The power of the adult attachment interview in predicting subsequent psychopathology: a tribute to Mary Main.

Mary Main's conceptualization and operationalization of attachment states of mind through the Adult Attachment Interview (AAI) represent seminal contributions to the attachment field. The AAI is a semi-structured clinical interview used to assess attachment states of mind that is widely used in research and clinical settings. Unresolved state of mind regarding loss or trauma has been linked to concurrent internalizing symptoms. The current study explored the associations between unresolved classification and later depression and anxiety, above and beyond trauma history and symptoms. Participants (n = 70) were parents (98.6% female, 67.1% Black/African-American) from a follow-up of a randomized clinical trial of a parenting program for families referred to child welfare services. Parents completed the AAI, Childhood Trauma Questionnaire, and the Psychiatric Diagnostic Screening Questionnaire at timepoint 1 (T1) and the Brief Symptom Inventory approximately 12 years later, at timepoint 2 (T2). Hierarchical regressions revealed that unresolved state of mind significantly predicted depression at T2, and marginally predicted anxiety at T2, above and beyond childhood trauma, post-traumatic stress symptoms, and early internalizing symptoms. These results suggest that unresolved states of mind are clinically significant and provide unique information about later internalizing symptoms in adults with a history of trauma or loss.
