The intergenerational transmission of attachment during middle childhood in lesbian, gay, and heterosexual parent families through assisted reproduction: The mediating role of reflective functioning

The pioneering longitudinal studies of child development (all launched in the 1920s and 1930s) were extended well beyond childhood. Indeed, they eventually followed their young study members up to the middle years and later life. In doing so, they generated issues that could not be addressed satisfactorily by available theories. These include the recognition that individual lives are influenced by their ever-changing historical context, that the study of human lives calls for new ways of thinking about their pattern and dynamic, and that concepts of human development should apply to processes across the life span. Life course theory has evolved since the 1960s through programmatic efforts to address such issues.

While strong retrospective and concurrent associations between maternal and infant patterns of attachment have been noted, this is one of the first reports of a prospective investigation of such associations. The Adult Attachment Interview was administered to 100 mothers expecting their first child, and, at 1-year follow-up, 96 of these were seen with their infants at 12 months in the Strange Situation. Maternal representations of attachment (autonomous vs. dismissing or preoccupied) predicted subsequent infant-mother attachment patterns (secure vs. insecure) 75% of the time. These observed concordances, as well as the discordances, are discussed in terms of the uniquely powerful contribution the Adult Attachment Interview makes to the study of representational and intergenerational influences on the development of the infant-mother attachment.
