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.

期刊介绍： Body Image is an international, peer-reviewed journal that publishes high-quality, scientific articles on body image and human physical appearance. Body Image is a multi-faceted concept that refers to persons perceptions and attitudes about their own body, particularly but not exclusively its appearance. The journal invites contributions from a broad range of disciplines-psychological science, other social and behavioral sciences, and medical and health sciences. The journal publishes original research articles, brief research reports, theoretical and review papers, and science-based practitioner reports of interest. Dissertation abstracts are also published online, and the journal gives an annual award for the best doctoral dissertation in this field.
