Adapting interventions to the context increases the impact and sustainability of interventions. Literature acknowledges the need to adapt existing interventions and that these adaptations should be clearly reported. However, little is known about how to incorporate adaptation from the beginning. This paper argues that interventions should be developed and adaptations should be made using an ongoing non-linear approach. An action-oriented research approach with feedback loops is proposed. We illustrate this with the development of a food literacy intervention 'Up for Cooking' (Dutch: Zin in Koken) and present lessons learned in developing, implementing and studying such adaptable interventions. Interventions should clearly define and differentiate the intervention function and form. Implementers, in turn, should be encouraged to tailor interventions within a form that fits with a specific context. Sufficient time, continuous adaptation based on co-creation, feedback loops and interdisciplinary collaboration are important prerequisites for the development of adaptable interventions., (© The Author(s) 2023.
