Attachment theory, first proposed by John Bowlby in the early 20th century, supports the idea that how a child is treated by his or her parents will have a long lasting impact on the child's ability to participate in meaningful relationships. Adult attachment theory, as proposed by Hazan & Shaver, Bartholomew & Horowitz, and other researchers in the 1980s and 1990s, extended the original model to romantic relationships.
Support for the link between childhood attachment status and adult attachment status has been difficult to attain. Longitudinal research conducted at the University of Minnesota is helping to bridge that gap.
