We find it very helpful for support people and consumers to talk with each other. When there are enough people at a support group to split into semi-groups, it's a wonderful opportunity for a particular pair to participate separately. It's not a matter of keeping secrets from one another, though we do insist on confidentiality. It's just that sometimes a person is not comfortable asking a question with a loved one sitting in the same circle. At a support group meeting, breaking into sub-groups of 4 to 8 people is more beneficial because everyone has a better chance of actively participating.
Support groups are limited time-wise and everyone deserves chances to speak, as well as listen.
Confidentiality is so important. We want our participants to feel safe in expressing their questions or thoughts. We insist that whatever is said within a particular group's circle stays there. The only exception to that rule is in the event that someone indicates he or she may be a danger to his or her self, or to someone else. Though a person may actually be a professional therapist, doctor, lawyer, etc., at our support groups all participants are volunteers, volunteering to support one another and be supported.
