Shortened versions of the NEO-PI-R: the NEO-FFI versus the NEO-FFI-R

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 psychology. 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 studies, 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.
