NEO-PI Traits and Facets

NEO stands for Neuroticism, Extraversion, and Openness to Experience - three of the Big Five or Five-Factor Model (FFM) traits. The NEO-PI (Personality Inventory) incorporated the two additional Big Five traits of Agreeableness and Conscientiousness. In addition to the five traits, the NEO-PI also measures six sub-traits or facets of each Big Five trait.

    Facets: Anxiety, Anger, Depression, Self-Consciousness, Immoderation, Vulnerability
  • Trait: Openness to Experience
