How they work
CBT
Core mechanism: Identifying and restructuring cognitive distortions + behavioral experiments + exposure reduces maladaptive appraisals and avoidance
Ontology: Dysfunctional cognitions (automatic thoughts, core beliefs) that distort appraisal of self, world, and future
MST
Core mechanism: Intensive home-based intervention targets multiple ecological systems (family, peer, school) maintaining antisocial behavior
Ontology: Antisocial behavior maintained by factors across ecological systems — not just the individual youth

What each assumes — and misses
CBT
Philosophical roots: Epictetus, Marcus Aurelius (Stoic appraisal theory — it is not things that disturb us but our judgments); Kant (rational autonomy); Popper (falsifiability as therapeutic method); Ellis cited Stoics explicitly
Blind spots: May underemphasize attachment history, relational dynamics, and the therapeutic relationship itself as mechanism of change
Therapeutic voice: What evidence do you have for the thought that nobody cares about you?
MST
Philosophical roots: Bronfenbrenner (ecological systems theory); Haley (strategic family therapy); Minuchin (structural family therapy); pragmatism (what works in context)
Blind spots: Extremely resource-intensive; requires 24/7 therapist availability; limited outside juvenile justice populations
Therapeutic voice: Let's talk about what's working in this family, because that's where we build from.
Choosing between them
CBT (Cognitive-Behavioral) and MST (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.
