• Neo Pi R Personality Test

The NEO PI-R test is an untimed test, which is usually completed within a 90-minute timeframe. The test has 240 questions designed to measure the candidate’s Big-Five personality traits. A second, and shorter exam is known as the NEO Five-Factor Inventory, otherwise called the NEO-FFI has 60 questions. 1990), or “Big Five. ” e NEO-PI-R and a slightly simpli ed NEO-PI-3 (McCrae & Costa, 2010; McCrae, Costa, & Martin, 2005) consist of 240 items that assess 30 speci c tra its, which in turn de.

A great deal has already been written about the NEO, even if you don’t count the amazing number of articles authored by its creators, Paul T. Costa, Jr. and Robert (Jeff) R. McCrae. In fact, so much has been said that there doesn’t seem much point in providing another drawn-out discussion when a short summary will suffice.

The NEO was originally created as a 3 factor model assessing Neuroticism, Extraversion and Openness. Following the input from many other personality researchers, a revision of the NEO – the NEO-PI-R (that is, “Personality Inventory – Revised”) was published in the late 1980s, around the same time that Lew Goldberg published the Big Five Factor Markers. The most prominent revision to the original version was the addition of two new factors – Agreeableness and Conscientiousness. Costa and McCrae have specified in several publications that the NEO-PI-R is merely a measure of their broader Five Factor Model (FFM) of personality. They tend to refer to the factors of the NEO as “domains” – multifaceted collections of tendencies that can be grouped in a variety of ways.[1] They use the term “facet” to refer to the traits that comprise each of these domains (they have identified six facets in each), and they have more recently written about the “nuances” which lie still further below the facets.

The NEO-PI-R differs from the Big Five Factor Markers, in part because the latter was more strictly derived from the psycholexical tradition that began with Galton and later advanced by Allport and Odbert, Cattell, Tupes and Christal, Norman, Digman, and others. Both the NEO and the Big Five contain five broad and similarly operationalized factors but they’re not identical. Emotional Stability (Big Five) and Neuroticism (the NEO) contain similar content but are named in opposite directions. Intellect (Big Five) and Openness (NEO) are not only named differently but the latter contains relatively little “intellectual” content. As mentioned above, the five factors of the NEO can also be scored at a more narrow facet level. The table below shows the six facets that are nested in each factor.

Versions of the NEO-PI-R are available in several different lengths (from 60 to 240 items) and in two forms (self-reports and observer-reports). Observer report forms of the NEO-PI-R are written in the third person for ratings given by those who are close to the individual being assessed (such as a peer or spouse). Answers for both the self-report and observer-report take the form of a five-point Likert scale ranging from 1 (disagree strongly) to 5 (agree strongly).
