Abstract

Objective: To translate and validate an Arabic (Tunisian) version of the Urogenital Distress Inventory short form (UDI-6) and Incontinence Impact Questionnaire short form (IIQ-7), which can be used reliably in daily practice and clinical research for Tunisian and Arabic populations. Patients and methods: This cross-sectional study was conducted from January to June 2018. The UDI-6 assesses the presence of urinary incontinence (UI) and the degree of impairment that it causes, whilst the IIQ-7 evaluates women's life quality with lower urinary tract symptoms. As UI is a relatively common condition in middle-aged and older women these tools are utilised worldwide. The Arabic (Tunisian) translation and cultural adaptation of the UDI-6 and IIQ-7 was achieved via the forward/backward method and comprehension test within a group of 15 patients. Psychometric validation included testing the questionnaire on a group of 35 patients. Intra-rater reliability was evaluated by calculation of the intraclass correlation coefficient (ICC) for each item of the questionnaires. Cronbach's α was used to assess internal consistency. The International Consultation on Incontinence Modular Questionnaire short form (ICIQ-SF), in its Arabic version, was used as the 'gold standard'. Results: For the UDI-6, the ICC was 0.98 demonstrating excellent intra-rater reliability and Cronbach's α was 0.99 (>0.9), confirming an excellent correlation between the different items. Internal consistency (Cronbach's α 0.99) and test-retest reliability of the IIQ-7 (ICC 0.98) were very good. For both questionnaires, the κ values for each item ranged from 0.77 to 0.96. Conclusions: We found that the UDI-6 and IIQ-7 questionnaires were valid tools that can be used reliably in daily practice and clinical research for Tunisian and Arabic women with UI.
