Mentalization-based treatment
psychotherapy, with aspects of psychodynamic, cognitive-behavioral, systemic and ecological approaches
Mentalization-based treatment or Mentalization-based therapy (MBT) is an integrative form of psychotherapy, bringing together aspects of psychodynamic, cognitive-behavioral, systemic and ecological approaches. MBT was developed and manualised by Peter Fonagy and Anthony Bateman, designed for individuals with borderline personality disorder (BPD). Some of these individuals suffer from disorganized attachment and failed to develop a robust mentalization capacity. Fonagy and Bateman define mentalization as the process by which we implicitly and explicitly interpret the actions of oneself and others as meaningful on the basis of intentional mental states. An alternative and simpler definition is "Seeing others from the inside and ourselves from the outside." The object of treatment is that patients with BPD increase their mentalization capacity, which should improve affect regulation, thereby reducing suicidality and self-harm, as well as strengthening interpersonal relationships. A version of MBT has also been developed for individuals with antisocial personality disorder (MBT-ASPD), delivered primarily in a group setting. Because individuals with ASPD are more likely to engage and learn from peers they perceive as similar, the focus of MBT-ASPD is on facilitating constructive group interactions that support mentalizing and behavioral change.
More recently, a range of mentalization-based treatments, using the "mentalizing stance" defined in MBT but directed at children (MBT-C), families (MBT-F) and adolescents (MBT-A), and for chaotic multi-problem youth, AMBIT (adaptive mentalization-based integrative treatment) has been under development by groups mainly gravitating around the Anna Freud National Centre for Children and Families. Moreover, the MBT model has been used in treating patients with eating disorders (MBT-ED)
The treatment should be distinguished from and has no connection with mindfulness-based stress reduction (MBSR) therapy developed by Jon Kabat-Zinn.
Goals
The major goals of MBT are:
better behavioral control
increased affect regulation
more intimate and gratifying relationships
the ability to pursue life goals
This is believed to be accomplished through increasing the patient's capacity for mentalization in order to stabilize the client's sense of self and to enhance stability in emotions and relationships.
Begin with the source’s own compact description: “Mentalization-based treatment” is psychotherapy, with aspects of psychodynamic, cognitive-behavioral, systemic and ecological approaches. The dossier treats that line as a proposition to test through Mentalization-based, treatment and psychotherapy, not as a finished interpretation.
Why this record matters
The phrase “psychotherapy, with aspects of psychodynamic, cognitive-behavioral, systemic and ecological approaches” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jul 16, 2025. The linked authority identifier is Q6817506. The Library of Congress control number is sh2017000495. None of the 1 selected statements returned an explicit reference.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
