Grotevant, however, sounded a note of caution to those who portray it as a panacea. The children of open adoption do not have higher self-esteem than those in closed adoptions, he observed. For children in each group, self-esteem is about the same, his research found. He stressed that more research is needed to assess the impact of open adoption on adolescents. (The research he did with McRoy studies children up to age 12.)
In all adoption searches, it is uncommon to find both the birth mother and father at the same time. A separate search, if desired, can be done afterwards for the father. Since males seldom change their surnames, and the mother might have additional information, it is usually easier than the initial search for the birth mother. In many cases, adoptees are able to do this second search for their birth father by themselves (or they try before paying for assistance).
