RELIABILITY AND VALIDITY OF A JAPANESE VERSION OF THE SHORT-FORM EYSENCK PERSONALITY QUESTIONNAIRE - REVISED

The reliability and the validity of a Japanese version of the short-form Eysenck Personality Questionnaire-Revised were examined for 329 college students and 253 adults. Coefficient alpha reliabilities for the four scales (Psychoticism, Extraversion/Introversion, Neuroticism, and Lie) were greater than 0.71 except for Psychoticism. Test-retest reliability of the four scales over 6 months ranged from 0.70 to 0.85, indicating a substantial stability. A confirmatory factor analysis supported the original theoretical structure of the four personality dimensions as proposed by Eysenck, Eysenck, and Barrett in 1985. Concurrent validity of the revised short-form was evaluated through the comparison of the four scores with the scores on the Maudsley Personality Inventory and the Sixteen Personality Factor Questionnaire. Over-all, the Japanese version of the revised short-form appears to be comparable to the original English version and would be useful for measuring personality in a wide range of settings.
