Study type | Interventional |
The objective of this research is to evaluate the impact of a multi-level behavior change intervention designed to promote toilet construction, exclusive toilet use and maintenance in peri-urban communities of Tamil Nadu. The intervention leverages two years of formative research and reflects a norms and network-centric approach that will employ dynamic information dissemination to signal others' sanitation practices while also addressing other barriers to the adoption of improved sanitation practices. The study will determine whether those who received the interventions had significant improvements in toilet usage compared to those who did not. Qualitative research will help assess exposure and reactions to the intervention in these communities.
