Abstract

Introduction and hypothesisThe objective of the present study was to adapt the CONTILIFE, a quality-of-life questionnaire, into Turkish and to reveal its psychometric properties in women suffering from stress urinary incontinence (SUI).MethodsNinety-eight patients with a symptom of SUI participated in the study and filled out the Turkish CONTILIFE. Cronbach's alpha () and intraclass correlation coefficients (ICCs) were evaluated for the internal consistency and test-retest reliability, respectively. Exploratory factor analysis was performed to determine the underlying structure. Criterion validity was analyzed using the correlation coefficients between the total and subscale scores of the CONTILIFE and King's Health Questionnaire (KHQ), the Incontinence Impact Questionnaire-7 (IIQ-7), and the Urinary Distress Inventory-6 (UDI-6).ResultsInternal consistency was found to be strong to very strong (Cronbach's : 0.90-0.96). Test-retest reliability was very strong (ICCs=0.91-0.98, p<0.001). Exploratory factor analysis revealed five significant factors, explained by 74% of the total variance. Total scores on the CONTILIFE were significantly correlated with the KHQ subscales (r=-0.43 - -0.81), IIQ-7 (r=-0.89), UDI-6 (r=-0.66), and ISI (r=-0.66); (p<0.01).ConclusionThe Turkish CONTILIFE is a valid and reliable tool to determine the influence of SUI on health-related quality of life in Turkish women.
