Acceptance and commitment therapy for the treatment of irritable bowel syndrome and inflammatory bowel disease: a narrative review.

BACKGROUND AND

OBJECTIVE

Cognitive behavioral therapy (CBT) is a common treatment modality for patients with irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD). CBT may not be a good fit for all patients and some may instead benefit from an acceptance and commitment therapy (ACT) approach. This narrative review presents evidence for the use of ACT in adult patients with IBS or IBD. The authors also suggest instances in which patients with IBS or IBD may benefit from ACT and discuss future directions of research.

METHODS

Between August 2023 and January 2024, databases such as Google Scholar, institutional libraries, and PubMed were used to review the literature on ACT in patients with IBS and IBD. A variety of search terms were included. Non-English, pediatric, and studies that did not employ a full ACT protocol were excluded.

KEY CONTENT AND FINDINGS: ACT for IBS studies typically utilized a self-help book or a one-day workshop intervention, with results indicating reductions in IBS and mood symptoms and improvements in quality of life. Within IBD, three randomized controlled trials (RCTs) tested the impact of ACT, two of which found reductions in stress, depression, and anxiety symptoms.

CONCLUSIONS

Despite the limited number of studies testing a full ACT protocol in patient populations with IBS or IBD, results indicate potential efficacy in managing not only symptoms, but also facets of quality of life. Future studies should utilize robust experimental designs and comprehensively test the effectiveness of ACT in IBS and IBD patient populations with both process and outcome measures.
