In the current study, NEO Personality Inventory-revised (NEO PI-R), somatization PHQ-15 questionnaire, and Toronto Alexithymia Scale-20 were used. Data were analyzed using simultaneous regression analysis. In this study, there was a significant negative relationship between somatization and five factors of extraversion. Also, neuroticism and alexithymia had significant positive relationships with somatization. There wasnot any relationship between openness to experience and personality traits.
