Sexual minority individuals are at greater risk for the development of eating-disorder (ED) psychopathology. Despite the importance of understanding ED symptoms in sexual minority men, most ED measures were developed and validated in heterosexual, young adult, white women. The psychometric properties of ED measures in diverse populations remain largely unknown. The purpose of this study was to test: 1) whether the eight-factor structure of the Eating Pathology Symptoms Inventory (EPSI) replicated in sexual minority men and 2) group-level mean differences between gay and bisexual men on the eight EPSI scales. International participants (N = 722 sexual minority men from 20 countries) were recruited via the Grindr smartphone application. Confirmatory factor analysis (CFA) was completed using a weighted least square mean and variance adjusted estimator. Group differences in eating pathology between gay and bisexual men were tested using independent samples t-tests. The CFA model fit was good on all fit indices (CFI/TLI > 0.90, RMSEA < 0.06). Gay and bisexual men only differed on the EPSI Binge Eating scale. The results of this investigation suggest that the EPSI may be a useful tool for understanding eating pathology in this population. Using psychometrically sound assessment tools for sexual minority men is a vital piece of treatment planning and clinical decision making. The current study fills an important gap in the clinical and research literature by testing the validity and psychometric properties of a commonly used ED measure in sexual minority men.

性少数群体患进食障碍 (ED) 精神病理学的风险更大。尽管了解性少数男性的 ED 症状很重要，但大多数 ED 措施都是在异性恋、年轻的成年白人女性中制定和验证的。ED 措施在不同人群中的心理测量特性在很大程度上仍然未知。本研究的目的是测试：1) 饮食病理症状量表 (EPSI) 的八因子结构是否在性少数男性中得到复制，以及 2) 在八个 EPSI 量表上男同性恋和双性恋男性之间的群体水平平均差异。国际参与者 ( N = 来自 20 个国家的 722 名性少数男性）是通过 Grindr 智能手机应用程序招募的。使用加权最小二乘均值和方差调整估计量完成验证性因素分析 (CFA)。使用独立样本t测试男同性恋和双性恋男性之间饮食病理学的群体差异-测试。CFA 模型在所有拟合指数上的拟合都很好（CFI/TLI > 0.90，RMSEA < 0.06）。男同性恋者和双性恋者仅在 EPSI 暴食量表上有所不同。这项调查的结果表明，EPSI 可能是了解该人群饮食病理的有用工具。对性少数男性使用心理测量学上合理的评估工具是治疗计划和临床决策的重要组成部分。目前的研究通过测试性少数男性常用的 ED 测量的有效性和心理测量特性，填补了临床和研究文献中的一个重要空白。
