Abstract
In light of the poor prospects facing many former foster youth during the transition to adulthood, it is surprising that so little attention has been given to substitute care contexts during child welfare system involvement. A review of child welfare research finds that many former foster youth go through an alarming number of placement changes and report a high rate of placement into congregate care settings and other unplanned events. Future research should take explicit account of substitute care contexts in designing and carrying out studies examining the adult outcomes of aging out foster care populations. Interventions intended to circumvent high rates of movement in foster care should also be broadened to target multiple aspects of substitute care contexts.
