What is Division 18?

Division 18 (Psychologists in Public Service) is one of the divisions of the APA. Division 18 responds to the needs of the public in areas such as psychological practice, research, training, and policy development and implementation. The division has six sections representing a variety of settings: Community and State Hospital, Criminal Justice, Police and Public Safety, Serious Mental Illness-Severe Emotional Disturbance, Students, and Veterans Affairs. Division 18 and its sections provide a forum for its members to discuss common professional interests, to advocate for the mental health needs of the public, and to promote the use of evaluation and research in public research programs.

Who are public service psychologists?

Public service psychologists are practitioners, researchers, university professors, legislators, program developers, clinical coordinators, managers, administrators, and more. Their clients include consumers of mental health services, organizational managers, administrators, policy makers, elected officials, and the public. Public service psychologists can be found working for or with clients in state and community psychiatric facilities and clinics, medical centers, Veteran’s Affairs hospitals and clinics, correctional institutions such as jails and prisons, Indigenous Nations healthcare centers, community safety departments such as law enforcement and first-responder emergency services, state legislatures, and academic institutions. In general, the services they provide are as varied as the persons they serve and the places they work.

Public service psychologists also help train more than half the clinical and counseling psychologists in the United States through public service predoctoral internship sites; many of these sites end up hiring their interns.  Many also provide post-doctoral research and clinical training, not only to psychologists, but to other allied health professionals.
