Brief psychometric measures for personality assessment have received increasing attention in the psychological literature. Up to date, however, there was a lack of brief personality measures in Brazil. The present study explored the psychometric properties of Big Five mini-markers derived from an instrument originally composed of 64 items. Participants were 674 undergraduate students (mean age = 23.5 years; SD = 6.46). Exploratory factor analyses as well as theoretical-semantic criteria were used to select a brief set of personality markers. The final factor solution was composed of 25 markers, five for each Big Five dimension, explaining 53.9% of the variance. Finally, we discuss the need to investigate the convergent validity of the measure, and considerations regarding its potential usefulness.
