Purpose: Designed to measure five major dimensions or domains of normal adult personality.

Population: Ages 17 and older.

Scores: 30 facet scores and 5 domain scores.

Time: (30-40) minutes.

Authors: Paul T. Costa, Jr. and Robert R. McCrae.

Description: The NEO-PI-R is the most recent version of Costa and McCrae’s instrument to assess normal adult personality using the five-factor model taxonomy of personality. It is one of the few commercially available test based on this model.

Scoring: The NEO-P-R assesses five major domains of personality: Neuroticism (N), Extroversion (E), Openness to Experience (O), Agreeableness (A), and Conscientiousness (C), each represented by six lower level facet scale scores. It is available in three formats: self-report and observer-report versions and the NEO-FFI, a 60-item short form of the instrument.

Reliability: Domain level reliabilities range from .86 to .95 for both the self and observer rating forms of this instrument. Facet level reliabilities are good ranging from .56 to .90 for both self- and observer-report forms of the NEO-PI-R. Short-term test-retest reliability has been found with the NEO-FFI and the NEO-PI-R. Long-term test-retest reliability has been shown for the N, E, and O domains for the previous version of this instrument.

Validity: There is strong consensual validity between self, peer, and spouse reports of the test. Construct, convergent, and divergent validity evidence for the scales has been collected by Costa and McCrae. NEO-PI-R scales correlated with analogous scales from other instruments.

Norms: Norms are based on a sample of 1,000 subjects (500 males, 500 females) selected from three large scale studies of the NEO-PI-R. The normative sample was stratified to match 1995 U.S. Census projections for age, gender, and race. Separate norms are also provided for college-aged samples.

Suggested Uses: It is recommended that these scales are useful tools for personality assessment and may provide a useful bridge between basic research in personality psychology and applied psychology.
