There are many factors behind the growing advocacy movement for mentally ill individuals. These factors include the prevalence of mental illness in society, deinstitutionalization, the restrictions of managed care, an increased awareness of the rights of the mentally ill, and empowerment of mentally ill clients. Despite the growing importance of advocacy groups, information regarding who they are, what they do, and how to access them is not readily available. This paper is designed to provide counselors with this information. The wide range of service provided by advocacy groups is presented. A list is provided that can be utilized as a quick reference to some of the largest advocacy groups currently in existence. The history of each group and contact information are included. A list of organizations that can provide information on other groups, internet resources, and two useful directories are also included. (MKA)
