Abstract

IntroductionFunctional dyspepsia (FD), affecting up to 29.2% of population worldwide, is defined as a condition in which dyspeptic symptoms occur in the epigastric region in the absence of an organic disease. At present, there are various scales to assess its symptoms and impacts. Of those, the quality of life questionnaire for functional digestive disorders (FDDQL), which aims to measure the pathology and symptoms of FD and irritable bowel syndrome with 8 domains and 43 items, has good scientific attributes. Until now, it has been translated into many languages: English, French, German, and others. In the previous study, the research group successfully translated it into mandarin language and found that it had good reliability, validity, responsibility, item test function, and differential item functioning characters.In spite of well‐established development of instruments, bias in interpreting health‐related quality of life scores may limit its use in clinical practice. As a limitation, we did not explain the clinical meaning of Chinese FDDQL (Chin‐FDDQL) in our previous study, which brought several problems: what exact information was provided with the test for doctors and patients, and how to make scientific clinical decisions? Clinical interpretation means “the degree to which one can assign easily understood meaning to
