The MEQ was firstly translated from English to Portuguese, administered to 10 persons, and then submitted to brainstorming in a group of 4 persons for individual and verbal reproduction, item by item. Back-translation was executed based on first translation and from brainstorming to the origin language. Soon after, it was translated again into Portuguese. All the process was analyzed by a committee of specialists, which emitted a decision and the pertinent comments. The descriptive judges’ analysis was done verifying frequencies and percentages. Considering the decision of the specialists, the final version of the MEQ (Brazilian Adaptation) was constructed.
