The field research team will randomly select a subsample of caregivers of enrolled children for in-depth interviews and in-home observations, which will take place in the participants' home. In addition, the field research team will conduct focus group discussions with a smaller subsample of caregivers, to take place in a central and convenient location. The purpose of the in-home observations is to observe aspects of the family's preparation and consumption of the ration that they would be unlikely to be able to report during focus groups or individual interviews, because respondents may not be conscious of their actions. We will also collect data on behaviors, demographics and other factors contributing to effectiveness, including: ration collection, preparation, consumption, sharing, and selling behaviors, knowledge and communication of social and behavior change communication (SBCC) messages regarding ration use among health workers and beneficiary mothers, other health behaviors such as breastfeeding, dietary diversity and hygiene practices, and demographics such as household food insecurity and number of young children. All interviews, observations, and focus group discussions will be administered by trained research assistants. The team will also conduct interviews with community health volunteers working in the PHUs and the catchment villages they serve.
