How they work
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
Structural Family Therapy
Core mechanism: Joining the family system, then actively restructuring dysfunctional boundaries and hierarchies through enactment, unbalancing, and boundary-making → reorganized family structure supports healthier functioning
Ontology: Symptomatic behavior is maintained by dysfunctional family structure — unclear boundaries, inappropriate hierarchies, and rigid or diffuse subsystem organization

What each assumes — and misses
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.
Structural Family Therapy
Philosophical roots: Systems theory (Bertalanffy); cybernetics; Bateson (ecology of mind); Minuchin's own experience with immigrant families in New York; structural anthropology (Lévi-Strauss — deep structures organizing surface behavior)
Blind spots: Therapist-as-expert model can be culturally inappropriate; hierarchical assumptions may not fit all family forms; less attention to individual intrapsychic processes; limited as standalone evidence base
Therapeutic voice: Instead of telling me about the argument, have the argument here. Show me what happens.
Choosing between them
FBT / Maudsley and Structural Family Therapy both sit within the Family Systems tradition — they share a worldview about what suffering is and how change happens. Differences are more often about technique and emphasis than about underlying theory.
