Eysenck Personality Questionnaire-Revised (EPQ-R): A Systematic Review

The Eysenck Personality Questionnaire has been translated into multiple languages for cross-cultural research and application. Specifically, the questionnaire has been translated into Turkish, Hindi, Nepali, Portuguese and Spanish languages. These translations have been utilized in various studies to assess personality traits such as neuroticism, extraversion, psychoticism, and lying across different cultural and linguistic backgrounds. Psychometric properties of the EPQ translated into various other languages have been examined through reliability and validity analyses, including factor analysis, internal consistency, and construct validity assessments. Despite its widespread use, there is no documented evidence, to our knowledge, of any translations of the EPQ into Nigerian languages (except the Yoruba language). With the huge population of Ibibio-speaking people of Nigeria, translation of the EPQ into Ibibio language and other Nigerian languages will facilitate the study of personality traits in diverse populations, especially in clinical settings where the EPQ is widely used, contributing to a broader understanding of human personality. There is need to undertake a comprehensive review of previous studies that utilized the EPQ with a view to guiding efforts aimed at re-validating and translating the instruments into Nigerian languages.
