Implementation and sustainability of the Kizazi Kijacho trial parenting intervention
Complete
Mixed-method research combining a process evaluation (forthcoming), an endline evaluation, and a sustainability/scale-up study conducted 9–12 months after programme support ended. Evaluates what worked well and less well in terms of intervention delivery in practice, how (and why) the interventions changed caregiving practice, and what helped or hindered community health workers' delivery.
- Design
- Mixed-method
- Sample
- Quantitative data from 1,491 families participating in a Kizazi Kijacho parenting intervention, plus qualitative interviews and focus group discussions with a smaller sub-set of key stakeholders

Complete
A costing study estimating the resources required to deliver the parenting and cash-transfer interventions under the Kizazi Kijacho NGO-supported delivery model, examining the main cost drivers, how the cost burden is distributed among funding sources, and the incremental cost compared to existing services — to help inform decisions about future scale-up.
- Design
- Costing study, societal perspective
