This journal article presents a qualitative study of 32 cases of young people who were sex trafficked as minors. The author reviews their cases for histories of early adversity and polyvictimization and any common coercive strategies of traffickers, including manipulation of the victims’ unmet physical and emotional needs. The study describes developmental trauma adaptations in these youth, including affect dysregulation and impulsivity; changes in attention and consciousness; interpersonal relationship issues; and impairments in self-perception and attributions. Based on these findings, the author recommends developmentally and culturally appropriate trauma-informed services for sex trafficked children and youth.
