摘要

肌肉畸形症（Muscle dysmorphia，MD）的特征是对肌肉不足的极端关注，这种关注会引发病态行为和痛苦/损害。肌肉畸形障碍量表（MDDI）是一种被广泛使用的测量 MD 症状的方法，尽管有新的证据表明变性女性中存在以肌肉为导向的担忧风险，但该量表尚未在变性女性中得到验证。我们研究了 MDDI 的因子结构及其子量表的信度和效度，研究对象是参与美国性与性别少数群体成年人全国纵向队列研究的 181 名年龄在 19-73 岁之间的变性女性。我们使用了确认性因子分析来检验 MDDI 原始三因子结构（对体型的驱动力、外表不容忍、功能障碍）的模型拟合度。重新定义的三因素模型允许两个概念相关项目的残差协方差，显示出良好的整体拟合效果（χ2/df = 1.33，CFI =.94，TLI =.93，RMSEA =.06 [95 % CI =.01，.09]，SRR =.07）。此外，研究结果还证明了 MDDI 子量表在变性女性中的内部一致性、收敛性和区分性有效性。研究结果为在变性女性中使用 MDDI 提供了信息，并为支持未来对性别少数群体中的 MDDI 和 MD 症状的研究奠定了基础。

Factor structure and psychometric properties of the Muscle Dysmorphic Disorder Inventory (MDDI) among transgender women

Muscle dysmorphia (MD) is characterized by extreme preoccupation with insufficient muscularity that prompts pathological behaviors and distress/impairment. The Muscle Dysmorphic Disorder Inventory (MDDI) — a widely used measure of MD symptoms — has yet to be validated among transgender women, despite emerging evidence suggesting risk for muscularity-oriented concerns in this population. We examined the MDDI factor structure as well as the reliability and validity of its subscales in a sample of 181 transgender women ages 19–73 years who participated in a national longitudinal cohort study of U.S. sexual and gender minority adults. Confirmatory factor analysis was used to examine model fit for the original three-factor structure of the MDDI (drive for size, appearance intolerance, functional impairment). A re-specified three-factor model allowing covariance of residuals for two conceptually related items demonstrated good overall fit (χ²/df = 1.33, CFI =.94, TLI =.93, RMSEA =.06 [95 % CI =.01,.09], SRMR =.07). Moreover, results supported the internal consistency and convergent and discriminant validity of the MDDI subscales in transgender women. Findings inform the use of the MDDI among transgender women and provide a foundation to support future research on the MDDI and MD symptoms among gender minority populations.

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.
