Validation of RDQ Questionnaire

Summary

The primary objective of this study is to determine the accuracy of the Reflux Disease Questionnaire (RDQ) as a diagnostic test for gastroesophageal reflux disease. Symptom evaluation by the RDQ will be compared with other established approaches to the diagnosis of gastroesophageal reflux disease (GERD) in a primary care patient population with symptoms thought to be of upper gastrointestinal (GI) tract origin.
