Randomized Controlled Trial Multicenter Study Clinical TrialValidation of the GSFQ, a self-administered symptom frequency questionnaire for patients with gastroesophageal reflux disease.
Although the diagnosis of gastroesophageal reflux disease (GERD) is based primarily on symptoms experienced by a patient, relatively little attention has been paid to the development and validation of self-administered questionnaires specific to GERD symptoms. The present article presents the validation of the short, self-administered GERD Symptom Frequency Questionnaire (GSFQ). ⋯ The GSFQ is a short, self-administered, easy to use, GERD-specific questionnaire which should be considered as a useful assessment tool in the evaluation of patients with GERD and in the assessment of treatment outcomes.
