Unresolved states of mind, disorganized attachment relationships, and disrupted mother– infant interactions of adolescent mothers and their infants

The links between unresolved maternal attachment status, disrupted maternal interaction in play situa-tions, and disorganized attachment relationships were examined in a study of 82 adolescent mother– infant dyads. Maternal interactive behavior was measured using the Atypical Maternal Behavior Instru-ment for Assessment and Classification coding system. Additional rating scales were developed to correspond to the 5 dimensions of disrupted maternal behavior outlined by E. Bronfman, E. Parsons, and K. Lyons-Ruth (1999). A robust association was observed between disrupted maternal behavior and disorganized attachment. Ratings of disrupted maternal behavior revealed that disorganized attachment relationships were strongly related to ratings of fearful/disoriented behavior. Moreover, mothers who were unresolved were more likely than not-unresolved mothers to show disrupted patterns of interaction with their infants. Regression analyses suggested that disrupted behavior statistically mediated the association between unresolved status and disorganized attachment relationships
