Table 4 The five RE-AIM (reach, efficacy/effectiveness, adoption, implementation, maintenance) dimensions and how these dimensions were planned to be measured through several components at different levels in the DAGIS intervention study

From: Development of the DAGIS intervention study: a preschool-based family-involving study promoting preschoolers’ energy balance-related behaviours and self-regulation skills
