Summary

The Five Factor Personality Inventory (FFPI) was translated and adapted to a Spanish population of 567 subjects. A principal component analysis using orthogonal Procrustes rotation replicated the five-component structure of the original FFPI questionnaire. The coefficients of congruence between the loadingmatrices obtained in the Dutch sample and the Spanish sample were also computed showing high factorial convergence. The Spanish version of the FFPI showed adequate reliability. Further, convergent and discriminant validity were studied using other well-known Big Five and PEN questionnaires. The results fully supported the psychometric properties of the FFPI questionnaire in the present population.
