Mentalization-Based Tx (MBT)
Core Mechanism
Improved mentalizing capacity (understanding mental states in self and others) reduces affective dysregulation and interpersonal chaos
Ontology
Failure of mentalization under attachment stress; inability to represent mental states leads to impulsive action
Therapeutic Voice
"What do you imagine was going on in her mind when she said that?"
View of the Person
A mind that develops the capacity to think about mental states only through being thought about by another mind
