The Eysenck Personality Inventory (EPI) measures two pervasive, independent dimensions of personality, Extraversion-Introversion and Neuroticism-Stability, which account for most of the variance in the personality domain. Each form contains 57 “Yes-No” items with no repetition of items. The inclusion of a falsification scale provides for the detection of response distortion. The traits measured are Extraversion-Introversion and Neuroticism. When you fill out Eysenck’s Personality Inventory (EPI) you get three scores.
- The ‘lie score’ is out of 9. It measures how socially desirable you are trying to be in your answers.Those who score 5 or more on this scale are probably trying to make themselves look good and are not being totally honest in their responses.
- The ‘E score’ is out of 24 and measures how much of an extrovert you are.
- The ‘N score’ is out of 24 and measures how neurotic you are.
