The Functionality Appreciation Scale (FAS; Alleva et al., 2017) is a widely used instrument for the measurement of 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.

功能欣赏量表 (FAS; Alleva et al., 2017) 是一种广泛使用的工具，用于衡量个人对其身体可以做什么和能够做什么（即功能欣赏）。在这里，我们研究了 FAS 的意大利语新译本的心理测量特性。一个由 950 名意大利成年人组成的样本完成了 FAS，以及之前经过验证的身体形象测量（身体欣赏、身体自尊、身体监视）、饮食失调症状和心理健康（自尊、一般痛苦）。探索性和验证性因素分析支持 FAS 分数的一维模型，保留所有 7 个项目。分数实现了跨性别的标量不变性，潜在 FAS 分数的性别差异不显着。通过与所有其他结构的显着相关性，发现 FAS 分数具有足够的内部一致性、长达三周的重测信度以及收敛和标准相关的有效性。然而，增量有效性的证据很弱，并且可能反映了在这个国家背景下功能和身体欣赏之间的高度规则和概念相似性。总体而言，这些结果提供了强有力的证据，表明意大利 FAS 的分数在心理测量学上是有效的，这可能有助于未来发展干预措施，以促进意大利语样本中更积极的身体形象。
