Data collection tools and sample from Matlab and Habigonj, Bangladesh, 2010–2011

Data collection tools	Type of participant	Matlab (Primiparous mothers)	Habigonj (both primiparous and multiparous mothers)	Issues observed/explored
Observation (n = 40)	Mother of neonate < 28 days	20	20	Recorded several handwashing opportunities; handwashing opportunities were defined as critical times (before feeding or touching baby, after cleaning child’s bottom and after visiting the toilet) of possible pathogen transmission to or from mother’s hands. We recorded mother’s practices at these handwashing opportunities of the pre defined critical events and try to understand the contextual factors that facilitated or hampered their handwashing behaviors. During the sessions, we also recorded if anyone other than mothers touched or hold the child and their relevant handwashing behavior before the event
