Material and Methods: A total of 145 patients treated for stress incontinence completed the Germanl anguage King’sHealth Questionnaire and the SF-36 before and after treatment. A psychometric analysis of the instrument was performed, determining reliability, validity and responsiveness of the King’s Health questionnaire. Results: The subscales of the King’s Health Questionnaire showed a good internal consistency with Cronbach’s alpha coefficients between 0.76 and 0.86. For the German version we defined a new subscale for overactive bladder. This subscale also showed a good internal consistency. The criterion validity measured on clinical parameters showed statistically significant correlations between severity of incontinence and several King’s subscales: Incontinence Impact (r = 0.22, p = 0.013), Personal Relationships(r = 0.24, p = 0.006) and Physical Limitations (r = 0.22, p = 0.010). Regarding responsiveness statistically significant changes before and after therapy were found in the subscales: Incontinence Impact, Physical Limitations, Social Limitations, Personal Relationships, Emotional Problems, and Sleep and Energy Disturbances. Conclusion: The German version of the King’s Health Questionnaire showed good psychometric properties and can be used in clinical trials and in clinical practice for the evaluation of treatments and their impact on urinary incontinence.展开更多
