On the 30th of November, WP2 organized an expert meeting in Rotterdam on urban environments and mental wellbeing at older ages for the further development of the conceptual model. A group of thirteen experts from different countries and different research fields joined this meeting. All experts started with an overview of the state-of-the-art in their field of research relating to the pathways through which the urban environment can influence mental wellbeing at older age. This was followed by a fruitful discussion on how to integrate these pathways. The knowledge gathered and produced in this meeting will be integrated into the next version of the MINDMAP conceptual model.
