Abstract

The Functionality Appreciation Scale (FAS; Alleva et al., 2017) 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). Here, we examined the psychometric properties of a novel Italian translation of the FAS. A sample of 950 Italian adults completed the FAS, as well as previously validated measures of body image (body appreciation, body esteem, body surveillance), disordered eating symptoms, and psychological well-being (self-esteem, general distress). Exploratory and confirmatory factor analyses supported a 1-dimensional model of FAS scores, with all 7 items retained. Scores achieved scalar invariance across gender, and the gender difference in latent FAS scores was not significant. FAS scores were found to have adequate internal consistency, test-retest reliability up to three weeks, and convergent and criterion-related validity through significant correlations with all additional constructs. However, evidence of incremental validity was weak, and likely reflected high nomological and conceptual similarity between functionality and body appreciation in this national context. Overall, these results provide strong evidence that scores on the Italian FAS are psychometrically valid, which may aid future development of interventions to promote more positive body image in Italian-speaking samples.
