While there may be other groups that address the experience of hearing voices and other unusual or extreme experiences in some way, not all of those groups are members of the Hearing Voices Network (HVN) USA. Above all else, what defines a group as an HVN-USA Member is whether or not they operate in a way that is consistent with HVN values and approach. This Charter, adapted from the hard work and careful thought of many individuals connected with HVN England, identifies the qualities that define both affiliated and full group membership within HVN-USA. Only groups that clearly state that they follow the terms of this Charter will be listed on this site or considered to be HVN-USA members.
