Is Psychoanalytic Psychotherapy Effective?

High-quality peer-reviewed evidence demonstrating the efficacy of psychodynamic psychotherapy — a curated review of landmark studies from 2008 to 2024.

Overview

The Evidence Is Clear

The studies below represent the highest-quality evidence from the past decade demonstrating the efficacy of psychodynamic psychotherapy across multiple mental health conditions.

The evidence consistently shows that psychodynamic therapy is not only effective, but often equivalent to or superior to other established treatments — with the additional benefit of sustained and sometimes increasing effects over time.

Landmark Commentary

The Efficacy of Psychodynamic Psychotherapy

Shedler, J.

American Psychologist · February–March 2010

Am Psychol. 2010;65(2):98–109

"…the available evidence indicates that effect sizes for psychodynamic psychotherapies are as large as those reported for other treatments that have been actively promoted as 'empirically supported' and 'evidence based.' It indicates that the (often unacknowledged) 'active ingredients' of other therapies include techniques and processes that have long been core, centrally defining features of psychodynamic treatment. Finally, the evidence indicates that the benefits of psychodynamic treatment are lasting and not just transitory, and appear to extend well beyond symptom remission. For many people, psychodynamic psychotherapy may foster inner resources and capacities that allow richer, freer, and more fulfilling lives."

Broader Perspectives

Psychotherapy Is Effective but Underutilized, Review Shows

Science Daily · August 9, 2012

Source: American Psychological Association — Review of 50+ peer-reviewed studies

An APA review of more than 50 peer-reviewed studies affirmed that psychotherapy is highly effective across a wide spectrum of mental health conditions, produces long-term improvements, and reduces overall need for health services. Key findings included:

  • The average effects of psychotherapy are larger than the effects produced by many medical treatments
  • Psychotherapy reduces disability, morbidity, and mortality; improves work functioning; and decreases psychiatric hospitalization
  • Psychotherapy teaches patients life skills that last beyond the course of treatment — with results that tend to last longer than psychopharmacological treatments
  • Effects are often comparable to or better than drug treatments for the same disorders, without the potential for harmful side effects
  • A combination of medication and psychotherapy is often most effective in treating depression and anxiety

"Our goal is to help consumers weigh those messages with research-based information about how psychotherapy can provide them with safe, effective and long-lasting improvements in their mental and physical health." — Melba J. T. Vazquez, PhD, past president, APA

Longer-Duration Psychotherapy Appears More Beneficial for Treatment of Complex Mental Disorders

Science Daily · October 6, 2008

Based on: Leichsenring & Rabung meta-analysis, JAMA, October 1, 2008

Reporting on the landmark Leichsenring & Rabung JAMA meta-analysis, this summary described how long-term psychodynamic psychotherapy (at least one year or 50 sessions) proved effective and superior to shorter-term therapy for patients with complex mental disorders — including personality disorders, chronic mental disorders, and multiple comorbidities.

  • 23 studies (1,053 patients): LTPP was significantly superior to shorter methods for overall outcome, target problems, and personality functioning
  • Large and stable effect sizes for personality disorders, multiple mental disorders, and chronic mental disorders
  • Effect sizes for overall outcome increased significantly between end of therapy and follow-up

JAMA Editorial (Richard M. Glass, MD, University of Chicago): "…the meta-analysis by Leichsenring and Rabung provides evidence about the effectiveness of long-term dynamic psychotherapy for patients with complex mental disorders who often do not respond adequately to short-term interventions. It is ironic and disturbing that this occurs at a time when provision of psychotherapy by psychiatrists in the United States is declining significantly…this trend appears to be strongly related to financial incentives and other pressures to minimize costs. Is that what is really wanted for patients with disabling disorders that could respond to more intensive treatment?"
