History

Moreno developed a specific and highly structured form of group therapy known as psychodrama (although the entry on psychodrama claims it is not a form of group therapy). Another recent development in the theory and method of group psychotherapy based on an integration of systems thinking is Yvonne Agazarian 's systems-centered therapy (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.
