Eysenck’s Personality Inventory

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.
To interpret the scores, your E score and your N score are plotted on a graph from which you can read your personality characteristics. The nearer the outside of the circle you are, the more marked are the personality traits. Please note that the EPI is a very simplistic type of personality measurement scale, so if you have come out as a personality that does not match what you thought before you took the test, you are probably right and the test is probably wrong!
