All verbal and nonverbal information mentioned before, during, and following group meetings is to remain confidential. It is not to be mentioned to anyone outside the group including your spouse, significant other, or others that are close to you, even if you think you can trust these individuals with the information without it being shared. There are no exceptions to this rule

The law requires me to notify the authorities if you reveal that you are abusing children or if you express intent to harm yourself or to harm other people. In addition, I may share information with colleagues internally in this organization during supervision or consultation meetings about this group. Generally, no last names will be used when this information is shared, and the members of the staff of this organization are bound by confidentiality and will not share the information with others.

If you reveal confidential information in the group, this information may be spoken about outside the group by other members of the group, even though confidentiality has been requested of all group members. You could be hurt emotionally and economically if your confidences are told outside the group. Group leaders like myself, and this organization, may not be able to prevent other members' breaking the confidentiality agreement

Other members of this group may tell confidential information to you. If you repeat these confidences outside the group, the member whose confidential information you tell may have legal grounds to sue you for telling the confidential information to someone outside the group
