RESUMEN
OBJECTIVE: The aim was to determine how personality of major depressive disorder (MDD) patients is different from that of bipolar II disorder (BIID) patients. METHODS: In this cross-sectional study, two groups of patients with MDD (47 patients) and BIID (45 patients) between 18 and 55 years old were included and compared. The research instrument that subjects answered to was Temperament and Characteristic Inventory-125-R. RESULTS: Among temperament dimensions, novelty seeking, and reward-dependently in contrast with other traits such as harm avoidance and persistence showed a significant difference between the two studied groups. Among characteristic dimensions, self-direction and self-transcendence demonstrated a significant difference between the two groups (p < 0.005). CONCLUSION: Patients suffering from BIID are sensation seeker and are motivated by stimulates more often than MDD patients are. They feel euphoria more and, find the world more stimulating.
RESUMEN
OBJECTIVE: The aim of this study was to compare the clinical temperaments and characters of Iranian patients with Major Depressive Disorder (MDD) with healthy controls. METHOD: The study participants included 47 outpatients with Major Depressive Disorder (MDD) and 120 normal controls with no psychiatric disorders. Sampling method was convenience. The MDD patients were diagnosed as MDD by a psychiatrist using the Persian structured clinical interview for axis I disorders (SCID-I), and they completed at least 8 weeks of antidepressant treatment. All the patients filled out the Persian version of the Temperament and Character Inventory (TCI). Data were analyzed using SPSS version 17, Chi square, T test and Multiple Regression. The level of significance was set at 5%. RESULTS: The present study demonstrates a link between depression and lower persistence (p≤0.001), self-directedness (p≤0.001) and cooperativeness (p≤0.001) scores. A negative correlation between age and Harm Avoidance (p≤0.001) was observed in both groups. CONCLUSION: Lower scores of persistence (P), self-directedness (SD) and cooperativeness (CO) were observed in patients with depression more than controls even in the remission phase which could indicate a relationship between these traits and depression.
