Validation of the Turkish version of the ICIQ-FLUTS, ICIQ-FLUTS long-form, ICIQ-LUTS quality-of-life, and ICIQ-FLUTS sexual functions.

ABSTRACT

AIMS: To enable the use of ICIQ-FLUTS, ICIQ-FLUTS-long-form (ICIQ-FLUTS-LF), ICIQ-LUTS-quality-of-life (ICIQ-LUTSqol), and ICIQ-FLUTS sexual functions (ICIQ-FLUTSsex) in Turkish speaking women, questionnaires were translated into Turkish and validity, reliability, and sensitivity to change were evaluated in women suffering from urinary incontinence (UI). MATERIALS AND METHODS: Permissions were obtained from ICIQ Advisory Board, English versions of the questionnaires were initially translated into Turkish, then back-translated into English and translations were modified according to recommendations of ICIQ Advisory Board. Pilot testing was performed in 10 women. Validity (content/face validity and discriminant validity), reliability (test-retest reliability and internal consistency), and sensitivity to change were evaluated. RESULTS: A total of 58 women with UI completed ICIQ-FLUTS, ICIQ-LUTSqol, and the ICIQ-FLUTS-LF, and 37 who were sexually active completed ICIQ-FLUTSsex. All women completed same questionnaires 15 days later. More than 90% of women thought that the questions were clear, unequivocal, and comprehensive. Missing data were less than 1% indicating adequate content/face validity. Cronbach's α coefficients were .933 (ICIQ-FLUTS), .979 (ICIQ-LUTSqol), .865 (ICIQ-FLUTS-LF), and .863 (ICIQ-FLUTSsex), representing adequate internal consistency. Kappa values and intraclass correlation coefficient for individual items were over 0.70, indicating adequate test-retest reliability. A total of 52 healthy volunteers completed ICIQ-FLUTS and ICIQ-FLUTS-LF, 30 completed ICIQ-LUTSqol, and 30 sexually active healthy volunteers completed ICIQ-FLUTSsex. All four questionnaires had good discriminant validity. Twenty-eight women with UI were analyzed 3 months after treatment. There was significant improvement in four questionnaires in correlation with pre- and posttreatment bladder diary results showing good sensitivity to change. CONCLUSION: Turkish versions of four ICIQ modules were shown valid and reliable and can be used in Turkish speaking women in the evaluation of UI.
