The Eysenck Personality Questionnaire Revised – Abbreviated (EPQR-A) : psychometric properties of the Brazilian Portuguese version

Abstract

Introduction: The Eysenck Personality Questionnaire Revised – Abbreviated (EPQR-A) consists of 24 items for assessment of the three fundamental personality traits (psychoticism, extraversion, and neuroticism) and a validity scale (lie scale). Our objectives were to assess the psychometric properties of a version of this instrument culturally adapted for Brazil. Method: 321 participants were recruited using a non-probabilistic method. Results: Internal consistencies ranged from minimally acceptable to respectable, except for the psychoticism domain. Higher neuroticism scores were associated with higher depression and anxiety scores, higher extraversion scores were associated with lower levels of depression symptoms, and higher psychoticism scores were associated with higher levels of depression symptoms. Conclusion: Our findings describe sustainable psychometric properties for the Brazilian Portuguese version of EPQR-A.
