This study aimed to assess the psychometric properties of the Lithuanian translation of the Functionality Appreciation Scale (FAS). A sample (n = 759) of adults (424 women and 335 men; mean age 23.2 ± 7.1 and age range 18-44 years) participated in the cross-sectional study. Body functionality appreciation, body appreciation, self-esteem, disordered eating and physical activity habits were assessed. Exploratory factor analysis (EFA; n = 379) identified a unidimensional factor structure of FAS, supported by findings in a second split-subsample using confirmatory factor analysis (CFA, n = 380). FAS scores were invariant across gender groups. No mean score differences were observed between genders. Composite reliability of FAS was established in women (ω = 0.94, 95% CI = 0.92, 0.95) and men (ω = 0.92, 95% CI = 0.90, 0.94). Positive associations of FAS with body appreciation, self-esteem and physical activity habits and negative relationships with disordered eating and BMI (in women) confirmed construct validity. FAS predicted self-esteem over and above the variance accounted for by other study measures. The Lithuanian version of FAS is a psychometrically sound measure of body functionality appreciation. FAS might contribute to a comprehensive assessment of positive body image and can be used in various interventions.
本研究旨在评估立陶宛语版功能欣赏量表（FAS）的心理测量特性。一个由成年人组成的样本（n = 759）（424名女性和335名男性；平均年龄23.2 ± 7.1岁，年龄范围18 - 44岁）参与了这项横断面研究。对身体功能欣赏、身体欣赏、自尊、饮食失调和体育活动习惯进行了评估。探索性因素分析（EFA；n = 379）确定了FAS的单维因素结构，在第二个分割子样本中使用验证性因素分析（CFA，n = 380）的结果支持了这一结构。FAS得分在不同性别组中具有不变性。未观察到性别之间的平均得分差异。在女性（ω = 0.94，95%CI = 0.92，0.95）和男性（ω = 0.92，95%CI = 0.90，0.94）中建立了FAS的组合信度。FAS与身体欣赏、自尊和体育活动习惯呈正相关，与饮食失调和BMI（女性）呈负相关，证实了结构效度。FAS预测自尊的能力超过了其他研究测量所解释的方差。立陶宛语版的FAS是一种心理测量学上可靠的身体功能欣赏测量工具。FAS可能有助于对积极身体形象进行全面评估，并可用于各种干预措施。
