Promoting handwashing and sanitation behaviour change in low-and middle-income countries
This report by 3ie summarises a systematic review by De Buck and colleagues that examines which promotional approaches are effective in changing handwashing and sanitation behaviour and which implementation factors affect the success or failure of such interventions. The study is the first mixed methods systematic review of behaviour change in sanitation and hygiene, drawing on quantitative and qualitative evidence. It shows that CLTS, in comparison with approaches like social marketing and health messaging, is most effective in improving OD behaviour and latrine use.
