Gestalt Therapy

Founders and the mid-twentieth-century setting

A 2023 mixed-methods study published in Frontiers in Psychology describes Gestalt therapy as a form of psychotherapy developed by Fritz and Laura Perls, Ralph Hefferline and Paul Goodman in the 1940s and 1950s. The same account says it is rooted in existential philosophy, influenced by Gestalt psychology, and concerned with the holistic perception of experience. A foundational text by these authors, cited in the later literature as Perls and colleagues, is the source of several definitions that current researchers quote.

The sources reviewed for this page do not give the publication dates of that foundational text or an account of the individual founders' biographies. Those details need a dedicated historical source before they are added.

Humanistic lineage

Researchers writing from within the field place the approach in the humanistic psychotherapy tradition, which treats a person as an integrated whole whose physical, mental and emotional parts are tied to a social and environmental context. A 2025 French cohort study calls it a humanistic, experiential, integrative and embodied approach and emphasizes its relational focus on the person and their environment as a single field. These are descriptions by Gestalt therapists and researchers, and they state the approach's own framework, not an independent classification.

Professional organization in Europe and the United Kingdom

A page hosted by an Italian Gestalt institute states that 13 representatives of Gestalt associations and institutes from 11 European countries met in Germany on 5 May 1985 to found the European Association for Gestalt Therapy (EAGT). The page is undated and unsigned. A UK training provider, the Gestalt Centre London, states that it was established in 1980 to provide psychotherapy training and lists UKCP registration routes for its graduates. Both statements are institutional self-descriptions.

In Austria, the authors of the 2023 study report that Integrative Gestalt therapy is a recognized psychotherapy approach for the treatment of mental illness. The sources reviewed do not describe how recognition works in other countries, and requirements differ by jurisdiction.

Gestalt therapy and Gestalt psychology

Gestalt therapy is a psychotherapy. It is not the same thing as Gestalt psychology, the earlier school of perception research that the 2023 study says influenced it. One idea carried over is the figure-ground distinction, which describes how a person organizes perception by separating what is in the foreground of attention from what stays in the background. Similar words do not make the two fields equivalent, and findings in one do not transfer to the other.

Vocabulary used by practitioners

Practitioners describe the self as a system of contacts that forms at the boundary between a person and their environment, moment by moment. Other terms in the 2025 French cohort study include awareness, creative adjustment, and four ways in which practitioners say awareness can be blocked: introjection, projection, retroflection and confluence. The term unfinished business refers to unresolved emotional matters that practitioners see as needing closure. These are concepts of the tradition and are not measured biomedical constructs.

Variants and derived names

The label Integrative Gestalt therapy is used in Austria for a version that adds developmental and psychodynamic perspectives. Dialogical exposure therapy is a separate, Gestalt-derived trauma method that two research papers describe, one as an integrative gestalt-derived intervention and the other as using the Gestalt empty-chair method. Results for such derived methods describe those methods, and should not be read as results for Gestalt therapy in general.

How sessions are described

The authors of the 2023 study write that a Gestalt session is not rigidly structured. Instead, it follows the client's unfolding experience, with some recurring elements: building the therapeutic relationship, a focus on the present, and attention to emotions, thoughts and behavior. Therapists may suggest experiments and exercises, work with resistance, give feedback and shared observations, and close the session with reflection. Homework between sessions is sometimes suggested.

A 2025 French study adds that Gestalt therapists describe their stance as one of presence, awareness and responsibility, and that they invite clients to notice current thoughts, emotions and movements instead of concentrating on past or anticipated events. This is a practitioner description of the intended attitude and does not show what occurs in any particular session.

Techniques named in the literature

The empty chair technique lets a client speak to an imagined person or to a part of themselves. Other techniques named in the same account include re-enacting dreams, role-play used to address inner conflicts, exercises to build body awareness, imagination and visualization. Which techniques are used, and how often, varies by therapist and by client, and this page does not give instructions for them.

Length and format in published studies

In the French cohort study, the program offered was 33 one-hour sessions, with a minimum of 12, spread over several months with a maximum of two years. Participants averaged about 31 sessions over roughly 13 months. A trial in Iran used eight weekly counseling sessions of 45 minutes, and a Bosnian trial used seven group sessions. These are research protocols, and everyday practice may differ.

Reasons people seek it

In the French cohort study, the authors write that the client lists of Gestalt psychotherapists are mainly made up of people with mild-to-moderate anxiety and depressive disorders, often with problems of self-esteem, loss, grief and separation. They grouped clients by presenting complaint and not by formal diagnosis. This reflects one network of French practitioners and may not describe clients elsewhere.

Aims stated by practitioners and researchers

Practitioners describe the aims as greater self-awareness, acceptance, personal responsibility, authenticity and growth. The 2023 study adds that working through unfinished business is described as giving a sense of closure, and that the approach aims to strengthen a client's sense of empowerment and agency. These are stated goals of the approach and are not outcomes shown by the studies cited here.

