NEO Personality Inventory-Revised (NEO PI-R)

The NEO PI-R is restricted to psychologist use only.

The NEO PI-R provides a comprehensive and detailed assessment of adult personality based on the Five-Factor Model (FFM) of personality. The FFM is taxonomy of personality traits in terms of five broad dimensions (the "BIG FIVE"): Neuroticism, Extraversion, Openness to Experience, Agreeableness, and Conscientiousness. It offers a conceptually useful framework for understanding the structure and systems of Axis II personality disorders.

In only 35-45 minutes, the NEO PI-R provides a systematic assessment of emotional, interpersonal, experiential, attitudinal, and motivational styles. The NEO PI-R is validated against other personality inventories, as well as projective assessments.

The NEO PI-R is a concise measure of the five major domains of personality, as well as the six traits or facets that define each domain. Taken together, the five domain scales and 30 facet scales of the NEO PI-R facilitate a comprehensive and detailed assessment of normal adult personality. The NEO PI-R has useful applications in counselling, clinical psychology, psychiatry, behavioural medicine and health psychology, vocational counselling and industrial/organizational psychology, and educational and personality research.

  • Neuroticism (N) - refers to the chronic level of emotional adjustment and instability. High N identifies individuals who are prone to psychological distress.
  • Extraversion (E) - refers to the quantity and intensity of preferred interpersonal interactions, activity level, need for stimulation, and capacity for joy. High E identifies individuals who tend to be sociable, active, talkative, person oriented, optimistic, fun loving, and affectionate.
  • Openness to Experience (O) - refers to the active seeking and appreciation of experiences for their own sake. High O identifies individuals who are curious, imaginative, and willing to entertain novel ideas and unconventional values.
  • Agreeableness (A) - refers to the kinds of interactions an individual prefers along a continuum from compassion to antagonism. High A identifies individuals who tend to be soft-hearted, good natured, trusting, helpful, forgiving, and altruistic.
  • Conscientiousness (C) - assesses the degree of organization, persistence, control, motivation in goal-directed behaviour. High C identifies individuals who tend to be organized, reliable, hard-working, self-directed, punctual, scrupulous, ambitious, and persevering.


The NEO PI-R is self-administered and is available in two parallel versions. Each version contains 240 items and 3 validity items, and requires a 6th grade reading level.

  • Form S, designed for self-reports, is appropriate for use with adult men and women, including individuals of college age.
  • Form R, designed for observer reports, is written in the third person for peer, spouse, or expert ratings. Use as an alternative measure or as a supplement to self-reports from adult clients.
  • Each item is rated on a 5-point Likert scale.
  • Internal consistency coefficients for both Forms R and S range from .86-.95 for domain scales and from .56-.90 for facet scales.
  • The NEO PI-R is validated against other personality inventories as well as projective techniques.
