In this paper published in Intervention, the authors describe community based, participatory action research (PAR), an innovative field practice that meaningfully involved young mothers formerly associated with armed groups and other vulnerable young mothers in their communities. The project took place in 20 field sites in three countries: Liberia, northern Uganda and Sierra Leone. Some project outcomes included: young mothers and their children experiencing improved social reintegration evidenced by greater family and community acceptance; more positive coping skills; and decreased participation in sex work for economic survival.
