Why Psychologists Should Not Be Licensed
to Prescribe Psychiatric Drugs

Stephen Barrett , M.D.

Since 2002, the American Psychological Association and many state psychological associations have sought passage of state laws that would enable psychologists to prescribe psychiatric medications to their patients [1]. Psychologists have also stepped up efforts to establish psychopharmacology training programs [2].

In March 2002, New Mexico became the first state to authorize psychologist prescribing. Its law (HB 170) enabled psychologists to acquire a two-year license to prescribe under physician supervision by:

Then, if the supervisor approves and the psychologist's prescribing records pass an independent peer review, the psychologist can apply to prescribe independently. To maintain prescribing abiltiy, the psychologist must carry malpractice insurance, complete 20 hours of continuing education annually, and collaborate with the patient's primary physician. The new law also enables prescribing psychologists to order relevant laboratory tests.


The key question is whether training of this type will enable psychologists to prescribe safely and effectively for their patients. The American Medical Association, the American Psychiatric Association, the American Academy of Child and Adolescent Psychiatry, the American Society for Geriatric Psychiatry, and many individual psychologists believe that the answer is no. I agree with this position.

The American Psychiatric Association labeled New Mexico's new law "the result of a cynical, economically-motivated effort by some elements of organized psychology to achieve legislated prescriptive authority without benefit of medical education and training." In a strongly worded statement, APA president Richard K. Harding, M.D., said:

We believe that the legislature and the governor in New Mexico have placed patient health and safety at risk. . . . By virtue of their training and education, psychologists simply do not have the background or experience to safely and effectively use powerful medications in the treatment of mental illnesses. Psychologists have always had a clear path to prescribing privileges: medical school. No psychology-designed and administered crash course in drug prescribing can substitute for the comprehensive knowledge and skills physicians achieve through medical education and rigorous clinical experience. . . .

Over the past decade, 14 state legislatures have rejected psychology prescribing legislation after objectively considering the scientific data and the public health risks of placing potent medications for treatment of mental illness in the hands of people with no medical education or residency training. We hope that they will continue to do so in the future [3].

The Society for the Science of Clinical Psychology (SSCP), a section of the American Psychological Association, has also opposed psychologist prescribing. Its members have been concerned not only that patients will be improperly treated, but also that psychologists will face serious legal risks. In 2001, SSCP members voted 98-6 to adopt a position statement which said (in part):

In 2004, the American Society for Geriatric Psychiatry adopted a similar position:

Inherent Risks

I oppose psychologist prescribing because I don't see how it is possible for a one-year course to adequately prepare nonphysicians to prescribe psychatric drugs. To properly prescribe drugs, it is necessary to know when they should be prescribed, when they should not be prescribed, how they might interact with other drugs, what side effects might occur, and what to do when adverse effects do occur. If new symptoms occur, it is important to know whether they are related to taking a drug or represent a new problem that requires medical care.

Psychiatrists undergo four years of medical school during which they learn biochemistry, physiology, pharmacology, and diagnosis. Then they have at least three years of full-time postgraduate psychiatric training during which they typically prescribe drugs (under supervision) for hundreds of patients. And once in practice, the vast majority learn more by reading journals, talking with colleagues, and attending continuing education courses. I don't see how a part-time one-year course can provide anything comparable for psychologists.
