Personal Profile System (DiSC)
June 2, 2006
Sixteen Personality-Factor Questionnaire (16 P-F)
August 1, 2006
The NEO inventories were developed by Dr. Paul Costa, Jr., and Dr. Robert McCrae to measure five broad dimensions of personality.
- Neuroticism (N)
- Extraversion (E)
- Openness (O)
- Agreeableness (A)
- Conscientiousness (C)
Note: These broad categories were based on analysis of trait adjectives collected over the years and included in research by theorists such as Cattell and Norman.
