Mary Main (1943-2023) was an American developmental psychologist, a direct student of Mary Ainsworth, and a central figure in contemporary attachment theory. Her two fundamental contributions were: identifying a fourth attachment style that Ainsworth had not classified, and developing the method for assessing adult attachment.
Disorganized attachment (1986): working with recordings of Ainsworth's 'strange situation' experiment, Main observed that some children showed contradictory or paradoxical responses that did not fit into the three original categories (secure, anxious-ambivalent, avoidant): they froze, showed stereotyped movements, or approached the caregiver with their head turned away. She identified this fourth style—disorganized attachment (D)—highly correlated with childhood experiences of severe trauma or frightening caregivers.
Adult Attachment Interview (AAI): together with Carol George and Nancy Kaplan, she developed this semi-structured interview protocol (1985) that allows for empirically assessing adult attachment style based on how a person narrates their childhood history. The AAI is one of the most widely used instruments in adult attachment research.
Importance for the field of trauma: Main's disorganized attachment is the most robust predictor of adult dissociative pathology, severe relational difficulties, and vulnerability to complex trauma. Her work directly connects attachment theory with trauma theory and supports the clinical importance of working with early bonding.
