Abstract

Objective: To validate the psychometric properties of the Eating Behavior Phenotypes Scale (EFCA) and to analyze the stability of the construct and its external validity in Brazilian Portuguese.

Subjects and methods: A total of 206 adult participants completed a self-administered survey designed to identify eating behavior phenotypes. Confirmatory factor analysis was performed, and internal consistency was assessed using Cronbach's alpha coefficient. Concurrent validity was evaluated through Pearson's correlation between EFCA scores and body mass index. Translation involved independent forward translation from Argentinian Spanish to Brazilian Portuguese, followed by back-translation from Brazilian Portuguese to Spanish. The Brazilian Portuguese version was administered following 100% agreement between the versions.

Results: The EFCA and its subscales in Brazilian Portuguese showed acceptable internal consistency (α = 0.83).

Conclusion: Confirmatory factor analysis indicated a good fit of the data to the proposed structure. No statistically significant correlation was found between the body mass index and each subscale or the total scale score. The translation and back-translation process yielded less than a 5% discrepancy between the versions.

巴西葡萄牙人饮食行为表型量表（EFCA）的验证：验证性因素分析和心理测量特性。

目的：验证巴西葡萄牙语饮食行为表型量表（EFCA）的心理测量特性，分析其结构的稳定性及其外部效度。对象和方法：共有206名成年参与者完成了一项旨在确定饮食行为表型的自我管理调查。进行验证性因子分析，并使用Cronbach's alpha系数评估内部一致性。通过EFCA评分与体重指数之间的Pearson相关来评估并发效度。翻译包括从阿根廷西班牙语到巴西葡萄牙语的独立正向翻译，然后从巴西葡萄牙语到西班牙语的反向翻译。巴西葡萄牙语版本在两个版本之间100%一致的情况下进行管理。结果：巴西葡萄牙语EFCA及其分量表具有可接受的内部一致性（α = 0.83）。结论：验证性因子分析表明数据与所提出的结构吻合良好。体重指数与各分量表或总分量表得分之间无统计学意义的相关性。在翻译和反翻译过程中，两个版本之间的差异不到5%。

期刊介绍： The Archives of Endocrinology and Metabolism - AE&M – is the official journal of the Brazilian Society of Endocrinology and Metabolism - SBEM, which is affiliated with the Brazilian Medical Association. Edited since 1951, the AE&M aims at publishing articles on scientific themes in the basic translational and clinical area of Endocrinology and Metabolism. The printed version AE&M is published in 6 issues/year. The full electronic issue is open access in the SciELO - Scientific Electronic Library Online e at the AE&M site: www.aem-sbem.com. From volume 59 on, the name was changed to Archives of Endocrinology and Metabolism, and it became mandatory for manuscripts to be submitted in English for the online issue. However, for the printed issue it is still optional for the articles to be sent in English or Portuguese. The journal is published six times a year, with one issue every two months.
