 Development of a web-based self-management CBT program for IBS developed in partnership with patients has the potential to benefit large numbers of patients with low cost to the NHS. CBT has been shown to be of benefit for IBS but its availability is limited due to the high cost and therapist time required for face-to-face CBT. A website can be accessed at a time and place convenient to the patient and the CBT program undertaken at a pace determined by patient needs. The website could be used as a long term support for self-management.
