Our commentary highlights the authors' conceptual and empirical contributions for understanding the incidence and dynamics of varying types of adoption breakdowns and their impact on adopted youth and their families. Important distinctions are made between legal, residential, and psychological/relational permanence for children. To date, most research has focused on factors supporting or undermining legal and residential permanence but has largely ignored children's sense of psychological or relational permanence. Recommendations for future research and implications of findings for policy and practice are discussed.
