Personality traits and psychological complaints under patients suffering from headaches.

Abstract

Background and purpose:

Although headaches are often comorbid with psychological symptoms, the underlying psychological processes, e.g. the role of personality dimensions as headache determinants remains unclear. Studies found associations between headaches and various personality traits; according to the Big Five model of personality, persons suffering from headaches exhibit a higher rate in neuroticism, while a lower rate in extraversion, openness to experiences and positive emotions. This is the first study to clarify the associations among duration, intensity, and frequency of headaches and personality dimensions. Through this study we could get into the personality dimensions in the background of pain experience and that which personality dimensions bear a part in the behaviour of the persons, who suffered from headache, but do not seek treatment through this complaint. 

.

Methods:

Treated (Group1) and untreated (Group2) headache patients and healthy controls (Group3) were investigated (total of 360 participants). The main headache components of intensity, duration, and frequency were used as dependent variables with personality dimensions in the Big Five concept investigated by the NEO-PI-R Personality Inventory.

.

Results:

Employing multiple regression analysis, facets of personality described 14.7% of headache intensity, 10.9 % of duration, and 18.7 % of frequency variance. Group1 and Group2 reached significantly higher values on the dimension of anxiety, depression, and vulnerability to stress than Group3. Group1 showed a significantly higher value on trust personality dimension than Group3 and Group2. Group3 exhibited a significantly higher value in the trust dimension than Group2. Concerning vulnerability to stress, the highest value was yielded by the “treated and suffering from headaches” group and there was a significant difference also with the “untreated and suffering from headaches” group and with the control group. In this dimension, the “untreated and suffering from headaches” group’s point value was significantly higher than the control group’s (p<0.01, U=-4.501).

.

Conclusion:

Our study demonstrates that the three headache components are not independent from personality traits, and personality traits may interact with treatment seeking behavior even in the presence of significant headache complaints. The role of the personality traits are significant in the intensity, duration and frequency of headaches.
