Outcome Research in Adults - Update 2

In the following section,

(1) evidence for the efficacy of psychodynamic therapy in specific mental disorders in adults will be briefly summarized by listing relevant publications.

(2) In addition, open questions of research will be formulated.


1. Evidence for psychodynamic therapy in adults


Randomized controlled trials, reviews and meta-analyses

A growing number of randomized controlled trials (RCTs), reviews and meta-analyses for psychodynamic therapy (PDT) in specific mental disorders is available showing that psychodynamic therapy is efficacious and as efficacious as other empirically supported treatments, demonstrated, for example, by


- Peter Lilliengren´s list of RCTs (https://www.kbap.de/fileadmin/users/redakteur/redakteur_upload/Liliengrenliste.pdf)

- reviews on PDT (Fonagy, 2015; Leichsenring et al., 2023; Leichsenring, Leweke, et al., 2015; Leichsenring, Luyten, et al., 2015; Shedler, 2010)

- Meta-analyses of psychodynamic therapy in specific mental disorders or groups providing evidence for efficacy in 

  • depressive disorders (Barber et al., 2021; Driessen et al., 2020; Driessen et al., 2015; Leichsenring et al., 2023)

  • anxiety disorders  (Barber et al., 2021; Keefe et al., 2014; Leichsenring et al., 2023; Noren et al., 2026)

  • personality disorders (Barber et al., 2021; Fonagy et al., 2025; Keefe et al., 2020; Leichsenring et al., 2023)

  • somatoform disorders (Abbass et al., 2021; Gutkin et al., 2020; Leichsenring et al., 2023)

  • complex mental disorders (Leichsenring et al., 2013; Leichsenring & Rabung, 2008, 2011)

  • transdiagnostic evaluations (Leichsenring et al., 2004; Steinert, Munder, et al., 2017)

- Comparison of psychodynamic therapy with other empirically supported treatments (Barber et al., 2021; Driessen et al., 2015; Keefe et al., 2014; Keefe et al., 2020; Leichsenring et al., 2023; Leichsenring et al., in press; Miggiels et al., 2026; Steinert, Munder, et al., 2017) showing no clinically significant differences in efficacy.

- RCTs, reviews and meta-analyses for long-term psychodynamic therapy (Clarkin et al., 2007; Doering et al., 2010; Fonagy et al., 2015; Heim et al., in press; Leichsenring et al., 2013; Leichsenring & Rabung, 2008, 2011; Leuzinger-Bohleber et al., 2019; Moser et al., 2026)

- Studies and meta-analyses of combined PDT and pharmacotherapy in

  • depressive disorders (de Jonghe et al., 2004; de Jonghe et al., 2001; Driessen et al., 2020)

  • anxiety disorders(Wiborg & Dahl, 1996)

  • OCD (Maina et al., 2010)

  • schizophrenic spectrum disorders (Montag et al., 2014; Øhlenschlæger et al., 2007; Weijers et al., 2021)

Additional gain of psychodynamic therapy compared to other evidence-based therapies

PDT has been shown to achieve additional gains compared to other evidence-based therapies with regard to

  • attachment, reflective functioning (Levy et al., 2006)

Research on Internet-guided psychodynamic therapy

There is evidence that internet-guided PDT (Lindegaard, Berg, et al., 2020) is efficacious in

  • depressive disorders (Johansson et al., 2012; Lindqvist et al., 2026)

  • anxiety disorders (Andersson et al., 2012; Johansson et al., 2017; Lindegaard, Hesslow, et al., 2020; Mechler et al., 2024)

Effectiveness studies

There is evidence that PDT is effective under real-world conditions (e.g. Henkel et al., 2025; Stiles et al., 2008).


Research on Cost-effectiveness

There is evidence that PDT is cost-effective. (Abbass, 2003; Bothe et al., 2023; Dams et al., 2017; Dührssen, 1962; Egger et al., 2016; Konnopka et al., 2009; Lilliengren et al., 2020; Shefler et al., 2024; Town et al., 2020)


Efficacy of PDT in minority groups

There is first evidence that PDT is efficacious in

  • LGPTQ (Keefe et al., 2023)

  • minority groups (Barber et al., 2012)

2. Outcome research in adults: open questions and future research of psychodynamic therapy in adults


Informing about open questions and giving hints for future directions of research may be even more important than informing about the available evidence for PDT. Formulating open questions of research may direct and promote psychodynamic research and may especially be helpful for young researchers, e.g. for grant applications. In the following, areas and questions of outcome research are listed for which further research is required.


Evidence on dose effect relationships is required

It has not yet been clarified how many sessions of which treatment in which conditions work for whom. A recent RCT by Kool et al. (2024) showed that both 50 sessions (twice weekly) of PDT and schema therapy are more efficacious than 25 sessions in adults with depression and comorbid personality disorders. However, it is not clear whether the majority of patients benefitted sufficiently from 50 sessions and which patients may need more than 50 sessions to achieve a substantial improvement. This applies to other mental disorders as well.


Long-term psychodynamic therapy

At present, only relatively few RCTs and meta-analyses on long-term PDT (LTPP) are available (Clarkin et al., 2007; Doering et al., 2010; Fonagy et al., 2015; Leichsenring et al., 2013; Leichsenring & Rabung, 2008, 2011; Moser et al., 2026). This is especially true for psychoanalytic therapy (Huber et al., 2013; Huber et al., 2012; Leuzinger-Bohleber et al., 2019).

