Jungian analytical psychology

Jung and the Zurich beginnings

Carl Gustav Jung (1875–1961) was a Swiss psychiatrist whose work gave rise to the school now called analytical psychology. An encyclopedia entry by Murray Stein describes the school as the theory and clinical practice Jung developed after separating from Freud, and notes that the institute in Zurich continued his work after his death in 1961. A 2018 conference of the International Association for Analytical Psychology and the University of Basel was held, in the words of its organizer, at the place where Jung began his academic career.

The break with Freud

The same encyclopedia gathers two accounts of the split with Sigmund Freud that differ on timing. One entry says Jung, who had been first president of the international psychoanalytic body in 1910, resigned in 1914 after two years of uncertain allegiance. The other says the break came at the end of 1912. Both place the disagreement in Jung's view of libido as a single psychic energy flowing between conscious and unconscious rather than as sexual instinct, and both treat his 1913 book Psychology of the Unconscious as making the separation unavoidable.

Institutes and the international association

According to the encyclopedia entry, the Society of Analytical Psychology in London began the first training program in 1945, the C. G. Jung Institute in Zurich opened in 1948, and the International Association for Analytical Psychology (IAAP) was founded in 1955. It reports 23 training institutes worldwide by 1996 and roughly 2,000 professional analysts by 1997. The IAAP's current member-societies page lists about 81 group members by region and gives no analyst total. The figures use different dates and counting rules, so they are not a growth rate.

Names for the school

Analytical psychology is the name Jung's approach carries in the encyclopedia entries, set apart from Freud's psychoanalysis. In clinical research the treatment itself is usually called Jungian psychotherapy or Jungian analysis, and practitioners are called Jungian analysts. Depth psychology appears as a wider label in some journal abstracts, which place Jung's ideas on individuation, shadow work and cultural complexes inside it. Jungian analytical psychology is therefore the tradition, while analysis and psychotherapy are the clinical forms it takes.

Core concepts in the school's own terms

The encyclopedia entry defines the collective unconscious as an inherited base beneath the personal unconscious, also called the objective psyche, and archetypes as inherited patterns of psychic functioning that show up in images such as the hero or the mandala. Individuation is described as a lifelong movement from the ego and persona toward a total self that joins conscious and unconscious. The shadow is the set of aspects of the psyche denied in conscious life. These are concepts of the school, and the entry itself records criticism of them.

Complexes, feeling-toned clusters of psychic material, are a further core idea. Contributors to the Basel conference described the evidence for complexes and the psychodynamic unconscious as comparatively solid, while the archetype concept was described as controversial.

Analysis and psychotherapy

Studies of Jungian psychotherapy, carried out mainly in Germany and Switzerland, describe outpatient treatment of varying length. A Swiss prospective study followed 37 cases for a mean of 35 months and 90 sessions, a low-frequency format. A 2025 German training-institute study recorded 18 to 306 sessions, with a mean near 71, and notes that the tradition holds each therapy should be tailored to the individual process. A historical article on Jung stresses that he treated the personal histories of both clinician and patient, and the transference and countertransference between them, as shaping outcomes.

Schools within the tradition

Stein's entry distinguishes a classical or Zurich school, based on Jung and followers including Marie-Louise von Franz, Carl A. Meier and Edward Edinger, which emphasizes symbolic work with dreams. It contrasts this with a developmental or London school led by Michael Fordham, which draws on object relations theory and attends to childhood development and transference, and notes a recent generation trying to combine the two. Andrew Samuels, in a 2024 IAAP interview page, is credited with describing three schools: classical, developmental and archetypal. The sources reviewed do not describe what the archetypal school teaches.

Practices linked to this page

Machipedia pages tagged with Jungian analytical psychology include Sandplay, Dreamtime Interpretation, Divine Feminine, Divine Masculine and Mandala Therapy, and the shadow concept is the background to Shadow Work. Sources reviewed show only some of these links. The encyclopedia names the mandala as an example of an archetypal image, and authors of a Colombia and Argentina program describe Expressive Sandwork as a Jungian psychosocial intervention. Others, such as Dreamtime Interpretation, are not shown by these sources to belong to Jungian training.

