Effect of a Gender-Synchronized Family Planning Intervention on Inequitable Gender Norms in a Cluster Randomized Control Trial Among Husbands of Married Adolescent Girls in Dosso, Niger.

Gender inequitable norms have severe consequences for safety and health globally. Using data from a four-arm cluster randomized control trial of the Reaching Married Adolescents in Niger (RMA) intervention (2016-2019), this study assesses effects on gender norms among husbands of married adolescent girls (n = 1,055). Using an adjusted hierarchical difference-in-differences model, we found assignment to the RMA small groups intervention to be associated with a 0.62 decrease in inequitable gender norms (95% CI: -1.05, -0.18). As a cost-effective, scalable, and transferable intervention, this small group intervention could be valuable for reducing the negative impact of inequitable gender norms in similar settings.
