This study aimed to translate and adapt the psychometric properties of the Behavioural Regulation in Active Commuting to School (BR-ACS) questionnaire to young Portuguese students. This study had two stages: (1) translation and adaptation of the questionnaire; (2) evaluation of the psychometric properties. A sample of 338 participants (212 female, 126 male) aged 11 to 19 years (M = 15.6 ± 2.1) from 31 cities and Madeira island participated in this study. The confirmatory factor analysis suggested an acceptable fit to the data for the first-order and third-order measurement models. The composite reliability values ranged from 0.71 (identified regulation) to 0.90 (integrated regulation), demonstrating internal consistency. The AVE values ranged from 0.40 (amotivation) to 0.69 (integrated regulation), demonstrating an acceptable convergent validity for all constructs. The model estimation had an acceptable fit, with values akin to those of the first-order tested model. Finally, the results of the multigroup analysis for the successive restricted models (CFI < 0.010 and RMSEA < 0.015) point out that the null hypothesis of factor invariance between gender cannot be rejected. The psychometric properties demonstrates the suitability of this questionnaire among Portuguese youths aged 11 to 19. This questionnaire will help understand the motivation aspects that underpin active commuting to school and consequently help to increase physical activity among Portuguese adolescents.
本研究旨在将《步行上下学行为调节问卷》（BR-ACS）的心理测量学特性翻译并改编，以适用于葡萄牙年轻学生。本研究分两个阶段进行：（1）问卷的翻译与改编；（2）心理测量学特性评估。来自31个城市和马德拉岛的338名年龄在11至19岁（M = 15.6 ± 2.1）的参与者（212名女性，126名男性）参与了本研究。验证性因素分析表明，一阶和三阶测量模型与数据拟合良好。组合信度值范围从0.71（认同调节）到0.90（整合调节），表明具有内部一致性。AVE值范围从0.40（无动机）到0.69（整合调节），表明所有构念都具有可接受的聚合效度。模型估计拟合良好，其值与一阶测试模型相近。最后，连续受限模型的多组分析结果（CFI < 0.010且RMSEA < 0.015）指出，性别间因素不变性的零假设不能被拒绝。心理测量学特性表明该问卷适用于11至19岁的葡萄牙青少年。这份问卷将有助于理解支撑步行上下学的动机因素，从而有助于增加葡萄牙青少年的身体活动。
