Temperament and Character Inventory
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
- 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.
