OBJECTIVE
Adapt and validate the Brazilian Portuguese version of the Body Checking and Avoidance Questionnaire (BCAQ).
METHODS
The study consisted of: translation and back translation; technical review and assessment of semantic equivalences, factor analysis and discriminant and concurrent validity in a sample of subjects with and without eating disorders.
RESULTS
The instrument was adapted and was found to be easy to understand (mean scores higher than 3.4; maximum score: 5.0) and showed excellent concordance (Cronbach's alpha: 0.94). Factor analysis identified five components with eigenvalues greater than 1. It was able to discriminate the two groups (p<0.001) and correlated with the Eating Attitudes Test (EAT) (r=0.50), body shape questionnaire (BSQ) (r=0.68) and Beck Depression Inventory (BDI) scales (0.51).
DISCUSSION
The Brazilian Language version showed suitable internal consistency and external validation, and was easy to understand. The results were similar to the original version and its use is recommended for evaluation of body checking in the Brazilian population in subjects with or without eating disorders.
目的
改编并验证巴西葡萄牙语版身体检查和回避问卷（BCAQ）。
方法
研究包括：翻译和回译；技术审查和语义等价性评估、在有无饮食障碍的受试者样本中进行因子分析和判别及同时效度分析。
结果
该工具经过改编，易于理解（平均得分高于 3.4；满分：5.0），并且具有极好的一致性（Cronbach's alpha：0.94）。因子分析确定了五个特征值大于 1 的分量。它能够区分两个组（p<0.001），并与饮食态度测试（EAT）（r=0.50）、体型问卷（BSQ）（r=0.68）和贝克抑郁量表（BDI）（r=0.51）相关。
讨论
巴西语版本显示出适当的内部一致性和外部验证，并且易于理解。结果与原始版本相似，建议在有无饮食障碍的巴西人群中使用该问卷评估身体检查。
