The aim of this study was to translate and adapt the BRIEF into Portuguese. The process of translation and adaptation followed the steps recommended in the international literature. Besides that, an initial analysis of psychometric properties was performed. The final version was administered in a sample of 277 parents, 282 teachers of children between 5 and 11 years old, and 112 adolescents between 11 and 18 years old from the city of Rio de Janeiro. The Cronbach Alphas ranged between .901 and .957 considering the three forms. The main component analysis extracted two dimensions. The internal consistency values found in the Brazilian version resembled the original version, ensuring good quality in the process of translation and adaptation.
