Abstract

BACKGROUND: There is a need for safe and effective IBS treatments that provide immediate and sustained improvement of IBS symptoms, particularly among more severe patients. The aim was to assess long-term clinical response of cognitive behavioral therapy (CBT) with reference to IBS education. METHODS: A total of 436 Rome III-diagnosed IBS patients (80% F, M age = 41 years) were randomized to: 4 session home-based CBT (minimal contact (MC-CBT)), 10 session clinic-based CBT (standard (S-CBT)), or 4 session IBS education (EDU). Follow-up occurred at 2 weeks and 3, 6, 9, and 12 months following treatment completion. Treatment response was based a priori on the Clinical Global Improvement Scale (global IBS symptom improvement) and IBS Symptom Severity Scale (IBS-SSS). RESULTS: Post-treatment CGI gains were generally maintained by MC-CBT patients at quarterly intervals through 12-month follow-up with negligible decay. For MC-CBT and S-CBT, 39 and 33% of respondents maintained treatment response at every follow-up assessment. The corresponding percent for EDU was 19%, which was significantly lower ( p < 0.05) than for the CBT groups. On the IBS-SSS, therapeutic gains also showed a pattern of maintenance with trends towards increased efficacy over time in all conditions, with the mean unit reductions between baseline and follows-up being approximately −76 at immediate and approximately −94 at 12 months (−50 = clinically significant). CONCLUSIONS: For treatment-refractory IBS patients, home- and clinic-based CBT resulted in substantial and enduring relief of multiple IBS symptoms that generally extended to 12-month post treatment.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
