Predicting IBS responders to hynotherapy
Approximately two-thirds of patients with irritable bowel syndrome (IBS) respond well to hypnotherapy.
Researchers at the University of Manchester, in the UK, assessed whether a therapeutic response to hypnosis could be predicted by relating mood to a positive, neutral or negative color.
First, the details.
- 156 consecutive IBS patients were studied.
- Before and after treatment, patients were asked to relate their mood to a color on the Manchester Color Wheel (MCW), as well as completing a battery of other measures including the Hospital Anxiety and Depression (HAD) Scale, and the Tellegen Absorption Scale (TAS) which is a measure of the responsiveness to hypnosis.
And, the results.
- For patients with a positive mood color the odds of responding to hypnotherapy were 9 times higher than for those choosing either a neutral or negative color or no color at all — a significant difference.
- A high TAS score and the presence of HAD anxiety also had good predictive value with these markers and a positive mood color being independent of each other — significant differences.
- These factors combined gave a stronger prediction of outcome.
- Twice as many responders (78%) had a positive mood color or were anxious or had a high TAS score compared with 43%) without these factors — a significant difference.
The bottom line?
The authors concluded, “A positive mood color, especially when combined with HAD anxiety and a high TAS score, predict a good response to hypnotherapy.”
In an earlier article, Prof. Whorwell, also a researcher in this study, reported that with a “success-rate of about 70%” hypnotherapy, although labor-intensive, could be a medically and cost effect treatment compared to new drugs.
