treatment of psychological problems in which two or more participants interact with each other on both an emotional and a cognitive level in the presence of one or more psychotherapists who serve as catalysts, facilitators, or interpreters. The approaches vary, but in general they aim to provide an environment in which problems and concerns can be shared in an atmosphere of mutual respect and understanding. Group therapy seeks to enhance self-respect, deepen self-understanding, and improve interpersonal relationships. Also called group psychotherapy. Compare individual therapy.
