A program impact pathway analysis identifies critical steps in the implementation and utilization of a behavior change communication intervention promoting infant and child feeding practices in Bangladesh.

Mapping pathways of how interventions are implemented and utilized enables contextually grounded interpretation of results, differentiates poor design from poor implementation, and identifies factors that might influence the utilization of interventions. Few studies in nutrition have comprehensively examined the steps of implementation and utilization in behavior change communication (BCC) interventions, thus limiting the interpretation of variable impacts of BCC interventions. A program impact pathway (PIP) analysis was used to study a BCC intervention implemented in Bangladesh to improve infant and young child feeding (IYCF) practices.
