Psychometric properties of Eysenck Personality Questionnaire-Revised (EPQ-R) Short Scale in Greece

The aim of the present investigation was to evaluate the reliability, internal and test-retest, concurrent and construct validity of the Eysenck Personality Questionnaire-Revised Short Scale (EPQ-R S) in a Greek sample. The EPQ-R S is a 48-self-report questionnaire to assess the dimensions of personality, neuroticism, extraversion, psychoticism. It also includes a Lie scale. The test was translated/adapted by the authors and back-translated by a person whose native language was English. The sample consisted of 946 individuals (422 males, 524 females) aged 16-73-years-old. The EPQ-R S and the Eysenck Personality Questionnaire-Adult (EPQ-A) as the latter was adapted for the Greek population by Demetriou were used to find the concurrent validity of the scale. Reliability coefficients both internal and test-retest, as well as mean inter-item correlations were found to be satisfactory for E, N, L, and low for P. The E, N, L dimensions of EPQ-R S had high correlations with the corresponding dimensions of EPQ-A, but not the P. Finally, a factor analysis of the test indicated the existence of four factors, E, N, P, L which was not confirmed by CFA.
