The present study developed the Muscularity Bias Internalization Scale (MBIS), a measure of muscularity bias internalization, which assesses the extent to which an individual endorses muscularity-based stereotypes and engages in negative self-evaluations due to muscularity. In Study 1, a pool of candidate items was developed. By using exploratory factor analysis (EFA) on a sample of 300 Chinese adult men (M = 29.98 years, SD = 7.81), 14 items from the item pool were retained. The 14-item MBIS contained three factors. In Study 2, a second sample of 300 Chinese adult men (M = 29.50 years, SD = 7.50) was used to confirm the factor structure of the MBIS, as well as to examine its reliability and validity. Confirmatory factor analysis (CFA) further confirmed the three-factor structure of the MBIS with a good model fit. The MBIS showed high internal consistency reliability and high two-week test-retest reliability. The MBIS also showed good construct validity with measures of drive for muscularity, muscularity-oriented disordered eating, and muscle dysmorphia symptoms. The newly developed MBIS may help understand the role of muscularity bias internalization in the development and maintenance of muscularity-oriented body image and muscularity-oriented disordered eating.
本研究开发了肌肉偏见内化量表（MBIS），这是一种衡量肌肉偏见内化的方法，评估个体对肌肉为基础的刻板印象的认可程度，以及由于肌肉而进行的自我负面评价。在研究 1 中，开发了一组候选项目。通过对 300 名中国成年男性（M=29.98 岁，SD=7.81）的样本进行探索性因素分析（EFA），从项目池中保留了 14 个项目。MBIS 由 14 个项目组成，包含三个因素。在研究 2 中，使用 300 名中国成年男性（M=29.50 岁，SD=7.50）的第二个样本，对 MBIS 的因素结构进行验证，以及检验其信度和效度。验证性因素分析（CFA）进一步证实了 MBIS 的三因素结构，具有良好的模型拟合度。MBIS 表现出较高的内部一致性信度和两周的重测信度。MBIS 还与肌肉驱动、肌肉导向的饮食失调和肌肉变形症症状等测量指标具有良好的结构效度。新开发的 MBIS 可能有助于理解肌肉偏见内化在肌肉导向的身体意象和肌肉导向的饮食失调的发展和维持中的作用。
