Mental illness is a serious problem in the United States. Based on “current epidemiological estimates, at least one in five people has a diagnosable mental disorder during the course of a year.” Fortunately, many of these disorders respond positively to psychotropic medications. While psychiatrists write some of the prescriptions for psychotropic medications, primary care physicians write more of them. State legislatures, seeking to expand patient access to pharmacological treatment, granted physician assistants and nurse practitioners prescriptive authority for psychotropic medications. Over the past decade other groups have gained some form of prescriptive authority. Currently, psychologists comprise the primary group seeking prescriptive authority for psychotropic medications.The American Society for the Advancement of Pharmacotherapy (“ASAP”), a division of the American Psychological Association (“APA”), spearheads the drive for psychologists to gain prescriptive authority. The American Psychological Association offers five main reasons why legislatures should grant psychologists this privilege: 1) psychologists’ education and clinical training better qualify them to diagnose and treat mental illness in comparison with primary care physicians; 2) the Department of Defense Psychopharmacology Demonstration Project (“PDP”) demonstrated non-physician psychologists can prescribe psychotropic medications safely; 3) the recommended post-doctoral training requirements adequately prepare psychologists to prescribe safely psychotropic medications; 4) this privilege will increase availability of mental healthcare services, especially in rural areas; and 5) this privilege will result in an overall reduction in medical expenses, because patients will visit only one healthcare provider instead of two–one for psychotherapy and one for medication.
