neo personality inventory

WHAT KIND OF TEST?

The Revised NEO-Personality Inventory (NEO-PI-R) (Costa & McCrae, 1992) is self-report measure of personality features that comprise an influential model of personality known as the Five-Factor Model (FFM) (Goldberg, 1993).

The NEO-PI-R consists of 240 items (8 items for each of the 30 facets or 48 items for each of the five domains).

THERE DIFFERENT VERSIONS OF NEO-PI

Form S is the self-report form with items answered on a 5-point Likert scale from “strongly disagree” to “strongly agree.”

Form R is a companion instrument for observer ratings, with items written in the third person, for use by spouse, peer, or expert ratings (McCrae, 1982).

An abbreviated version - 60 items, and yielding scores for the five domains only (Costa & McCrae, 1989).

Like most commercially published personality inventories, the NEO-PI-R uses a reusable test booklet, and a separate answer sheet. The NEO-PI-R is intended for use throughout the adult age range.

administering:

• can be administered to one person or many
• about 20-30 mins.
• can computer administered, scored & interpreted
• can be machine scored or hand-scored

WHAT ARE THE CHARACTERISTICS MEASURED?

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.

characteristics measured:

• Neuroticism
• Extraversion
• Openness
• Agreeablenes

RELIABILITY & VALIDITY

NEO-PI-R scores show excellent levels of both internal consistency and test-retest reliability.
Test-retest reliability has been impressively high over time periods as long as 6 years.

reliability was dependent on the specific NEO dimension – specifically Agreeableness scores were the weakest

lacks in validity scale (or set of scales) to evaluate respondents’ test-taking approaches.
The NEO-PI-R has 3 individual items that assess the validity of responses.

HOW IS IT SCORED?

1. Raw scores are first calculated for all 30 facet scales and 5 domain scales.

2. These scores are then plotted on profile sheets that are separately normed for men and women. Plotting converts the raw scores into T scores. However, T scores are then used to calculate domain factor scores.

3. Each factor score involves adding (or subtracting) some 30 components (the facet scores)
