Validation of pelvic floor related symptom and Quality of Life questionnaires in Dutch patients.

The objective of this study is to validate the Dutch versions of Pelvic Floor Related Questionnaires (Urogenital Distress Inventory Short Form: UDI-6; Incontinence Impact Questionnaire Short Form: IIQ-7, International Index of Erectile Function short form: IIEF-5, Pelvic Floor Distress Inventory Short Form: PFDI-20, Pelvic Floor Impact Questionnaire Short Form: PFIQ-7, Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire Short Form: PISQ-12, Fecal Incontinence Quality of Life Scale: FIQL, Fecal Incontinence Severity Index: FISI).



The linguistic validation of the questionnaires will be performed through a multistep process: backward and forward translations coordinated by clinical investigators, followed by a pretest. The final versions will be administered to a larger sample of patients, aged 18 years or older, with complaints for at least 3 months. To evaluate test-retest relaibility, patients will be re-rated after 1 week. To test the questionnaires' capacity to discriminated patients with or without symptoms (cases and controls, respectively) a sample of 50 healthy patients will be enrolled.

To test for convergent validity, a voiding diary, defecation diary, SF-12 and EuroQol-5 will be used.

To measure the sensitivity of change; questionnaires will be filled out 3 months post therapy.



Hypothesis: Pelvic floor related symptom and Quality of Life questionnaires (IIQ-7, UDI-6, IIEF-5, PISQ-12, PFIQ-7, PFDI-20, FISI, FIQL) in Dutch are valid instruments, which can be used reliably in daily practice and clinical research.
