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.
