The global study, Invisible Women: Gendered Dimensions of Return, Reintegration and Rehabilitation, conducted in partnership with the International Civil Society Action Network, responds to a pressing need for action-oriented research that improves our understanding of women’s roles in reintegration and rehabilitation processes, and the work of women-led organizations in supporting these processes. The study considers their experiences as critical lessons for the design and implementation of initiatives to prevent violent extremism. In doing so, it makes an important contribution to an expanding evidence base on the reintegration of violent extremists.
