A significant minority of people with irritable bowel syndrome (IBS) respond rapidly to cognitive behaviour therapy and these benefits seem to be long-lasting. Researchers from the University at Buffalo, in New York, studied 71 people with IBS who received smaller or larger 'doses' of cognitive behaviour therapy (CBT). 30% of the sample could be classified as 'rapid responders' of whom 90-95% were still better after three months. Although the rapid responders had more symptoms at the start of the study they achieved a more substantial and sustained symptom reduction than non-rapid responders. Both 'doses' of CBT had comparable rates of rapid responders.
