Learning from previous programmes & existing literature for effective interventions

– Be rooted in behaviour change theories & not being too general

– Identify and target specific behaviours and their determinants

– Take into account stakeholders’ views, contextual factors and policy framework

– Target school and home social & physical environment

– Have a minimum duration of one academic year

– Be low in cost and use available human and infrastructure resources

– Perform a process evaluation
