ESM in Functional Dyspepsia

Netherlands72 participantsStarted 2020-05-29

Plain-language summary

Background: Reliable patient reported outcome measures (PROM's) for symptom assessment in functional dyspepsia (FD) are essential in order to evaluate dyspeptic symptoms, identify potential symptom triggers and optimize therapeutic strategies, since biological markers are unavailable. Currently used symptom assessment methods, i.e. end-of-day or end-of-week questionnaires, have considerable limitations. The Experience Sampling Method (ESM), an electronic questioning method characterized by random and repeated, momentary assessments in the subject's current state and environment, might overcome these limitations. The aim of this study is to assess the validity and reliability of an FD-specific electronic patient-reported outcome measure (ePRO), based on the Experience Sampling Method-principle, for symptom assessment and identification of symptom triggers in patients with functional dyspepsia. Objective: The aim of this study is to assess the validity and reliability of an FD-specific electronic patient-reported outcome measure (ePRO), based on the Experience Sampling Method-principle, for symptom assessment and identification of symptom triggers in patients with functional dyspepsia. In order to measure this, internal consistency, test-retest reliability, concurrent validity and the accuracy to differentiate between dyspeptic patients and healthy controls of the developed ePRO will be assessed. In addition, to objectify specific triggers for the onset of gastrointestinal symptoms in dyspepsia, using the FD-specific ESM tool.
