Validation of the Wexner scale in a Hebrew-speaking population

Introduction: The Cleveland Clinic Incontinence Score, known as the Wexner Score (WS), is a simple, disease-specific questionnaire for anal incontinence (AI) assessment. We aimed to translate and validate a Hebrew version of the WS. Methods: Between November 2018 and December 2019, the WS was back translated and reviewed by a multidisciplinary pelvic floor team. The questionnaire was filled out by patients visiting the urogynecology and surgical pelvic floor clinics. Two weeks after completion, the patients were contacted using telephone surveys to assess the test-retest reliability examination. Construct validity was assessed by comparing the WS to the Colorectal-Anal Distress Inventory 8 (CRADI-8), a part of the validated Hebrew version of the Pelvic Floor Distress Inventory questionnaire (PFDI-20). Results: Overall, 91 female patients completed the WS questionnaire. Eighty-five percent (n = 78) responded to the re-test WS questionnaire. A high intraclass coefficient of 0.87 was found in the WS total score, with a range from 0.82 to 0.86 for its subscales. A significant positive relationship between the Hebrew versions of the WS and CRADI-8 scores was established (r = 0.66, p < 0.0001). Conclusion: A new, Hebrew-translated version of the WS is a reliable and valid instrument for assessing AI.
