The Big Five Inventory (BFI) is a 44-item questionnaire used to assess an individual across five broad dimensions of personality: Extraversion, Agreeableness, Conscientiousness, Neuroticism, and Openness to Experience. Respondents indicate the extent to which they agree with statements describing various traits and behaviors associated with the Big Five factors on a 5-point scale. The BFI aims to provide a comprehensive yet concise measure of an individual's standing on the major dimensions of personality.
