Post emergence of COVID-19 pandemic, CMS as a long term research partner to UNICEF, under Humanitarian Programme, is regularly providing technical expertise for research and analysis of behavioural insights on interventions covering different aspects of major issues such as COVID-19, Routine Immunization, Breastfeeding and social protection programmes of the government. Three rounds of annual assessments, starting with Baseline (2021), Midterm (2022) and Endline (2023), was conducted across 11 states to capture data and information from the rural locations, primarily inhabited by the marginalised communities namely, dalits (SCs), adivasis (STs), denotified tribes (DNTs), and minorities (mainly Muslims). Further to enhance the capacity of local youth to undertake research surveys, CMS engaged a mix of female and male volunteers of Praxis NGO network partners along with professional research enumerators from respective states for the data collection. The team members were oriented using virtual platforms to conduct CAPI based survey using a multi-lingual survey instrument. As a way forward the findings and key takeaways were shared with UNICEF team at national and state offices for communication & advocacy with respective state functionaries.
