The design of this study was guided by a Technical Advisory Committee comprising representatives from the Ministry of Health and Family Welfare, Government of India, non governmental organisations and academic institutions. UDAYA uses both cross-sectional and longitudinal surveys and qualitative studies.
The cross-sectional component involves interviewing a fresh sample of unmarried girls and boys aged 10–14 and 15–19, and married girls aged 15–19 in 2015 and 2018 in both Bihar and Uttar Pradesh. In the first phase of the study, which was done in 2015-16, 10,433 adolescents in Bihar and 10,141 adolescents in Uttar Pradesh were interviewed.
The longitudinal component involves re-interviewing the sample of unmarried girls and boys and married girls aged 15–19 interviewed in 2007, as part of the original Youth Study, in 2015 in Bihar; and re-interviewing in 2018 in Bihar and UP the sample of unmarried girls and boys aged 10–14 and 15–19 and married girls aged 15–19 who were interviewed in 2015.
In addition, four quantitative or qualitative studies of policy/programme relevance will be conducted, with topics to be determined jointly with stakeholders.
