5. Study Description

Brief Summary
Develop a scalable approach for delivering water, sanitation, and hygiene (WASH) messages to households in areas with confirmed cholera patients in Dhaka, Bangladesh. This will be done by conducting formative research through in-depth interviews, focus group discussions, and intervention planning workshops with households in areas with confirmed cholera patients and government officials to identify perceptions of WASH behaviors and to inform the development of a mobile health intervention (mHealth) for this population. This intervention approach will then be piloted in a subset of households, and revised according to feedback. Then the investigators will conduct a randomized controlled of the refined mHealth intervention.
Detailed Description
Aim 1. Develop an evidence and theory based WASH mHealth intervention for households in areas with confirmed cholera patients in Dhaka, Bangladesh through formative research Conduct formative research through in-depth interviews, focus group discussions, and intervention planning workshops with caregivers and household members of young children, and government officials to identify perceptions of WASH behaviors and to inform the development of intervention materials. Pilot the WASH mHealth intervention in a subset of households, and revise according to feedback. Aim 2: Evaluate the effectiveness of the developed WASH mHealth intervention in increasing WASH behaviors and reducing fecal contamination on hands and in stored drinking water by conducting a RCT Recruit and prospectively follow for 12 months 120 households (600 participants, 4 per household) with a child under five years of age assigned to one of two study arms (60 households per arm). The first arm will receive the CHoBI7 mHealth program (CHoBI7 mHealth program Arm) and the second arm will serve as a Control Arm and only receive a general message on oral rehydration solution (ORS). Compare the 2 study arms using structured observation of handwashing with soap at stool and food related events, unannounced spot checks of the presence of soap in the cooking and latrine areas of the household, and fecal coliform counts on caregiver hands and in stored drinking water.
