OBJECTIVE: To assess the measurement properties of the International Consultation on Incontinence-Perinatal Pelvic Health Self-Assessment Questionnaire (ICIQ-PPHSAQ) and to identify symptom subscales for scoring.
DESIGN, SETTING AND POPULATION: Two cohorts of perinatal women (antenatal and postnatal) at nine NHS trusts in England completed ICIQ-PPHSAQ at baseline (16-19 weeks' gestation for the antenatal cohort and 6-9 weeks postnatal for the postnatal cohort) and at up to three further timepoints, with follow-up extending to 9 months postnatal.
METHODS: Descriptive analyses and exploratory factor analyses (EFAs) identified symptom subscales from which subscale scores were calculated. Internal consistency was evaluated using Cronbach's alpha (α). Test-retest reliability was assessed using an interval of 1 week after baseline, using weighted Kappa (κ) for individual ordinal items and the intraclass correlation coefficient (ICC) for subscale scores. Construct validity and known-groups validity were assessed by comparison with the Patient Global Impression of Severity (PGI-S). Responsiveness was assessed by examining the mean differences between baseline and each timepoint.
RESULTS: A total of 162 antenatal women who were 16-19 weeks gestation, and 173 women 6-9 weeks postnatal were recruited. Almost all the items performed acceptably in the test-retest analyses and completion rates were high in all the scored items (< 5% missing data). EFAs derived nine symptom subscales; seven of which had acceptable overall reliability indicators, except the vaginal symptom and vaginal changes subscales. Known-groups validity was demonstrated for all nine subscales, and six out of nine showed responsiveness to change (p < 0.05) over the study time-period.
CONCLUSION: The study provides evidence supporting the validity and reliability of ICIQ-PPHSAQ, with responsiveness demonstrated across several domains. The instrument can be used to assess perinatal pelvic floor dysfunction risk factors and symptoms in English perinatal pelvic health services.
