Temperament and character inventory (TCI) and depression

Although several studies have assessed the relationships between the temperament dimensions of the Cloninger model of personality and depression, little is known about the role played by the character dimensions proposed by the seven-factor model of Cloninger in depression. In this study, the relationships between the Temperament and Character Inventory (TCI) and depression were examined in a sample of 40 major depressive patients and 40 healthy controls. Depressed patients exhibit higher harm avoidance and self-transcendence scores as well as lower self-directedness and cooperativeness scores as compared to healthy controls. However, the three other dimensions do not differ between depressive patients and controls. Among the depressive group, harm avoidance, self-directedness and cooperativeness dimensions are related to the severity of depression as assessed by the Hamilton scale. This study confirms the state dependence of the harm avoidance dimension and suggests a relationship between the character dimensions of the Cloninger model and depression.
