Unresolved/Unclassifiable responses to the Adult Attachment Interview: Predictable from Unresolved States and Anomalous Beliefs in the Berkeley-Leiden Adult Attachment Questionnaire

Unresolved/disorganized (U/d) states of mind are identified in the Adult Attachment Interview through lapses in the monitoring of reasoning or discourse during the discussion of traumatic events (LapseTr), and have been found to predict infant Disorganized/ disoriented responses to the parent in the Ainsworth Strange Situation.The Berkeley-Leiden Adult Attachment Questionnaire (BLAAQ-U)-a 58-item inventory intended to identify U/d subjects--is composed of two major scales: Unresolved States of Mind (USM, e.g., feelings of responsibility for a-death) and Unusual Beliefs (B, e.g., mental telepathy).Inventory construction took place across successive applications to one Dutch and two Berkeley Student samples.Scales were reliable, and stable across both 3 weeks and 12 months.USM and B scales were each correlated with LapseTr.Unclassifiable subjects resembled U/d subjects: Both discriminant analyses and cut-off scores discriminated the Unresolved/Unclassifiable subjects.
