What Do Psychologists Do? Roles, Training, and Treatment Approaches

If you've ever wondered what psychologists actually do, you're not alone. Many adults seeking mental health support aren't sure whether they need a psychologist, a psychiatrist, or another type of provider. Understanding the role of a psychologist — including their training, specialties, and treatment approaches — can help you make an informed decision about the care that's right for you.

What Is a Psychologist?

A psychologist is a mental health professional who holds a doctoral degree in psychology and specializes in understanding human behavior, emotions, and cognitive processes. Psychologists use evidence-based therapies and psychological assessments to help adults manage conditions such as depression, anxiety, trauma, and relationship difficulties. Unlike psychiatrists, psychologists in most states cannot prescribe medication — their primary tools are talk therapy, behavioral interventions, and psychological testing.

Types of Psychologists

Psychology is a broad field with several distinct specialties. The type of psychologist you see will depend on your specific needs and goals.

Clinical Psychologists

Clinical psychologists diagnose and treat a wide range of mental health disorders, including major depressive disorder, generalized anxiety disorder, obsessive-compulsive disorder, and personality disorders. They are trained to conduct comprehensive psychological evaluations and deliver structured psychotherapy. Many clinical psychologists work in private practice, hospitals, or integrated behavioral health settings.

Counseling Psychologists

Counseling psychologists tend to focus on everyday life stressors, adjustment issues, and interpersonal challenges rather than severe psychiatric illness. They help adults navigate career transitions, grief, relationship conflicts, and identity concerns. Their approach often emphasizes personal strengths and coping strategies.

Neuropsychologists

Neuropsychologists specialize in the relationship between the brain and behavior. They administer detailed testing batteries to evaluate memory, attention, executive function, and other cognitive domains. Neuropsychological assessments are frequently used to support diagnoses of ADHD, traumatic brain injury, dementia, and learning disabilities in adults.

Other Specializations

Additional areas of specialization include health psychology (managing chronic illness and health behaviors), forensic psychology (legal and criminal justice applications), and industrial-organizational psychology (workplace performance and employee well-being). Each specialty requires specific postdoctoral training and, in many cases, board certification.

Education and Training: PhD vs. PsyD

Becoming a licensed psychologist requires extensive education — typically 8 to 12 years beyond high school. After completing an undergraduate degree, aspiring psychologists earn a doctoral degree in psychology through one of two primary pathways.

  • PhD in Psychology (Doctor of Philosophy): This research-oriented degree emphasizes scientific inquiry, statistical methods, and original dissertation research. PhD programs are often housed in universities and prepare graduates for careers in both clinical practice and academic research.
  • PsyD in Psychology (Doctor of Psychology): The PsyD is a practice-focused degree that prioritizes clinical training and applied skills over research methodology. PsyD programs typically involve more supervised clinical hours and are designed for individuals who intend to work primarily as practitioners.

Both pathways require completion of a supervised predoctoral internship (usually one year) and postdoctoral supervised experience before a psychologist can sit for licensure exams. In Florida, psychologists must pass the Examination for Professional Practice in Psychology (EPPP) and meet state-specific requirements before they can practice independently.

Therapy Modalities Used by Psychologists

Psychologists are trained in a variety of therapeutic approaches. The modality a psychologist uses will depend on your diagnosis, treatment goals, and personal preferences.

Cognitive Behavioral Therapy (CBT)

CBT is one of the most widely researched and commonly practiced forms of psychotherapy. It helps adults identify and restructure distorted thought patterns that contribute to anxiety, depression, and other conditions. CBT is typically structured, time-limited, and goal-oriented, making it a practical choice for many individuals.

Dialectical Behavior Therapy (DBT)

Originally developed for borderline personality disorder, DBT has expanded to treat emotion dysregulation, chronic suicidal ideation, and self-destructive behaviors. It combines cognitive behavioral techniques with mindfulness-based strategies and focuses on four skill domains: mindfulness, distress tolerance, emotion regulation, and interpersonal effectiveness.

Psychodynamic Therapy

Psychodynamic therapy explores how unconscious processes, early life experiences, and recurring relational patterns influence current behavior. This modality tends to be longer-term and is particularly helpful for adults who want to develop deeper self-awareness and understand the root causes of persistent emotional difficulties.

