Validation of the Spanish version of the Urogenital Distress Inventory short form and Incontinence Impact Questionnaire short form for women between the ages of 18 and 65

To analyze the reliability of the Spanish version of the Urogenital Distress Inventory short form (UDI-6) and Incontinence Impact Questionnaire short form (IIQ-7) questionnaires for assessing the presence of urinary incontinence, the degree of impairment and the impact on quality of life for Spanish women between the ages of 18 and 65. A total of 150 women were enrolled throughout Spain and were administered the UDI-6 and IIQ-7 questionnaires in 2 registries performed with a 15-day interval. The ICIQ-short form, in its Spanish version, was used as the gold standard. In the reliability analysis of the UDI-6, an internal consistency of 0.973 and an intraclass correlation of 0.974 were achieved, with a 95% CI between 0.964 and 0.981. For the IIQ-7, the internal consistency was 0.984 and the intraclass correlation was 0.985, with a 95% CI between 0.985 and 0.977. For both questionnaires, the kappa values for each item ranged from 0.717 to 0.876. The Spanish version of the UDI-6 and IIQ-7 questionnaires reliably and consistently assess the urogenital symptoms and their impact on the quality of life of Spanish women between 18 and 65 years of age.
