Abstract
Factor analysis of the "Eysenck Personality Profiler - Short Form" (EPP-SF). The aim of this work is to analyse the factor structure of the short form of the Eysenck Personality Profiler (EPP-SF), a questionnaire recently elaborated by Eysenck, Wilson and Jackson (1996) that allows the assessment of the most important primary traits which constitute the major dimensions of personality. Results from multidimensional scaling and factor analyses of the EPP-SF in a Spanish sample of 946 subjects lend support to the english data. Factor structure of the scale shows a tridimensional composition and gives an acceptable level of homogeneity among the primary traits of each superfactor. Nevertheless, the primary trait of impulsivity shows relatively high loads in more of one personality dimension. This result is discussed from Eysenck's and other author's view about multidimensional nature of this personality disposition. Further analyses are required to testing the granted unidimensionality of the EPP-SF scales.
