The Difference Between a Psychiatrist and a Psychologist

Outside the medical profession, there is confusion about the difference between psychologists and psychiatrists. Both are doctors trained to assess, diagnose and care for behavioral, emotional and developmental disorders - but there are some significant differences.

What is a Psychiatrist?

A psychiatrist has an M.D. (medical degree), will have graduated from medical school, completed a medical internship, done three years of residency in adult psychiatry and two years of additional training in child and adolescent psychiatry if they work with children. Because of their training, psychiatrists have a deep understanding of a person’s brain chemistry and as medical doctors, they can prescribe medications if the treatment calls for it.

What is a Psychologist?

Psychologists have doctoral degrees in psychology, either a research-based Ph.D. or clinically-based Psy.D. They are not medical doctors and cannot prescribe medications. Rather, psychologists take a more behavioral approach to care, using various therapeutic techniques. They also have extensive training in psychometric assessment or testing for IQ and learning disabilities.
