BACKGROUND: The Exercise Commitment Scale (CES) evaluates commitment, attitude and behavior regarding exercise in eating disorders patients. OBJECTIVE: Translation and cultural adaptation of the CES for Portuguese (BRA), content validation and analysis of internal consistency. METHODS: This study involved five steps: (1) translation, (2) re-translation, (3) technical review and evaluation semantics, (4) content validation by professionals - judges, (5) assessment of the instrument in a sample of students, by assessing the degree of understanding and analysis of internal consistency by Cronbach's a coefficient. RESULTS: The scale was translated and adapted. It was considered easy to understand (degree of understanding from 4.3 to 4.9) and showed acceptable consistency coefficients (Cronbach's a: 0.60 to 0.79). DISCUSSION: Satisfactory results of this adaptation process allow the recommendation of the CES Brazilian version. Analysis is needed of construct and factorial validation, and of reproducibility.
