Personality traits provide distal explanations for behavior and are compatible with personality development, useful in clinical applications, and intrinsically interesting. They must, however, be understood in the context of a broader system of personality functioning. One of the recurring challenges to personality psychology has been the classification of personality traits into a meaningful system. Introduced in the 1980s, the Five-Factor Model (FFM) is a comprehensive and universal model applicable to psychiatric as well as normal samples. The NEO Inventories are operationalizations of the FFM, and offer computer administration and interpretation. They are available in a number of languages and use a novel approach to protocol validity. Research using the NEO Inventories has led to a reconceptualization of the importance of the person in the social sciences, and may be the basis for a revolutionary new approach to the diagnosis of personality disorders.
