Abstract

Among gender-expansive individuals and transgender men, body appreciation can play a protective role against minority stressors and is associated with gender euphoria. The Body Appreciation Scale (BAS-2; Tylka & Wood-Barcalow, 2015) is a leading measure of body appreciation that has been mainly validated in cisgender and mixed-gender samples; however, it has not been validated among Brazilian gender-expansive individuals and transgender men. Therefore, we evaluated the psychometric properties of the BAS-2 among adult Brazilian gender-expansive individuals and transgender men. Participants (158 gender-expansive individuals and 138 transgender men) were recruited through social media in Brazil. Confirmatory Factor Analysis (CFA) supported the original 10-item, unidimensional solution. Multigroup CFA showed configural, metric, and scalar invariance of the BAS-2 between gender-expansive individuals and transgender men. Moreover, the BAS-2 demonstrated significant negative associations, ranging from small to large, with self-objectification, drive for muscularity, and appearance-ideal internalization. We also found good internal consistency and test-retest reliability of the measure. Taken together, our results support the psychometric properties of the BAS-2 among Brazilian gender-expansive individuals and transgender men. The present work offers a valuable contribution towards better understanding facets of positive body image across gender-expansive and transgender populations.

巴西性别开放者和变性男子身体鉴赏量表 - 2 的因子结构和测量不变性。

在性别开放的个体和变性男性中，身体鉴赏可以对少数群体的压力起到保护作用，并与性别欣快感相关联。身体鉴赏量表（BAS-2；Tylka & Wood-Barcalow，2015 年）是身体鉴赏的主要测量方法，主要在顺性和混性样本中得到验证；但是，该量表尚未在巴西的性别开放者和变性男性中得到验证。因此，我们在巴西成年性别开放者和变性男性中对 BAS-2 的心理测量特性进行了评估。我们通过社交媒体在巴西招募了参与者（158 名性别开放者和 138 名变性男性）。确认性因子分析（CFA）支持最初的 10 项单维解决方案。多组 CFA 显示，BAS-2 在性别开放者和变性男性之间具有构型、度量和标度不变性。此外，BAS-2 与自我客体化、肌肉驱动力和外貌-理想内化之间存在着显著的负相关，程度由小到大不等。我们还发现该测量具有良好的内部一致性和测试-再测可靠性。综上所述，我们的研究结果支持 BAS-2 在巴西性别开放者和变性男性中的心理测量特性。本研究为更好地了解性别开放人群和变性人群的积极身体形象的各个方面做出了宝贵的贡献。

期刊介绍： Body Image is an international, peer-reviewed journal that publishes high-quality, scientific articles on body image and human physical appearance. Body Image is a multi-faceted concept that refers to persons perceptions and attitudes about their own body, particularly but not exclusively its appearance. The journal invites contributions from a broad range of disciplines-psychological science, other social and behavioral sciences, and medical and health sciences. The journal publishes original research articles, brief research reports, theoretical and review papers, and science-based practitioner reports of interest. Dissertation abstracts are also published online, and the journal gives an annual award for the best doctoral dissertation in this field.
