This book highlights a report to Congress which outlines the findings of two adoption-research studies conducted as part of The Collaboration to AdoptUsKids. In the first study, a nationwide purposive sample of 300 families seeking to adopt children with special needs from the public child welfare system was selected, interviewed and surveyed to determine actual and potential barriers to the completion of the adoption process. In the second study, a four-year prospective examination of a nationwide sample of 161 families who had adopted children with special needs was conducted in order to determine factors that contributed to successful adoption outcomes.
