The Negative Physical Self Scale (NPSS) is a measure of body dissatisfaction that was developed for administration within an Asian sample and has recently been translated to English and validated for use in North American female samples. The aim of the present study was to examine the factor structure and measurement invariance of the English-translated version of the NPSS across three ethnic groups (i.e., Caucasian, Asian, and other) using a sample of men residing in North America. Additionally, the internal consistency, convergent validity, and incremental validity of the NPSS were examined. A sample of 534 young (aged between 18 and 25) North American men completed self-report measures of the NPSS, the Body Shape Questionnaire, the Eating Disorder Examination Questionnaire, and the Male Body Attitudes Scale. Confirmatory factor analysis was conducted on two hypothesized models. The results supported the second-order factor structure (four factors with three subdimensions). Overall, we found that the factor structure and factor loadings of the NPSS were equal in participants across three broad ethnic categories (i.e., Caucasian, Asian, and other). Likewise, the NPSS displayed first-order scalar invariance. Further, the NPSS test scores demonstrated high internal consistency, strong convergent validity, and incremental validity over and above the existing measures of body dissatisfaction, body attitudes, and disordered eating. In sum, the English version of the NPSS is a valid and appropriate measure to assess body dissatisfaction in men residing in North America.

负面身体自我量表 (NPSS) 是一种衡量身体不满的量表，专为亚洲样本设计，最近已被译为英文，并经过验证可用于北美女性样本。本研究的目的是使用居住在北美的男性样本，检验 NPSS 英文翻译版在三个族裔群体（即白种人、亚洲人和其他人）中的因子结构和测量不变性。此外，还检验了 NPSS 的内部一致性、聚合效度和增量效度。534 名年轻（年龄在 18 至 25 岁之间）的北美男性完成了 NPSS、身体形状问卷、饮食失调检查问卷和男性身体态度量表的自我报告测量。对两个假设模型进行了验证性因素分析。结果支持二阶因子结构（四个因素，三个亚维度）。总体而言，我们发现 NPSS 的因子结构和因子负荷在三个广泛的族裔类别（即白种人、亚洲人和其他人）的参与者中是相等的。同样，NPSS 表现出一阶标度不变性。此外，NPSS 测试分数表现出较高的内部一致性、与现有身体不满、身体态度和饮食失调测量高度的聚合效度和增量效度。总之，NPSS 的英文版本是评估居住在北美的男性身体不满的有效且适当的测量工具。（PsycInfo 数据库记录（c）2022 APA，保留所有权利）。
