families, and as the venue for some of the intervention
components. Each component has fixed parameters as
well as elements that allow tailoring to specific populations,
enabling schools to adapt the delivery by taking
account of local circumstances. Relevant school staff
members are provided with a manual and a short training
session on delivering the intervention. Follow-up support
for intervention delivery is provided by research staff in
the first few weeks. No further support is provided for the
remaining intervention period.
Schools in the intervention arm receive reimbursement
(£380) to cover costs incurred through their involvement
with the intervention (such as staff cover for teacher
training).
