Psychiatrist vs Therapist vs Primary Care Doctor: Who Does What

Key points

A psychiatrist is a medical doctor with psychiatric training who can diagnose, prescribe and monitor medicine, and may also provide therapy.
Licensed counselors and clinical social workers provide talk therapy and help people build skills; they do not prescribe.
A primary care provider is often a good first stop and can screen for mental health concerns, prescribe some medicines and refer you on.
Many people see more than one of these professionals, and care tends to fit together best when they share information with your permission.

Three kinds of help, one goal

When you decide to get help for your mental health, the hardest part can be knowing whom to call. The good news is that there is no wrong door. Psychiatrists, therapists and primary care providers each play a part, and many people end up working with two or even all three.

The National Institute of Mental Health (NIMH) says treatment for mental illnesses usually includes therapy, medication or a combination of the two. Knowing who does what can help you start in the place that fits what you need right now, and know where to go next.

What a psychiatrist does

A psychiatrist is a licensed medical doctor who has completed training in psychiatry. According to the National Alliance on Mental Illness (NAMI), psychiatrists can diagnose mental health conditions, prescribe and monitor medications and provide therapy. They hold a Doctor of Medicine (MD) or Doctor of Osteopathic Medicine (DO) degree and have completed a residency in psychiatry.

Because they are physicians, psychiatrists can consider your physical health and the other medicines you take alongside your mental health symptoms. People often see a psychiatrist when they are wondering whether medication could help, when a medicine needs closer management, or when symptoms are complex or have not eased with other care.

Many psychiatric visits focus on diagnosis and medication, with follow-up visits to see how things are going. Some psychiatrists also offer therapy, so it is worth asking what a given psychiatrist provides.

What a therapist does

"Therapist" is a broad word. NAMI explains that master's-level clinicians work under titles such as counselor, clinician or therapist, with licenses that vary by state, such as Licensed Professional Counselor (LPC). Clinical social workers hold a master's degree in social work and licenses such as Licensed Clinical Social Worker (LCSW). Both are trained to evaluate a person's mental health and use therapeutic techniques.

NIMH describes psychotherapy, also called talk therapy, as a variety of treatments that aim to help a person identify and change troubling emotions, thoughts and behaviors. That can mean learning to question unhelpful thoughts, building coping and problem-solving skills, or working through relationship and family stress.

Counselors and social workers do not prescribe medication. A therapist can still help you think through whether medication is worth exploring and, with your permission, share what they see with a prescriber.

What a primary care provider does

A primary care provider (PCP) is the person you see first for checkups and everyday health problems. NIMH notes that a PCP is often a doctor but may also be a physician assistant or a nurse practitioner. MedlinePlus, from the National Library of Medicine, adds that a PCP may refer you to specialists, including psychiatry, when needed.

NIMH suggests that if you do not know where to start, you can raise mental health concerns at a primary care visit. A PCP can do an initial mental health screening and refer you to a mental health professional. NAMI notes that primary care physicians can prescribe medication, though you might consider seeing someone who focuses on mental health care.

A PCP visit has another benefit. NIMH explains that some symptoms, like a change in mood or trouble concentrating, can be due to a medical condition, so an exam can help rule out a physical cause.

When each may fit

Every situation is different, and these are general starting points rather than rules.

A primary care provider may fit if you are not sure what is going on, have not had a checkup in a while, or want a first conversation and a referral.
A therapist may fit if you want to talk things through, learn skills for stress, worry or low mood, or work on relationships and life changes.
A psychiatrist may fit if you are wondering about medication, already take a mental health medicine that needs managing, or have symptoms that feel complex or have not improved.
More than one may fit. Many people see a therapist and a prescriber at the same time, with their PCP looking after their overall health.

Common questions

Should I see a psychiatrist or a therapist first?

It depends on what you need. If you mainly want to talk things through and build skills, a therapist is a natural place to start. If you are wondering about medication or already take one that needs managing, a psychiatrist may fit. If you are unsure, a primary care provider can screen and refer you. Starting anywhere is a good step.

Can my primary care doctor prescribe mental health medication?

Often, yes. NAMI notes that primary care physicians can prescribe medication, and many people start there. You might also consider a professional who focuses on mental health, such as a psychiatrist, especially if your symptoms are complex or a medicine is not working as hoped. Your PCP can refer you.

Do psychiatrists do therapy?

Some do. NAMI says psychiatrists can diagnose, prescribe and monitor medications and provide therapy. In practice, many psychiatric visits focus on diagnosis and medication, and many people see a therapist separately for talk therapy. If you want both from one person, ask the psychiatrist what they offer before you book.

Do I need to be in therapy with you to see your psychiatrist?

Ask us when you reach out and we will explain the options for your situation. Our psychiatrist sees people by secure video who are physically located in Pennsylvania during each visit. If you do see one of our therapists as well, the two can coordinate your care with your permission.
