Evaluation of the German Short-Form Qualiveen Questionnaire

Study Overview
=================
Brief Summary
-----------------
Two questionnaires (Qualiveen full version and Qualiveen short-form (SF)), the project information and the consent form will be sent to individuals who are scheduled for an annual control at the urological out-patient clinic of the Swiss Paraplegic Centre and who fulfill the inclusion criteria. The patients will be asked to complete the two questionnaires and to bring the completed questionnaires and the signed consent form to the annual control at the Swiss Paraplegic Centre. Participants who have consented and completed the two questionnaires will receive the two questionnaires a second time 14 days later. The primary objective of this project is to validate the German version of the SF Qualiveen questionnaire. The secondary objective is to evaluate the measurement properties of the German SF Qualiveen questionnaire in comparison with the full version.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| total score | Total score of the Qualiveen questionnaire is the arithmetic mean of the four sub-scores. The sub-scores are assessed using a five-point Likert scale (minimum score 0, maximum score 4). The total score indicates how much quality of life is affected by bladder problems. The higher the score the more quality of life is affected. | baseline | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| bother with limitations score | Score of the domain bother with limitations of the Qualiveen questionnaire assessed with five-point Likert scale (minimum score 0, maximum score 4).The score indicates how much limitations due to bladder problems bother the affected individual. The higher the score the more the affected individuals are bothered. | baseline | 
| change in bother with limitations score | Score of the domain bother with limitations of the Qualiveen questionnaire assessed with five-point Likert scale (minimum score 0, maximum score 4).The score indicates how much limitations due to bladder problems bother the affected individual. The higher the score the more the affected individuals are bothered | baseline; 14 days | 
| frequency of limitations score | Score of the domain frequency of limitations of the Qualiveen questionnaire assessed with five-point Likert scale (minimum score 0, maximum score 4).The score indicates how often affected individuals experience limitations due to bladder problems. The higher the score the more often the affected individuals experience limitations due to bladder problems. | baseline | 
| change in frequency of limitations score | Score of the domain frequency of limitations of the Qualiveen questionnaire assessed with five-point Likert scale (minimum score 0, maximum score 4).The score indicates how often affected individuals experience limitations due to bladder problems. The higher the score the more often the affected individuals experience limitations due to bladder problems. | baseline; 14 days | 
| fears score | Score of the domain fears of the Qualiveen questionnaire assessed with five-point Likert scale (minimum score 0, maximum score 4).The score indicates how much fear due to bladder problems the affected individuals experience. The higher the score the more fear the affected individuals experience | baseline | 
| change in fears score | Score of the domain fears of the Qualiveen questionnaire assessed with five-point Likert scale (minimum score 0, maximum score 4).The score indicates how much fear due to bladder problems the affected individuals experience. The higher the score the more fear the affected individuals experience | baseline; 14 days | 
| feelings score | Score of the domain feelings of the Qualiveen questionnaire assessed with five-point Likert scale (minimum score 0, maximum score 4).The score indicates how much feelings are affected by bladder problems. The higher the score the more the feelings are affected. | baseline | 
| change in feelings score | Score of the domain feelings of the Qualiveen questionnaire assessed with five-point Likert scale (minimum score 0, maximum score 4).The score indicates how much feelings are affected by bladder problems. The higher the score the more the feelings are affected. | baseline; 14 days |
