The Difference Between a Psychologist and a Psychiatrist

Psychiatrists and psychologists are two key types of mental health professionals. Both hold advanced degrees, undergo clinical training in the diagnosis and care of people with mental health conditions, and must be licensed in the state where they practice. Both may also participate in research that advances the understanding and treatment of mental illness.

Psychiatrists

Psychiatrists are medical doctors (MDs or DOs). They complete medical school followed by a residency in psychiatry and are licensed as physicians. Because of their medical training, psychiatrists are equipped to understand how medical conditions, brain chemistry, and physical health interact with mental health. Psychiatrists can diagnose mental health disorders, order lab tests, and prescribe medication. Some psychiatrists also provide psychotherapy, though many primarily focus on medication management.

Psychologists

Psychologists typically complete a doctoral degree in psychology (PhD or PsyD). Their training involves research, clinical coursework, and several years of supervised practice. Psychologists are licensed at the state level (e.g., California Board of Psychology; New York State Office of the Professions). Psychologists specialize in psychological testing, diagnosis, and psychotherapy.

Medication and therapy: two possible approaches to treatment

One major distinction between the two professions is that psychiatrists, as medical doctors, can prescribe medication. Both psychiatrists and psychologists are trained to provide psychotherapy, but in practice, psychiatrists often focus on pharmacological treatment, while psychologists and other mental health clinicians primarily provide psychotherapy.

In many cases, psychiatrists and psychologists collaborate to provide integrated care; psychiatrists managing medications and psychologists offering therapy. Some psychiatrists continue to provide both psychotherapy and medication management.

Research has clearly established that both therapy and medication are effective; both have the power to influence how the brain functions, and both have the power even to alter how genes function. Research has also clearly established that whatever the treatment administered, a huge factor in its effectiveness is the nature of the provider-patient relationship. A relationship of trust and respect between patient and provider makes a significant clinical difference no matter the professional degree the provider holds.

Insurance coverage differences

In the United States, both psychiatrists and psychologists may accept insurance, but coverage varies widely by plan and provider. Many psychiatrists and psychologists do not participate in insurance networks, meaning patients pay out of pocket and may seek partial reimbursement through out-of-network benefits.

Psychiatry visits are often billed as medical appointments with a copay, while therapy sessions may be subject to session limits or prior authorization. Before scheduling an appointment, it is important to confirm whether the provider is in-network, what your copay or coinsurance will be, and whether a referral is required, as costs can vary significantly.

How do I know whether to see a psychiatrist or psychologist?

There are some complex conditions that generally require psychiatric care, including medication. Psychosis, bipolar disorder, and severe obsessive-compulsive disorder are among them, although such conditions may also warrant psychotherapy. Many other conditions, including phobias, panic attacks, and other forms of anxiety, as well as depression, respond well to psychotherapy. After an initial evaluation that includes a history of the current problem, a psychologist or psychiatrist will make a determination as to the best course of care; sometimes, medication is warranted to pave the way for therapy.

Both psychiatrists and psychologists increasingly recognize that mental health disorders arise from a complex interplay of factors, such as genetic vulnerability, physiological state, stress response, memory and cognition, social environment, lifestyle behaviors (e.g. sleep, nutrition, and exercise), and broader societal influences like socioeconomic conditions and racism.

How to find a qualified psychologist or psychiatrist

One of the most reliable ways to find a treatment provider is by word of mouth: Ask a friend or family member who has successfully sought help to make a recommendation based on the results of their search.
