Mentalisation-based treatment — structured clinical viva

Markers want a structured professional answer: definition of mentalising, P-P-T modes, arousal-collapse map, dual format + not-knowing stance, named trials (1999 partial hospital; 2009 MBT vs SCM), MBT vs DBT mechanism contrast, and honest stepped care when fidelity is incomplete.[2][3][6]

The capacity to understand behaviour of self and others as underpinned by intentional mental states (thoughts, feelings, wishes, desires) — implicit/explicit, self/other, cognitive/affective — fragile under high attachment arousal.[3][4]

Psychic equivalence (feeling = fact); pretend mode (empty intellectual talk disconnected from affect); teleological mode (only actions prove care/intent). Give one bedside example of each.[3][4]

Interpersonal threat/abandonment cues raise arousal → mentalising collapses → pre-mentalising organisations drive self-harm, rage, frantic contact. Secure attachment historically scaffolds mentalising capacity; adversity undermines it under stress.[3][4]

Weekly individual + weekly group (classic research duration often ~18 months). Stance: not-knowing curiosity. Techniques: stop-and-rewind, affect focus, careful challenge, mark the relationship; team mentalising to reduce splitting.[2][3]

Bateman and Fonagy 1999 partial hospitalisation RCT; follow-ups; 2009 outpatient MBT vs structured clinical management; Rossouw and Fonagy 2012 MBT-A for adolescent self-harm; meta-analyses supporting specialised BPD psychotherapies overall.[1][2][5][7]

MBT: mentalising under attachment arousal; not-knowing; dual individual-group mentalising focus. DBT: emotion dysregulation; four modes/modules; chain analysis; dialectic of acceptance and change. Both specialised options; choice depends on fit, access, and presentation — not brand exceptionalism alone.[2][6]

Risk assessment and safety plan; structured scheduled care (SCM/GPM-style); treat comorbidities; honest waitlist; avoid false fidelity claims; monitor self-harm and engagement; hope without nihilism. Structure itself is therapeutic in the generalist evidence tradition.[2][7]
