Abstract

OBJECTIVES: Psychosocial factors may drive people with irritable bowel syndrome (IBS) to seek health care, but whether psychological factors are causally linked to IBS is controversial. One hypothesis is that IBS is a heterogeneous syndrome comprising two distinct conditions, one psychological and the other biological. However, it is unclear how many people with IBS in the community have little somatization and minimal psychosocial distress. The aim of our study was to estimate the proportion of people with IBS in a representative US community, who have low levels of somatic and psychological symptoms. METHODS: The cohort comprised subjects from three randomly selected population studies from Olmsted County, Minnesota. All of them filled out a validated gastrointestinal (GI) symptom questionnaire, the Symptom Checklist-90-R (SCL-90-R), and the Somatic Symptom Checklist (SSC) comprising 11 somatic complaint items. Logistic regression models were used to evaluate the associations between somatic symptoms/psychosocial factors and IBS, adjusting for age and gender. RESULTS: Of the 501 eligible subjects, 461 (92%) provided complete data (mean age=56 years, 49% female). IBS (Rome II criteria) was associated with both higher SSC and Global Severity Index (GSI of SCL-90-R) scores. Among subjects with high (75th percentile) SSC scores, 43% reported IBS vs. 10% of those with low (<25th percentile) SSC scores. Among those with high (60) GSI scores, 23% reported IBS vs. 6% with low (<40) GSI scores. Specifically, none of the IBS subjects had both low SSC and low GSI scores. CONCLUSIONS: Psychological factors and somatization are strongly associated with IBS in the community. However, IBS may not be related to low psychological distress and/or somatization.

There is little community data on the relationship between IBS and somatization or psychosocial distress.
“In addition, few data regarding the association between IBS and somatization and/or psychosocial distress exist in the community.”
The paper relies on this without support.
The extent of psychological distress among community IBS sufferers is unclear because prior studies have not documented how many are entirely free of psychological comorbidity.
“However, the burden of psychological distress in IBS remains unclear in the community, as studies have failed to document how many IBS sufferers are totally free of psychological comorbidity.”

Percentages, sums and reported differences re-computed from the paper’s own numbers.

Each contradiction between two passages listed here was confirmed by an independent check.

IBS proportion in high SSC group differs across sections
Major
The abstract reports 43% IBS prevalence among subjects with high SSC scores, while the Results section later reports 40% for the same high SSC comparison. These are different values for the same subgroup comparison and are not explained as due to a different denominator or rounding.
IBS proportion in high GSI group differs across sections
Major
The abstract reports 23% IBS among subjects with high GSI scores, while the later Results section reports 33% for the same high-GSI comparison. These values conflict and cannot both describe the same subgroup result.
Female proportion differs between abstract and results
Minor
For the same 461 subjects, the abstract reports 49% female and the Results section reports 48%.
Number of associated somatic complaints changes from seven to eight
Minor
The Predictors of IBS section says seven complaints were associated with IBS, while the Discussion says eight were. The predictors statement also names only three exceptions among 11 complaints, leaving eight rather than seven.

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.

A language model drew the claims from the paper on 2026-09-28, under version 3 of the claim definition (prompt extract-v3).

A second model labelled each claim on 2026-09-28 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).

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.
