Group Therapy is a form of psychotherapy in which one or more therapists treat a small group of patients to describe and discuss their problems. Group therapy allows individuals to develop self-awareness and better understand themselves by listening to others with similar issues in the context of their relationships.
An advantage to group therapy is that groups are source for social support.
