Abstract

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.

德语翻译的功能欣赏量表（FAS）在德国成年人中的心理测量特征。

功能欣赏量表；Alleva等人，2017)是一种广泛使用的工具，用于衡量对身体能力的欣赏。然而，它还没有被翻译和验证，以便在讲德语的人群中使用。因此，本研究的目的是根据efa到cfa的方法验证FAS的德语翻译。在一个代表性样本（ = ）2570名参与者（1300名女性，1270名男性）和一个社区样本（ = ）466名参与者（371名女性，95名男性）中验证的结果表明，心理测量学具有良好的特性，并支持因子效度、男女之间的测量不变量、结构效度（通过与身体欣赏、身体不满、自尊、正念、直觉饮食、节制饮食、追求苗条和饮食失调风险的关联）。增量效度、内部一致性，初步支持德国FAS的2 ~ 4周重测信度。对被试在理解和主观反应困难方面的反馈进行定性分析，为FAS德文译文的效度提供了额外的支持。总的来说，FAS是一种适合测量德国成年人功能欣赏的工具。
