If you’re looking for psychotherapy, psychological testing, or help deciding whether medication might be appropriate, either a psychologist or psychiatrist may be a starting point—but their training and typical roles differ. Psychiatrists are physicians who can prescribe medication; psychologists commonly provide psychotherapy and psychological assessment, and generally cannot prescribe unless local law and additional qualifications allow it. The right choice depends on the kind of help you want, the clinician’s expertise, and the rules where you live.
Psychologist vs. psychiatrist: the key differences
| Question | Psychologist | Psychiatrist |
|---|---|---|
| What is the training? | Graduate training in psychology, commonly at the doctoral level, with supervised clinical preparation and state licensure. Degrees and title rules vary by state. | Medical degree (MD or DO), followed by specialized residency training in psychiatry. |
| What care might they provide? | Psychotherapy, psychological assessment, testing, and diagnosis within their scope of practice. | Diagnosis and treatment, including medication and other medical treatments; psychiatrists may also provide psychotherapy. |
| Can they prescribe medication? | Generally not, unless the jurisdiction allows it and the psychologist has the required additional qualifications. | Yes. Psychiatrists are physicians and can prescribe medication. |
| When might you start here? | If psychotherapy, testing, or a detailed psychological evaluation is your main need, consider a psychologist whose specialty matches it. | If medication evaluation or medical assessment is a priority, consider a psychiatrist. |
These are common roles, not exclusive rules. Both professions can provide psychotherapy, and the services offered by an individual clinician depend on their training, specialty, and local scope-of-practice rules. The American Psychological Association explains the professions’ typical roles in its comparison of psychologists, psychiatrists, and social workers; the American Psychiatric Association describes psychiatrists as physicians with specialized psychiatry training in What is Psychiatry?.
When to consider a psychologist
You want psychotherapy
Psychologists commonly provide psychotherapy. A psychiatrist may provide it too, so ask any prospective clinician what treatment they offer, how they approach it, and whether they have experience with your concern. The clinician’s fit and expertise matter more than the title alone.

If you’re seeking a detailed psychological assessment or testing, look for a psychologist who specifically offers the relevant evaluation. Ask what the assessment covers, what you’ll receive afterward, and whether the clinician has experience with your reason for seeking it.

When to consider a psychiatrist
You want to discuss medication
A psychiatrist is a direct option for medication evaluation or management because psychiatrists are physicians who can prescribe. That does not mean every appointment will result in a prescription, or that medication is the only treatment they can offer.
You want a medical assessment as part of mental-health care
Psychiatrists bring medical training to diagnosis and treatment. If you want a clinician who can consider medication and other medical treatments, ask about their experience with your concerns and what their evaluation includes.

Can you see both?
Yes. When needs include both psychotherapy or assessment and medication management, a psychologist and psychiatrist may provide complementary care. With your permission, they can coordinate treatment. The American Psychological Association notes that care often benefits from the collaborative expertise of both professions in its FAQs for the public. Seeing both is an option, not a requirement.
How to choose a clinician
- Identify what you want help with. For psychotherapy, either profession may be appropriate. For psychological testing, seek a clinician who offers that specific evaluation. For medication evaluation, a psychiatrist is a direct choice; verify any psychologist’s prescribing authority rather than assuming it.
- Check credentials and local rules. Confirm the clinician’s current license and ask what their credentials authorize them to do. Professional titles, licensure requirements, and prescribing authority can vary by state and may change. MedlinePlus summarizes the general rule that psychologists do not prescribe unless specially authorized in its mental-health screening overview. The APA also discusses psychologists’ work and possible prescribing authority after additional training in some jurisdictions in What do practicing psychologists do?.
- Ask about relevant experience and approach. Find out whether the clinician regularly works with the concern you want to address, what treatment approaches they use, and how they’ll assess whether care is helping. The APA recommends asking potential therapists about credentials, experience, and approach in its guidance on psychotherapy professionals.
- Clarify practical details before starting. Ask what services the clinician provides, whether they prescribe or coordinate with a prescriber, and how availability, fees, and insurance work for your situation. Cost, coverage, and access depend on the provider, location, and plan.
- Consider whether you feel comfortable with them. A relevant license and specialty are important, but so is whether you can communicate openly and feel respected by the clinician.
Other routes to mental-health care
Psychologists and psychiatrists are not the only professionals who provide mental-health treatment. Depending on your needs and location, psychiatric nurse practitioners, clinical social workers, and licensed counselors may also be options. Check each person’s license, training, services, and local scope of practice before choosing.
