Qualitative and process evaluation assessments Linked qualitative methods will be used to develop and validate data collection measures (pilot) and to add depth and understanding of process and outcomes. During the randomized trial stages, they will explore caregivers' and implementers' experiences in the program and how service delivery, socio-economic, cultural, and other factors may impact the effectiveness and scalability of the intervention. Qualitative methods (in Bahasa and Sundanese) include semi-structured interviews with caregivers, implementers (Save the Children/NGO staff, mentors, and facilitators) and community leaders; focus group interviews with participating caregivers and implementers; observation of group sessions; record analysis; and visual methods.
