How they work
CBT-E
Core mechanism: Disrupting the transdiagnostic maintaining mechanisms (over-evaluation of shape/weight, dietary restraint, low self-esteem, perfectionism, interpersonal difficulty)
Ontology: Eating disorders maintained by a shared cognitive-behavioral maintaining system, not distinct etiologies per diagnosis
FBT / Maudsley
Core mechanism: Empowered parents take charge of refeeding; externalization separates illness from identity; control gradually returns to adolescent
Ontology: Anorexia as an illness requiring parental intervention (agnostic about cause); adolescent cannot recover alone

What each assumes — and misses
CBT-E
Philosophical roots: Fairburn (transdiagnostic maintaining mechanisms); Beck (cognitive model); pragmatism (target what maintains, not what caused)
Blind spots: Transdiagnostic focus may miss disorder-specific nuance; requires client motivation which is often compromised in anorexia
Therapeutic voice: I notice you weighed yourself four times today. Let's look at what was happening emotionally before each time.
FBT / Maudsley
Philosophical roots: Pragmatism (agnostic about etiology — just refeed); family systems (externalization); medical model (anorexia as illness requiring parental intervention); anti-blame stance
Blind spots: Requires highly involved parents; etiology-agnostic stance can frustrate families seeking understanding; narrow to eating disorders
Therapeutic voice: Your job right now is to make sure your daughter eats. This isn't about blame — it's about her survival.
Choosing between them
CBT-E (Cognitive-Behavioral) and FBT / Maudsley (Family Systems) come from different traditions, which means they assume different things about what a person is, what causes suffering, and what the therapeutic relationship is for. The choice between them is often less about "which works better" and more about which set of assumptions fits the client and the therapist.
