Revised NEO Personality Inventory

The Revised NEO Personality Inventory (NEO PI-R) is a personality inventory that assesses an individual on five dimensions of personality. These are the same dimensions found in the Big Five personality traits. These traits are openness to experience, conscientiousness, extraversion(-introversion), agreeableness, and neuroticism. In addition, the NEO PI-R also reports on six subcategories of each Big Five personality trait (called facets).

Historically, development of the Revised NEO PI-R began in 1978 when Costa and McCrae published a personality inventory.[1] The researchers later published three updated versions of their personality inventory in 1985,[2] 1992,[3] and 2005.[4] These were called the NEO PI (Neuroticism, Extraversion, Openness Personality Inventory), NEO PI-R (or Revised NEO PI), and NEO PI-3, respectively. The revised inventories feature updated vocabulary that could be understood by adults of any education level, as well as children.

The inventories have both longer and shorter versions, with the full NEO PI-R consisting of 240 items and providing detailed facet scores. By contrast, the shorter NEO-FFI (NEO Five-Factor Inventory) comprised 60 items (12 per trait). The test was originally developed for use with adult men and women without overt psychopathology. It has also been found to be valid for use with children.
