Internet-delivered Exposure-based Cognitive Behavior Therapy for Irritable Bowel Syndrome - a Cohort Effectiveness Study

Irritable Bowel Syndrome Clinical Trial

Official title:
The Effectiveness of Internet-delivered Exposure-based Cognitive Behavior Therapy for Irritable Bowel Syndrome - a Cohort Study

Clinical Trial Summary

The main purpose of the study is to investigate the clinical real-world effectiveness of a specific exposure based psychological treatment for irritable bowel syndrome (IBS). A secondary aim of the study is to find mediators of the treatment effect and thereby learn something about the working mechanism of the treatment.

Clinical Trial Description

IBS is a debilitating disorder with a prevalence of 10% world wide. For patients with severe forms of IBS where medication and other interventions have failed it can be useful to try psychological treatment. National Institute for Health and Care Excellence (NICE) guidelines recommend cognitive behavior therapy or hypnotherapy. Our research group at the Karolinska Institute in Stockholm has developed a cognitive behavioral treatment protocol for IBS. This treatment contains exposure therapy and mindfulness based exercises alongside psychoeducation. The treatment has been tested in four earlier randomized controlled trials (RCT) and produced large effect sizes compared to wait-list and moderate effect sizes compared to other active treatments or placebo. The present study aims to examine the effectiveness of the treatment protocol under real-world circumstances at a secondary-care unit in Stockholm. The Internet psychiatry Unit (IPSY) has been operative since 2007 and is run by Region Stockholm (i.e. the responsible authority for all publicly-funded healthcare in Stockholm). Patients with IBS have been treated at the clinic since 2015 and the treatment is delivered via an online treatment platform. The study is based on the clinics own data that has been collected for quality improvement reasons. Another aim of the study is to find out more about the working mechanisms behind the treatment by examining the weekly reports on behavioral avoidance and and anxiety that the patients file during treatment. All patients that have been treated at the clinic so far will be included in the study (N=319). Data has been collected between April 2015 and January 2022. The study has an approved ethical permit from the Swedish Authority for Ethical Approvals. The first hypothesis is that the treatment will be as effective in clinical routine care as it has been in earlier trials with a moderate to large effect-size from pre treatment to follow-up, six month after treatment. A second hypothesis is that the treatment effect is mediated by a change in behavioral avoidance that precedes symptomatic improvement. ;
