Abstract

Muscularity bias internalization (MBI) refers to one’s beliefs in negative muscularity-based stereotypes and negative self-evaluations due to muscularity. Empirical research shows that MBI significantly correlates with muscularity-oriented eating and body image disturbances. The Muscularity Bias Internalization Scale (MBIS) measures MBI and has been validated in general adult populations. Given that evidence supports a higher risk of eating and body image disturbances in Transgender and Gender-Diverse (TGD) people compared to their cisgender counterparts, validating the MBIS in TGD people is essential to further clarifying disparities in eating and body image disturbances in this population. With a sample of 410 Chinese TGD adults, exploratory and confirmatory factor analyses supported a two-factor structure. Comparisons of the second-order and bifactor models favored the second-order model. The MBIS showed good internal consistency and sound construct validity. Strong measurement invariance was confirmed across transgender men, transgender women, and gender-diverse groups, suggesting that these groups interpreted the MBIS similarly and that conclusions of differences in MBI across TGD adults can be considered true group differences. Specifically, transgender men reported the highest MBIS scores, followed by gender-diverse individuals, and then transgender women. These findings suggested that the MBIS appears to be a psychometrically sound instrument of MBI in Chinese TGD adults.

中国跨性别及多性别成人肌肉偏倚内化量表的验证

肌肉力量偏见内化（MBI）是指一个人对基于肌肉力量的负面刻板印象和由于肌肉力量而产生的负面自我评价的信念。实证研究表明，MBI与肌肉导向饮食和身体形象障碍显著相关。肌肉偏倚内化量表（MBIS）测量MBI，并已在一般成人人群中得到验证。鉴于有证据表明，变性人和性别多样性（TGD）人群与顺性人群相比，饮食和身体形象障碍的风险更高，验证TGD人群的MBIS对于进一步阐明该人群饮食和身体形象障碍的差异至关重要。以410名中国TGD成人为样本，探索性和验证性因素分析支持双因素结构。二阶模型和双因子模型的比较更有利于二阶模型。MBIS具有良好的内部一致性和良好的结构效度。在跨性别男性、跨性别女性和不同性别的人群中证实了很强的测量不变性，这表明这些群体对MBIS的解释相似，TGD成人中MBI差异的结论可以被认为是真正的群体差异。具体来说，跨性别男性报告的MBIS得分最高，其次是性别多样化的个体，然后是跨性别女性。这些发现表明，MBIS似乎是中国TGD成人MBI的心理测量学上可靠的工具。

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.
