The selection process for group therapy should prioritize individuals who share similarities in their problems.

Selection of Individuals in Group Therapy

A common practice in group therapy is to arrange seating in a circle. This formation helps facilitate open conversation and ensures all participants can see one another. In addition to the layout, it is important to provide enough similar chairs for all members and to leave an absent member's chair vacant to maintain group consistency.

Seating Arrangements in Group Therapy

The frequency of group sessions in Group Therapy can vary, ranging from once a week to 3-4 times a day, depending on the specific needs of the group members and clinical setting. If groups are conducted on a daily basis, each session may last approximately 45 minutes. However, when held once a week, sessions may extend up to 90 minutes.
