Aftercare services for international sex trafficking survivors: informing U.S. service and program development in an emerging practice area.

International sex trafficking into the United States appears to be a serious and growing problem, although the evidence regarding prevalence, risk, and consequences is incomplete. Nonetheless, human service providers are increasingly being asked to offer services to sex trafficking survivors. Consequently, providers need information to guide services and program development in this emerging practice area. To address this knowledge need, we systematically reviewed and synthesized 20 documents addressing the needs of and services for international survivors of sex trafficking into the United States. The main finding from the review shows the importance of a continuum of aftercare services to address survivors' changing needs as they move from initial freedom to recovery and independence. Based on our synthesis of the reviewed literature, we present a service delivery framework to guide providers' development of services for survivors.
