Abstract
Objective: Gastroesophageal reflux is a disease that is common in society and affects quality of life. The aim of the present study was to test the validity and reliability of the Turkish version of the Gastroesophageal Reflux Disease Quality of Life scale.
 Methods: A total of 161 patients with gastroesophageal reflux disease who applied to the gastroenterology outpatient department of a university hospital between July 2017 – October 2017 constituted the sample of this study. The study was a methodological and descriptive study. In the validity and reliability studies, the language validity, content validity, internal consistency (Cronbach’s alpha reliability coefficient) and confirmatory factor analysis methods were used.
 Results: The Cronbach’s alpha reliability coefficient of the Gastroesophageal Reflux Disease Quality of Life scale was α = 0.885, while its content validity ranged between 0.84-0.92. According to confirmatory factor analysis, the 4-factor structure of the scale, consisting of 16 items, generally had good fit.
 Conclusion: The Turkish version of the Gastroesophageal Reflux Disease Quality of Life scale was found to be a valid and reliable scale that can be used to measure the quality of life of individuals diagnosed with gastroesophageal reflux disease.
