Cross-Cultural Validation and Adaptation of the Moroccan Version of the Urinary Incontinence Quality of Life Scale: CONTILIFE

Abstract

Objectives:The objective of this study is to adapt and validate, the CONTILIFE, a quality of life questionnaire, in Moroccan dialect, and to assess its psychometric properties in women suffering from urinary incontinence. Materials and Methods: A total of 104 women were enrolled in the study. The reliability, construct validity, and clinical validity were assessed using the standardized procedures. Results: The results showed that the Moroccan version of the CONTILIFE has very good psychometric properties. Internal consistency was found to be strong (Cronbach's α: 0.87 to 0.96). The inter-rater reliability, and the test-retest for the global score and de six subscale's scores were too well. Results for multitrait scaling analysis showed that all items exceeded the 0.4 criterion for convergent validity in all scales. Item-discriminant validity was 100% successful for all items. Conclusion: The Moroccan version of the CONTILIFE is a valid and reliable tool to assess the impact of urinary incontinence on health-related quality of life in Moroccan women.
