ABSTRACT
Sometimes a theoretical perspective may not be explicit or only vaguely specified, but it is always present. Theories are reflected in the knowledge bases which group leaders and participants draw upon and the language they use to explain them. A further complication in distinguishing theoretical perspectives arises from the fact that different types of groups—for example, psychotherapy and psychoeducational groups—can (and often do) proceed from similar theoretical bases. Definitions offer potential meanings at best, but they do point us towards grasping various theoretical perspectives which are embedded—although rarely articulated—values, beliefs and assumptions. The theoretical perspectives which take the concept of the group as a power base originate in Marxist political philosophy and sociology. A key theoretical component is the concept of praxis—the process whereby the theoretical understanding achieved by the group is implemented in the action taken. Reflection on that action may result in theoretical change, a change in action, and so on.
