The Functionality Appreciation Scale (FAS; Alleva et al., 2017) is a widely used instrument to measure appreciation for what the body is able to do. However, it has yet to be translated and validated for use in German-speaking populations. The aim of the present work therefore was to validate a German translation of the FAS following the EFA-to-CFA approach. Results of this validation in a representative sample with N = 2570 participants (1300 women, 1270 men) and a community sample with N = 466 participants (371 women, 95 men) indicate good psychometric properties and support the factorial validity, measurement invariance across women and men, construct validity (through associations with body appreciation, body dissatisfaction, self-esteem, mindfulness, intuitive eating, restrained eating, drive for thinness, and risk for disordered eating), incremental validity, internal consistency and preliminarily support the 2-4 week test-retest reliability of the German FAS. A qualitative analysis of participant feedback on understanding and subjective response difficulty provided additional support for the validity of the German translation of the FAS. Overall, the FAS is a suitable instrument for measuring functionality appreciation in adults from Germany.
功能欣赏量表（FAS；Alleva等人，2017年）是一种广泛使用的工具，用于衡量对身体所能做之事的欣赏程度。然而，它尚未被翻译并验证是否适用于说德语的人群。因此，本研究的目的是遵循从探索性因素分析（EFA）到验证性因素分析（CFA）的方法，对FAS的德语翻译版本进行验证。在一个有N = 2570名参与者（1300名女性，1270名男性）的代表性样本和一个有N = 466名参与者（371名女性，95名男性）的社区样本中进行验证的结果表明，该量表具有良好的心理测量特性，并支持其因素效度、男女之间的测量不变性、结构效度（通过与身体欣赏、身体不满、自尊、正念、直觉性饮食、克制性饮食、瘦身驱动力和饮食失调风险的关联）、增量效度、内部一致性，并且初步支持德语版FAS的2至4周重测信度。对参与者关于理解和主观反应难度的反馈进行的定性分析为FAS德语翻译版本的效度提供了额外支持。总体而言，FAS是一种适用于测量德国成年人功能欣赏程度的工具。
