The links between unresolved maternal attachment status, disrupted maternal interaction in play situations, 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 Instrument 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.
