Abstract

Aims: To compare the International Consultation on Incontinence Questionnaire‐Urinary Incontinence Short Form (ICIQ‐UI SF) with the Incontinence Severity Index (ISI), and to propose intervals for four severity levels of ICIQ‐UI SF. Methods: Cross‐sectional, Internet‐based study of 1,812 women responding to a general health questionnaire. Four severity levels for the ICIQ‐UI SF scores were constructed by iteratively adjusting the ranges for these levels until maximum Kappa scores were obtained when cross‐tabulated with the ISI in a random sample of half of the women with urinary incontinence. Using these intervals, weighted Kappa was calculated for the remaining women as a validation process. Results: Three hundred forty‐three women had urinary incontinence, and completed the ISI and the ICIQ‐UI SF. A high correlation between the ISI and ICIQ‐UI SF scores with versus without the QoL item was found (Spearman's rho = 0.62, P < 0.01 vs. rho = 0.71, P < 0.01, respectively). Maximum Kappa with quadratic weighting was obtained for the following scale for the ICIQ‐UI SF: slight (1–5), moderate (6–12), severe (13–18) and very severe (19–21) (Kappa = 0.61), and without the QoL item: slight (1–3), moderate (4–5), severe (6–9) and very severe (10–11) (Kappa = 0.71) in the development sample. Correspondingly, for the validating sample, maximum Kappa with quadratic weighting was 0.61 and 0.74. Conclusions: A high correlation between the ICIQ‐UI SF and the ISI was found. The ICIQ‐UI SF may be divided into the following four severity categories: slight (1–5), moderate (6–12), severe (13–18) and very severe (19–21). Neurourol.

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.
