One hundred fourteen adult adoptees who had reunions with their birth parents responded to a mail questionnaire about these reunions. Some had been found by their birth parent, and others had searched for this parent. Those who searched were stimulated to do so by a life-cycle transition, by a need to get background information, and by a need to complete their sense of identity. For most of these adoptees, their self-esteem improved and their relationship with their adoptive parents was strengthened as a result of the reunion. These respondents advocate open adoption and better preparation for the adoptive family about adoptees' need to connect with their birth families.
