Psychologists study the mind and behavior to support people with mental health conditions. They might specialize in different subfields, such as clinical or forensic psychology.
This article provides an overview of what psychologists do, the different types of psychologists, and how they can help.

Psychologists have gone through clinical and academic education in psychology to understand the mind and behavior.
They provide services to people with mental health conditions and those going through difficult or distressing times.
People might receive different services from a psychologist, depending on their area of specialty.
For example, a psychologist might help someone with symptoms of depression or anxiety. The person may be dealing with specific issues, such as anger problems or bereavement.
Psychologists use a variety of methods to help people in different situations. A common approach is providing psychotherapy, which is a type of talk therapy to help people cope with symptoms and improve their well-being.
In some cases, a psychologist will work with other healthcare professionals to provide treatment. For example, they might work with a family doctor or psychiatrist, who can prescribe medication.
Psychologists can work in private practices or a variety of other locations, including hospitals or schools. Some psychologists also conduct diagnostic assessments and academic and clinical research.
There are many areas in which a psychologist might specialize.
According to the American Psychological Association (APA), recognized specialties of psychology include the following:

- helping people lose weight or live a healthful lifestyle
- addressing problems in people with chronic health conditions, such as heart disease

Psychiatrists have a different educational background than psychologists. They are medical doctors who have chosen to specialize in psychiatry rather than another area of medicine.
They have the authority to prescribe medications to people with mental health conditions.
On the other hand, psychologists are not medical doctors and are unable to prescribe medication.
Psychologists typically have a doctoral degree that involves at least 4–6 years of full-time education and training after an undergraduate degree.
Psychologist training can vary depending on the specialty. For example, the training may focus on statistics, biology, or social factors.
Psychologists must obtain a license to practice, which requires national and state-specific examinations.
People looking for a psychologist can consult their family doctor. A doctor will be able to assess a person’s needs and suggest the right kind of psychologist.
It is also possible to locate a psychologist online. For example, the APA provide an online search tool for finding local psychologists.
Anyone who is experiencing persistent emotional, behavioral, or cognitive problems could benefit from seeing a psychologist. Parents or caregivers who suspect that their child has ADHD or ASD can also take them to these specialists for an evaluation.
Some examples of signs that it may be helpful to see a psychologist include:
- feeling anxious on a regular basis
- experiencing overwhelming feelings of sadness or helplessness
- having difficulty with everyday challenges or work
- using drugs or alcohol to cope
- having suicidal thoughts
- experiencing abuse or other trauma
