Brazilian women are known to present high levels of physical appearance concerns, and data suggest they often compare themselves with others. Nevertheless, there is no validated instrument to systematically assess appearance comparisons in the Brazilian population. Thus, this study aimed to translate the Physical Appearance Comparison Scale-Revised (PACS-R) into Brazilian Portuguese and evaluate its factor structure, internal consistency, and convergent validity in Brazilian college women. The translated version into Brazilian Portuguese of the PACS-R was completed by 832 Brazilian college women and its factor structure was examined through exploratory and confirmatory factor analyses, internal consistency through McDonald's omega, and convergent validity through its associations with measures of eating disorder symptoms, internalization of appearance ideals, appearance-related sociocultural pressures, body satisfaction, and self-esteem. The results suggested an 11-item single-factor scale. The Brazilian Portuguese PACS-R showed adequate internal consistency and was significantly associated with all measures of convergent validity in the expected direction, indicating its adequate convergent validity. The Brazilian Portuguese PACS-R might be useful in the investigation of the appearance comparison among women in Brazil, as also in the study of body image and eating disorders.
巴西女性被认为对外表关注度较高，有数据表明她们经常将自己与他人进行比较。然而，目前还没有经过验证的工具可以系统地评估巴西人群中的外貌比较。因此，本研究旨在将修订后的外貌比较量表（PACS-R）翻译为巴西葡萄牙语，并评估其在巴西大学生女性中的因子结构、内部一致性和聚合效度。832 名巴西大学生女性完成了 PACS-R 的翻译版本，通过探索性和验证性因子分析来检验其因子结构，通过 McDonald's omega 检验内部一致性，通过与饮食障碍症状、外表理想内化、与外表相关的社会文化压力、身体满意度和自尊的测量值的相关性来检验聚合效度。结果表明存在一个 11 项的单一因素量表。巴西葡萄牙语 PACS-R 具有良好的内部一致性，并与聚合效度的所有测量值呈显著正相关，表明其具有良好的聚合效度。巴西葡萄牙语 PACS-R 可能有助于研究巴西女性之间的外貌比较，以及身体意象和饮食障碍的研究。
