Group psychotherapy 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 elivered 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 explictly 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-solvong and psycoeducational groups are discussed by Momtgomery (2002).. Other, more specialised forms of group therapy would include non-verbal expressive therapies such as dance therapy, music therapy or the TaKeTiNa Rhythm Process.
