The Temperament and Character Inventory (TCI) is an inventory for personality traits devised by Cloninger et al.It is closely related to and an outgrowth of the Tridimensional Personality Questionnaire (TPQ),and it has also been related to the dimensions of personality in Zuckerman's alternative five and Eysenck's models and those of the five factor model.
TCI operates with seven dimensions of personality traits: four so-called temperaments
In psychology, a facet is a specific and unique aspect of a broader personality trait. Both the concept and the term "facet" were introduced by Paul Costa and Robert McCrae in the first edition of the NEO-Personality Inventory (NEO-PI) Manual. Facets were originally elaborated only for the neuroticism, openness to experience, and extraversion traits; Costa and McCrae introduced facet scales for the agreeableness and conscientiousness traits in the Revised NEO-PI (NEO PI-R). Each of the Big Five personality traits in the five factor model contains six facets, each of which is measured with a separate scale. The use of facets and facet scales has since expanded beyond the NEO PI-R, with alternative facet and domain structures derived from other models of personality. Examples include the HEXACO model of personality structure, psycholexical studies, circumplex models (e.g., Goldberg's Abridged Big-Five Dimensional Circumplex), the Multidimensional Personality Questionnaire (MPQ), and the California Psychological Inventory.
