The civil war in Liberia killed around 10% of the population and displaced a majority. Even after more than 15 years of peace, the country is still suffering from the lasting impacts of its civil war, one of them being a permissive environment to violence in everyday lives. While violence against women and girls was systematically mobilized during the war, intimate partner violence (IPV) is highly prevalent in today's Liberia. To address IPV among a war-affected population, we conduct a randomized controlled trial with 1,200 disadvantaged women in Monrovia, Liberia. We evaluate the effectiveness of an unusually intensive female empowerment program that integrates psychosocial support with vocational training and business capital grants targeted towards marginalized women in slum communities.
