EMGO+ puts much emphasis on promoting and maintaining high quality standards in its research. First of all, EMGO+ invests in research methodology expertise and development, this especially concerns the topics of clinimetrics (Riekie de Vet, Caroline Terwee, Raymond Ostelo, Dirk Knol), Health Technology Assessment (HTA) (Maurits van Tulder, Raymond Ostelo), prognosis and prediction research (Daniëlle van der Windt, Martijn Heymans, Riekie de Vet) and longitudinal data analysis (Jos Twisk, Martijn Heymans). Furthermore, EMGO+ has developed and maintains a quality handbook that guides all research conducted within the institute supported by a quality committee. EMGO+ also has an internal Science Committee and an external Advisory Board that advices the directorate on its scientific policy. The Science Committee also assists in improving research proposals.
