The Leuven Postprandial Distress Scale (LPDS) is the top patient-reported outcome measure for functional dyspepsia (FD) symptoms. Further research is needed to improve its cross-cultural validity and measurement error assessment.
Area of Science:
- Gastroenterology
- Clinical Outcome Assessment
- Psychometrics
Background:
- Functional dyspepsia (FD) is a disorder of brain-gut interaction (DBGI).
- Patient self-reporting is crucial for assessing FD symptoms and clinical outcomes.
- Identifying the best patient-reported outcome measure (PROM) for FD is essential.
Conclusions:
- LPDS is the most recommended PROM for patient-reported FD symptoms currently.
- LPDS requires improvement in assessing cross-cultural validity and measurement invariance.
- Further research should focus on enhancing LPDS to address its limitations.
