title: Psychometric evaluation of the "Body Checking and Avoidance Questionnaire--BCAQ" adapted to Brazilian Portuguese.
abstract: 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).
  
  
  CONCLUSIONS
  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.
