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
FFT
Core mechanism: Reframing family interactions + improving communication + building problem-solving disrupts cycles maintaining youth antisocial behavior
Ontology: Youth behavioral problems maintained by family interaction patterns and lack of protective relational processes

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.
FFT
Philosophical roots: Bronfenbrenner (ecological systems); Alexander (functional family therapy model); Haley/Minuchin (structural-strategic); social learning theory
Blind spots: Requires family engagement — ineffective when family is unavailable or actively harmful; juvenile-justice focused
Therapeutic voice: Let's practice having this conversation differently. Instead of blaming, can you start with how you feel?
Choosing between them
FBT / Maudsley and FFT 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.
