Young people labelled intellectually and/or developmentally disabled (ID/DD) who are making the transition to adulthood often lack control over their lives as restrictions are imposed upon their individual choices and their participation in decision-making. For those who have been wards of the child welfare system, this period of transition is made even more difficult by a history of child maltreatment, a lack of familial support, and a dearth of adult living arrangements available to them. Through face-to-face interviews with young adults with ID/DD upon leaving child welfare care, and through focus groups with members of the wider ‘community of interest’ (including child welfare social workers, adult protective service workers, foster parents, and residential services staff), this research examined the impacts of residential arrangements and a lack of housing placements upon both the situational and developmental transitioning of young people with ID/DD into adulthood. The consequences for the young person’s physical, mental, emotional and social well-being were related, in the discussions, to issues of choice and control, systemic barriers, devaluation, and rights. This paper focuses specifically on the themes of rights and well-being.
