Quality of Life in Persons with Irritable Bowel Syndrome (Development and Validation of a New Measure)

Abstract

How irritable bowel syndrome (IBS) and its treatment affect quality of life (QOL) is important. To develop a quality-of-life measure specific to irritable bowel syndrome, items were generated using a conceptual model and qualitative interviews with persons diagnosed using the Rome criteria. Symptom frequency and bothersomeness indices were created. Psychometric evaluation methods involved an initial cross-sectional survey followed by a repeat survey. The resulting 34-item measure demonstrated high internal consistency (Cronbach's alpha = 0.95) and high reproducibility (ICC = 0.86) with average time of seven days (SD = 1). For discriminant validity: number of symptoms (P < 0.05), self-reported severity of symptoms (P < 0.001), and the functional bowel disorder severity index (P < 0.001) significantly predicted IBS-QOL scores. Convergent validity and analyses confirmed predictions that scores are more closely related to psychological well-being (0.45) than to function (0.36). We conclude this measure meets established psychometric criteria for reliability and validity; testing of its responsiveness is warranted.

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.
