The usefulness of theory to inform and guide health behaviour interventions cannot be underestimated. While the intervention was not planned and implemented using a specific theory a priori, the intervention has been de- scribed [32] according to Kok and colleagues’ work [41] on Intervention Mapping: The theory describes a flow for implementation originating from proximal programmes through the development of strategies, programme plans, adaption and evaluation. This flow is implying certain consecutive tasks. In our case the initial step was the WHO course which was adapted by the research team and through local knowledge (research team in collab- oration with the communities) moderated and opera- tionalised.
