IPIP-NEO-120 Inventory

IPIP equivalent to NEO-PI-R

The Revised NEO Personality Inventory, created by Paul T. Costa, Jr. and Robert R. McCrae, is one of the most famous inventories of the Five Factor Model (FFM) and is widely used by professionals to measure interpersonal relationships, emotional behavior, and motivational factors of a person.

This test is the online version of Dr. John A. Johnson's 120-question version (2014) of IPIP NEO Inventory, which correlates strongly with scales from original commercial inventories.

The IPIP equivalent to NEO-PI-R is a valid tool for assessing Big Five personality traits: openness to experience, conscientiousness, extraversion, agreeableness, and neuroticism. In addition, 6 specific personality facets are evaluated for each scale.

The Five Factor Model of Personality

Many of the leading psychologists confirm that the five factor model most qualitatively reflects the most important individual differences in personality traits.

Despite this, the five-factor model is also often criticized. Some scientists are concerned that each trait is too broad to provide a sufficiently complete understanding of the human personality.

There is no doubt that this model played an important role in the development of the discipline of personality psychology, led to the creation of many additional studies, and caused a lot of discussion in the scientific community, which continues to this day.


Read each statement carefully and define how accurately each statement describes you. Describe yourself as you generally are now, not as you wish to be in the future, and be honest to get the most correct results.
