Validity and reliability study of the chronic liver disease questionnaire

Objective: The aim of this study was to adapt of the Chronic Liver Disease Scale to Turkish and determine the validity and realibility of the scale. Method: This methodological study was conducted between November 24, 2016 and April 5, 2017 at the Gastroenterology Clinic and Gastroenterology Policlinic of the Akdeniz University Hospital with 235 chronic liver patients. "Personal Information Form", "Child-Pugh Scoring System Form", "Chronic Liver Disease Questionnaire (CLDQ)" and "Chronic Liver Disease Quality of Life Scale 2.0" were used as data collection tools. Results: In evaluating the validity analysis; scope validity, validity according to a reference, structure validity methods were used. As a result of the validity analysis, it was determined that the scale consists of six sub-dimensions. There was no substance removed from the original scale. In evaluating the reliability analysis, internal consistency, invariance, assessment of substance analyzes was used. The overall Cronbach alpha coefficient of the scale was 0.95, and the Cronbach alpha values of the subscales ranged from 0.53 to 0.94. In the internal consistency evaluation, the correlation coefficient between the two applications (r = 0.79) was found to be high in the test re-test analysis results. When substance analyzes were examined, it was found that the mean of the substances were close to each other, when the average of the upper and lower groups were examined, the discriminatory properties of the substances were high and the behaviors to be measured in the symptoms of chronic liver diseases were found to be reliable. Conclusion: The Chronic Liver Disease Scale was a valid and reliable tool to measure the quality of life of chronic liver disease patients by determining the frequency of symptoms in chronic liver diseases. It was suggested that the Turkish version of the Chronic Liver Disease Scale should be be used in symptomatic evaluation of chronic liver disease.
