New Zealand psychologists, discover how early attachment disruptions impact mentalising and personality development in Dr. Ella Brent's concluding talk. Gain a deeper understanding of maladaptive personality formation and learn to apply Mentalization-Based Treatment principles alongside DBT for effective clinical intervention.
In the concluding talk of this three-part series, clinical psychologist Dr. Ella Brent examines how disruptions in early attachment relationships can hinder the development of key psychological capacities, including affect regulation, attention control, and mentalising. Building on foundational material presented in Parts 1 and 2, this session focuses on the consequences of insecure attachment in the caregiver-child dyad and how these relational patterns may impair mentalising development.
Through illustrative case examples, Dr. Brent explores how inconsistent, misattuned, or invalidating caregiving may result in maladaptive personality development. The talk outlines the continuum from early relational disruptions to the emergence of personality vulnerabilities and disorders, drawing connections between impaired mentalising and common personality organisation clusters, including borderline, dependent, histrionic, narcissistic, schizoid, and antisocial presentations.
This talk further differentiates Mentalization-Based Treatment (MBT), developed by Anthony Bateman and Peter Fonagy, from but aligned with Dialectical Behaviour Therapy (DBT), developed by Marsha Linehan. Clinicians will gain practical and theoretical tools to recognise, assess, and respond to clients with impaired mentalisation capacities in both adult and adolescent populations.
