The present study was designed to develop and obtain construct validity for a scale to measure extraversion in the Big Five model. In this model, extraversion is comprised by traits that describe level of communication, assertivity, gregariousness, search for pleasure, among others. The participants in the construct validity study of the Extraversion Factorial Scale (EFE) were 1.084 individuals, from five states in Brazil, of both sexes, with high school or university level of education. Factor analyses were conducted to determine the EFE dimensions. A 4-factor solution was found to be more adequate. The factors found were named Communication, Pride, Assertiveness, and Social Interaction. Cronbach's alphas were .90, .78, .78, and .83 respectively. The general scale presented internal consistency level of .91.
