简要总结
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.

研究组 & 干预措施
Experience Sampling Method (ESM)
Both patients with functional dyspepsia and healthy controls will be asked to fill out ESM questionnaires during 1 week. Moreover, at the end of this week, usual questionnaires for complaints assessment will be filled out.
干预措施: Experience Sampling Method (ESM) (Other)
结局指标
主要结局
Change in experience sampling method (ESM) scores
时间窗: 10 times daily, during 1 week
Using the MEASuRE-D app, the same ESM questionnaire will be filled in 10 times per day at random intervals. This results in a lot of real-time data on patient symptom scores on which changes over the course of the day can be seen.
Patient complaint diary
时间窗: End of day 1, end of day 2, end of day 3, end of day 4, end of day 5, end of day 6, end of day 7
Using the MEASuRE-D app, patients will fill out a complaints diary at the end of each day during 7 days
次要结局
- Questionnaire for demographic characteristics(On day 7)
- PAGI-SYM questionnaire(On day 7)
- NDI questionnaire(On day 7)
- GSRS questionnaire(On day 7)
- PHQ-9 questionnaire(On day 7)
- GAD-7 questionnaire(On day 7)
- PHQ-15 questionnaire(On day 7)
- SF-36 questionnaire(On day 7)
