Abstract
Aim: The International Consultation on Incontinence Questionnaire—Urinary Incontinence Short Form (ICIQ-UI SF) and the Wexner Scale have been included in the International Consortium for Health Outcomes Measurement core outcome set during pregnancy and childbirth, to measure urinary and anal incontinence. The reliability and validity of these instruments have not been fully evaluated in maternity populations. The aim of this study was to conduct a psychometric evaluation of the ICIQ-UI SF and Wexner Scale. Methods: Consecutive pregnant women (n = 309) who booked for care at one Australian birth facility between August 2017 and April 2018 completed the online surveys. Women who screened positive for urinary and/or anal incontinence were administered the ICIQ-UI SF and/or Wexner Scale during pregnancy (<27 and 36-weeks) and postpartum (6 and 26-weeks). Scale internal consistency, construct validity, and responsiveness were evaluated. Findings: In women with urinary incontinence, the ICIQ-UI SF demonstrated good internal consistency during pregnancy (baseline and 36 weeks) and 6-weeks postpartum (mean inter-item correlation: 0.47, 0.39, and 0.46, respectively), recorded significant change across three time-points, and was sensitive to group differences in age and obesity during pregnancy. Wexner Scale was unsuitable for psychometric analysis due to insufficient numbers of women with anal incontinence. Conclusion: The ICIQ-UI SF is a valid and reliable instrument to measure urinary incontinence during pregnancy and postpartum. The findings support the inclusion of the ICIQ-UI SF in the International Consortium for Health Outcomes Measurement core outcome set for use during the perinatal period. Psychometric analysis of the Wexner Scale in larger maternity populations is recommended.
