THE THERAPIST(S) The therapist should maintain a professional relationship with the participants all the time and no more than that. Any relationship with a participant may result in a "dual relationship" and may affect the goals of the session.
No Socializing with Group Members Group therapy is not a social activity, it is (hopefully!) a therapeutic one. Forming close friendships or other bonds with group members can interfere with group success, especially if members become hesitant to share personal information because of another group member. Friendships should be saved for after the group has disbanded.
Participate Group therapy doesn’t have much of a therapeutic effect if the members do not participate! While there will be times when you don't feel up for speaking, show up and try your best. The potential for healing and growth rests on how much group members are able to connect, share, and learn from one another. It is essential for all group members to truly participate for this treatment to be effective.
