Group PsychotherapyGroup psychotherapy is a type of psychological treatment provided to several persons served simultaneously. In this form of treatment, individuals communicate about their experiences either verbally or nonverbally with both the therapist and their peers. Interactions between persons served are facilitated by the group therapist as a means of developing more effective communications with others. In addition, groups work together to learn to solve the various problems that are raised by its members. Finally, members of the group learn more effective ways to cope with the challenges associated with limited cognitive functioning, symptoms of mental illness, or problems with substance abuse.
