Purpose: This study was carried out to investigate the personality traits in the subjects with migraine and tension type headache and to evaluate the association between the headache characteristics and personality traits. Material and methods: 32 migraine and 37 chronic tension type headache subjects diagnosed according to the International Headache Society criteria and 35 healthy subjects were participated to this study. All subjects were evaluated by the Hacettepe Personality Inventory, the Beck Depression Inventory, and headache diary. Results: Migraine patients had the lower scores than other groups in emotional stability, neurotic traits and family relationship subscales, and personal and general harmony scale of the Hacettepe Personality Inventory (p<0.05). The depression score of migraine patients was higher than the other groups (p<0.05). There were negative linear correlation between the emotional stability and headache frequency (r=-0.398, p=0.032), and between the family relationship and headache duration (r=-0.436, p=0.018). Conclusion: The results of this study suggest that migraine subjects have different personality traits. In contrast, the personality traits of chronic tension type headache patients are similar to those of healthy subjects.
