Personality characteristics and irritable bowel syndrome in Shiraz, southern Iran.
OBJECTIVE
Irritable bowel syndrome (IBS) is the most common functional gastrointestinal disorder, and its definite etiology is still unclear. It has been shown that personality characteristics can affect the disease presentation and attitude of patient toward symptoms. This study was undertaken to evaluate the personality characteristics in patients with IBS in Shiraz, southern Iran.


METHODS
In a cross-sectional study, the personality characteristics of 60 patients with IBS and 55 healthy persons were compared using Minnesota II Multiphasic Personality Inventory (MMPI-2). The cases were selected from patients who were referred to the Mottahari clinic affiliated to the Shiraz University of Medical Sciences.


RESULTS
The patients recorded the highest scores on the hypochondriasis and psychoasthenia scales. The scores of the patient on the scales of lie, infrequency, hypochondriasis, depression and hysteria showed significant elevation in comparison to those of the control group. Furthermore, the scores on clinical scales in male subjects were higher for psychopathic-deviate, paranoia and social introversion scales in comparison to the males in the control group. Female subjects recorded lower scores on the social introversion scale in comparison to the females in the control group. Male subjects also recorded a higher score on the psychopathic-deviate, paranoia, psychoasthenia and social introversion scales in comparison to females. Female subjects had a relatively higher score on the masculinity/feminity scale. Based on the clinical interview using DMS-IV criteria, the most prevalent symptoms were anxiety and depression in patients with IBS.


CONCLUSIONS
Due to the high prevalence of anxiety and depression in patients with IBS, psychotherapy and pharmacotherapy of these patients is recommended.
