Abstract

Objectives
The aim of this study was to investigate temperament and character associated with resilience in patients with bipolar disorder (BD).
Methods
A total of 55 outpatients diagnosed with BD according to the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (DSM-IV), and 55 healthy controls matched by age and sex with the BD group were recruited. All participants completed the Connor-Davidson Resilience Scale (CD-RISC) and Temperament and Character Inventory (TCI). Multiple linear regression analysis was performed by controlling for age, length of education, age of onset, number of depressive episodes, and number of hospitalizations to determine factors related to resilience. In addition, multiple regression analysis was performed using the interaction term to investigate whether temperament and character associated with resilience differed between the two groups.
Results
Patients with BD showed higher harm avoidance (p<0.001) and lower self-directedness (p<0.001) among the TCI dimensions compared to the control group. In multiple regression analysis, harm avoidance (β=-0.274, p=0.025) and self-directedness (β=0.431, p=0.002) were associated with resilience in patients with BD, while harm avoidance (β=-0.411, p=0.008), persistence (β=0.244, p=0.031), and cooperativeness (β=0.264, p=0.037) were associated with resilience in the control group. Self-directedness had a different relationship with resilience between the two groups (β=0.212, p=0.001).
Conclusions
The findings suggest that BD patients’ particular temperament and character are associated with resilience. Furthermore, temperament and character related to resilience differed between the BD group and the control group.
