Journal Title: Journal of Clinical and Diagnostic Research - Year 2018, Vol 12, Issue 5
Abstract
ABSTRACT Introduction: Urinary incontinence is a common health, physical, and social problem in the world. There is an urgent need of effective questionnaires for its evaluation in Iranian women. Aim: The present study aimed to assess validity and reliability of the adapted and translated version of the Incontinence Impact Questionnaire (IIQ-7) and the Urogenital Distress Inventory (UDI-6) in the Persian language. Materials and Methods: This cross-sectional study was conducted from April to October 2015. A sample of 200 consecutive women who participated in this study filled the final version of the questionnaires. Eligible samples were divided into two groups (with and without UI). Standard forward-backward procedure was applied for translating the questionnaires into Persian. Reliability was assessed using test/retest reliability and internal consistency. In addition, validity was evaluated using face and content validity, comparison with known groups, and convergent validity. Results: Two hundred women participated in this study and filled both the questionnaires. Both the normal and incontinent groups had 100 subjects. Mean age of the respondents was 47.52±9.84 years. The content validity analysis produced favourable results. IIQ and UDI successfully discriminated the two groups. There was a significant negative correlation between the two questionnaires and all subscales of the Short Form Health Survey (SF-36). The Cronbach’s alpha coefficient for UDI-6 and IIQ-7 was 0.88 and 0.95, respectively. The Intraclass Correlations (ICC) scores for the Persian language versions were 0.96 for UDI-6 and 0.97 for IIQ-7. Conclusion: This study demonstrated that the newly developed Persian language version of IIQ-7 and UDI-6 are short, valid, and reliable methods for assessing the quality of life of women with UI.
