ISTDP
Core Mechanism
Rapid defense restructuring + breakthrough to warded-off affect dissolves symptom-generating patterns

Unconscious anxiety about forbidden feelings toward attachment figures; defenses create symptoms

"You say you feel nothing — but I can see your hands are clenched. What are you experiencing right now?"
View of the Person
An affective being whose defenses against feeling generate symptoms
