Abstract
We examined the reliability and validity of the Japanese version of the modified short-form of the Eysenck Personality Questionnaire (MS-EPQ) . The MS-EPQ measures two dimensions of personality (neuroticism and extroversion) and comprises 12 questions with 4 response choices. Since it takes about 3 minutes to complete, this test can be used even when time is limited or when patients are suffering from concentration disturbances due to depression or comorbid physical disorders. High test-retest correlations, high internal consistency and high correlation with the original EPQ support the reliability and validity of the MS-EPQ. We conclude that the MS-EPQ is a suitable method for quickly assessing these two dimensions of personality.
