Group psychotherapy or group therapy is a form of psychotherapy in which one or more therapists treat a small group of clients together as a group. The term can legitimately refer to any form of psychotherapy when delivered in a group format, including Cognitive behavioural therapy or Interpersonal therapy, but it is usually applied to psychodynamic group therapy where the group context and group process is explicitly utilised as a mechanism of change by developing, exploring and examining interpersonal relationships within the group. The broader concept of group therapy can be taken to include any helping process that takes place in a group, including support groups, skills training groups (such as anger management, mindfulness, relaxation training or social skills training), and psycho-education groups. The differences between psychodynamic groups, activity groups, support groups, problem-solving and psycoeducational groups are discussed by Montgomery (2002).[1] Other, more specialised forms of group therapy would include non-verbal expressive therapies such as dance therapy, music therapy or the TaKeTiNa Rhythm Process.

The founders of group psychotherapy in the USA were Joseph H. Pratt, Trigant Burrow and Paul Schilder. All three of them were active and working at the East Coast in first half of the 20th century. After World War II group psychotherapy was further developed by Jacob L. Moreno, Samuel Slavson, Hyman Spotnitz, Irvin Yalom, and Lou Ormont. Yalom's approach to group therapy has been very influential not only in the USA but across the world, through his classic text "The Theory and Practice of Group Psychotherapy".[2] Moreno developed a specific and highly structured form of group therapy known as Psychodrama. Another recent development is the theory and method of group psychotherapy based on an integration of systems thinking is Yvonne Agazarian's "systems-Centered" approach (SCT), which sees groups functioning within the principles of system dynamics. Her method of "functional subgrouping" introduces a method of organizing group communication so it is less likely to react counterproductively to differences. SCT also emphasizes the need to recognize the phases of group development and the defenses related to each phase in order to best make sense and influence group dynamics.
In the United Kingdom group psychotherapy initially developed independently, with pioneers S. H. Foulkes and Wilfred Bion using group therapy as an approach to treating combat fatigue in the Second World War.[3] Foulkes and Bion were psychoanalysts and incorporated psychoanalysis into group therapy by recognising that transference can arise not only between group members and the therapist but also among group members. Furthermore the psychoanalytic concept of the unconscious was extended with a recognition of a group unconscious, in which the unconscious processes of group members could be acted out in the form of irrational processes in group sessions. Foulkes developed the model known as Group Analysis and the Institute of Group Analysis, while Bion was influential in the development of group therapy at the Tavistock Clinic. Bion has been criticised, for example by Yalom,[4] for his technical approach which had an exclusive focus on analysis of whole-group processes to the exclusion of any exploration of individual group members' issues. Despite this, his recognition of group defences in the "Basic Assumption Group", has been highly influential.[5][6]
Bion's approach is comparable to Social Therapy, first developed in the United States in the late 1970s by Lois Holzman and Fred Newman, which is a group therapy in which practitioners relate to the group, not its individuals, as the fundamental unit of development. The task of the group is to "build the group" rather than focus on problem solving or "fixing" individuals.
Yalom's therapeutic factors (originally termed curative factors but re-named therapeutic factors in the 5th edition of 'The Theory and Practice of Group Psychotherapy')[7] are derived from extensive self-report research with users of group therapy.[8][9]
Group therapy can form part of the therapeutic milieu of a psychiatric in-patient unit[11][12] or ambulatory psychiatric Partial hospitalization (also known as Day Hospital treatment).[13] In addition to classical "talking" therapy, group therapy in an institutional setting can also include group-based expressive therapies such as drama therapy, psychodrama, art therapy, and non-verbal types of therapy such as music therapy. Group psychotherapy is a key component of Milieu Therapy in a Therapeutic Community. The total environment or milieu is regarded as the medium of therapy, all interactions and activities regarded as potentially therapeutic and are subject to exploration and interpretation, and are explored in daily or weekly community meetings[14]
A form of group therapy has been reported to be effective in psychotic adolescents and recovering addicts.[15] Projective psychotherapy uses an outside text such as a novel or motion picture to provide a "stable delusion" for the former cohort and a safe focus for repressed and suppressed emotions or thoughts in the latter. Patient groups read a novel or collectively view a film. They then participate collectively in the discussion of plot, character motivation and author motivation. In the case of films, sound track, cinematography and background are also discussed and processed. Under the guidance of the therapist, defense mechanisms are bypassed by the use of signifiers and semiotic processes. The focus remains on the text rather than on personal issues.[16] It was popularized in the science fiction novel, Red Orc's Rage.
Group therapy is now often utilized in private practice settings (Gardenswartz, 2009, Los Angeles, CA).
There is clear evidence for the effectiveness of group psychotherapy for depression: a meta-analysis of 48 studies showed an overall effect size of 1.03, which is clinically highly significant.[17] Similarly, a meta-analysis of five studies of group psychotherapy for adult sexual abuse survivors showed moderate to strong effect sizes,[18] and there is also good evidence for effectiveness with chronic traumatic stress in war veterans.[19] There is less robust evidence of good outcomes for patients with borderline personality disorder, with some studies showing only small to moderate effect sizes.[20] The authors comment that these poor outcomes might reflect a need for additional support for some patients, in addition to the group therapy. This is borne out by the impressive results obtained using Mentalization based treatment, a model that combines dynamic group psychotherapy with individual psychotherapy and case management.[21] Most outcome research is carried out using time-limited therapy with diagnostically homogenous groups. However, long-term intensive interactional group psychotherapy[22] assumes diverse and diagnostically heterogeneous group membership, and an open-ended time scale for therapy. Good outcomes have also been demonstrated for this form of group therapy.[23] Group Therapy has been shown to be as or more effective than individual therapy for higher functioning adults (Gardenswartz, 2009, Los Angeles, CA). Clinical cases has shown that the combination of both individual and group therapy is most beneficial for such clients. (the "multiplicative" effect).
