Body appreciation is a key characteristic, and the most common operationalization, of positive body image. Positive body image is often measured using the Body Appreciation Scale-2 (BAS-2; Tylka & Wood-Barcalow, 2015a), which has demonstrated good psychometric properties in adult samples. The purpose of this study is to extend the validation of the BAS-2 to late adulthood facilitating future research with this population. A total of 202 male and female participants (aged 65-91 years) completed the Portuguese version of the BAS-2, along with other body image-related instruments and measures of self-esteem and intuitive eating. Confirmatory factor analysis supported the one-factor model and demonstrated sex invariance. There were no significant sex differences in BAS-2 scores. The BAS-2 had satisfactory convergent, discriminant, and incremental validity. Internal consistency and test-retest stability estimates were adequate. The BAS-2 will likely meet the needs of researchers interested in exploring body appreciation among elderly people.
身体欣赏是积极身体形象的一个关键特征,也是最常见的操作化表现。积极的身体形象通常使用身体欣赏量表-2(BAS-2;Tylka 和 Wood-Barcalow,2015a)来衡量,该量表在成年样本中已证明具有良好的心理测量特性。本研究的目的是将 BAS-2 扩展到老年期,为该人群的未来研究提供便利。共有 202 名男性和女性参与者(年龄 65-91 岁)完成了 BAS-2 的葡萄牙语版本,以及其他与身体形象相关的工具,以及自尊和直觉饮食的测量。验证性因素分析支持单因素模型,并证明了性别不变性。BAS-2 得分在性别上没有显著差异。BAS-2 具有令人满意的聚合、区分和增量有效性。内部一致性和重测信度估计值是足够的。BAS-2 可能满足了研究人员对探索老年人身体欣赏的兴趣。
