Psychotherapist vs Psychologist vs Psychiatrist: Who Does What

Start looking for help and you run straight into a wall of job titles. Psychotherapist vs psychologist, psychologist vs psychiatrist, plus LPC, LCSW, LMFT, PsyD and PMHNP. The roles overlap more than the letters suggest, and the differences that will actually affect your care are narrower than they look.

Three things separate these professionals: the training they completed, the license their state issued, and whether they can prescribe medication. Nearly everything else, including the therapy approach they use and how well you click with them, varies more between two individuals than between two categories.

This page walks through each role in United States terms, compares them in one table, gives practical advice on who to contact first, and closes with a short note for readers in the UK.

What is a psychotherapist?

Psychotherapist describes what a person does, not a specific degree or license. The National Institute of Mental Health defines psychotherapy as “a variety of treatments that aim to help a person identify and change troubling emotions, thoughts, and behaviors,” and it names psychiatrists, psychologists, social workers, counselors and psychiatric nurses as the professionals who deliver it. Any of them can accurately be called a psychotherapist. Whoever provides it, the American Psychological Association describes psychotherapy as a collaborative treatment based on the relationship between an individual and a psychologist.

That is why the word behaves differently from the others on this page. State law regulates specific licenses, not general descriptions. The U.S. Bureau of Labor Statistics notes that most states require licensure “for those who provide psychology services or use the title ‘psychologist’,” and every state licenses counselors, clinical social workers and marriage and family therapists under their own protected titles. The umbrella words “therapist” and “psychotherapist” are not tied to one of those licenses, and the rules on who may use them differ from state to state.

The practical consequence is simple: read “psychotherapist” as a job description, then look underneath it for the license. Cleveland Clinic gives the same advice in plainer terms: be sure “that any therapist you’re interested in seeing is a state-certified and licensed mental health professional and that they treat your area of concern.”

Good to know: State licensing boards publish online license verification, and it is free to use. Search the board’s site for the person’s name, confirm the license is active and check for disciplinary action. Our guide to checking credentials and licensing walks through it.

What is a clinical psychologist?

Psychologists typically hold an advanced degree in psychology, and for independent clinical practice that usually means a doctorate: a PhD, which leans toward research training, or a PsyD, which leans toward clinical practice. Licensure then adds supervised experience, which may include an internship or postdoctoral training, plus an exam. The required internship hours vary by state, and all states require continuing education to keep the license active.

Day to day, clinical psychologists “assess, diagnose, and treat mental, emotional, and behavioral disorders.” They conduct clinical interviews, deliver psychotherapy to individuals and groups, and administer formal psychological tests. That testing is the clearest difference from master’s-level therapists. If you need a structured assessment for ADHD, a learning disorder, autism, cognitive change after an injury or a diagnostic question nobody has answered yet, a psychologist is usually the right person.

Most psychologists cannot prescribe medication. A small number of states have passed prescriptive authority laws that let psychologists prescribe after additional graduate training in clinical psychopharmacology and a specialty exam. According to the APA chronology of those laws, New Mexico, Louisiana, Illinois, Iowa, Idaho, Colorado and Utah are among the jurisdictions that have done so. Outside those states, assume the answer is no.

Settings are broad: BLS employment data puts roughly a quarter of psychologists each in ambulatory healthcare services, schools, and self-employed practice.

What is a psychiatrist?

A psychiatrist is a medical doctor, “an M.D. or D.O., who specializes in mental health, including substance use disorders.” The path runs through a bachelor’s degree, four years of medical school and then residency. Physicians spend three to nine years in internship and residency depending on specialty; general adult psychiatry is a four-year residency, and child and adolescent psychiatry adds more. Every state licenses physicians, and most psychiatrists also choose board certification through the American Board of Psychiatry and Neurology.

The medical training changes what a psychiatrist can do with your case. They can order laboratory and psychological tests, evaluate whether a thyroid problem, medication interaction or other physical condition is driving your symptoms, prescribe and adjust medication, and in some settings provide treatments such as electroconvulsive therapy for severe, treatment-resistant illness.

Psychiatrists can and do provide psychotherapy, but many now work in a split-care model: they handle diagnosis and medication while a psychologist, counselor or social worker provides weekly therapy. If you want a psychiatrist who does both, ask on the first call.

Settings vary widely: private practices, clinics, general and psychiatric hospitals, community agencies, emergency rooms, courts and prisons, and government or military services. The American Psychiatric Association notes that about half of US psychiatrists maintain private practices and that many work in more than one setting.

What is a licensed professional counselor?

The title varies by state: Licensed Professional Counselor (LPC), Licensed Professional Clinical Counselor (LPCC), Licensed Clinical Professional Counselor (LCPC) and Licensed Mental Health Counselor (LMHC) all describe broadly the same qualification.

Mental health counselors typically need a master’s degree with an internship component, usually in counseling, psychology or a related field. All states require mental health counselors to be licensed, which means passing a national examination and completing supervised clinical work under the supervision of a licensed counselor. The number of supervised hours is set by the state, so it differs depending on where the person trained.

The exams come from the National Board for Certified Counselors, which administers the licensure examinations “used by all 50 states, the District of Columbia, Puerto Rico, the Virgin Islands, and Guam.” Depending on your state, a counselor will have passed the National Counselor Examination, the National Clinical Mental Health Counseling Examination, or both. The license itself always comes from the state board, not from NBCC.

