RSI and RFS questionnaires are a basic and common method used for initial diagnosis of laryngopharyngeal reflux (LPR). However, they only measure symptoms which may or may not be concurrent with LPR. The severity of these symptoms is assessed either by the patients themselves (with the use of the Reflux Symptoms Index – RSI) or by the doctor specialising in the field (with the use of the Reflux Finding Score – RFS). Therefore, the findings of the questionnaire may to a large extent depend on the study population – its demographic and cultural characteristics; the extent to which the medical terms used in the questionnaires are understood; and on the linguistic aspects and translation choices. As for the Polish language versions of these questionnaires, there is no reliable analysis of their consistency and if they reach the assumed goal. The studies we have conducted on a group of 84 patients show that we encounter at least one of the above-mentioned problems. Therefore, to make the questionnaires reliable and useful for diagnosis, it is necessary to conduct a formal validation of their translation and to conduct studies on reference groups.
