Psychiatry vs. Psychology: Understanding the Differences and Similarities

When someone presents with a mental disorder or disease, who comes first, the psychiatrist or psychologist? Psychiatry and psychology have a lot in common. Both clinicians are trained to improve mental well-being. Practitioners and providers must be licensed nationally or in their state, and they must abide by a strict code of ethics to support their patients. The collaboration between the discourses of psychiatry and psychology leads to better outcomes for patients. At Apogee Behavioral Medicine, we work together to design treatment plans for disorders and commonly rely on each other’s expertise. Collaboratively, we want to explore, debunk, and educate our community about the differences and similarities between psychiatry and psychology, and how they work in concert.

First, let’s define the fields.

Psychiatry is a specialized branch of medicine that focuses on the diagnosis, treatment, and prevention of mental disorders. Providers and practitioners of psychiatry, or Psychiatrists, hold advanced medical degrees and can prescribe medication, diagnose disorders, conduct medical tests, and also offer psychotherapy.

Psychology is the broader study of the human mind and behavior. Psychologists also usually hold advanced doctoral degrees, but these degrees alone do not give them the capability to administer medical interventions or prescribe medication. Ever asked the question “why” or heard even the smallest of children asking why? This is the cornerstone of psychology: the study of mental processes, emotions, and behaviors through research, assessment, and therapeutic interventions.

Psychiatrists lead medical interventions, and since they prescribe mind-altering medication, they must undergo rigorous medical training that includes medical school and residency in psychiatry, 8 years of total advanced training. Psychiatrists have an expert level of understanding of psychology, and also an expert level of understanding of neurology and the mechanisms of biology regarding medical indications and contraindications of medical treatments.

Psychologists follow a similar academic track; however, their advanced doctoral degrees involve coursework, research, and clinical training. The length and breadth of training depend on the licensing procedure of the state and the type of advanced specialization they hold. Many psychologists hold advanced licenses for specialized treatments, but all are experts in psychological theories, conducting assessments, and crafting treatment plans.

Psychiatrists may adopt a biopsychosocial approach. This methodology considers biological, psychological, and social factors in concert when diagnosing mental disorders. They may prescribe medications, offer psychotherapy, or recommend other interventions like ECT or TMS. There are many painless treatments, like TMS, that physically change brain chemistry and deliver relief to those suffering from PTSD, anxiety, and other disorders. Psychiatrists use talk therapy as well, which is another reason that confusion exists between psychologists and psychiatrists.

Psychologists specialize in various therapeutic approaches, such as cognitive behavioral therapy, psychoanalysis, or family therapy. Both psychiatrists and psychologists study environmental and social factors in presenting disorders. Psychologists are trained more specifically in theories and talk therapy surrounding persistent patterns of thought, dissociation, primary relationships, and trauma. While psychologists do not prescribe medications, their psychological interventions are part of addressing a client’s needs in a holistic way.

Despite the roles and semantics of psychiatrists and psychologists, they are not at all at odds and part of their professional duty, and, in the case of the psychiatrist, the Hippocratic oath, they collaborate to provide comprehensive care. When a patient seeks medical or behavioral intervention, an interdisciplinary ensures that the treatment plan addresses the biological and psychological aspects of a patient’s condition. All parties are looking for an effective outcome for a patient.

Collaboration between fields and providers extends beyond patient care, and both rely on each other in building research and new tools to treat mental illness and neurological disorders. Psychologists and psychiatrists collaborate on studies and can contribute to innovations in patient care, neurological understanding, and how to treat new mental illnesses. Both psychiatry and psychology are evidence-based practices so incorporating the latest research into clinical decision-making ensures their interventions are sound.

Working together to improve outcomes through continued learning, collaboration, and research ensures that we, as a field, meet the challenges of future generations.
