Plain English summary of protocol

Background and study aims
Hypnotherapy has been shown to work as a treatment of irritable bowel syndrome (IBS). However, it has not been widely adopted by healthcare providers and this is probably because it is very time consuming and no set guidelines exist. It seems likely that hypnotherapy might be used more readily if it could be delivered over a shorter period of time and the technique better described so that therapists would find it easy to use the same methods.
This study aims to establish whether a short course of well described hypnotherapy works as well as conventional hypnotherapy where the sessions can be rather long and the content is dependent on the style of the therapist.

Who can participate?
The trial will be open to men and women between the ages of 18 and 65 who have irritable bowel syndrome without any other illnesses that could interfere with treatment.

What does the study involve?
A short course of six sessions of completely scripted hypnotherapy (like having a manual) will be compared with conventional hypnotherapy which involves twelve sessions of unscripted treatment.

What are the possible benefits and risks of participating?
All patients will receive one or other of the forms of hypnotherapy and should, therefore, experience benefit from the treatment. However, if the patients receiving the short form of treatment are seen to not do so well, they will be offered further treatment sessions in order to try and improve them further. Hypnotherapy has no side effects and never makes irritable bowel worse.
