“Bridging the Divide: Openness in Adoption and Post-adoption Psychosocial Adjustment among Birth and Adoptive Parents”- How does Open Adoption affect adopted children, adoptive parents, and birth mothers. Journal of Family Psychology, 2008.
Research on 323 matched pairs of birth mothers and adoptive parents looked at the association between the degree of openness in the adoption and the satisfaction as measured within 6 to 9 months post adoption. They found that openness was significantly related to the degree of satisfaction expressed by both adoptive parents and birth parents. 112 birth fathers were also interviewed, and those in open adoptions were more satisfied with the process and had better post adoption adjustment.
