Medical Psychology

Medical psychology is the application of psychological principles to the practice of medicine for both physical and mental disorders. The American Psychological Association (APA) defines medical psychology as "that branch of psychology that integrates somatic and psychotherapeutic modalities into the management of mental illness and emotional, cognitive, behavioral and substance use disorders". A medical psychologist does not automatically equate with a psychologist who has the authority to prescribe medication.

Medical psychologists apply psychological theories, scientific psychological findings, and techniques of psychotherapy, behavior modification, cognitive, interpersonal, family, and life-style therapy to improve the psychological and physical health of the patient. Clinical psychologists with post doctoral specialty training as medical psychologists are the practitioners with refined skills in clinical observation in of the field of psychology, learning, central nervous system adaptation and change, and adaptation and lifestyle change applying a number of different methods in several different mediums of treatment. Highly qualified and post graduate specialized doctors are trained for service in primary care centers, hospitals, residential care centers, and long-term care facilities and in multidisciplinary collaboration and team treatment. They are trained and equipped to modify physical disease states and the actual cytoarchitecture and functioning of the central nervous and related systems using psychological and pharmacological techniques (when allowed by statute), and to provide prevention for the progression of disease having to do with poor personal and life-style choices and conceptualization, behavioral patterns, and chronic exposure to the effects of negative thinking, choosing, attitudes, and negative contexts.
