How effective and helpful group therapy is depends on a number of factors (such as the nature and severity of the problem a person may be facing), but disadvantages can include personality clashes in the group, causing individuals to feel uncomfortable, or feelings of rejection from individuals when trying to relate to the therapist. In general, patients with severe conditions that hamper everyday social interaction are not suited to group therapy.
Group therapy should not be undertaken if the patient or individual is in a fragile emotional state, as any clashes or aggressive behavior exhibited by other group members towards one another or the individual may cause more harm than good.
Additionally, an individual may find it harder to share personal emotions, thoughts, and experiences with a group. In this case, traditional one-to-one therapy is preferable.
There are however, a number of advantages to group therapy. Firstly, some individuals may find sharing their experience with other people in a similar position both comforting and insightful. Many group therapy sessions are split into smaller subgroups or pairs, which can help build an ever-growing support network for people suffering similar problems. Group therapy can also help to encourage positive behavior through praise and compliments from other members.
