Abstract
Life quality assessment is one of the most popular and relevant field in modern medicine. Hearing loss due to otosclerosis may significantly affect different areas of the patient’s life, thereby changing the level of quality of life. At the same time, there is a certain subjectivity in the assessment of the patient’s own condition and the expert opinion of the doctor, including due to the discrepancy between the concept of a satisfactory level of quality of life. One of the problems of life quality assessment of patients with otosclerosis among Russian-speaking population is the lack of validated nosologically specific questionnaires. The aim of our study was to assess the quality of life of patients with otosclerosis by means of cross-cultural adaptation and validation of the Russified version of the SPOT-25 questionnaire (Stapesplasty Outcome Test 25) to assess the quality of life of patients with otosclerosis. During the study, the SPOT-25 questionnaire was translated using a double reverse independent translation, agreed and formed into a single version for further validation work. As part of the study, various observation groups were formed, which included patients suffering from otosclerosis and healthy volunteers. The main internal characteristics of the questionnaire were determined, such as validity, reliability, and sensitivity. The results obtained demonstrated sufficient reliability and sensitivity as well as clinical validity of the new condition assessment tool. Thus, the Russified version of the SPOT-25 questionnaire can be used both in further scientific research and in the daily practice of an otorhinolaryngologist.
