However, they have in common that they are filling the gap care and support provisions that the government has left behind. In order to get a better image of this movement, their impact and the challenges they face in collaborating with the Dutch care system, Vilans and the Dutch umbrella organization of citizens initiatives (NLZVE) bundled their forces in a variety of research projects. This collaboration started in 2020 with the ‘Monitor on the Movement of Caring Communities’. In co-creation with key figures from the movement of caring communities we developed a survey. The results of this survey (n=346) gave us insight in the activities, goals, partners and bottlenecks of these initiatives and initiated new participatory action research projects.

Simultaneously we found that many initiatives struggle to show their impact. This impact is often implied (i.e. less loneliness or a healthier population) but hardly mapped. We found that the lack of a clear message ...
