Abstract:
This study aimed at assessing the psychometric properties of Eysenk Personality Questionnaire - Short form (EPQR-S) and Eysenk Personality Questionnaire-Abbreviated form (EPQR-A), to assertain their suitability to be used in Syria. In order to achieve the objectives of the study various methods of reliability and validity were used، and the two instruments under investigation were administered to a wide variety of samples. Validation data collected for each of the four subscales of EPQR-S, i.e. Psychoticism P, Extraversion E, Neuroticism N, and Lie L subscales showed satisfactory coefficients of reliability, and established convergent and divergent validity, as well as construct validity for these subscales. On the other hand, this study gave, to some extent, satisfactory coefficients of reliability and validity for the four subscales of EPQR-A, although lower than those obtained for the EPQR-S subscales. The researcher proposes that the EPQR-S is suitable to be used in Syrian context; whereas much attention should be taken in using the EPQR-A which ought to be used merely when it is difficult to use the EPQR-S. The researcher also suggests that the two instruments under consideration should be subjected to further investigations.
