What is the difference between a psychiatrist and a psychologist?

The distinction that a psychiatrist is a medical doctor who can prescribe medication is accurate and highlights a key difference between psychiatrists and psychologists. Psychiatrists have completed medical school and obtained an MD or DO degree, allowing them to understand the biological aspects of mental health disorders and to prescribe medication as part of treatment. This medical training equips them to address complex psychiatric conditions that may require pharmacological intervention.

In contrast, psychologists typically hold doctoral degrees in psychology (PhD or PsyD) and are trained primarily in therapeutic techniques, psychological assessment, and research. While psychologists can provide therapy and support for mental health issues, their education does not generally include medical training that would allow them to prescribe medications. This fundamental difference in training and scope of practice is essential for understanding the roles of these two professions within the field of mental health.
