There are two distinct types of groups, open groups, and closed groups. Open groups are groups in which new members are welcome to join at any time. Closed groups are groups in which all members begin group at the same time and/or group members attend consistently. Some of the most common forms of group therapy include psychoeducation groups, skill-building groups, and process groups. Psychoeducation groups prioritize educating the group on a specific topic. Skill-building groups emphasize teaching and practicing effective skills. Lastly, process groups focus on allowing the group to process openly any present concerns, feelings, and/or struggles. Each of these group therapy groups provides many benefits.
