W4E: WASH For Everyone: Testing Alternative Approaches to Sanitation and Hygiene Behaviour Change in Chiradzulu, Malawi
Study Details
Study Description
Brief 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.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: CLTS This arm will receive a standard community-led total sanitation) intervention). |
Other: Community-Led Total Sanitation
The community-led total sanitation intervention is implemented across an entire Traditional Authority and includes the following village-level activities:
Triggering:
Village transect walks and open defecation site mapping
Demonstrations of food contamination and medical expense calculations
Development of a Community-Action Plan and identification of "natural leaders"
Post-triggering: routine follow-up by selected natural leaders to track and monitor progress against the Community Action Plan
In addition to the activities above, the WASH for Everyone team will:
Train a cadre of local masons on sanitation construction
Support the District Health office in the implementation of existing sanitation and hygiene promotion at village markets and other public spaces
Other Names:

Outcome Measures
Primary Outcome Measures
- sanitation coverage [study endline (one year)]
Sanitation coverage is defined as confirmed presence of a functional sanitation facility in the home or compound that meets standard definitions of at least unimproved sanitation facilities according to the Joint Monitoring Programme. This will be determined by reported access to a private, household sanitation facility that respondents self-identify as completed. Self-reported access will be verified through visual inspection of the sanitation facilities.
Secondary Outcome Measures
- sanitation use [study endline (one year)]
Self-reported exclusive use of a sanitation facility for defecation among all members of a select households
- safe disposal of child feces [study endline (one year)]
Self-reported disposal of feces of any child under the age of five in a latrine / toilet
- handwashing facility [study endline (one year)]
presence of a dedicated device / location in the household were both soap and water are available for handwashing
- Basic sanitation coverage [study endline (one year)]
coverage: basic sanitation coverage is defined as the presence of a completed sanitation facility at the home that meets the minimum criteria of a basic sanitation facility, i.e. improved facility not shared with other households
- Sanitation-related Quality-of-Life (SANQoL) [study endline (one year)]
is a five-question instrument for measuring the degree of achievement of the following sanitation-related capabilities: privacy, safety, health, shame and disgust
- Handwashing behaviour [study endline (one year)]
observed handwashing with soap at critical moments (after defecation, cleaning a child and before cooking, eating, or feeding a child); measured through a three-hour direct observation in 50% of all study participants
