Abstract Objective: To make item analysis on Liver Disease Quality of Life Questionnaire (LDQOL) and to develop a short version questionnaire. Methods: LDQOL were administered to 256 chronic liver disease patients, item analysis of LDLQOL was made and short version of LDQOL was developed based on the results of item analysis. Cronbach’s α coefficient of both the original one and the short version one was calculated. Results: The original questionnaire ceiling effect was from 0-39.6%; flooring effect 0 from 0-34.1%; Cronbach’s coefficient from 0.27 to 0.97. The short version scale questionnaire was made up of the 30 items with better ceiling effect (0-29.0%), flooring effect (0); Cronbach’s α coefficient (0.92 to 0.98). The correlation coefficient between the original one and that of the short version one was 0.935. Conclusion: The short version of LDQOL has a higher reliability and good validity.
