Psychometric properties of a Greek translation of the Functionality Appreciation Scale (FAS) in adults from the Republic of Cyprus

Abstract

The Functionality Appreciation Scale is a widely used instrument for the measurement of an individual's appreciation of their body for what it can do and is capable of doing (i.e., functionality appreciation). In the present study, we examined the psychometric properties of a novel Greek translation of the FAS in Cypriot adults. A total of 448 women and 345 men from the Republic of Cyprus completed the FAS, as well as validated measures of body appreciation, appearance evaluation, and symptoms of disordered eating, and self-esteem. Exploratory and confirmatory factor analyses supported a unidimensional model of FAS scores, with all 7 items retained. Scores achieved scalar invariance across gender, with the gender difference in FAS scores not reaching significance. FAS scores were also found to have adequate composite reliability and convergent (significant associations with body appreciation, appearance evaluation, and symptoms of disordered eating) and concurrent validity (significant associations with self-esteem). Finally, functionality appreciation predicted self-esteem once the effects of all other variables had been accounted for, supporting incremental validity. Overall, these results suggest that the Greek FAS is a psychometrically valid tool for the assessment of functionality appreciation in adults from Cyprus.
