 0.001) and κ = 0.77 ( < 0.001), respectively. The total agreement between the HBSC questionnaire and the diary for was 78%. However, the agreement was higher for walking (88%) and cycling (91%) than for motorized transport (67%). For travel time, the Spearman correlation coefficient was ρ = 0.60 ( < 0.001) between the HBSC questionnaire and the diary. The total agreement on travel time was 67%; however, active commuters (86%) seemed to more accurately estimated travel time than motorized commuters (55%).
Although the overall agreement between the HBSC questionnaire and the diary for mode of transport was 78%, the HBSC questionnaire may underestimate the prevalence of motorized transport compared to walking and cycling.

主动出行（骑自行车或步行上学）可能是青少年日常身体活动的重要组成部分。关于交通活动的研究主要依赖于自我报告的出行方式和出行时间指标。然而，许多研究人员并未报告其工具的心理测量特性。学龄儿童健康行为（HBSC）问卷是一种常用工具，但该问卷中关于出行习惯的项目尚未经过验证。本研究旨在调查HBSC项目与出行日记在以下方面的收敛效度和一致性：（1）往返学校的交通方式；（2）上学的出行时间。
研究样本包括来自挪威七所学校的50名九年级学生（15±0.3岁，62%为女生）。结果变量包括从HBSC项目和为期五天的出行日记中得出的交通方式和出行时间。通过评估出行方式的科恩kappa系数和出行时间的相关系数（斯皮尔曼等级相关系数）来评估收敛效度。还对两种测量方法之间进行了简单一致性计算。
HBSC问卷与往返学校出行方式的日记之间的关联分别为κ = 0.63（P < 0.001）和κ = 0.77（P < 0.001）。HBSC问卷与日记之间的总体一致性为78%。然而，步行（88%）和骑自行车（91%）的一致性高于机动交通（67%）。对于出行时间，HBSC问卷与日记之间的斯皮尔曼相关系数为ρ = 0.60（P < 0.001）。出行时间的总体一致性为67%；然而，主动通勤者（86%）似乎比机动通勤者（55%）更能准确估计出行时间。
尽管HBSC问卷与交通方式日记之间的总体一致性为78%，但与步行和骑自行车相比，HBSC问卷可能低估了机动交通的普及率。
