Abstract:
Objective:This study aimed to develop a Chinese version of Quality of life in Epilepsy Inventory(QOLIE-89) and to confirm its psychometric properties.Methods:The original English version QOLIE-89 was adapted to Chinese language through a translation back-translation procedure. The assessment included 204 patients with epilepsy .The test-retest and internal consistency reliabilities, criterion validity and discriminative validity were assessed.Results:The test-retest reliability (Pearson's correlation coefficient) for Chinese version QOLIE-89 was 0.63-0.95 and internal consistency reliability (Cronbach's alpha) was 0.76-0.92. The confirmatory factor analysis indicated that the Chinese version of QOLIE-89 was composed of three dimensions(CMIN/DF=2.17,GFI=0.98, AGFI=0.90, CFI=0.98,RMSEA=0.061), which were physiology, psychology and social function that including 17 factors obtained by exploration analysis ,which can explained 71.91% of total variance. Spearman's rank correlations between Chinese version QOLIE-89 total score and QOLIE-31 total score was 0.96 and domain scores were from 0.86-1.00.QOLIE-89 items could be discriminated well between patients according to epileptic seizures severity and antiepileptic drug side effects.Conclusion:The psychometric properties of the Chinese version QOLIE-89 inventory are fairly good and similar to the American version and can be applied to assess quality of life for adult patients with epilepsy in China.
