Purpose This study aimed to evaluate the psychometric properties and scoring pattern of the Brazilian version of the three-factor eating questionnaire-r21 (TFEQ-R21). Methods: Data were collected from 410 undergraduate students. Confirmatory factor analysis was conducted to examine the factor structure of the TFEQ-R21. Convergent and discriminant validity also was assessed. Cluster analysis was performed to investigate scoring patterns. Results: In assessing the quality setting, the model was considered satisfactory (chi (2)/gl = 2.24, CFI = 0.97, TLI = 0.96, RMSEA = 0.05). The instrument was also considered appropriate in relation to the discriminant and convergent validity. There was a positive correlation between body mass index and the dimensions of cognitive restraint (r(s) = 0.449, p < 0.001) and emotional eating (r(s) = 0.112, p = 0.023). Using cluster analysis three respondent profiles were identified. The profile A was associated with appropriate weight, the B was characterized by high scores in cognitive restraint dimension, and the cluster C focused individuals who had higher scores on the uncontrolled eating and emotional eating dimensions. Conclusion: The Brazilian version of TFEQ-R21 has adequate psychometric properties, and the identified response profiles offer a promising prospect for its use in clinical practice, in weight loss interventions.
