Abstract:
Objective:To compare the application effect among Western Ontario and McMaster University Osteoarthritis Index (WOMAC) scale, Medical Outcomes Study 36-item Short Form (SF-36) scale and "Assessment for Therapeutic Efficacy on Kashin-Beck Disease" (WS/T 79-2011) standard in the evaluation of therapeutic effect of patients with Kashin-Beck disease, which could provide basis for the treatment evaluation of patients with Kashin-Beck disease.Methods:A total of 213 patients with Kashin-Beck disease in Gansu Province were investigated. WOMAC scale, SF-36 scale and standard of WS/T 79-2011 were used to analyze the quality of life of patients before and after treatment. The reliability, construct validity, content validity, discriminant validity of WOMAC and SF-36 scales were compared. Correlation between WOMAC, SF-36 scales and standard of WS/T 79-2011 were evaluated.Results:Both WOMAC and SF-36 scales had good construct validity and content validity (construct validity showed WOMAC and SF-36 scales contained 1 and 2 common factors, respectively; content validity showed WOMAC and SF-36 scales contained 3 and 8 common factors, respectively). The reliability and discriminant validity of WOMAC scale were better than those of SF-36 seale (reliability showed WOMAC reliability coefficient ≥0.934, the reliability coefficient of SF-36 scale was ranged from 0.386 to 0.999. Discriminant validity showed there were differences in 3 dimensions of the WOMAC scale before and after treatment, while there were differences in 6 out of 8 dimensions of the SF-36 scale). The correlation coefficients between WOMAC scale and standard of WS/T 79-2011 ranged from 0.175 to 0.437, the correlation coefficients between SF-36 scale and standard of WS/T 79-2011 ranged from - 0.434 to - 0.099 ( P < 0.05). Conclusion:The reliability, discriminant validity and correlation with the standard of WS/T 79-2011 of WOMAC scale are better than those of SF-36 scale in efficacy evaluation of patients with Kashin-Beck disease.
