The Incontinence Outcome Questionnaire: an instrument for assessing patient-reported outcomes after surgery for stress urinary incontinence.
The aim of this study is to develop and psychometrically test a questionnaire (Incontinence Outcome Questionnaire, IOQ) for assessing quality of life (QOL) after surgery for stress urinary incontinence that can be used as a single measurement after the intervention. A total of 171 patients who underwent the tension-free vaginal tape (TVT/TVT-O) operation for stress urinary incontinence completed the King s Health Questionnaire (KHQ), the Short Form-12 (SF-12) and the IOQ. The internal consistency, internal and external validity and responsiveness of the IOQ were tested. The IOQ-QOL subscale showed good internal consistency (Cronbach's alpha=0.83) and significant correlations with the KHQ and the SF-12 scales (r=0.30-0.56). Partial correlations with objective parameters showed a significant relation for the IOQ-QOL subscale with objective continence/incontinence. The results of our study suggest that the IOQ is a valid and reliable instrument for assessing QOL after incontinence surgery and can be used if baseline or pre-operative data are unavailable.
