Measures of body dissatisfaction have not been validated for Mexican American (MA) women, who evaluate their bodies differently than Caucasian women. In this study, the psychometric properties of the EDI-III, Body Dissatisfaction Subscale (BDS) were examined in a sample of college-enrolled MA women using the Rasch Rating Scale Model. Criterion validity was also addressed. BDS evidenced good item fit, person and item reliability, once poorly correlated items were removed. Two qualitatively distinct dimensions of body dissatisfaction were identified: (1) overall body shape and stomach, and (2) the lower body. Validity of the scales was supported. Results suggest: MA women's satisfaction with overall body shape is not synonymous with attitudes toward their lower body.
身体不满的测量方法尚未在墨西哥裔美国（MA）女性中得到验证，她们对自己身体的评价与白人女性不同。在本研究中，使用拉施评分量表模型对就读于大学的MA女性样本进行了进食障碍评定量表第三版（EDI-III）身体不满分量表（BDS）的心理测量特性检验，同时也探讨了效标效度。去除相关性较差的项目后，BDS显示出良好的项目拟合度、人和项目的信度。确定了身体不满的两个质的不同维度：（1）整体身体形状和腹部，以及（2）下半身。量表的效度得到了支持。结果表明：MA女性对整体身体形状的满意度与她们对下半身的态度不同义。
