Abstract

Abstract Purpose The aim of this study was to evaluate the reliability of the Chinese translation version of OSDI-6 questionnaire for dry eye. Methods A total of 270 participants (136 males, 50.4% and 134 females, 49.6%) with a mean age of 28.22 ± 9.01 years were assessed, diagnosed under the criteria put forth by Dry eye workshop (DEWS) completed the Chinese translated version of the OSDI-12 questionnaire (C-OSDI-12). Validity and psychometric properties were analyzed using the study data on the selected items (a new approach called virtual validation). For implementation in the new, shorter C-OSDI-6 questionnaire, 6 items were extracted from the C-OSDI-12 as suggested by the authors of OSDI-6 and compared. Demographic characteristics, validity of total score were evaluated with Spearman rank correlation and Rasch analysis. Results The total scores of C-OSDI-12 and C-OSDI-6 were 30.27 ± 13.19 and 6.95 ± 3.53 respectively. Significant reliability was found between total C-OSDI-6 score and total C-OSDI-12 score (r = 0.865, p < 0.001). Infits and outfits of the C-OSDI-6 were between 1.26 and 0.78. Conclusion The C-OSDI-6 proved to be valid, and psychometrically responsive in Chinese adult dry eye participants. The findings of this virtual validation study need to be confirmed in a longitudinal validation study on the real-world use.
