The Drive for Muscularity Scale (DMS) is a commonly used measure used to assess the pursuit of muscularity. However, the factor structure of this measure has yet to be confirmed in a sample of sexual minority women. Moreover, the invariance of this measure across gender has also yet to be explored. The aim of the present study was, therefore, to conduct a confirmatory factor analysis (CFA) of the DMS in samples of both cisgender sexual minority men and women, and subsequently evaluate the measurement invariance by gender. The sample consisted of 962 cisgender sexual minority young adult men ( = 479) and women ( = 483). A series of CFAs were conducted, assessing both the one-factor and two-factor solutions of the DMS, with and without the inclusion of item 10 ("I think about taking anabolic steroids"). Across cisgender sexual minority young adult men and women, the 14-item two-factor solution demonstrated most appropriate fit, although the 15-item two-factor solution was also adequate among only women. Measurement invariance analyses indicated that the 14-item two-factor DMS can be used in samples of both cisgender sexual minority men and women. The present study was novel in exploring the factor structure of the DMS in sexual minority women and measurement invariance by gender; however, future research is needed to further corroborate these findings and assess measurement invariance by sexual orientation and race.
肌肉量追求量表（DMS）是一种常用的用于评估对肌肉量追求程度的测量工具。然而，该测量工具的因子结构在性少数群体女性样本中尚未得到证实。此外，该测量工具在不同性别间的不变性也尚未被探究。因此，本研究的目的是对顺性别性少数群体男性和女性样本中的DMS进行验证性因子分析（CFA），并随后按性别评估测量不变性。样本包括962名顺性别性少数群体年轻成年男性（ = 479）和女性（ = 483）。进行了一系列CFA，评估了DMS的单因子和双因子解决方案，包括是否纳入第10项（“我考虑使用合成代谢类固醇”）。在顺性别性少数群体年轻成年男性和女性中，14项双因子解决方案显示出最合适的拟合度，不过15项双因子解决方案在仅女性样本中也足够。测量不变性分析表明，14项双因子DMS可用于顺性别性少数群体男性和女性样本。本研究在探究性少数群体女性中DMS的因子结构以及按性别评估测量不变性方面具有创新性；然而，未来需要进一步研究来证实这些发现，并按性取向和种族评估测量不变性。
