member's behaviour and impact on others. Self-understanding This factor overlaps with interpersonal learning but refers to the achievement of greater levels of insight into the genesis of one's problems and the unconscious motivations that underlie one's behaviour. Settings Group therapy can form part of the therapeutic milieu of a psychiatric in-patient unit or ambulatory psychiatric partial hospitalization (also known as day hospital treatment). 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 and dance/movement 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. However, interactions between the culture of group psychotherapeutic settings and the more managerial norms of external authorities may create 'organizational turbulence' which can critically undermine a group's ability to maintain a safe yet challenging 'formative space'. Academics at the University of Oxford studied the inter-organizational dynamics of a national democratic therapeutic community over a period of four years; they found external steering by authorities eroded the community's therapeutic model, produced a crisis, and led to an intractable conflict which resulted in the community's closure. A form of group therapy has been reported to be effective in psychotic adolescents and recovering addicts. 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. It was popularized in the science fiction novel, Red Orc's Rage. Group therapy is now often utilized in private practice settings. Group analysis has become widespread in Europe, and especially the United Kingdom, where it has become the most common form of group psychotherapy. Interest from
