Clinical Testing of the Russian Version of the SRS-22 Questionnaire for Adult Scoliosis Patients

Abstract

Objective. To analyze the clinical approbation of the Russian-language version of the SRS-22 questionnaire for adult patients with scoliosis, to assess its reliability using Cronbach's alpha criterion for internal consistency, and to determine its efficacy and specificity by correlation matching with the ODI results and numerical pain scale's scores. Material and Methods. A survey of 196 patients aged over 18 years with spinal pathology was carried out using the SRS-22 questionnaire. The questionnaire results were compared with the Oswestry Disability Index and numerical pain scale. Cronbach's alpha reliability index was used to measure internal consistency of the questionnaire. Variation statistics method was used: calculation of the arithmetic mean and the mean deviation, Pearson correlation coefficient with evaluation according to the Chaddock scale. To evaluate consistency of mean differences, the Student t-test with determination of statistical consistency index was used. Results. The Cronbach's alpha reliability index within domains in adult scoliosis patients was more than 0.7 and demonstrated satisfactory internal consistency of the questionnaire. Comparative analysis of SRS-22 scores revealed that scores of deformity-specific domains (Function, Self-image, Mental health, Satisfaction with management) were higher in patients with scoliosis. High correlation between the SRS-22 Function domain and the ODI was detected. Correlation between the SRS-22 Pain domain and numerical pain scale was moderate. Conclusion. The proposed Russian version of the SRS-22 questionnaire is reliable, specific and effective tool for self-assessment of health status in adult scoliosis patients and can be further used to evaluate the results of surgical treatment.
