ABSTRACT

Quality of life is a main outcome in psychosomatic disorders. Several psychological factors are mentioned for predicting the quality of life in patients who suffer from irritable bowel syndrome [IBS]. The aim of this study is to determine the relationship between type D personality and quality of life in patients with IBS. This study enrolled 90 [52 women] IBS patients who referred to the gastroenterology clinics of Imam Khomeini and Laleh hospitals from September to December 2012. We used the Type D Personality and IBS Quality of Life questionnaires to evaluate patients. Data were analyzed by Pearson correlation and multi-variable regression models. Overall, 61% of patients were H. pylori positive. The mean anti-Thyroid peroxidase level in the H. pylori positive group We observed a relationship between type D personality and quality of life in patients with IBS [r=0.504, p<0.01]. The results showed a 26% variation in quality of life predicted by type D personality [p<0.01, R[2]=0.26]. According to the results, type D personality is one of the predictors of quality of life in patients with IBS. Therefore, it is important to consider psychological factors when choosing the appropriate treatment for IBS patients.
