Validation of the modified Rankin Scale in Russia

Objective: to develop a Russian version of the modified Rankin Scale (mRS) and to assess its psychometric properties.

Patients and methods. The investigation involved 50 patients (25 women, 25 men) over 18 years of age (mean age, 56 years) with an acute cerebrovascular accident diagnosis. During the validation procedure, the authors carried out the linguocultural ratification of mRS, prepared its Russian-language version, and then assessed its psychometric properties (reliability, sensitivity, validity).

Results and discussion. Translation and linguistic adaptation of mRS was successfully completed. The results obtained in assessing the psychometric properties of the developed Russian version of the scale reflect its high reliability and the valid and reliable indicators of its sensitivity. A statistical study of constructive and content validity also determined the high significance of differences.

Conclusion. The investigation has resulted in the official Russian version of mRS, which is recommended for use by neurologists and rehabilitation specialists in both daily clinical practice and in clinical trials.
