It is well documented how adverse childhood experiences can inhibit child development and mentalizing ability and lead to high risk of developmental psychopathology. Mentalization-based treatment (MBT) has been established as an effective approach to treatment for a long range of psychopathologies with both in- and outpatient treatment, yet the evidence base for effective clinical interventions that can help guide professionals working in residential care on how to support the development of neglected and traumatized children is underdeveloped. This article demonstrates a mentalization-based approach to understanding and working with children in residential care, and offers practical models and tools as well as considerations on implementation that are beneficial and easy to apply, demonstrated through cases. The STORM model and “Obtaining Skills” screening tool may be helpful models for professionals addressing mentalization in children while working in challenging environments such as with traumatized and neglected children.
