It can be confusing what the difference is, because there is often overlap in what both of these professionals do. They both specialize in mental health. Their training is different, though. Also, the way a psychologist and a psychiatrist work can be very different.
Training
Psychologist: Psychologists usually have a Ph. D (“Doctor of Philosophy”) in psychology or a Psy.D. (“Doctor of Psychology”). Their training focuses on studying human behavior, emotions, and cognitive processes. Psychologists also are often trained extensively in psychological assessment, research methods, and therapeutic interventions. They do not attend medical school. Instead, their training emphasizes non-medical approaches to mental health.
Psychiatrist: Psychiatrists are medical doctors (MDs or DOs) who specialize in mental health and have completed medical school. They undergo a residency in psychiatry, where they learn about diagnosing and treating mental illnesses, often with a strong emphasis on the biological and neurological underpinnings of these disorders. Their medical training allows them to understand the interplay between physical and mental health. This is important, because the physical health often can impact the mental health, allowing for a more holistic approach to mental health.
Scope of Practice Psychologist:
Psychologists usually provide psychotherapy, also known as talk therapy, to help individuals manage and overcome mental health challenges. They use evidence-based therapeutic approaches such as cognitive-behavioral therapy (CBT), psychodynamic therapy, and humanistic therapy. Psychologists can also administer and interpret psychological tests to assess intelligence, personality traits, or emotional functioning.
Psychiatrist: Psychiatrists focus on diagnosing and treating mental illnesses through medical interventions, including prescribing medication. Their ability to prescribe psychotropic drugs, such as antidepressants, antipsychotics, or mood stabilizers, distinguishes them from psychologists. Psychiatrists often treat more severe or complex mental health conditions, such as schizophrenia, bipolar disorder, and major depressive disorder, and may combine medication with psychotherapy (like I do), or other psychiatrists refer patients to psychologists for additional support.
The Best of Both Worlds
I like to combine both: As a medically trained physician (M.D), I have the medical knowledge required to safely prescribe medications for mental health. Also, as a psychoanalyst I have been extensively trained in psychotherapy and am proficient in psychoanalysis.
