The development of the irritable bowel syndrome-behavioral responses questionnaire
Abstract
Objective Unhelpful behavior related to irritable bowel syndrome (IBS) is often targeted and expected to change in treatments such as cognitive behavioral therapies. However, no scale has previously been produced to assess these dimensions. The aim of this study was to develop and validate an IBS-specific behavioral responses questionnaire.Methods A total of 153 patients with IBS as diagnosed by a general practitioner completed the 28-item Irritable Bowel Syndrome-Behavioral Responses Questionnaire (IBS-BRQ). A total of 117 persons without IBS also completed the IBS-BRQ and were used as a control group. Tests of internal consistency and principal components analyses (PCAs) were performed on both sets of data.Results The scale was found to be both reliable and valid with a high degree of internal consistency for both IBS patients (Cronbach's alpha=.86) and controls (Cronbach's alpha=.89). The scale differentiated significantly between IBS patients and controls (F=221, P<.01). The PCA supported a two-factor solution in both sets of data. Two items were removed from the scale due to low discriminative ability. The criterion validity was high as evidenced by a strong correlation with the Cognitive Scale for Functional Bowel Disorders (CS-FBD) (r =.67, P<.001).Conclusion The IBS-BRQ is a valid and reliable scale that can be used for clinical as well as empirical purposes.

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.
