Attachment across the lifespan: insights from adoptive families.

Research with adoptive families offers novel insights into longstanding questions about the significance of attachment across the lifespan. We illustrate this by reviewing adoption research addressing two of attachment theory's central ideas. First, studies of children who were adopted after experiencing severe adversity offer powerful tests of the unique consequences of experiences in early attachment relationships. Although children who experience early maltreatment or institutionalization show remarkable recovery in the quality of their attachments after being placed with their adoptive families, experiencing pre-adoptive adversity also has long-lasting repercussions for these individuals' later attachment representations. Second, adoptive families allow for genetically-informed examinations of the intergenerational transmission process. Indeed, despite the lack of genetic relatedness, adoptive parents' attachment representations are associated with their children's attachment behaviors and representations across childhood and adolescence.
