In psychology, trait (or dispositional) theory is an approach to the abstraction and understanding of human behavioural patterns. It involves breaking down attributes of personality into a finite list of traits. The two most popular models of trait theory are the three-factor Eysenck Personality Questionnaire (EPQ) model and the five-factor OCEAN model.
