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

This study was carried out in order to evaluate the psychometric properties of the Persian version of the Eysenck Personality Questionnaire-Revised Short-Scale (EPQ-R S) in Iranian sample. The EPQ-R S is a 48-selfreport questionnaire to assess the dimensions of personality, neuroticism, extraversion, psychoticism. It also includes a Lie scale. The EPQ-R S and NEO Five-Factor Inventory (NEOFFI- R) is completed by a sample of 343 Tabriz university students (168 males, 175 females) aged 18-35. Reliability coefficients (internal and test-retest, as well as mean interitem correlations) were found to be satisfactory for E, N, L and low for P. The validity of the EPQ-R S is evaluated by the correlations of the subscales of EPQ-R S with the subscales of NEO-FFI-R, exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). The E, N dimensions of EPQ-R S had high correlations with the corresponding dimensions of NEO-FFI-R. EFA results show that the EPQR S has a very robust four-factor structure. How ever, CFA shows a misfit of four-factor simple structure model.
