Abstract
AIM: The present study presents a new combined approach for the treatment of irritable bowel syndrome (IBS), in which the effect of Cognitive Behavioral Therapy (CBT) based on exposure to awareness and emotional expression on patients' symptoms is examined. BACKGROUND: IBS is one of the most common functional gastrointestinal diseases where psychological distress is an integral part of its presentation. METHODS: We performed a clinical trial study on 30 patients with IBS. They were divided into two groups receiving the intervention and waiting list control. All patients were evaluated by IBS quality of life scale, IBS severity score, hospital anxiety and depression scale and visceral sensitivity index in three stages: pre-test, pre-test, and one-month follow-up. Our treatment program for the intervention group (n=15) included 10 group sessions, every week for 90 minutes, based on an exposure-based cognitive behavioral therapy protocol. Also, they underwent three 90-minute sessions of an emotional expression and awareness training program. RESULTS: The mean age of the participants was 31.0±8.77 years old. No previous history of substance addiction, psychiatric, or neurologic diseases was seen. Twenty participants (66.7%) were single, twenty-three participants (76.7%) had a university degree, and 9 participants were unemployed. No significant difference was seen between the case and control groups regarding education, occupation, and marital status. All pairwise comparisons of pre-test, post-test, and follow-up IBS-QOL scores were significant between the two groups (p<0.001). Similarly, pre- and post-, and pre- and follow-up test differences for IBS-SSS and VSI were significantly different between the two groups. CONCLUSION: Exposure-based CBT combined with emotional expression and awareness training could alleviate the IBS symptoms, reduce visceral sensitivity, and improve quality of life.
