The present study investigated the psychometric properties of the Brazilian adaptation of the Multidimensional Body-Self Relations Questionnaire-Appearance Scales, a widely used instrument in body image research.
We translated the MBSRQ-AS and determined its psychometric properties among 2 community samples, totaling 387 men and 381 women, and 1 college sample of 104 men and 133 women, aged from 16 to 67 years old (totaling 1005 participants). Near half of the sample (n = 606) was recruited online (SurveyMonkey Database) and the other half was personally recruited from universities, technical schools and libraries.
The translated version was similar to the original, and the items were easily understood. After the exclusion of the negatively worded questions, the Brazilian version had the same factor structure as the original MBSRQ-AS. Internal consistency ranged from .73 to .90 and test-retest reliability indices ranged from .76 to .92. The measure captured sex and weight status differences. Women reported significantly higher levels of investment in appearance, lower levels of satisfaction with specific parts of the body, higher concerns with being overweight, and classified themselves as heavier than men. Overweight and obese men and women reported lower satisfaction with specific parts of their bodies, higher concerns with being overweight, and classified themselves as heavier than their normal weight counterparts. Convergent validity was demonstrated by the significant correlations between the MBSRQ-AS subscales and investment in appearance, internalization of beauty ideals, disordered eating and self-esteem.
In summary, the Brazilian MBSRQ-AS appears to be a good option for researchers in the country. Furthermore, the study provides substantial parameters for comparison with other adaptations of the instrument around the world.

本研究旨在调查巴西版多维身体自我关系问卷-外貌量表（MBSRQ-AS）的心理测量特性，该量表是身体意象研究中广泛使用的工具。
我们翻译了 MBSRQ-AS，并在两个社区样本中确定了其心理测量特性，共有 387 名男性和 381 名女性，以及一个由 104 名男性和 133 名女性组成的大学生样本，年龄在 16 至 67 岁之间（共 1005 名参与者）。样本的近一半（n=606）是通过在线（SurveyMonkey 数据库）招募的，另一半是从大学、技术学校和图书馆亲自招募的。
翻译版本与原文相似，问题易于理解。在排除了负面表述的问题后，巴西版具有与原始 MBSRQ-AS 相同的因子结构。内部一致性范围为.73 至.90，重测信度指数范围为.76 至.92。该测量方法捕捉到了性别和体重状况的差异。女性报告对外表的投资明显更高，对身体特定部位的满意度较低，对超重的担忧更高，并且自我评估的体重比男性更重。超重和肥胖的男性和女性报告对身体特定部位的满意度较低，对超重的担忧更高，并且自我评估的体重比正常体重的人更重。MBSRQ-AS 子量表与外表投资、美丽理想内化、饮食紊乱和自尊之间的显著相关性证明了其收敛效度。
总的来说，巴西 MBSRQ-AS 似乎是该国研究人员的不错选择。此外，该研究为与世界各地该工具的其他改编版本进行比较提供了大量参数。
