WHAT IS THE NEO

The revised NEO Personality Inventory (NEO PI-R) is the standard questionnaire measure of the five-factor measure of adult personality. The NEO PI-R provides a systematic assessment of emotional, interpersonal, experiential, attitudinal, and motivational styles. The NEO PI-R consists of 243 items, including validity items, takes approximately 35-45 minutes to administer, and can be administered to students and adults with a reading level of 6th grade and above.The NEO PI-R is a concise measure of the 5 major domains of personality, as well as the 6 traits  or facets that define each domain. Taken together, the 5 domains and the 30 facet scales of the NEO PI-R, including the scales for the Agreeableness and the Conscientiousness domains, facilitate a comprehensive and detailed assessment of normal adult personality. The 5 domain scales (often referred to as OCEAN) and their facet scales are:

The NEO PI-R is available in two parallel versions. A Form S designed for self-reports and a Form R for observer reports. Much international research and a limited amount of South African research has been published on this instrument. Reported internal consistency coefficients ranging from 0.86 - 0.95 for the domain scales and from 0.56 - 0.90 for the facet scales, have been reported. The NEO PI-R has shown good convergent validity with other personality inventories, as well as projective techniques. The NEO PI-TR has been translated into more than 20 languages so far. There is also a four factor version of the NEO (NEO-4) which excludes the Neuroticism domain.
