This study explored the psychometric properties of the Adult Attachment Behaviours Inventory for Intellectual Disabilities (AABI‐ID). We also examined the association between attachment behaviours and adaptive and behavioural profiles and reflected on the clinical use of the AABI‐ID.\n\n\nMethods\nThe AABI‐ID aims to assess the presence and selectivity of attachment‐related behaviours in adults with intellectual disabilities towards care professionals. In this study, it was completed for 152 adults. Individual support workers (ISWs) and other support workers (OSWs) provided ratings alongside assessments of adaptive and challenging behaviours.\n\n\nResults\nResults indicated excellent internal consistency and good test−retest reliability. Differential profiles were observed in ISWs and OSWs. Furthermore, significant positive associations were identified with the Vineland Adaptive Behaviour Scales, Second Edition and Behavior Problems Inventory.\n\n\nConclusions\nThe AABI‐ID appears to be a promising tool for fostering professional reflexivity and enhancing the integration of attachment behaviours in daily clinical practice.\n"]
