Brazilian Mini-Markers of Personality measure the Five-Factor Model with 25 adjectives frequently used for describing individual differences in Brazilian Portuguese. However, up to date, there were no studies focusing on its psychometric properties in adolescent groups. Therefore, the aim of the present study was to evaluate the factor structure of the instrument in two adolescent student samples. The Study I used data from 208 high school students (mean age=15.97; SD= 1.00) and showed an oblique solution composed of five principal components and 20 markers. This structure was then tested with confirmatory factor analysis using data from 280 school and high school students (mean age=15.53; SD= 1.00). Fit indexes showed that an oblique five-factor model performed better than theoretically-derived concurrent structures. Results showed that a 20 marker version of the instrument is adequate for use with adolescents in Brazil.
