Clinical Trial: Assessing Cognitive Behavioral Therapy in Irritable Bowel Syndrome University of Southampton, UK, 2015

The University of Southampton, in collaboration with Kings College, London, has an ongoing multi-center clinical trial begun in 2013 and expected to be published in 2018 comparing the clinical and cost effectiveness of therapist cognitive behavioral therapy and lower intensity web-based cognitive behavioral therapy for people with refractory irritable bowel syndrome (IBS).

A total of 495 volunteers with IBS have been or will be recruited from primary and secondary care in Southampton and London and randomized into one of the two groups. The therapist CBT group receives 6 one-hour telephone sessions with a therapist over a period of 9 weeks, plus two one-hour followup calls at 4 months and 8 months following treatment for a total of 8 hours contact time with the therapist.  The lower intensity web-based CBT group receives a web-based self-management program plus 3 half-hour telephone sessions with a therapist over 9 weeks, plus two half-hour followup up calls at 4 months and 8 months following treatment for a total of 2 1/2 hours contact time with a therapist. The original listing can be found here on the University of Southampton website.  ACTIB Cognitive Behavioral Therapy Study, Southampton For further details or to volunteer, please contact Gilly O’Reilly, Trial Manager, at


While IBS Impact attempts to highlight a diversity of available opportunities, this is not intended as an exhaustive resource. Previous posts on open clinical trials for IBS can be found by clicking the clinical trials category in the blog archives on the upper right sidebar of this blog. We also have a page for IBS studies on the main IBS Impact site. Because studies stop accepting new volunteers or are completed over time, please check the post date on this blog, or the last update date on studies page, to verify that the study you are interested in is relatively recent rather than from a few years ago. Depending on how you accessed this blog, the post date will appear either at the top or at the bottom of the post, and is occasionally included in the post title. On the studies page on the main site, the date of the last update is at both the top and the bottom of the page. The research and links pages and the July 26, 2011 post provide additional general resources.

We welcome researchers affiliated with academic, medical or pharmaceutical entities, or reputable organizations representing IBS or related or commonly overlapping conditions, to contact us directly with additional studies they wish to be considered for posting or if an existing listing needs to be updated. Contact links for the founder/listowner and the webmaster can be found on the home page of the main IBS Impact website.
