The presented research is fundamental for scientific and applied community that needs to assess personality construct, for whatever reasons. The sample size is excellent and the effort made to develop a brief and reliable measure is present in the manuscript. However, I have considerations to make and I hope that all of them will be of use to the authors to enrich this research. Feel free to consider them. First: a review of the text in English is carried out, it is essential. The text seemed more likely to a literal translation than the ideas proposed by the authors. The text in Portuguese should probably sound different. Second, the method, analysis, result and discussion sections should be better organized. The text presents data on the method and results in the discussion. I consider ordering the sequence of the text and ideas. Third: method section needs a major revision (the considerations are present in the attached manuscript). Ethics committee approval is critical. As a reviewer, I consider suitable another review of the text just with this condition. Fourth: the authors could use more appropriate analyzes, especially considering a study with such expressive and representative sample of Brazilian context. Fifth: there are more current references that can be used. It is worth a review in this part.
