"This case study summarises an analysis conducted by Save the Children, UK using the Dioptra tool to assess the cost-efficiency of Psychosocial Support in Myanmar. The analysis revealed that: Psychosocial Support (PSS) in Myanmar cost between €14 to €54 per child reached. Delivering PSS through volunteers at mobile CFS is more cost-efficient than through fixed CFS, suggesting that it can be scaled up to address immediate needs. Leveraging on community volunteers and reutilising existing training materials may reduce costs and enhance efficiency. One-time infrastructure costs at fixed CFS are required to address children’s multidimensional needs, but such costs are expected to decrease in subsequent years..."
