The aim of this study was to assess the psychometric properties (validity and reliability) of the Portuguese adaptation of the NEO Five-Factor Inventory (NEO-FFI) and to compare the obtained structure to the original North American version. The methods of analysis used for cross-validation of the factorial structure were the Principal Axis Factoring (PAF) and the Confi rmatory Factor Analysis (CFA). PAF reproduced the original structure of NEO-FFI and CFA revealed a satisfactory fi t of single-factor models for the fi ve dimensions. The reliability analysis showed high values of internal consistency which are congruent with previous international adaptations of the NEO-FFI. Multidimensional analysis showed signifi cant main effects of gender and academic qualifi cations on personality using age as covariant. The fi ndings suggest that the Portuguese version of the NEO-FFI is a reliable instrument to measure the fi ve dimensions of personality.
