Eysenck Personality Questionnaire

Comprehensive handbook of psychological …, 2003

"The Eysenck Personality Questionnaire – Revised (EPQ-R) and the Eysenck Personality Profiler (EPP) are designed to measure the three traits of extraversion, neuroticism and psychoticism. In addition both contain a scale to measure socially desirable responding. The EPQ-R contains just these scales, the EPP measures facets of the personality scales. Both scales are available in long and short forms, the long form of the EPQ-R comprising 100 items, the short form 48 items. For the EPP the long form contains 440 items, the short form 200 items. The tests were developed by Hans Eysenck and his co-workers (principally Sybil Eysenck) over a 40 year period from 1952 to 1992, beginning with the Maudsley Medical Questionnnaire (MPQ; 1952), the Maudsley Personality Inventory (MPI; 1952), the Eysenck Personality Inventory (EPI; 1964), the Eysenck Personality Questionnaire (EPQ; 1975 – this scale included psychoticism for the first time), the Eysenck Personality Questionnaire – Revised (1985) and the Eysenck Personality Profiler (1992). The developments of the scales matched Eysenck’s theory about the underlying structure of personality, and its biological or anatomical underpinnings. Eysenck always attempted to pin individual differences to differences in brain or nervous system structure. In the case of extraversion, there has been some considerable success, but as yet there has been little success in finding biological correlates of neuroticism and psychoticism. The EPQ has been, and continues to be, widely employed in psychological practice and research. It has been translated into a number of languages, and support has been found for the factor structure in many different cultures and languages."

The short scale of the Eysenck Personality Questionnaire-Revised (EPQR-S; H. J. Eysenck & S. B. G. Eysenck, 1992) is a 48-item personality questionnaire primarily designed to measure an individual's level of extraversion (vs. introversion) and neuroticism. Although L. J. Francis, L. B. Brown, and R. Philipchalk (1992) created the Eysenck Personality Questionnaire Revised-Abbreviated (EPQR-A), an even briefer version of the EPQR-S, the reliability coefficients of some of the measures have been less than satisfactory (S. Forrest, C. A. Lewis, & M. Shevlin, 2000)

A sample of 331 undergraduate students in Germany completed the German translation of the short form Revised Eysenck Personality Questionnaire (EPQR-S; Eysenck, Eysenck, & Barrett, 1985). The findings support the psychometric properties of the extraversion, neuroticism and lie scales. The psychoticism scale, however, was found to be less satisfactory.

The Eysenck Personality Pro®ler (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 con®rmatory factor analyses showed that the to-be-expected three-factor structure provided a reasonable ®t 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. 7

In this article, we develop a revised short form of the original Eysenck Personality Profiler (EPP; HJ Eysenck & Wilson, 1991). In addition, we address topics of broad theoretical importance such as the recurrent empirical finding of correlations between conceptually orthogonal personality dimensions and the possibility that gender differences in these dimensions are partly spurious.

Based on the P-E-N Model, the Eysenck Personality Questionnaire -Revised (EPQ-R; S. Eysenck et al., 1985) is an internationally well-known personality assessment instrument. This questionnaire measures the three fundamental personality dimensions: Psychoticism, Extraversion, and Neuroticism (also includes a Lie/Social Desirability scale). The aim of the present paper consists in the examination of the factorial structure of the EPQ-R in the Portuguese context and its psychometric properties (validity and reliability). Using a large sample (N=1689, 16-60 years), the construct validity was examined through exploratory factor analysis (EFA) and confirmatory factor analysis (CFA), and the test reliability through internal consistency analysis and test-retest reliability (temporal stability between 4 to 8 weeks). In general, the EPQ-R showed an adequate reliability and validity indices, replicating on the Portuguese context the factor structure of its original version (English). These results demonstrate that the EPQ-R conveniently measures the Neuroticism, Extraversion, and Psychoticism constructs, defined by H. Eysenck, and the adequacy of the EPQ-R to the Portuguese population as a personality assessment instrument.
