The Norms and Networks Sanitation Study in India in Tamil Nadu, India — LENNS  

Behavior, Social Clinical Trial

Official title: The Longitudinal Evaluation of Norms and Networks Study: A Cluster Randomized Controlled Trial to Promote Exclusive Toilet Use in Tamil Nadu, India

Status Completed

Clinical Trial 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.

Clinical Trial Description

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.

For this cluster-randomized trial, communities will be engaged in two rounds of surveys to assess toilet ownership, toilet usage practices of their family members and include additional questions about beliefs, norms and other factors influencing toilet use. Investigators will also conduct a process evaluation to monitor change from baseline to endline and identify successful pathways of or bottle-necks to the adoption of improved sanitation behaviors. These indicators will include fidelity indicators to assess the quality of intervention delivery, level of community participation, behavioral antecedents, contextual changes in community and household conditions that may facilitate improved behavioral adoption and/or outcomes (e.g., exclusive toilet use). They will also conduct qualitative research using observations and semi-structured interviews with respondents and stakeholders to assess exposure and reactions to the intervention. They will also assess spillover in the control wards using mixed-method assessment tools. ;
