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.)
On June 1, 2009, Ontario, Canada, opened its sealed records to adoptees and their birth parents, with a minimum age of 18 for the adoptee, or one additional year if the birth parents initiate the request. Both parties can protect their privacy by giving notice of how to be either contacted or not, and if the latter, with identifying information being released or not. All adoptions subsequent to September 1, 2008, will be "open adoptions"
Open adoption is a form of adoption in which the biological and adoptive families have access to varying degrees of each other's personal information and have an option of contact. While open adoption is a relatively new phenomenon in the west, it has been a traditional practice in many Asian societies, especially in South Asia, for many centuries. In Hindu society, for example, it is relatively common for a childless couple to adopt the second or later son of the husband's brother when the childless couple has limited hope of producing their own child.
