The problem
Intervention: Girls Invest, an app-based economic empowerment intervention teaching financial decision-making, gender equity, and healthy relationships to girls aged 15-19
Who it was tested with: Adolescent girls aged 15-19 in low-income communities in Ibadan, Nigeria (n = 258, predominantly Yoruba, mostly Muslim).
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.
"We conducted a 2-armed randomized-controlled trial (16 schools, 8 schools per arm) among girls ages 15–19 (n = 258) to compare the Girls Invest intervention to a wait-list control condition on social and economic risk factors associated with IPV. Quantitative analyses compared survey data at baseline and 6 months follow-up using a difference-in-differences approach." This design with randomization to intervention or control arm and multiple follow-up timepoints constitutes an experimental evaluation that can assess causality.
Study has modest sample size and geographic limitation to one Nigerian city. Primary outcome of actual intimate partner violence incidence was not measured; study focused on intermediate risk factors. Follow-up was only 6 months. Authors note full-scale trial is still needed.
