NEO-PI-R • NEO Personality Inventory - Revised
Overview
The Test
The NEO PI-R is a measure of the five major domains of personality as well as the six facets that define each domain. Taken together, the five domain scales and thirty facet scales of the NEO PI-R facilitate a comprehensive and detailed assessment of normal adult personality. The NEO PI-R is recognized internationally as a gold standard for personality assessment. Today, reputable developers of personality tests for the occupational market will as a matter of course publish data on the relationship of their tests with the five factor model using one form or another of the NEO as the benchmark. The total amount of recent data from high level academic journals concerning the NEO PI-R underpins its quality.

Psychometric properties
The psychometric properties reported below relate to the UK adaptation of the NEO PI-R.
Reliability
Item analysis, (Cronbach’s Alpha) and factor analysis were carried out on a sample of 609 respondents in the UK Anglicization study. The UK results show close alignment with those from the US. The domain scales show internal reliabilities which range from .87 to .92. Facet scales show internal reliabilities ranging from .58 to .82.
Test retest reliabilities are all above .75
Validity
Validity data is extensive; for a full account the reader is referred to the Professional Manual (US edition), and reference lists are available from the publishers.
Duration
Test form Duration, ca. No. of items Standard 35.00 min 243 Durations are absolute, from start to end of the test process (incl. instruction phase etc).
