M.F. Janssen

Dr. M.F. Janssen is affiliated with the Department of Psychiatry at Erasmus MC. Their research focuses on psychometrics, quality of life assessment, and patient-reported outcomes in healthcare. They specialize in validating health measurement tools like the EQ-5D and MG-ADL across diverse populations and conditions, including myasthenia gravis, coeliac disease, and obstructive airway diseases. Their work emphasizes improving healthcare metrics through rigorous statistical validation and cross-cultural adaptation.

Recent research highlights include exploring cognition bolt-on items to EQ-5D for Chinese populations, analyzing gastrointestinal symptom impacts in coeliac disease, and evaluating anxiety/depression dimension correlations in large-scale mental health surveys. Their methodologies often integrate mixed methods and prospective data analysis to enhance the reliability of health economics instruments.

Janssen collaborates internationally, contributing to interdisciplinary projects that bridge clinical practice, public health, and statistical validation. Their publications reflect a strong focus on advancing outcome measurement in neurology, gastroenterology, and mental health domains.
