Fibromyalgia rapid screening tool: linguistic adaptation of the Russian version
Introduction. The original questionnaire Fibromyalgia Rapid Screening Tool (FiRST) was developed in 2009 and adapted in various countries in various languages. However, there is no adapted Russian-language version of FiRST. Objective. Linguistic adaptation of the Russian-language version of FiRST. Material and methods. Linguistic adaptation of the Russian-language version of FiRST was carried out in five stages: I) direct translation by three translators; II) development of one version of direct translation; III) reverse translation by two native English speakers; IV) development of one reverse version and its discussion by a committee of experts; V) preliminary testing of the Russian version in three groups: 50 patients with fibromyalgia; 30 patients with chronic non - specific back pain; 30 people who do not complain of pain syndrome. Results. A Russian-language version of FiRST has been developed to detect fibromyalgia. The use of the questionnaire in 50 patients with fibromyalgia, 30 patients with chronic nonspecific back pain, 30 people without back and limb pain did not cause comments from either the patients or the doctors who examined the patients. Filling out the Russian-language version of FiRST took no more than 3 minutes. Conclusion. The Russian-language version of FiRST can be used to evaluate its psychometric properties in clinical practice.
