Background and aims-To develop and assess a disease specific instrument for measuring health related quality of life (HRQL) in patients with chronic liver disease (CLD).
Methods-Based on responses from 60 patients with chronic liver disease, from 20 liver experts, and from a Medline search of the literature, items potentially affecting the HRQL of these patients were identified.
A separate sample of 75 patients identified which items they found problematic and rated their importance.
Results were explored using factor analysis ; domains were chosen and items placed within domains.
Redundant questions were eliminated and the final questionnaire was pretested in 10 patients.
Using this instrument, HRQL was assessed in a further 133 patients with various types and stages of liver disease.
Patients, experts, and the literature search identified 156 items of potential importance.
Of these, 35 proved important to over 50% of 75 respondents in the item reduction sample.
After eliminating redundancies, the Chronic Liver Disease Questionnaire (CLDQ) included 29 items in the following domains : fatigue, activity, emotional function, abdominal symptoms, systemic symptoms, and worry.
In pretesting, patients found the CLDQ clear and easy to complete in 10 minutes.
In another 133 patients, the CLDQ showed a gradient between patients without cirrhosis, Child's A cirrhosis, and those with Child's B or C cirrhosis. (...)
