Validity and Reliability Test of Rome IV Functional Dyspepsia Diagnostic Questionnaire (R4-FDDQ) on Indonesian Population

Abstract

Introduction: Currently there has not been a specific instrument to assess the presence of functional dyspepsia, which is specially designed for the Indonesian population. The main objective was to determine the validity and reliability of the Indonesian version of the Rome IV Functional Dyspepsia (FD) Questionnaire Criteria. Methods: A total of 80 participants (age ≥21 years) with a complaint of dyspepsia were recruited. The Kruskal-Wallis test is used to analyze the difference between demographic data and the type of FD. Pearson’s product-moment correlation and Cronbach’s alpha tests were used to assess the validity and reliability.
