The need for a comprehensive model of personality traits acceptable to the entire community of personality researches has often been acknowledged. In this article, two such models are compared. Eysenck scales measuring neuroticism, extraversion, psychoticism and lie are correlated with self-report and peer-rating measures of the five-factor model-neuroticism, extraversion, openness to experience, agreeableness and conscientiousness-in a sample of adult men and women. Findings suggest that: (1) neuroticism and extraversion factors from the two systems match well; (2) sociability and impulsivity are distinguishable traits, but both fall within the broad domain of extraversion; (3) the EPI L scale measures aspects of several substantive traits rather than a response bias; (4) openness to experience is not well-represented in the Eysenck system; and (5) psychoticism corresponds most closely to the low poles of agreeableness and conscientiousness.
