A short-term psycho-educational group of six to eight Members is the ideal setting for this activity. Since boundary issues are related to many presenting problems, the exercise may be included in various types of groups, such as those meant to address addictions, abuse, codependency, women's issues and men's issues. The method usually involves some degree of action on the clients' part, either physical or imagined'. In this intervention, the Therapist asks group Members to change chairs, and then discuss their reactions. The focus of the exercise is on interpersonal boundaries. The exercise is quite stimulating and will require plenty of time to process. Some time in the middle of the group, after Members have had some time to establish their 'place' in the group, but well before the group ends, to leave time for discussion, a session should be dedicated to the experiential exercise of changing chairs.