Aims in the school's own terms

The tradition holds that therapy supports individuation, the lifelong integration of conscious and unconscious material, including contents the school calls the shadow. Roesler and Reefschläger describe Jungian psychotherapy as a prototype of spiritually integrated psychotherapy, in which meaningful coincidences, called synchronicity, are treated as material for the work. A historical article credits Jung with approaching psychotic symptoms as meaningful and communicative rather than only as concealment. These are statements of what the school holds, not findings.

Conditions in the outcome literature

The outcome literature concerns Jungian psychotherapy as a general treatment rather than a program for one condition. In the Swiss prospective study, 57 percent of patients had depressive disorders and 47 percent had personality disorders. The 2025 training-institute study measured depression, anxiety, obsessive-compulsive and eating disorder symptoms. These samples describe who was treated, not who the approach suits.

Naturalistic outcome studies

Roesler's 2013 review summarizes studies since the 1990s, mainly in Germany and Switzerland, using prospective and retrospective naturalistic designs and health insurance data. The review reports improvements in symptoms, interpersonal problems and personality structure that remained stable for up to six years after therapy, with fewer health care visits afterward. The Swiss prospective study had 26 therapists and no control group. A later paper describes the Berlin study as following 111 patients six years after treatment, with 86.6 percent rating well-being as good to very good.

A 2025 training-institute study

A 2025 pre-post study of 104 patients treated by trainees at a German Jungian institute found improvements in depression, anxiety and obsessive-compulsive symptoms, with effect sizes from d = 0.555 to d = 1.174, and in self-perception and relationships. Eating disorder symptoms did not change significantly (p = .275). The study had no control group, so it cannot separate the therapy from spontaneous recovery or other influences, and its authors call for randomized trials and long-term follow-up.

Limits of the evidence

The authors of the 2025 study state that no randomized controlled trials of Jungian psychotherapy exist, that internal validity of the naturalistic studies can be questioned, and that no conclusion about efficacy is currently possible, only about effectiveness in practice settings. They add that retrospective studies are affected by selection bias. A 2021 overview likewise found some empirical support but a strong need for randomized designs. Most of this work comes from authors within the Jungian field, and none of the sources reviewed compare Jungian therapy directly with another therapy in a trial.

Theory and criticism

Evidence for the outcomes of therapy does not test Jung's theories. Contributors to the 2018 Basel conference reported a majority questioning Jung's biological conceptualization of archetypes and favoring restatements from cultural theory or dynamic systems theory. In the encyclopedia entry, Magda Arnold argues that the collective unconscious is not required by clinical evidence, since imagination could explain recurring images, that the system was never stated in full in one work, and that Jung's theological writing reflects personal philosophy more than science.

Care boundaries and unwanted effects

Jungian analysis is a form of psychotherapy, and psychotherapy in general can produce unwanted effects. Linden and Schermuly-Haupt describe an emerging consensus that unwanted events should be expected in about 5 to 20 percent of psychotherapy patients, note that only 3 percent of 132 eligible randomized trials described adverse events with their collection methods, and list false memories as a recognized risk of unknown frequency. They caution that findings from one approach cannot be applied to another. The Jungian outcome papers reviewed here do not describe systematic monitoring of such effects. This page does not replace care, and necessary care should not be delayed or replaced.

The 2025 study also found no significant change in eating disorder symptoms, which its authors attributed to a likely need for specialized interventions. This is a reminder that outcome data from one pooled sample do not show that the approach suits every condition, and that people with a specific diagnosis may need care designed for it.

Training, ethics and registers

The IAAP states that societies on its training list are permitted to train candidates in Jungian analysis, with that status confirmed by a vote of delegates at its triennial congress. It maintains a Code of Ethics for individual members and an Ethics Committee that processes complaints against them, and requires member societies' own ethics codes to meet minimum standards. The IAAP pages reviewed do not say how this relates to national licensing, and no statutory regulation or training standard was reviewed here. Whether the title Jungian analyst is legally protected differs by place and is not established by these sources.

Jungian ideas outside clinical training

Books, workshops and self-directed practices that use Jungian vocabulary, such as shadow work, are not the same as analysis by a trained analyst, and the IAAP pages reviewed concern only the latter. The 2025 study authors describe Jungian psychotherapy as an established treatment in modern health care systems whose recognition and insurance coverage depend on empirical validation. Readers weighing a Jungian therapist can ask about training, supervision, registration with a professional body in their own jurisdiction, and how the therapist works with other clinicians when symptoms are severe.
