Brief summary: BACKGROUND. Diarrhea is ubiquitous, particularly among people in low- and middle-income countries. Unsafe drinking water, poor sanitation, and insufficient hygiene are responsible for nearly 90% of diarrhea-related mortalities. Despite extensive knowledge that has been obtained in recent years, there is no consensus as to the most efficacious approach to improve Water, Sanitation, and Hygiene behavior and health. With this study, we want to determine whether multi-faceted contextualized and non-contextualized WASH interventions have a differential impact.

OBJECTIVES. The primary objective is to determine the effectiveness of a contextualized and non-contextualized add-on intervention for improving hand washing (HW) behavior. Secondary objectives include the impact on latrine use, health, coverage of HW and latrine infrastructure, quality of life, and cost-effectiveness.


Eligibility criteria: Inclusion Criteria:

* All people above 18 years of age.

Exclusion Criteria:

-

Primary outcomes:
measure: Change in hand washing behavior
timeFrame: The outcome is measured at baseline, and after 1 and 2 years of intervention. In addition, a measurement will occur 1 year after the intervention has finished to see whether improvements have been maintained.
Secondary outcomes:
measure: Change in latrine use behavior
timeFrame: The outcome is measured at baseline, and after 1 and 2 years of intervention. In addition, a measurement will occur 1 year after the intervention has finished to see whether improvements have been maintained.
measure: Quality of the hand washing infrastructure
timeFrame: The outcome is measured at baseline, and after 1 and 2 years of intervention. In addition, a measurement will occur 1 year after the intervention has finished to see whether improvements have been maintained.
measure: Change in health
timeFrame: The outcome is measured at baseline, and after 1 and 2 years of intervention. In addition, a measurement will occur 1 year after the intervention has finished to see whether improvements have been maintained.
measure: Change in EQ-5D-3L
timeFrame: The outcome is measured at baseline, and after 1 and 2 years of intervention. In addition, a measurement will occur 1 year after the intervention has finished to see whether improvements have been maintained.
measure: Quality of the latrine infrastructure
timeFrame: The outcome is measured at baseline, and after 1 and 2 years of intervention. In addition, a measurement will occur 1 year after the intervention has finished to see whether improvements have been maintained.
