The "Endline Assessment on Knowledge around Menstrual Health & Hygiene among Adolescent Girls in Select Districts of Assam Using Digital Content and Media," conducted by the Centre for Catalyzing Change (C3) in 2021, evaluated the impact of digital media-based programs aimed at building life skills and self-confidence among adolescents. The study focused on enhancing knowledge of sexual and reproductive health and rights among adolescent girls in Kamrup, Dhubri, and Nagaon districts of Assam. By using a quasi-experimental research design, the study compared the knowledge, attitudes, and practices of 450 adolescent girls (unmarried girls aged 10-14 and 15-19, and married girls aged 15-21) across intervention and non-intervention villages.
