Validation of the Spanish version of the short forms of the Urogenital Distress Inventory (UDI-6) and the Incontinence Impact Questionnaire (IIQ-7) in pregnant women. Gac Sanit [online]. 2011, vol.25, n.5, pp. 379-384. ISSN 0213-9111. http://dx.doi.org/10.1590/S0213-91112011000500007.
Objective: To validate two measurement instruments, the UDI-6 and the IIQ-7, for the study of urinary incontinence and its impact on the quality of life of pregnant women. Methods: We carried out a validation study of a diagnostic tool. A total of 181 pregnant women completed the UDI-6 and IIQ-7 questionnaires. Feasibility, internal consistency, reliability, and construct and criteria validity were analyzed. Results: Self-administration of the short forms of the UDI-6 and IIQ-7 questionnaires took less than 5minutes and the maximum rate of no answer per item was 3.3%. Cronbach's alpha was 0.667 for the UDI-6 and was 0.910 for the IIQ-7. The reliability of the UDI-6 in the diagnosis of urinary incontinence showed Kappa statistic values of between 0.856 and 0.966, and the intra-class correlation coefficients of the UDI-6 and IIQ-7 were 0.902 and 0.954, respectively. Average values of the UDI-6 and IIQ-7 were higher in women with mixed incontinence, were lower in women with stress incontinence and increased with daily losses (p<0.01). The correlation between the UDI-6 and the International Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF) (CCI=0.497; 95% CI: 0.326-0.625) and between the IIQ-7 and ICIQ-SF (CCI=0.472; 95% CI: 0.268-0.619) was moderate. The sensitivity and specificity of the UDI-6 for the diagnosis of urinary incontinence was 98.9% and 86.5%, respectively. Conclusions: The Spanish versions of the IIQ-7 and UDI-6 are feasible, reliable, consistent and valid in the measurement of symptoms and quality of life in pregnant Spanish women with urinary incontinence.
