Scales measuring neuroticism, extraversion, psychoticism, and lie taken from the Eysenck Personality Inventory (EPI) and the Eysenck Personality Questionnaire were correlated with self-report and peer-rating measures of the 5-factor model--neuroticism, extraversion, openness to experience, agreeableness, and conscientiousness--in 274 men and 179 women (aged 24-96 yrs). Findings suggest that (1) neuroticism and extraversion factors from the 2 systems match well; (2) sociability and impulsivity are distinguishable traits, but both fall within the broad domain of extraversion; (3) the EPI Lie 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.
