Active commuting to and from school (ACS) is a strategy to enhance physical activity levels in youths. To promote ACS, it is important to understand the factors that lead to this behaviour. With this in mind, an adaptation of the Basic Psychological Needs in Exercise Scale for ACS was developed, named the Basic Psychological Need Satisfaction in Active Commuting to and from School (BPNS-ACS) scale. This study aimed to translate and evaluate the psychometric properties of the BPNS-ACS scale in young Portuguese students. A cross-sectional study was designed. A total of 338 students (212 girls, 126 boys), aged between 11 and 19 years old from 31 Portuguese cities participated in this study. To provide validity evidence based on the questionnaire's internal structure, confirmatory factor analyses were performed to test the three dimensions of the BNPS-ACS scale. The results of the confirmatory factor analysis indicated an acceptable fit to the data. The internal consistency of the measures was accepted as the composite reliability values ranged from 0.78 to 0.94. The evaluation of psychometric properties provided evidence of the adequacy of this questionnaire among Portuguese youth aged 11 to 19 years old.
积极往返学校（ACS）是提高青少年身体活动水平的一种策略。为了促进 ACS，了解导致这种行为的因素很重要。考虑到这一点，对 ACS 的基本心理需求量表进行了改编，命名为积极往返学校的基本心理需求满足度（BPNS-ACS）量表。本研究旨在翻译和评估该量表在年轻葡萄牙学生中的心理测量特性。设计了一项横断面研究。共有 338 名学生（212 名女生，126 名男生）参加了这项研究，年龄在 11 至 19 岁之间，来自葡萄牙 31 个城市。为了根据问卷的内部结构提供有效性证据，进行了验证性因素分析，以检验 BNPS-ACS 量表的三个维度。验证性因素分析的结果表明，数据的拟合度可以接受。测量的内部一致性被接受，因为综合可靠性值在 0.78 到 0.94 之间。心理测量特性的评估为 11 至 19 岁的葡萄牙青少年使用该问卷提供了充分性的证据。