Counselors cannot prescribe. They advise people on concerns “relating to alcoholism, addictions, or depression,” and in practice they handle much of the everyday caseload of anxiety, low mood, stress, grief and life transitions. You will find them in mental health centers, community health centers, private practice, inpatient and outpatient treatment programs, hospitals, correctional facilities and residential treatment.

What is a marriage and family therapist?

Marriage and family therapists work from a relationship lens. They diagnose and treat “cognitive, behavioral, or similar disorders in the context of couples and other relationships,” which means they will look at the pattern between people as well as the symptoms inside one person. They see individuals too, not only couples.

Entry requires a master’s degree. All states license MFTs, and the process involves a state-specified number of postdegree supervised clinical hours, a state-recognized exam, and annual continuing education. Some states add a jurisprudence exam on state law and ethics.

MFTs cannot prescribe. About a third work in offices of other health practitioners, with others in individual and family services, outpatient care centers, private practice and state government agencies, and many now offer telehealth.

If the problem you want to work on is mainly relational, this is the specialty built for it. See how the methods differ in our overview of couples therapy and family therapy.

What is a clinical social worker?

Clinical social workers typically hold a master’s degree in social work (MSW). All states license them, and licensure requires supervised clinical experience after graduation plus a clinical exam. You will see the credential written as LCSW, CSW or a similar state-specific title.

Their clinical scope is wide. Licensed clinical social workers diagnose and treat “mental, behavioral, and emotional problems,” and provide individual, group, family and couples therapy while helping clients build strategies to change behavior or cope with difficult situations.

What distinguishes the profession is its attention to the environment around the problem. A social worker is trained to treat your anxiety and also to notice that the housing situation, the benefits appeal or the school’s refusal to provide accommodations is part of what keeps the anxiety going. That is genuinely useful when your difficulties are tangled up with money, paperwork or caregiving.

Clinical social workers cannot prescribe. They work across state and local government, individual and family services, outpatient healthcare, hospitals, schools and private practice, which makes them among the easiest therapists to find.

Who else can prescribe for mental health

Two other prescribers are worth knowing about, because psychiatry wait times can be long.

Psychiatric mental health nurse practitioners (PMHNPs) are advanced practice registered nurses who typically hold at least a master’s degree in an advanced practice nursing field and may specialize in psychiatric and mental health care. In most states they can prescribe medications, order tests and diagnose, though the scope of independent practice varies by state. Many people get their medication care from a PMHNP.

Primary care physicians are the other route. They are licensed to prescribe, they know your medical history, and they can screen for depression and anxiety, check for physical causes and refer you onward. For many people this is the shortest path to a first appointment.

Side-by-side comparison

Which professional should you see first?

Match the starting point to the problem rather than to the prestige of the title.

1. You want to talk something through. For anxiety, depression, stress, grief, relationship strain or a difficult life change, start with a master’s-level clinician (LPC, LCSW or LMFT) or a psychologist. They are the most widely available and usually the least expensive option.
2. You are not sure what is wrong, or previous therapy did not help. A clinical psychologist can run a proper assessment and give you a clearer diagnostic picture before anyone commits to a treatment plan.
3. Medication is on the table. If symptoms are severe, if you have a diagnosis such as bipolar disorder or psychosis, or if you already take psychiatric medication, see a psychiatrist or a psychiatric nurse practitioner. Medication and therapy are not competitors; NIMH notes that psychotherapy “can be used as an alternative to or alongside medication and other treatment options.”
4. The problem lives between people. A marriage and family therapist, or any therapist trained in couples work, will get further than individual therapy alone.
5. You have no idea where to start. Book with your primary care doctor. A screening visit can rule out physical contributors such as thyroid problems or anemia, and often produces a referral.

Once you have a shortlist, the next questions are about fit, cost and availability rather than credentials. Our guides on how to choose a psychotherapist, therapy costs and lower-cost options, what happens in a first therapy session and the main types of psychotherapy cover that ground.

If you are in crisis or thinking about suicide, do not wait for an appointment. In the United States you can call or text 988 to reach the 988 Suicide and Crisis Lifeline, which is free, confidential and available 24 hours a day. Our crisis help page lists more options.

A note for readers in the UK

The dividing lines sit in a different place. The Health and Care Professions Council regulates practitioner psychologists, and titles such as clinical psychologist and counselling psychologist are protected by law: to use one, a person must be registered with the HCPC. Psychiatrists are medical doctors, as in the United States.

Counsellor and psychotherapist are not regulated in the same statutory way. Instead, practitioners join voluntary registers, and the stronger of those registers are accredited by the Professional Standards Authority: the British Association for Counselling and Psychotherapy and the UK Council for Psychotherapy both hold one. The NHS advice on talking therapies is to make sure a private therapist is registered with a professional organisation accredited by the PSA. For many common problems you can also refer yourself to NHS talking therapies without speaking to a GP first.

Other countries draw the lines in their own places again, through national or provincial regulators rather than state boards. The habit that travels everywhere is the same: find out which body holds the licence or registration for that title where you live, then check that the person is actually on it.
