What Does a Psychologist Do?

Psychologists are trained to assess, diagnose and treat emotional, behavioral and cognitive issues. So, what does a psychologist do more specifically? These professionals often use talk therapy and evidence-based techniques to help clients manage anxiety, depression and trauma. Though not medical doctors, psychologists hold advanced degrees and are licensed mental health professionals. Their focus is on behavior patterns and thought processes to support long-term emotional well-being.

What Does a Psychiatrist Do?

A psychiatrist is a medical doctor who diagnoses and treats mental health conditions. Unlike psychologists, psychiatrists attend medical school and complete a residency, which permits them to prescribe medication. Their treatment often blends medication management with therapy, especially for complex conditions like schizophrenia or bipolar disorder. Psychiatrists work in hospitals, clinics or private practice and often collaborate with other mental health professionals. Encompassing a clinical view of mental health, their training enables them to assess both psychological and physical symptoms.

Key Differences Between Psychologists and Psychiatrists

While both are trained mental health professions, the key difference between psychology and psychiatry lies in education, treatment approach and prescribing authority. The psychologist vs. psychiatrist distinction often centers on whether care involves therapy, medication or both.

Educational Path

Psychologists typically earn a psychology degree at the bachelor's level, followed by a doctoral degree (Ph.D. or Psy.D.); this can take eight to 12 years of higher education. Psychiatrists, in contrast, complete a bachelor's degree, attend medical school to become a licensed doctor and then undergo a four-year psychiatry residency — totaling around 12 years of training.

Prescribing Medication

Psychiatrists are licensed medical doctors who can prescribe medications to treat a wide range of mental health conditions. Psychologists, while trained in assessment and treatment, do not have prescribing authority. Medication management is a key area that separates the psychologist vs. psychiatrist scope of practice in clinical care.

Treatment Methods

Psychologists primarily utilize psychotherapy or talk therapy to help individuals understand and manage their thoughts, emotions and behaviors. Common approaches include cognitive behavioral therapy (CBT), psychodynamic therapy and humanistic therapy, each tailored to the client's specific needs.

Psychiatrists, as medical doctors, often focus on pharmacological treatments — prescribing medications such as antidepressants, antipsychotics and mood stabilizers to address mental health conditions. They may also incorporate psychotherapy, particularly for complex or treatment-resistant cases.

Conditions Treated

Both psychologists and psychiatrists address a broad spectrum of mental health conditions. Through therapeutic interventions, psychologists often treat issues such as:

Anxiety disorders

Depression

Phobias

Obsessive-compulsive disorder (OCD)

Post-traumatic stress disorder (PTSD)

Being medical doctors, psychiatrists manage more complex or severe conditions like schizophrenia, bipolar disorder and major depressive disorder, frequently utilizing medication as part of the treatment plan. The choice between a psychologist and a psychiatrist typically depends on the nature and severity of one’s mental health needs.

Work Environment

Psychologists work in diverse settings, including:

Private practices

Hospitals

Schools

Government agencies

Research institutions

Psychiatrists often practice in:

Hospitals

Private clinics

Academic health centers

Community mental health facilities

Both professions may collaborate with other healthcare providers to deliver comprehensive mental health care.

Referral Process

In mental health care, referrals often occur when a provider identifies that a patient's needs exceed their scope of practice. Psychologists may refer clients to psychiatrists for medication management, while psychiatrists might refer patients to psychologists for specialized therapy or once they are in a stable place. The psychologist will work on the psychotherapy and counseling aspect, freeing the psychiatrist to work with additional patients who need medication help. Thus, the referral process can work both ways. In addition, primary care physicians frequently initiate referrals to mental health professionals to ensure comprehensive treatment.

Licensing and Certification

Psychologists must complete a doctoral degree like a Ph.D. or Psy.D., accumulate supervised clinical hours and pass the Examination for Professional Practice in Psychology (EPPP) to obtain licensure. Psychiatrists, as medical doctors, must pass the United States Medical Licensing Examination (USMLE) and complete a psychiatry residency to become board-certified. Both professions require ongoing education to maintain licensure.

Focus of Care

Using therapy to support long-term mental health, psychologists emphasize behavioral patterns, emotional functioning and thought processes. Psychiatrists focus on the biological and neurological aspects of mental illness, often leveraging medication as a central form of treatment. This distinction shapes the psychologist vs. psychiatrist approach to patient care and clinical decision-making.

How Psychology and Psychiatry Overlap

While the difference between psychology and a psychiatrist is clear in training and scope, their roles often overlap in practice. Both mental health professionals focus on improving well-being and may collaborate on comprehensive treatment plans.

Focus on Mental Health

Psychologists and psychiatrists are both trained mental health professionals who focus on diagnosing and supporting individuals with emotional and psychological challenges. Whether through therapy or medication, each assumes a pivotal part in improving patient well-being and addressing complex mental health needs.

Client-Centered Approach

Psychologists and psychiatrists often use a client-centered approach, tailoring treatment to the individual’s needs, goals and preferences. Both professionals build trust and rapport to better understand their clients’ challenges — empowering them to take an active role in their mental health care and long-term recovery.

Collaborative Treatment

Psychologists and psychiatrists frequently work together to provide collaborative treatment plans, especially for individuals with complex mental health needs. A psychiatrist may handle medication while a psychologist offers therapy. This team-based approach ensures clients receive well-rounded care from both types of mental health professionals.

Use of Diagnostic Tools

Psychologists and psychiatrists utilize standardized diagnostic tools to assess mental health conditions. The Diagnostic and Statistical Manual of Mental Disorders (DSM-5) is a primary resource for both professionals. Psychologists often employ structured interviews and psychological assessments, whereas psychiatrists may incorporate medical evaluations alongside psychological tools to inform treatment decisions.

Ethical Guidelines and Licensing

Both psychologists and psychiatrists follow strict ethical standards and must be licensed. Psychologists adhere to the APA’s Code of Conduct, which covers confidentiality, competence and professionalism. Psychiatrists follow medical ethics guidelines from the American Psychiatric Association. Licensure requires advanced education, supervised experience and passing standardized exams.
