What is the difference between a psychologist and a psychiatrist?
Last updated September 3, 2026.
A psychiatrist is a medical doctor who can prescribe; a psychologist holds a psychology doctorate and specializes in therapy and testing. The common division of labor: a psychiatrist or primary care doctor manages medication, while a psychologist or another licensed therapist - social workers and counselors also deliver therapy, per NIMH - does the weekly therapy work. Main need is medication: start with a prescriber. Main need is patterns, trauma, or skills: start with a therapist. Unsure: either can triage you.
What to do
- Match the door to the need. Medication questions: prescriber. Talk therapy: psychologist or licensed therapist.
- Use primary care as a valid door. Family doctors manage common antidepressants routinely.
- Expect collaboration. Seeing both for the same problem is normal and often ideal.
- Check the license, not the title. Whatever the letters, the state license is the check. In crisis: 988 in the US, or your local crisis line.
