Results show that young women reported that multiple placement moves within care were profoundly destabilizing. Their capacities to develop trusting relationships with others and feel settled were limited by frequent placement breakdowns, leading to a multitude of ways in which they became vulnerable to sexual exploitation through prostitution. The young women in the sample expressed how changes in career prevented them from forming bonds with adults associated with professional roles, and led them to developing relationships with older predatory men and peer networks that are embedded in the street prostitution community. The powerlessness that young women described from their lack of consultation over placement moves led them to seek ways to exercise their agency (power to act), even where this involved harmful environments. Becoming part of street prostitution communities and selling sex, generating income, and perceiving themselves as adults was perceived by young women as giving them the capacity to exercise personal power in their lives. This, combined with their distrust of care giving adults, often thwarts interventions. Understanding the destabilizing impact of placement moves on young women's attempts to express autonomy may offer practitioners a way to better engage with sexually exploited young women. Data were collected from 14 young women, aged 17-33 at the time of the interviews; all were selling sex on the streets by the age of 16, with 1 as young as 11. References
