Since psychiatrists and psychologists work together in many situations, their treatment plans can overlap. This can cause some confusion when looking for treatment for a mental health disorder or therapy. There are distinct differences between the two that are important to understand when considering which type of help you should look for. Keep reading to learn more about these differences.

What is a psychologist?

A licensed psychologist in the U.S. generally has a doctoral degree, such as a PsyD or PhD, along with supervised clinical training and licensure. It typically takes many years of schooling and training to become a psychologist. A psychologist will either have a PsyD (Doctor of Psychology) or a Ph.D. (Doctor of Philosophy) and have studied behavioral therapy, cognitive therapy, psychological therapy, treatments, psychological research, and personality development. Those with a Ph.D. will also have an extensive amount of training in research. Therefore, these professionals have extensive knowledge in the field.

What do psychologists do?

Psychologists use assessments, evaluations, and tests to determine their client's needs, and they have the necessary training to administer treatment. They can make diagnoses with these assessments and can provide the therapy needed in most cases. The psychologist works to understand their client's characteristics, personality, cognitive abilities, strengths, and weaknesses.

Treatments that psychologists provide

Some of the treatments that psychologists often provide include:

  • Psychoanalysis: a form of talk therapy that helps patients and psychologists discover thoughts and emotions buried in the subconscious
  • Gestalt therapy: psychotherapy that helps with relationship problems and low self-esteem, anxiety, and depression
  • Cognitive-behavioral therapy, or CBT: a form of psychotherapy that helps change the way patients behave by helping them change their thought patterns.
  • Cognitive analytic therapy, or CAT: helps clients figure out what may have caused their current mental health problems, such as overly controlling parents or neglect.

What is a psychiatrist?

A psychiatrist is a medical doctor that specializes in mental health conditions. They are either M.D.s or D.O.s, and one of the main differences between them and psychologists is that a psychiatrist can prescribe medication when clinically appropriate. Thus, they must attend medical school to learn general medicine before completing specialized psychiatry training. Their post graduate training typically incudes four years in a medical training program as a resident, which includes working in various medical settings including a hospital psychiatric unit. A psychiatry resident will see various patients, from children to adults, with many different mental health conditions.

Like psychologists, psychiatrists sometimes specialize in one or few mental health issues or presentations. For example, some may only treat children and adolescents, while others treat mainly elderly patients. Others may be specially trained in working with brain injuries or other diseases, so they must have a high level of expertise in that area.

What do psychiatrists do?

No matter which type of psychiatrist one chooses to be, they are trained as medical doctors. They often focus on diagnosis, medication management, and medical aspects of care, and some also provide psychotherapy. Some of the treatments that a psychiatrist may use include:

  • Medication management, which may include antidepressants or anti-anxiety medications when appropriate based on a full evaluation.
  • Electroconvulsive therapy, or ECT, the use of electrical currents in the brain.
  • Light therapy, artificial sunlight treatments to treat seasonal affective disorder.
  • Transcranial magnetic stimulation, or TMS, the use of a magnetic coil to send magnetic pulses to the brain to treat depression.
  • Vagus nerve stimulation, or VNS, the use of electrical stimulation to the vagus nerve to treat major depression or epilepsy when other treatments have not worked.

Psychiatrists and psychologists working together

Although many psychiatrists focus more on medication management, some also provide psychotherapy, and many work collaboratively with psychologists or therapists. In some instances, a psychiatrist will send a patient to a psychologist because their issue may be better served with psychotherapy or counseling. For example, if you and your significant other have relationship issues, a psychiatrist may refer you to a psychologist or relationship therapist for psychotherapy.

Consider online therapy as a convenient option when you need to talk to a psychiatrist or psychologist about mental health conditions

Couples counseling or therapy can be done by many mental health professionals, including psychologists, therapists, or counselors. What can you do if life feels too busy for therapy? With online couples counseling, you and your partner can be at home together or in two different places. For example, if your significant other is at work and you are at home, online therapy can make the logistics of couples therapy more manageable. With online therapy, you may have more scheduling flexibility and may also be able to message your therapist between sessions, depending on the platform.
