Developed as a measure of the Five Factor Model, the NEO Personality Inventory-Revised uses these five dimensions – emotional, interpersonal, experiential, attitudinal, and motivational styles – to evaluate adult personality. A purpose for this instrument is a resource for such professionals as counselors, psychiatrists, psychologists, doctors, vocational counselors, and educators.
The NEO PI-R has to different forms: Forms S and Form R. In each, participants are asked to respond to 240 items using a 5-point scale. Approximately 30 to 40 minutes is required for completion.

Reliability and Validity
For the Revised NEO Personality Inventory, the test manual provides good support for both reliability and validity. Internal consistency coefficients were calculated at 0.86 to 0.95 for both the forms (self and observer). While only three of the subtests had good long-term test-retest reliability (Neuroticism, Extraversion, Openness to Experience), all of them had high short-term test-retest reliability. The authors and others give evidence for construct, convergent, and divergent validity. Some of this evidence was provided through correlations with the Peyers-Briggs Type Indicator, Personality Research Form, Minnesota Multiphasic Personality Inventory, and the Self Directed Search.
