·AIM:To revise visual function index scale(VF-14)and evaluate the reliability and validity of the Chinese revision,in order to provide the basis to explore the internal appropriate visual function evaluation tools.METHODS:Ophthalmologists and age-related cataract patients were studied,data were collected for the formation of revision;age-related cataract patients were selected as research subjects,the general situation and scale data were collected.The reliability and validity of the scale were analyzed using t’test and correlation analysis.RESULTS:VF-14 scale Chinese revision reliability:(1)test-retest reliability:the ICC range value of scale items and total score was 0.814-0.976;(2)internal consistency:scale Cronbach’α coefficient was 0.916;(3)interrater reliability:the ICC range values of scale items and total score was between 0.854 and 0.996;(4)split-half reliability:the split-half reliability coefficient of scale was 0.817.Validity of the Chinese revised VF-14 scale:scale items included all aspects of visual function measurement;correlation coefficient was 0.67 and 0.46 respectively using preoperative and postoperative visual function and quality of life scale scores and the VF-14 scores of the Chinese revision to take correlation analysis.The value of t’test of 50 patients with preoperative and postoperative VF-14 scores for the Chinese revision was 17.18,P<0.05.Using the patient subjective improvement of visual function and changes with the scale scores to do correlation analysis showed that the correlation coefficients of the scale was between 0.35 and 0.62.CONCLUSION:The Chinese revision scale of visual function index(VF-14)has good reliability and validity.
