SummaryObjectiveTo develop a French version of the Reflux Symptom Index (Fr-RSI) and to assess its internal consistency, reliability, and clinical validity.Study DesignControlled, prospective trial.Materials and MethodsForty-four patients with a reflux finding score >â7 and an Fr-RSIâ>â13 were enrolled and treated with 20âmg of pantoprazole twice daily and diet changes for 3 months. Ninety asymptomatic subjects were also included in the study. To assess reliability, Fr-RSI was completed twice within a 7-day period. Validity was assessed by comparing Fr-RSI scores with scores from the Voice Handicap Index (VHI) in 24 of 44 patients, at baseline and at 3 months posttherapy.ResultsThe mean values of Fr-RSI at baseline and after 7 days were 20.17â±â5.76 and 19.75â±â7.08, respectively, for patients with laryngopharyngeal reflux (LPR) and 4.02â±â3.49 and 3.71â±â3.82, respectively, for controls. The test-retest reliability was high in patients with LPR (rBPâ=â0.78) and in healthy subjects (rBPâ=â0.80). Cronbach's alpha was 0.85, indicating high internal consistency. The mean Fr-RSI score significantly improved from a baseline of 20.17â±â5.76 to 5.58â±â3.65 after 3 months of treatment (Pâ=â0.001), and the initial mean VHI total score significantly improved from 20.29â±â19.62 to 12.87â±â12.04 after treatment (Pâ=â0.029), indicating validity of the results. However, of the subcategories of the VHI, only the mean physical score improved from a baseline of 11.19â±â9.22 to 7.35â±â5.96 after treatment (Pâ=â0.016).ConclusionThe Fr-RSI developed in this study demonstrated both reliability and validity. It can be easily administered to assist in diagnosing and monitoring of LPR in French-speaking patients.
