How are psychologists and psychiatrists different?

Training, experience: Psychiatrists are physicians who have graduated from 4 years of medical school with an md or do degree; they then serve 4 year residencies that cover general medical services plus psychiatry in training. Psychologists enter professional training programs after college; a master's level requires 2 years' graduate work. A phd level generally requires 3-5 years' graduate study & a dissertation.

Physician vs Not: I agree with dr. Pappas' response on their training. Psychiatrists are physicians, and think as physicians. We evaluate the entire patient, from both a medical/biological perspective, as well as a psychological one. We then establish a diagnosis, cause of illness, other medical illnesses, prognosis, and finally treatment options, which may include medications and psychotherapy.

Therapy vs meds: Speaking very generally, most psychologists hold either a PhD or a PsyD degree (I hold both) and practice psychotherapy. Psychiatrists hold either an MD or a DO degree, and they prescribe psychotropic medications, and generally do not do all that much therapy these days, but years ago psychiatrists would do both.

Psychologists : Psychologists are licensed in the state they practice and have training to treat mental health issues. Psychiatrists are medical doctors that have gone to medical school and have specialized in psychiatry. They can prescribe medication and typically that is the focus of their work. Psychologists work with people interpersonally to help identify issues by talking.
