How they work
ISTDP
Core mechanism: Rapid defense restructuring + breakthrough to warded-off affect dissolves symptom-generating patterns
Ontology: Unconscious anxiety about forbidden feelings toward attachment figures; defenses create symptoms
Psychoanalysis
Core mechanism: Insight into unconscious conflicts + transference interpretation + corrective emotional experience reorganizes relational patterns
Ontology: Unconscious conflict between drives, defenses, and internalized relationships

What each assumes — and misses
ISTDP
Philosophical roots: Freud (repression); Reich (character armor — defenses held in the body); Davanloo (unlocking the unconscious through pressure)
Blind spots: High confrontation can destabilize fragile clients; may underestimate the protective function of defenses in complex trauma
Therapeutic voice: You say you feel nothing — but I can see your hands are clenched. What are you experiencing right now?
Psychoanalysis
Philosophical roots: Freud; Nietzsche (drives beneath reason); Schopenhauer (will as unconscious force); Ricoeur (hermeneutics of suspicion); Klein, Bion, Winnicott (object relations)
Blind spots: May neglect behavioral activation and symptom stabilization while pursuing insight; long timeframes can delay relief
Therapeutic voice: What comes to mind when you notice that feeling?
Choosing between them
ISTDP and Psychoanalysis both sit within the Psychoanalytic 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.
