From maternal sensitivity in infancy to adult attachment representations: a longitudinal adoption study with secure base scripts.

We examined whether differences in adult attachment representations could be predicted from early and later maternal sensitivity, controlling for early and later assessments of attachment. In this longitudinal study on 190 adoptees, attachment at 23 years was measured with the Attachment Script Assessment. Maternal sensitivity was observed in infancy and at seven and 14 years. Attachment was also measured in infancy and at 14 years. Higher maternal sensitivity in infancy predicted more secure attachment in infancy and more secure attachment representations in young adulthood. Higher maternal sensitivity in middle childhood also predicted more secure attachment representations in young adulthood. There was no continuity of attachment from infancy to young adulthood, but attachment in adolescence and young adulthood were significantly related. Even in genetically unrelated families, maternal sensitivity in early and middle childhood predicts attachment representations in young adults, confirming the importance of sensitive parenting for human development.
