Cross-cultural adaptation and validation of the Russian version of the Foot and Ankle Ability Measures (FAAM-Ru); [Кросс-культурная адаптация и валидация русскоязычной версии оценочной системы Foot and Ankle Ability Measures (FAAM-Ru)]

The Foot and Ankle Ability Measure (FAAM) assessment system is used for self-assessment of the function and daily activity of patients with foot or ankle joint diseases. The scale is validated in 13 different languages, but not in Russian, and allows for evaluation in a wide range of diseases. Aim. The aim of the study is a cross-cultural adaptation of the FAAM evaluation system into Russian and a subsequent validation of the Russian-language version of FAAM (FAAM-Ru). Material and methods. The study consists of 2 stages. At the first stage, cross-cultural adaptation was performed based on the recommendations of the International Society for Pharmacoeconomics and Outcomes Research (ISPOR). At the second stage, validation of the scale relative to the EuroQol-5D-3L evaluation system was performed among patients requiring planned surgical treatment of foot or ankle joint diseases. Results. Internal consistency or uniformity of the evaluation scale of the Kronbach alpha coefficient FAAM-Ru ADL: 0.961 (CI 95% 0.927–0.984, p<0.05); FAAM-Ru Sport: 0.956 (CI 95% 0.914–0.982, p<0.05). ICC FAAM ADL Retest reliability: 0.889 (CI 95% 0.844–0.912, p<0.05), FAAM Sport: 0.858 (95% CI 0.821–0.868, p<0.05). Conclusion. The results of the FAAM-Ru ADL and FAAM-Ru Sport studies have high values of uniformity of the evaluation scales by the Cronbach’s alpha coefficient (for ADL: 0.961; Sport: 0.956), which is slightly less in the Sport category than in the original questionnaire (ADL: 0.96; Sport: 0.98). From this it can be concluded that the questions in the questionnaires correspond adequately to each other and there are no significant differences from the original questionnaires. © 2024 Geotar Media Publishing Group.
