What Does a Psychiatrist Do? From First Visit to Follow-Up

Someone told you to “see a psychiatrist,” and you’re not sure what that actually involves. Will they just hand you a prescription? Will they make you lie on a couch? And how long will it take to even get in the door?

Mental health symptoms live at the meeting point of brain, body, and life circumstances. Emotional and physical illnesses often affect each other, so sorting out what’s driving your symptoms takes medical precision as well as careful listening.

That’s the traditional role of the psychiatrist. According to the American Psychiatric Association, a psychiatrist is a medical doctor trained to understand the complex relationship between emotional and other medical illnesses, assess both the mental and physical sides of psychological problems, order lab tests, diagnose, prescribe, and provide therapy. That model is well established.

But the specialist model only helps if you can reach it, and we think a long wait shouldn’t stand between you and understanding what’s going on.

This guide explains what psychiatrists do, what happens at a first evaluation and afterward, how they differ from other clinicians, and why appointments are so hard to get. It’s grounded in professional guidelines and published research, so you’ll know what to expect before you walk in.

What Is a Psychiatrist?

A psychiatrist is a medical doctor, either an MD or a DO, who specializes in mental health, including substance use disorders. The American Psychiatric Association describes the training path: medical school, a license to practice medicine, and a four-year psychiatry residency. That typically adds up to about 12 years of education after high school, and up to 14 for child and adolescent psychiatry.

The first residency year usually involves caring for patients with a wide range of medical illnesses. Most psychiatrists then take a voluntary exam from the American Board of Psychiatry and Neurology to become board certified, and some complete fellowships in areas such as addiction, geriatric, or consultation-liaison psychiatry. The APA estimates there are about 50,000 psychiatrists in the U.S.

Because they’re physicians, psychiatrists can order or perform medical laboratory and psychological tests. That matters when physical conditions or medications might be contributing to how you feel.

What Happens at a First Psychiatric Evaluation?

A first evaluation is a structured conversation about your whole history. The APA’s psychiatric evaluation guidelines recommend that an initial evaluation cover nine areas:

• Your current symptoms, trauma history, and past psychiatric treatment
• Use of tobacco, alcohol, other substances, and any misuse of medications
• Suicide risk, including current and past thoughts
• Risk of aggressive behavior
• Cultural factors and personal beliefs about illness
• Medical health, including all current medications and supplements
• Symptom ratings using standardized questionnaires
• Your goals and preferences, so treatment decisions are shared
• Clear documentation of the evaluation

The APA rates the research evidence behind these recommendations as low, mostly because evaluation approaches are hard to study in controlled trials. The recommendations instead weigh likely benefits against harms, informed by a survey of experts in psychiatric evaluation.

To make the most of the visit, bring a list of every medication and supplement you take, any past diagnoses, and notes on what has or hasn’t helped. Our guide on what to tell your psychiatrist about medication covers the details, and our explainer on the mental status exam describes one part of the evaluation.

What Treatments Can a Psychiatrist Provide?

Psychiatrists use a range of treatments depending on your needs, according to the APA. These include medications, several forms of talk therapy, and procedures such as electroconvulsive therapy (ECT) and transcranial magnetic stimulation (TMS) when other treatments haven’t worked.

Therapy has become a smaller part of most psychiatrists’ work. A national study of office-based psychiatry visits found that the share including psychotherapy fell from 44.4% in 1996 to 1997 to 28.9% in 2004 to 2005. The decline coincided with changes in reimbursement, growth in managed care, and more prescribing of medications. Today, many people see a psychiatrist for evaluation and medication and a therapist for ongoing therapy.

What Happens After the First Visit?

Treatment is a process, and follow-up is where much of the work happens. The APA notes that people on long-term medication need periodic visits to monitor how well it’s working and any side effects.

The early months deserve the closest attention. Antidepressant labels, such as escitalopram’s FDA label, advise monitoring patients closely for worsening symptoms and suicidal thoughts during the first few months and after any dose change.

Psychiatrists increasingly work as part of a team. Collaborative care, an approach modeled on chronic disease management, brings primary care and mental health professionals together around a shared plan. A Cochrane review of 79 randomized trials with 24,308 participants found that collaborative care improved depression and anxiety outcomes compared with usual care.

How Is a Psychiatrist Different From Other Clinicians?

Several types of clinicians diagnose and treat mental health conditions, and some prescribe medication. The summary below comes from the American Psychiatric Association’s overview of mental health professionals.

Clinician	Training	Main Work
Psychiatrist	MD or DO plus psychiatry residency	Evaluation, diagnosis, medication, therapy
Psychiatric nurse practitioner	RN plus master’s or doctorate in psychiatric nursing	Diagnosis, counseling, medication management
Psychiatric physician assistant	Master’s in PA studies, collaborates with psychiatrists	Evaluations, treatment plans, prescribing
Psychologist	PhD or PsyD	Testing, diagnosis, psychotherapy
Therapist or counselor	Master’s degree	Evaluation and therapy

Why Is It So Hard to Get an Appointment?

Demand far outpaces supply. In a secret shopper study conducted in 2022, researchers called 948 psychiatrists in New York, California, North Dakota, Virginia, and Wyoming. Only 18.5% were available to see new patients. The median wait was 67 days for an in-person appointment and 43 days for telepsychiatry. The most common reason for unavailability was not accepting new patients, and rural areas had fewer mental health resources than urban ones.

While you wait, your primary care clinician can often provide first-line treatment or a referral, according to the APA, and telepsychiatry appointments had shorter waits in the study above. Our guide to finding a psychiatrist online walks through options.
