Summary

This study aims to assess the impact of multiple community-based behaviour change approaches on sanitation and hygiene behaviours in rural Malawi. Three different sub-districts (Traditional Authorities) in Chiradzulu District will be selected, each receiving a different combination of community-based interventions or will serve as controls. Eligible communities, households, and individuals will be randomly selected in each Traditional Authority and sanitation and hygiene behaviours assessed through self-report and direct observation after 1 year of intervention.

Detailed description

This is a controlled before-and-after study that will evaluate the impact on sanitation and hygiene behaviours of different community-based interventions implemented as part of the WASH For Everyone programme. WASH for Everyone, implemented by World Vision and Water For People. WASH for Everyone is a 3-year project (2022 - 2024) that aims to achieve universal access to water, sanitation, and hygiene (WASH) in Chiradzulu district, and promote improved sanitation and hygiene behaviours. There are two primary community-based sanitation and hygiene behaviour change approaches included in the WASH for Everyone interventions: 1) community-led total sanitation (CLTS), a widely implemented participatory approach to ending open defecation at the community-level and 2) Care Groups, a model using locally-based volunteer groups to implement peer-to-peer counselling and support with a long history in nutrition programming. For the purposes of this study, one Traditional Authority will receive the CLTS intervention. A second Traditional Authority will receive the CLTS intervention with the additional of village-level Care Groups (CLTS +). A third traditional authority will serve as the comparison group. Within study Traditional Authorities, communities will be selected at random for inclusion in the study. Twenty communities will be enrolled in both the CLTS and the CLTS+ Traditional Authorities. Thirty communities will be enrolled from the comparison Traditional Authority. In each selected community, an average of 20 households will be enrolled at baseline and again at endline. Difference-in-difference analysis will be used to measure the changes in primary and secondary outcomes between either intervention and control and between the two intervention groups.
