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). Here, we examined the psychometric properties of a novel Arabic translation of the FAS. A sample of 826 Lebanese adults completed the FAS, as well as previously validated measures of body appreciation, disordered eating attitudes, orthorexia, 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 women reporting significantly greater functionality appreciation than men. FAS scores were found to have adequate composite reliability and adequate patterns of convergent and criterion-related validity. Additionally, 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 Arabic FAS is a psychometrically valid tool for the assessment of functionality appreciation. The availability of the Arabic FAS should facilitate improved understanding of the effectiveness of existing interventions designed to promote greater physical activity in the Lebanese context.

功能欣赏量表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的欣赏（即功能欣赏）。在这里，我们检查了新的 FAS 阿拉伯语翻译的心理测量学特性。826 名黎巴嫩成年人的样本完成了 FAS，以及先前验证的身体欣赏、饮食态度紊乱、食欲不振和自尊的测量。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，女性报告的功能欣赏明显高于男性。发现 FAS 分数具有足够的综合信度和足够的收敛效度和标准相关效度。此外，一旦考虑了所有其他变量的影响，功能鉴赏可以预测自尊，从而支持增量有效性。全面的，这些结果表明，阿拉伯语 FAS 是评估功能欣赏的心理测量有效工具。阿拉伯语 FAS 的可用性应有助于更好地理解现有干预措施的有效性，这些干预措施旨在促进在黎巴嫩开展更多的身体活动。
