Background: Loss of control over eating is a key feature of the most prevalent eating disorders. The Loss of Control over Eating Scale (LOCES) enables a thorough assessment of loss of control over eating. Objective: This study empirically evaluated the translation of the LOCES from eng to Brazilian por. Methods: The scale was translated to Brazilian por and back translated to eng in order to check accuracy of the translation. Two hundred and ninety-three medicine and nursing students, 60 males and 233 females, 18-55 years old, with mean body mass index (BMI) 23.2 kg/m(2) (SD 4.1), recruited between August and December 2014, answered the Brazilian por LOCES. An exploratory factor analysis was performed. Results: Exploratory factor analysis of the Brazilian por LOCES showed three distinct factors of the loss of control over eating (disgust/negative sensations, cognitive experiences/dissociation, and "positive" effects) as well as moderate consistency with previous reports of exploratory factor analysis of the eng version. Discussion: This study showed satisfactory translation of the LOCES from eng to Brazilian por, which is now ready for further validation.
