Frequency and severity of the symptoms of irritable bowel syndrome across the anxiety disorders and depression
Abstract
High rates of irritable bowel syndrome (IBS) symptoms have been reported in individuals diagnosed with anxiety and depressive disorders. However, most studies have investigated these relations in a single disorder, rather than a heterogeneous group of patients, thereby not allowing for comparisons across anxiety disorders and depression, or for considering the effects of comorbidity. Thus, the present study investigated the symptoms of IBS in a diverse group of patients (N=357) by administering questionnaires and a diagnostic interview. A high frequency of IBS symptoms was found in patients with panic disorder, generalized anxiety disorder, and major depressive disorder. However, the frequency of IBS symptoms in patients with social anxiety disorder, specific phobia, and obsessive-compulsive disorder was comparable to rates found in community samples. In addition, anxiety sensitivity and illness attitudes and intrusiveness were predictive of elevated IBS symptomatology. Together, these findings emphasize the role physiological symptoms of anxiety and worry in the co-occurrence of the anxiety disorders and IBS.

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.
