Reliability, factor structure and validity of the Dutch Eysenck Personality Profiler

The Eysenck Personality Profiler (EPP) is a questionnaire measuring 21 primary personality traits that are thought to constitute the three supertraits of Extraversion, Neuroticism and Psychoticism. The present study examined the reliability, factor structure and convergent validity of the Dutch translation of the EPP in a sample of introductory psychology students (N=215). Results indicate that the internal consistency of most EPP scales was satisfactory. Furthermore, exploratory and confirmatory factor analyses showed that the to-be-expected three-factor structure provided a reasonable fit for EPP data. Finally, Extraversion, Neuroticism and Psychoticism were found to correlate in a meaningful way with the “big 5” supertraits as indexed by the Five-Factor Personality Inventory.
