Abstract

Abstract: The Body and Appearance Self-Conscious Emotions Scale (BASES; Castonguay et al., 2014 ) measures the individual’s shame, guilt, authentic and hubristic pride related to their body and appearance. The purpose of this study was to examine the psychometric properties of the Portuguese version of the BASES in a sample of adult individuals and the measurement invariance across gender. A sample of 506 participants completed the BASES and additional measures related to perfectionism and negative/positive affect. Confirmatory factor analyses supported the originally proposed four-factor structure of the BASES, with the best-fitted model dropping one item from the guilt factor. BASES showed adequate internal consistency, composite reliability, convergent validity and expected associations with perfectionism and affect measures. Scalar invariance was obtained across gender, with women showing significantly higher shame and guilt related to body and appearance than men. Our results support the use of the Portuguese BASES as a valid and reliable instrument to assess self-conscious emotions related to body and appearance.

葡萄牙语版身体与外貌自我意识情绪量表（BASES）的心理测量特性和测量不变性

摘要：身体和外貌自我意识情绪量表（BASES；Castonguay 等人，2014 年）测量个体与身体和外貌有关的羞耻感、内疚感、真实感和自负感。本研究旨在考察葡萄牙语版 BASES 在成人样本中的心理测量特性以及跨性别测量的不变性。506 名样本参与者完成了 BASES 以及与完美主义和消极/积极情绪相关的附加测量。确认性因子分析支持最初提出的 BASES 四因子结构，最佳拟合模型从内疚因子中删除了一个项目。BASES 显示出足够的内部一致性、复合信度、收敛效度以及与完美主义和情感测量的预期关联。该量表在不同性别间具有标度不变性，女性在身体和外貌方面表现出的羞耻感和内疚感明显高于男性。我们的研究结果支持将葡萄牙语 BASES 作为一种有效、可靠的工具，用于评估与身体和外貌有关的自我意识情绪。
