A negative relation was found between the mean score of CTP and the mean score of instrument (r=− 0.26, p<0.001). The test-retest reliability of instrument was found as 0.94 (ICC) p<0.01. The internal consistency Cronbach Alfa Coefficient of LDQOL 1.0 had good level and it was 0.80 Conclusion:. At the end of study “LDQOL 1.0” was found that it is very reliable and a valid instrument for Turkish society in chronic liver disease
