This research presents the psychometric properties and indicators of factorial validity related to the Brazilian version of love styles scale - LAS. The purpose of this measure is to evaluate six cognitive dimensions of romantic love, according to the theory proposed by John Lee: Eros, Storge, Ludus, Mania, Pragma and Agape. Five hundred and nine people of both sexes took part on the study, 222 of whom were men (43,6%) and 287 were women (56,4%). Mean participant age was 27,9 years old (SD = 9,6) for the male group and 26,4 years (SD = 8,5) for the female group. Participants answered to an online version of the original 42-item Likert scale that had been translated to Portuguese. Exploratory factor analysis results demonstrated consistency on the scale’s six dimension structure, and independence among the resulting factors. Scales’ Cronbach alpha reliability coefficient ranged from 0,55 to 0,81, indicating the viability to use that measure.
