Systems-centered therapy and consultation developed by Yvonne Agazarian is based on the Theory of Living Human Systems, a theory that can be applied to any living human system as small as one individual or a large group and couples, families, classrooms, committees, businesses or even nations [REF].
The theory defines "a hierarchy of isomorphic systems that are energy-organizing, self-correcting and goal directed" - working on the assumption that psychic patterns will be repeated in the same form (isomorphy)at every nested level of interaction [REF].
