In the Healthy Start convergence, we mainly contribute to Ambition 6, which focuses on increasing involvement and participation of (unheard of) young people in society. Esther Rozendaal is part of the core team, investigating what works best to actively involve youth in youth participation projects. Together with Chiara de Jong, Kim Doornhein and Ying Chuck, she is also involved in a Healthy Start Sprint project on the development of a tool for child-participation regarding intervention development in the context of (digital) resilience.
