Brief Summary
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.

Intervention Group
EXPERIMENTALResidents of the peri-urban ward randomized to this group will receive the norm and network-centric intervention package that includes individual, household, group and community-level interventions. No hardware will be provided. Behavior change components will focus on shifting empirical expectations of improved sanitation behaviors in their wards as well as building capacity to achieve toilet construction and behavioral goals.
Control Group
NO INTERVENTIONResidents of these wards will not receive any intervention. They may be exposed to other WASH interventions promoted by the government and/or other parties independent of this study.
