Personality traits as risk factors of depression and anxiety among Japanese students

Abstract

The aim of this study is to examine the effects of personality (temperament and character) on specific depression and specific anxiety. A total of 541 Japanese undergraduates were investigated by using the Temperament and Character Inventory (TCI) and the Hospital Anxiety and Depression (HAD) scale. Hierarchical multiple regression analyses demonstrated that specific depression was predicted by lower Reward‐Dependence, Persistence, Self‐Directedness, Cooperativeness, and Self‐Transcendence; specific anxiety was predicted by higher Novelty‐Seeking, Harm‐Avoidance, Persistence, and Self‐Transcendence, and lower Self‐Directedness. Immaturity of Self‐Directedness is a risk factor for negative affectivity. Immaturity of all character dimensions is a risk factor for specific depression. The relationship between Harm‐Avoidance and depression in previous studies may be linked partly to somatic symptoms that were deliberately eliminated in the HAD scale. © 2005 Wiley Periodicals, Inc.
