The problem
Intervention: Tipping Point Initiative: combined program with weekly single-gender group sessions for adolescents (12-16 years) and monthly parental sessions; TPP+ arm additionally included cross-gender and cross-generation dialogues, girls' movement building, and girl-led community sensitisation
Who it was tested with: Never-married adolescent girls and boys aged 12-16 and their parents in rural villages of a sub-district in Bangladesh.
Children or communities are compared with a group that did not receive the intervention, or followed over years. This is the design that best separates what the intervention did from everything else that changed.
"A three-arm non-blinded Cluster Randomised Controlled Trial was conducted in 51 villages/clusters in a sub-district of Bangladesh. Clusters were randomly assigned to the arms: Tipping Point Program (TPP), Tipping Point Program Plus (TPP+), and Pure Control." The study used a rigorous experimental design with random assignment of clusters, blinded analysis with hazard ratios, and intention-to-treat methodology, meeting the criteria for EXPERIMENTAL tier evidence.
No intention-to-treat effect detected at full sample level, suggesting implementation challenges or low engagement. COVID-19 disruptions affected program delivery. The dose-response finding (high attendance showing benefit) indicates the intervention may have potential but requires improved implementation or engagement strategies.
