Abstract

The 7-item Functionality Appreciation Scale (FAS; Alleva et al., 2017) measures an individual’s appreciation of their body for what it can do and is capable of doing (i.e., functionality appreciation). However, few studies have assessed the psychometric properties of the FAS in non-English speaking populations and in younger age groups. Here, we examined the psychometric properties of a novel Farsi translation of the FAS in Iranian adolescent girls and boys. A sample of 828 Iranian adolescents completed the FAS alongside the Rosenberg Self-Esteem Scale and the Beck Depression Inventory-II. Participants were randomly split into a first split-half for exploratory factor analysis (EFA) or a second split-half for confirmatory factor analysis (CFA). The EFA broadly supported a 1-dimensional model of FAS scores, although one item had low item-factor loadings. The CFA indicated that both the 6- and 7-item models had adequate fit. In further analyses, we found that the 7-item unidimensional model was invariant across gender and that higher FAS scores were significantly associated with higher self-esteem and lower depressive symptoms, indicative of convergent validity. These results provide evidence that the Farsi translation of the FAS is reliable and valid for use in Iranian adolescent girls and boys.
