Russian localization and validation of the BRACE QUESTIONNAIRE

BACKGROUND:According to the literature, the Greek questionnaire on the study of the quality of life of children and adolescents undergoing brace treatment (BRACE questionnaire, abbreviated as BrQ) is informative and reliable, which is confirmed by its validation in different countries. This necessitates the creation ofanadopted Russian version and its validation. AIM:To perform Russian localization and validation of the Greek questionnaire on the study of the quality of life of children and adolescents undergoing brace treatment. MATERIALS AND METHODS:Russian localization and validation of the Russian version of the questionnaire on braces (Ru-BrQ) was carried out in several stages: direct and reverse translations, examination of the questionnaire, formation ofapreliminary version, pilot testing of 104 patients with idiopathic scoliosis on brace treatment, development of the final version, reliability study using the evaluation of Cronbachs alpha criterion and intraclass correlation coefficient (ICC), and provision of the final version. RESULTS:According to the indicators of the overall Ru-BrQ score, 0% of patients scored at the floor and ceiling levels. The average quality of life scores according to Ru-BrQ and in the retest were 72 9.2 and 72.4 9.0 points, respectively. According to the ICC indicator, domains such as general health, self-esteem and aesthetics, vitality, and social functioning showed excellent reliability (0.9). Physical functioning and school activity demonstrated good reliability(0.750.9).Emotional functioning and body pain demonstrated moderate reliability (0.50.75). The Cronbachs alpha coefficient showed that except for the domains emotional functioning and body pain, where good internal consistency was determined (0.8), all other domains confirmed excellent internal consistency (0.9). The Pearson correlation coefficient (index 0.67) revealedanoticeable correlation between Ru-BrQ and the Russian version of SRS-22. CONCLUSIONS:The Russian version isareliable questionnaire for the study of the quality of life of children and adolescents undergoing brace treatment, comparable with the original Greek version of BrQ, and can be recommended for use in practical and scientific activities to assess the effect ofatorso brace on the quality of life in children and adolescents.
