There is controversy regarding the effectiveness or ineffectiveness of ACT in reducing severity of IBS symptoms, improving quality of life, and changing value-related behaviors.
“In general, there is controversy regarding the effectiveness [91,92], or ineffectiveness [111], of ACT in reducing the severity of IBS symptoms, and regarding its capacity to improve the quality of life of IBS patients, and change value-related behaviors [91,92].”
From Effectiveness of acceptance and commitment therapy in central pain sensitization syndromes: A systematic review (2021) · cites this paper as [92]
The Treatment effects and Discussion sections report reduced IBS symptom severity after ACT-based bibliotherapy, but no improvement in quality of life, activity engagement, or avoidance behaviours. The Introduction reports improvements in those latter outcomes from an earlier ACT study, so this paper supports a mixed picture, not improvement across all three outcomes in its own trial. Page numbers are unavailable in our copy. (LLM, conf=0.88)
Experimental — accuracy not yet measuredACT does not modify post fulfilment of diagnostic criteria in IBS patients.
“modify post fulfilment of diagnostic criteria in IBS patients [92]”
From Effectiveness of acceptance and commitment therapy in central pain sensitization syndromes: A systematic review (2021) · cites this paper as [92]
The Treatment effects section reports no statistically significant change in whether participants met IBS diagnostic criteria after ACT-based bibliotherapy. But four participants (9%) no longer met the criteria at follow-up, so the categorical claim that ACT does not modify diagnostic status overstates the finding from this trial. (LLM, conf=0.86)
Experimental — accuracy not yet measuredPrevious studies have shown that ACT for IBS patients is effective in reducing symptom severity and improving QOL.
“First, previous studies have shown that ACT for IBS patients is effective in reducing the severity of symptoms and improving QOL (Ferreira, Gillanders, Morris, & Eugenicos, 2017;Gillanders, Ferreira, Angioni, Carvalho, & Eugenicos, 2017).”
From Effectiveness of acceptance and commitment therapy for irritable bowel syndrome non-patients: A pilot randomized waiting list controlled trial (2020) · cites this paper as Gillanders et al., 2017
The Treatment effects section reports improved IBS symptom severity but no improvement in the impact of IBS on quality of life in this bibliotherapy trial. The Introduction reports that an earlier ACT trial improved both symptoms and quality of life, but that does not establish a quality-of-life improvement in this source's own trial. (LLM, conf=0.90)
Experimental — accuracy not yet measuredThese findings are in line with evidence from previous studies supporting the associations between PF processes and aspects of daily functioning in GI conditions.
“On the positive side, these findings are in line with evidence from previous studies supporting the associations between PF processes and aspects of daily functioning in GI conditions.”
From Preliminary investigation of the associations between psychological flexibility, symptoms and daily functioning in people with chronic abdominal pain (2021) · cites this paper as [30]
The Introduction links acceptance- and mindfulness-based processes to goal-oriented behaviour despite IBS symptoms, supporting a connection between PF processes and daily functioning. But the Treatment effects section reports improved IBS willingness without significant changes in activity engagement or quality-of-life impact; the paper does not establish the claimed associations between PF processes and functioning. (LLM, conf=0.78)
Experimental — accuracy not yet measuredPrevious studies of ACT for IBS showed significant improvement in acceptance after the treatment, maintained at follow-up.
“Previous studies of ACT for IBS29,30 showed significant improvement in acceptance after the treatment, maintained at follow-up.”
From Preliminary investigation of the associations between psychological flexibility, symptoms and daily functioning in people with chronic abdominal pain (2021) · cites this paper as [30]
The Treatment effects section reports improved IBS acceptance, and Table 2 shows a significant increase in the IBS-AAQ total score at two months. The increase was not significant at the six-month follow-up, so this paper does not support the claim that the improvement was maintained at follow-up. (LLM, conf=0.91)
Experimental — accuracy not yet measured
A 1-day ACT intervention can be useful to increase acceptance of IBS.
“Even so, a 1-day ACT intervention can be useful to increase acceptance of IBS [91,92].”

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.
