Abstract

Background—Life stress contributes to symptom onset and exacerbation in the majority of patients with irritable bowel syndrome (IBS) and functional dyspepsia (FD); research evidence is conflicting, however, as to the strength of these effects. Aims—To test prospectively the relation of chronic life stress threat to subsequent symptom intensity over time. Patients—One hundred and seventeen consecutive outpatients satisfying the modified Rome criteria for IBS (66% with one or more concurrent FD syndromes) participated. Methods—The life stress and symptom intensity measures were determined from interview data collected independently at entry, and at six and 16 months; these measures assessed the potency of chronic life stress threat during the prior six months or more, and the severity and frequency of IBS and FD symptoms during the following two weeks. Results—Chronic life stress threat was a powerful predictor of subsequent symptom intensity, explaining 97% of the variance on this measure over 16 months. No patient exposed to even one chronic highly threatening stressor improved clinically (by 50%) over the 16 months; all patients who improved did so in the absence of such a stressor. Conclusion—The level of chronic life stress threat predicts the clinical outcome in most patients with IBS/FD.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Early life experiences, adult stressors, lack of social support, and other social learning experiences can affect physiological and psychological responses and may precipitate abdominal distress and psychiatric disorders.

    “Early life experiences (e.g., abuse), adult stressors (e.g., divorce or bereavement), lack of social support, and other social learning experiences can affect both an individual’s physiological and psychological responses, and may precipitate abdominal distress, as well as psychiatric disorders (4,7–11).”
  • Increased intestinal permeability is a critical event in the onset of clinical symptoms of GI disorders including IBS and IBD.

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.
