"Personality" is one of the classic chapter headings in the field of psychology, and yet is surprisingly difficult to define. It is used so widely, and in such differing ways, that any singular definition must either be confusingly inclusive or misleadingly specific. Perhaps a definitional approach to personality should be avoided altogether, rather personality should be understood in relation to the schools of thought which characterize it (trait theories, psychoanalytic theories and so on). In its broadest sense personality can be said to be the sum total of all the behavioral and mental characteristics by means of which an individual is recognized as being unique.

The Five-Factor or "Big Five" model of personality is arguably the most popular way of describing and conceptualising adult personality. The acronym OCEAN is sometimes used to help remember the five dimensions (Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism). This way of describing and understanding personality has evolved from the broader trait approach, and shares common ground with other approaches, such as Eysenck's PEN model (which incorporates Psychoticism, Extraversion and Neuroticism). The strongest proponents of the five factor model are Paul Costa and Robert McCrae, and the measurement of the "Big Five" has become virtually synonymous with the use of the NEO-PI-R questionnaire.
Additions to this category should relate directly and specifically to the five-factor model of personality.
