Validation of the Swedish version of the incontinence impact questionnaire and the urogenital distress inventory.
Objective. To validate the Swedish versions of the Incontinence Impact Questionnaire (IIQ-7) and Urogenital Distress Inventory (UDI-6). Design and setting. Prospective study, university hospital. Population and method. We analyzed reliability, validity, and responsiveness in a clinical sample of 96 women with urinary incontinence. Main outcome measures. Construct and criterion validity, reliability via test-retest and internal consistency. Responsiveness via calculation of effect size. Result. Test-retest reliability ranged from moderate to almost perfect. Cronbach's alpha was 0.39 (UDI-6) and 0.83 (IIQ-7). Effect size calculation of change after treatment demonstrated good responsiveness. The effect size at six months was moderate in the Stress Urinary Incontinence group and small in the Urge Urinary Incontinence + Mixed Urinary Incontinence group. There was a moderate to strong correlation between UDI-6 and IIQ-7 and treatment satisfaction at six, 12, and 24 months for both groups. Conclusion. The UDI-6 scale did not produce the same solid result in the psychometric analysis as the IIQ-7 scale, but these newly translated Swedish forms of UDI-6 and IIQ-7 show good responsiveness and are easy to administer and to fill out.