Thus, further evidence on long-term treatments is required.


Long-term outcome 


Further RCTs and meta-analyses on long-term outcome of PDT are required.

  • The meta-analyses providing evidence for PDT in depressive, anxiety, and personality disorders according to the 2015 criteria of the APA (Tolin et al., 2015) showed that PDT did not differ from active therapies in follow-ups with regard to reducing target symptoms. However, this does not necessarily imply that effects are stable. In the worst case, active therapies were not efficacious in follow-ups as well, implying that both PDT and active therapies did not yield stable effects.

  • As the only exception, meta-analytic results of PDT in somatoform disorders showed that PDT was superior to controls in follow-ups (Abbass et al., 2021; Leichsenring et al., 2023).

  • For depression, the meta-analysis by Driessen et al. (2015) showed that the treatment effects of PDT were maintained or significantly showed further improvement between end of therapy and follow-up.

  • For these reasons, further RCTs and meta-analyses are required showing that PDT is superior to controls in follow-ups, especially in anxiety and personality disorders (Bateman & Fonagy, 2009; Keefe et al., 2020).

Psychosocial Functioning


Further RCTs and meta-analyses of PDT on functioning especially in anxiety disorders are required.

  • The meta-analyses providing evidence for PDT in anxiety disorders according to the 2015 criteria of the APA (Tolin et al., 2015) showed that PDT did not differ from active therapies with regard to improving functioning (Barber et al., 2021; Keefe et al., 2014; Leichsenring et al., 2023). Again, in the worst case, active therapies were not efficacious in improving functioning, too, implying that both PDT and active therapies were both not efficacious in improving functioning.

  • For this reason, further RCTs and meta-analyses are required showing that PDT is superior to controls in improving functioning in anxiety disorders.

American Psychological Association 2015 criteria for empirically supported psychotherapies


PDT fulfills the 2015 criteria of the American Psychological Association (Tolin et al., 2015) for empirically supported therapies for depressive, anxiety, personality and somatoform disorders (Leichsenring et al., 2023).


For other mental disorders, however, some RCTs exist but the number of RCTs is limited and meta-analyses which are required by the criteria proposed by Tolin et al. (2015)  are not yet available. This applies to the following disorders for which further RCTs and meta-analyses are required to fulfil the 2015 APA criteria (Tolin et al., 2015):


  • Cluster C personality disorders (Muran et al., 2005; Svartberg et al., 2004; Winston, 1994)

  • eating disorders

- bulimia nervosa (Garner et al., 1993; Poulsen & Lunn, 2014; Poulsen et al., 2014; Stefini et al., 2017; Tasca et al., 2014)

- binge eating (Tasca et al., 2012)

- anorexia nervosa (Dare, 2001; Gowers et al., 1994; Lock et al., 2010; Zipfel et al., 2013)

  • addictions

- opiate (Woody et al., 1985; Woody et al., 1983; Woody et al., 1990)

- cocaine (Crits-Christoph et al., 1999; Crits-Christoph et al., 2001)

- alcohol (Sandahl et al., 1998)

  • PTSD (Brom et al., 1989; Leichsenring et al., in press; Steinert, Bumke, et al., 2017; Steinert, Bumke, et al., 2016), with ongoing studies by Barbara Milrod et al.

Further RCTs

Independent of but related to the APA criteria further RCTs of psychodynamic therapy in specific disorders are required. This applies to:

  • schizophrenic spectrum disorder

  • bipolar disorders

  • PTSD

  • non-substance related addictions for example, gambling, shopping, sex, pornography.

  • further high quality evidence for PDT in specific anxiety disorders. Several studies were shown to be of low study quality (Leichsenring et al., 2023). For generalized anxiety disorder, for example, only a few RCTs of PDT exist (Papola et al., 2023).

  • adjustment disorders

  • sexual dysfunctions

  • for OCD, one recent study showed that PDT is efficacious in OCD (Leichsenring et al., 2026), but further studies are required to confirm the results.

Specific outcomes

Future studies of PDT focusing on specific outcomes are required, such as:

  • functioning (Leichsenring et al., 2023)

  • attachment

  • reflective functioning

  • cost-effectiveness

Additional gain of PDT

Future studies are required focusing on outcomes which may specific to PDT, e.g.:

  • conflicts

  • attachment

  • reflective functioning

  • defense mechanisms

Transdiagnostic approaches, unified protocols

Unified transdiagnostic psychodynamic protocols are available for several disorders, but further studies testing their efficacy are required, this applies to

  • emotional disorders (Leichsenring & Steinert, 2018)

  • depressive disorders(Leichsenring & Schauenburg, 2014; Meganck et al., 2023; Steinert, Schauenburg, et al., 2016)

  • anxiety disorders (Busch et al., 2012; Leichsenring & Salzer, 2014)

  • personality disorders (Caligor et al., 2018)

  • transdiagnostic features (e.g. perfectionism Hewitt et al., 2023; Hewitt et al., 2020)

Cost-effectiveness studies

Further studies of cost-effectiveness of psychodynamic therapy in specific disorders required.
