Temperament and Character Inventory
From Wikipedia, the free encyclopedia
The Temperament and Character Inventory (TCI) is an inventory for personality traits devised by Cloninger et al.[1] 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[2] and those of the five factor model.[3]
TCI operates with seven dimensions of personality traits: four so-called temperaments[4]
- Novelty seeking (NS)
- Harm avoidance (HA)
- Reward dependence (RD)
- Persistence (PS)
and three so-called characters
- Self-directedness (SD)
- Cooperativeness (CO)
- Self-transcendence (ST)
Each of these traits has a varying number of subscales. The dimensions are determined from a 240-item questionnaire.
The TCI is based on a psychobiological model that attempts to explain the underlying causes of individual differences in personality traits.[5]
