Abstract
BACKGROUND
Gastroesophageal Reflux Disease Questionnaire (GERDQ) and Quality of Life in Reflux and Dyspepsia Questionnaire (QOLRAD) are reliable tools for evaluation of GERD.
AIM
We aimed to test validity and reliability of Malay language translations of GERDQ and QOLRAD in a primary care setting.
METHODS
The questionnaires were first translated into the Malay language (GERDQ-M and QOLRAD-M). Patients from primary care clinics with suspected GERD were recruited to complete GERDQ-M, QOLRAD-M, and Malay-translated 36-item short-form health survey (SF-36 or SF-36-M), and underwent endoscopy and 24-h pH-impedance test.
RESULTS
A total of 104 (mean age 47.1 years, women 51.9%) participants were enrolled. The sensitivity and specificity for GERDQ-M cut-off score ≥8 were 90.2 and 77.4%, respectively. Based on this cut-off score, 54.7% had a high probability of GERD diagnosis. GERD-M score ≥8 vs. < 8 was associated with erosive esophagitis (p < 0.001), hiatus hernia (p = 0.03), greater DeMeester score (p = 0.001), and Zerbib scores for acid refluxes (p < 0.001) but not non-acid refluxes (p = 0.1). Mean total scores of QOLRAD-M and SF-36-M were correlated (r = 0.74, p < 0.001). GERDQ-M ≥8, erosive esophagitis, and DeMeester ≥14.72 were associated with impaired QOLRAD-M in all domains (all p < 0.02) but this was not seen with SF-36.
CONCLUSIONS
GERDQ-M and QOLRAD-M are valid and reliable tools applicable in a primary care setting.
