3IE funded project
Despite evidence from various systematic reviews that water, sanitation and hygiene (WASH) interventions decrease morbidity from waterborne pathogens, a number of studies have shown that the impact falls over time. Sustainability of these interventions therefore remains an issue.
Goal of this project
To show which promotional approaches are effective to change handwashing and sanitation behaviour in low and middle income countries, and which implementing factors affect the success or failure of these promotional approaches.
This project is a collaboration between two centres: (1) the Centre for Evidence-Based Practice, Belgian Red Cross, Belgium; (2) the Centre for Evidence-Based Health Care, Stellenbosch University, South Africa.
In addition to representatives of both centres, the Project Team is completed with a WASH behaviour change expert, an information specialist, a statistician, and a qualitative research expert. We also composed an Advisory Group of different stakeholders, including WASH experts, policy makers, practitioners and a knowledge translator, in order to guarantee relevance for practice and implementation of our findings.
Oversight and guidance is provided by 3ie (International Initiative for Impact Evaluation), an international grant-making NGO promoting evidence-informed development policies and programmes, and by The Campbell Collaboration as review support group.
The project commenced by taking stock of existing systematic reviews (Phase 1). Following a comprehensive search we identified 6 systematic reviews. Using independent assessment and appraisal we developed an evidence gap map.
In the systematic reviews information on the promotional approach of the interventions was scarce, which identified the need for a new systematic review (Phase 2). The goal of this mixed methods systematic review, including both quantitative and qualitative evidence, is to show which promotional approaches are effective to change handwashing and sanitation behaviour, and which implementing factors affect the success or failure of these promotional approaches. The protocol for the systematic review can be found at the Campbell Library.
Stakeholder engagement will happen throughout the project and a stakeholder specific dissemination strategy will be used to communicate the findings of the project tailored to the requirements of these stakeholders.