Applications that have been studied

Published studies have applied Gestalt therapy or Gestalt-derived methods to post-traumatic stress, traumatic bereavement, self-esteem and intimate partner violence in pregnancy, chronic whiplash symptoms combined with body therapies, and depression in people with dementia. For the last, the report found is a research protocol, whose authors describe the efficacy of Gestalt therapy as under-investigated. A study of one population cannot be applied to another.

Reviews and the state of the field

A German-language meta-analysis in 1994 pooled 38 evaluation studies conducted between 1970 and 1986. Its authors concluded that Gestalt therapy was an effective psychotherapeutic treatment not inferior to comparable methods, but said no definitive statement could be made about differential indication, individual therapy setting or long-term effects. Only the abstract could be read for this page, and the pooled studies are now at least four decades old.

A PubMed search run for this page, combining Gestalt therapy in the title or abstract with systematic review, meta-analysis or randomized terms, returned nine records and no recent systematic review specific to the approach. Researchers writing in 2022 and 2025 describe the evidence as under-investigated, scarce and largely qualitative. Other databases were not searched, and clinical guidelines were not reviewed for this draft.

Trials of Gestalt-derived trauma methods

A randomized trial of 141 adults with post-traumatic stress disorder compared dialogical exposure therapy, a Gestalt-derived method, with cognitive processing therapy, an established cognitive-behavioral treatment, for up to 24 sessions. Dropout was 12.2 percent and 14.9 percent. Both groups improved substantially on the Impact of Event Scale-Revised and the gains were largely stable at six months, but after treatment the cognitive method performed better on symptom and cognition measures. The authors concluded that the Gestalt-derived method merits further research.

A quasi-randomized trial of 119 women in Bosnia and Herzegovina who had lost husbands in the war compared seven group sessions using the Gestalt empty-chair method with a supportive group. Both improved, with a moderate effect size (Cohen d 0.56) in the empty-chair group against a small one (0.34) in the supportive group. The empty-chair group did better on traumatic grief and avoidance, and the authors noted little additional effect overall.

Other trials and uncontrolled studies

A trial of 60 pregnant women in Iran compared eight weekly Gestalt-based counseling sessions with a wait-list. It was unblinded, and the abstract reports that the intervention group scored higher on self-esteem afterward (74.47 compared with 66.28 on the Rosenberg scale) and lower on a violence questionnaire. A Danish randomized trial of 87 people with chronic whiplash tested Gestalt psychotherapy combined with two body therapies and found no clinically relevant effect at about three months, so it cannot be attributed to Gestalt therapy alone.

The largest recent study, of 319 French adults with mood or anxiety disorders, had no control group. Anxiety and depression scores on the Hospital Anxiety and Depression Scale fell between the first and last session, with a mean anxiety score of 10.87 before and 7.58 after. The authors note that the study lasted a year, that self-reports can be biased by social desirability, and that 23 percent of cases were not completed. A change without a comparison group cannot be attributed to the therapy.

Harms reported

A 1977 study in Archives of General Psychiatry followed 33 people in long-term individual therapy who were referred to weekend groups, two of them affect-arousing Gestalt groups. At six weeks the Gestalt groups showed some greater improvement in individual therapy, with no differences by twelve weeks. The authors reported that the weekend was not without risk, because two patients suffered considerable psychological damage even though the group leaders were highly trained, and intense affect was not linked to positive change. The study is small, old and concerns a group weekend format, so it cannot be applied directly to individual sessions today.

A 2019 systematic review of instruments for measuring negative effects of psychotherapy found that this area is comparatively rarely researched, and that the instruments identified covered 17 domains without consensus. Most of the Gestalt studies cited on this page do not describe how unwanted effects were tracked in the abstracts reviewed, so the frequency of negative effects in Gestalt therapy is not established.

Suitability and care boundaries

The French cohort study excluded people with psychotic disorders, substance addiction, cognitive deficits suggesting a neurocognitive disorder, suicidal intent or guardianship, so its results do not apply to them. The authors of a 2023 case series of seven clients report no change in the level of personality functioning after 30 sessions, and limited positive emotional experience in the low-integrated group. Sessions involve emotion and body-focused exercises, so a person can ask a therapist what an exercise involves and can ask to pause or stop.

This page is educational and does not replace assessment or treatment. Persistent or worsening distress, thoughts of self-harm, or symptoms that could have a medical cause call for assessment by a qualified clinician, and an emergency calls for emergency services.

Training and registration

The EAGT page says the association adopted minimum training criteria and a code of ethics, and that it confirms the award of the European Certificate of Gestalt Psychotherapist as the awarding organization within the European Association for Psychotherapy. In the French cohort study, participating therapists had trained at institutes accredited by these bodies and held the European Certificate. In the United Kingdom, the Gestalt Centre London states that its Psychotherapy Practitioner Diploma leads to UKCP registration as a Gestalt Psychotherapist or Gestalt Group Psychotherapist, under the UKCP's Humanistic and Integrative Psychotherapy College.

These are the bodies' and a training provider's own statements, and not an independent audit. Requirements and titles differ by country, and this page did not check which national titles are protected.
