Sixteen clients afflicted with irritable bowel syndrome (IBS) were reassessed 1 year following completion of a multicomponent treatment package incorporating progressive muscle relaxation, thermal biofeedback, cognitive therapy, and IBS education. For the 14 patients who kept a 2-week symptom diary, significant reductions in ratings of abdominal pain and tenderness, diarrhea, and flatulence were obtained comparing pretreatment and follow-up symptom-diary ratings. Eleven of 14 clients were improved over pretreatment levels, 57% met the criteria for clinical improvement of at least a 50% reduction in major symptom scores, and all but 1 of 16 rated themselves as subjectively improved.
