The 101-item EPQ is a questionnaire to assess the personality traits of a person (Eysenck & Eysenck, 1994). The Revised Eysenck Personality Questionnaire in Chinese has been demonstrated to be reliable and valid for Chinese participants (Chen, 1998). The respondent rates each item on “Yes” or “No”. It applies to people over the age of 16. The inventory
contains four personality trait subscales: Psychoticism/Socialization (P), Extraversion/Introversion (E), Neuroticism/Stability (N), and Social Desirability (L). The L scale contains questions on which individuals tend to lie for social desirability, and the scoring standard is the same for everyone. If a participant received a score of one instead of zero on an L scale question, then this responsewas recorded as a lie. In each subscale, high score is on behalf of the former traits and low score is on behalf of the latter traits.
