Condition-specific assessments
Each conclusion applies to the population and use described. These source-based assessments do not certify the full entry or replace expert clinical review.
Personality Disorders
Population and scope: Adults with DSM-IV personality disorders in the 27-person Abbass et al. (2008) trial.
Randomized studies
ISTDP was randomized against minimal-contact delayed treatment. Symptoms and interpersonal problems improved more with ISTDP during the controlled phase. Subsequent follow-up combined participants after controls also received treatment, so diagnostic reductions at follow-up are not randomized between-group effects. The small preliminary trial does not establish results for every PD subtype or superiority over an active psychotherapy.

Depression & Mood Disorders
Population and scope: Adults with persistent major-depression symptoms despite at least six weeks of antidepressant treatment, in the 60-person secondary-care Halifax trial.
Randomized studies
Town et al. (2017) randomized 20-session ISTDP against secondary-care treatment as usual. ISTDP improved the primary six-month observer-rated depression outcome more, with benefits on self-reported depression and remission measures. The small trial and routine-care comparator limit generalization to other providers, settings and active psychotherapies. This does not validate the catalogue's archived numerical estimates.

Read the recommendation and its scope. A source may discuss an approach without recommending it.
- Depression in adults: treatment and management (NG222)
Discussed in the source
NG222 names STPP, not classical long-term psychoanalysis. The distinction in the current text is supported.
Scope: Adults with depression; empirically validated short-term protocols
- Clinical Practice Guideline for Management of PTSD and Acute Stress Disorder
Discussed in the source
VA/DoD gives psychodynamic therapy a neutral recommendation for PTSD. The category does not independently establish findings for every psychodynamic protocol.
Scope: The psychodynamic-therapy category for adult PTSD; no separate grade for this specific approach.

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 conflict + interpretation of transference and resistance + working through the repetition 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.
