Linguistic validation and cognitive assessment of the French version of the Acute Cystitis Symptom Score questionnaire

International audienceINTRODUCTION: The Acute Cystitis Symptom Score (ACSS) questionnaire first developed in Russian and Uzbek languages and now available in many other languages can be used for clinical diagnostics and patient-reported outcome (PRO) in female patients with acute uncomplicated cystitis (AUC). The aim of the current study was the linguistic validation and cognitive assessment of the French version of the ACSS questionnaire according to internationally accepted guidelines. METHODS: After two forward translations from Russian into the French language and backward translation into Russian and Uzbek, the two original languages, the scientific committee (SC) performed a slightly adapted French version, which finally was cognitively assessed by female subjects with different ages and educational levels and medical professionals, such as nurses, physicians, and pharmacists. RESULTS: All comments of the female subjects and professionals were discussed within the SC and after slight, but necessary adaptations, the SC agreed on the final study version of the French ACSS. CONCLUSION: Now, the linguistically validated and cognitively assessed French version of the ACSS can be used for clinical studies and practice
