Abstract

Background: Externalizing is a dimension of individual differences that undergirds and unites aggressive and impulsive personality traits to psychopathological disorders related to substance use and antisocial behavior. Objectives: The present study aims to establish parameters of construct validity for the Brazilian version of the Externalizing Spectrum Inventory. Method: This is a psychometrical correlacional study design. Two classical techniques of construct representation were implemented: unweighted least squares exploratory factor analysis and internal consistency analysis. The sample consisted of 258 participants of both sexes, from different undergraduate majors in two public universities in the state of Minas Gerais. Results: As expected in theoretical grounds, common factor analysis revealed a one second-order factor (externalizing dimension) with three subfactor structure (substance, antisocial and impulsivity/alienation dimensions). The alfa coefficients were very high, with indexes greater than 0,9 for the three subfactor as well as for the general factor. Discussion: Taken together, results bring evidences of validity and reliability of the Brazilian version of the Externalizing Spectrum Inventory in regard to it applicability in university students.
