The increase of cross-cultural studies and intervention programs, based on the self-determination theory, highlights the urge for validated scales to ensure high-quality research, particularly in the domain of physical education. The present study aimed at evaluating the psychometric properties and measurement invariance of the revised Perceived Locus of Causality Scale (PLOC-R) in physical education and the Behavioral Regulation in Exercise Questionnaire (BREQ-II) during leisure-time translations from English into German and French among youth. Data obtained from 1808 Luxemburgish students supported the five-factor structure of the translated PLOC-R as well as for the BREQ-II and showed good internal reliability as well as concurrent, discriminant, and nomological validity. Measurement invariance analyses across the two languages revealed configural, metric, and partial scalar invariance for both questionnaires. The findings provide promising evidence for the reliability and validity of the translated PLOC-R and BREQ-II and support their use in cross-cultural and physical activity–related motivational research.

基于自决理论的跨文化研究和干预计划的增加，突显了对经过验证的量表的需求，以确保高质量的研究，特别是在体育领域。本研究旨在评估在休闲英语翻译成德语和德语的过程中修订的体育因果量表（PLOC-R）和运动问卷中的行为调节（BREQ-II）的心理计量学特性和测量不变性。青年时期的法国人。从1808年卢森堡学生那里获得的数据支持翻译后的PLOC-R以及BREQ-II的五因子结构，并显示出良好的内部可靠性以及并发性，判别性和法理有效性。跨两种语言的度量不变性分析显示了两种问卷的配置，度量和部分标量不变性。这些发现为翻译后的PLOC-R和BREQ-II的可靠性和有效性提供了有希望的证据，并支持它们在跨文化和体育活动相关的动机研究中的使用。
