Arabic validation of the Urogenital Distress Inventory and Adapted Incontinence Impact Questionnaires--short forms.
OBJECTIVE
The purpose of this study was to adapt the IIQ-7 to suit the Egyptian culture and then to assess validity and reliability of the adapted and translated IIQ-7 and UDI-6.


METHODS
IIQ-7 was modified to suit Egyptian culture. Linguistic validation of the two questionnaires was done. Initial test-retest reliability and internal consistency of adapted translated questionnaires were done in a pilot study. The final validity, test-retest reliability and internal consistency study included 204 women with urinary incontinence (UI). Participants completed the two questionnaires at enrollment and after 2 weeks. All participants underwent urodynamics. Baseline urodynamic diagnosis was compared with diagnoses made by questionnaires to assess validity.


RESULTS
Test-retest reliability was excellent for both the IIQ-7 and UDI-6. For the UDI-6, the mean difference (SD) between first and second visits was -1.63 (7.0), and the 95% CI for the mean difference was -2.6 and -0.68. The 95% limits of agreement were -15.3 and 12.0. Lin's concordance correlation coefficient (LCCC) (95% CI) for the UDI was 0.89 (0.85 and 0.91). For the IIQ-7, the mean difference (SD) was 0.37 (7.1), and the 95% CI for the mean difference was -0.60 and 1.3. The 95% limits of agreement were -13.5 and 14.2. LCCC (95% CI) for the IIQ was 0.90 (0.87 and 0.92). Internal consistency as assessed using Cronbach's alpha was 0.32 and 0.31 for the UDI-6 and IIQ-7, respectively. Validity assessments indicated that both IIQ and UDI scales can distinguish objective disease states.


CONCLUSIONS
UDI-6 and the modified IIQ-7 are easy to administer, test-retest reliable, and valid questionnaires, with relatively low internal consistency.
