Abstract:
Objective:To translate the Glaucoma Symptom Scale (GSS) into Chinese, and to test its reliability and validity.Methods:Following the Brislin questionnaire translation principles, GSS was translated, back-translated and culturally adapted, and the Chinese version of GSS was formed. From January 2021 to June 2022, a total of 210 glaucoma patients in Ophthalmology Outpatient and Inpatient Department of Class Ⅲ Grade A hospitals in Hefei were enrolled as the research objects by the convenience sampling method. The items of the Chinese version of GSS were screened by correlation coefficient method, critical ratio method and Cronbach's α coefficient. The reliability of the Chinese version of GSS was tested using Cronbach's α coefficient, split-half reliability and test-retest reliability. The validity of the GSS was evaluated by content validity and construct validity. Receiver operating characteristic (ROC) curve was drawn to evaluate the predictive ability of the Chinese version of GSS, and to determine the sensitivity, specificity and the most appropriate critical value of GSS. Pearson correlation analysis was used to explore the correlation between the total score of GSS and the score of each item. A total of 210 questionnaires were distributed in this study, and 205 were effectively received, with an effective recovery rate of of 97.62% (205/210) .Results:A total of 2 common factors were extracted by exploratory factor analysis, and the cumulative variance contribution rate was 50.64%. With clinician's diagnosis as the gold standard, the area under the curve of the Chinese version of GSS was 0.916 (95% CI: 0.886-0.947, P<0.01). The optimal critical score of the scale was 73, and the sensitivity and specificity were 85.2% and 87.3%. The concordant Kappa value of the two diagnostic results was 0.749 ( P<0.01). The Cronbach's α coefficient, split-half reliability and test-retest reliability of the Chinese version of GSS were 0.812, 0.781 and 0.912, respectively. Conclusions:The Chinese version of the GSS has good reliability and validity, and is suitable for the screening of glaucoma patients in China.
