Abstract

Objectives
This study was conducted to investigate the relationship between personality and decision making in the group of young male depression patients.
Methods
Eighty-four male depression patients were subjected to the following test: Beck’s Depression Inventory-II (BDI-II), and Beck’s Anxiety Inventory (BAI), Korean Wechsler Adult Intelligence Scale-IV (K-WAIS-IV), Minnesota Multiphasic Personality Inventory-2 (MMPI-2), Personality Assessment Inventory (PAI), Temperament Character Inventory-Revised Short version (TCI-RS), Delay Discounting Task (DDT), Game of Dice Task (GDT). Pearson’s correlation analysis was used to determine the association between DDT and GDT performance results and self-report examination. Multiple linear regression models were conducted to figure out the causal relationship between risky choice of GDT and the variables suspected of having a linear relationship. The collected data was analyzed using SPSS 21.
Results
PAI mania, borderline features, dominance and novelty seeking of TCI-RS were positively correlated with the number of risky choices of GDT. Full Scale Intelligence Quotient, BDI-II, BAI score had no significant correlation with DDT and GDT. There was also no correlation between DDT and GDT.
Conclusions
The results suggest that risk taking decision is related to personality traits such as novelty seeking, while inter-temporal choice is not related to personality aspects. It could be inferred that two different decision-making processes take place independently at different brain regions.
