The NEO-PI-R is one of the most frequently used questionnaires of personality following the Five Factor Personality model in both, research and applied psycho-logy. This instrument has a shorter version without facets of the NEO-FFI, as well as a recently revised version called NEO-FFI-R which is useful for applications where only the five dimensions are to be evaluated. This study provides psychometric data about the validity and reliability of the two short versions with a general population’s and Spanish university undergraduate student samples. The scores frequency distribution in both scales meet normality assumptions with Skewness and Kurtosis values in the +1 range. Means, standard deviations and internal consistencies are also very similar to original data. The five factor structure in both short versions is equivalent to that obtained in the corresponding American stu-dies, as shown by factorial congruence coefficients. These results are equivalent to the original studies, supporting its structural validity and reliability. Norms are provided to be used for the applied psychologist.
