Dyspepsia Clinical Trial
Official title:
The Experience Sampling Method (ESM): Validation of a Newly Developed Real-time Patient-Reported Outcome Measure (PROM) and Its Evaluation of Triggers for Functional Dyspepsia
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.
