PATH Kenya is an organization that designs and implements innovative solutions to complex health challenges and strengthens health systems. Its Living Labs program uses human-centered approaches to co-create effective interventions. As part of the Zero-Dose Learning Agenda (ZDLA), PATH has been delivering Chanjo Talks Kazini (CTK)—an intervention targeting male caregivers of under-one children in Homa Bay County, Kenya. CTK brings group sensitization sessions to male caregivers at their workplaces and in key community spaces. We’re working with PATH to assess the impact this intervention has had on trust among households, based on a new data collection tool: the Conversational Trust Tool.