Other Approaches

Psychologists may also use acceptance and commitment therapy (ACT), eye movement desensitization and reprocessing (EMDR) for trauma, motivational interviewing for behavioral change, and exposure therapy for phobias and OCD. Many psychologists take an integrative approach, drawing from multiple modalities based on what the evidence supports for your particular situation.

Psychological Assessment and Testing

One of the unique contributions psychologists make to mental health care is psychological testing. These standardized assessments provide objective data that support diagnostic accuracy and treatment planning.

Common types of psychological assessments include:

  • Cognitive and IQ testing: Measures intellectual functioning, processing speed, and problem-solving ability.
  • Personality assessments: Tools such as the MMPI-2 or PAI help identify personality traits and psychopathology.
  • Neuropsychological testing: Evaluates memory, attention, language, and executive function to detect cognitive impairment.
  • ADHD evaluations: Comprehensive testing that differentiates ADHD from other conditions with overlapping symptoms.
  • Diagnostic clarification: When a diagnosis is unclear, psychological testing can help distinguish between conditions such as bipolar disorder and major depression.

Testing results are typically compiled into a detailed report with diagnostic impressions and specific treatment recommendations. At Elevate Psychiatry, our team can use these findings alongside psychiatric evaluation to build a comprehensive treatment plan tailored to your needs.

Psychologists vs. Psychiatrists: Key Differences

One of the most common questions adults have when seeking mental health care is whether they should see a psychologist or a psychiatrist. While both professionals treat mental health conditions, there are important differences.

  • Prescribing authority: Psychiatrists are medical doctors (MD or DO) who can prescribe and manage psychiatric medications. In most states, including Florida, psychologists cannot prescribe medication.
  • Training background: Psychiatrists complete medical school and a psychiatry residency. Psychologists complete doctoral programs focused on psychology, therapy, and assessment.
  • Treatment focus: Psychiatrists often focus on medication management, while psychologists specialize in psychotherapy and psychological testing.
  • Session structure: Therapy sessions with a psychologist are typically 45 to 60 minutes. Psychiatric medication management appointments are often shorter, focusing on symptom monitoring and medication adjustments.

In many cases, the most effective treatment involves both a psychologist and a psychiatrist working together. A psychologist provides therapy while a psychiatrist manages medication — this collaborative model is considered the standard of care for conditions like moderate-to-severe depression, bipolar disorder, and PTSD.

When Should You See a Psychologist?

Consider scheduling an appointment with a psychologist if you are experiencing any of the following:

  • Persistent sadness, anxiety, or emotional distress that interferes with daily functioning
  • Difficulty managing stress, anger, or interpersonal conflicts
  • Unresolved grief or trauma
  • Concerns about attention, memory, or cognitive performance
  • A desire to better understand behavioral patterns and develop healthier coping strategies
  • Need for a formal psychological evaluation or diagnostic clarification

If you suspect that medication might also be needed, starting with a psychiatric evaluation can help determine whether therapy alone is sufficient or whether a combined approach would be more effective.

How Psychologists and Psychiatrists Work Together

Integrated care — where psychologists and psychiatrists collaborate on the same treatment plan — leads to better outcomes for many adults with mental health conditions. In this model, the psychologist provides ongoing therapy and shares progress updates with the psychiatrist, who adjusts medications as needed based on therapeutic gains and symptom changes.

For example, an adult with generalized anxiety disorder might see a psychologist weekly for CBT while also meeting with a psychiatrist monthly for medication management. The two providers communicate regularly, ensuring that treatment remains coordinated and responsive to the patient's evolving needs. At Elevate Psychiatry, we believe in this team-based approach to mental health care, where every aspect of your treatment is aligned toward your recovery goals.

Frequently Asked Questions

Can a psychologist prescribe medication?

In most states, including Florida, psychologists cannot prescribe medication. A small number of states and the military grant prescriptive authority to specially trained psychologists, but this is not the norm. If you need medication for a mental health condition, you would see a psychiatrist, psychiatric nurse practitioner, or another prescribing provider.

What is the difference between a psychologist and a therapist?

The term "therapist" is a broad, informal label that can apply to licensed clinical social workers, licensed mental health counselors, marriage and family therapists, and psychologists. A psychologist holds a doctoral degree (PhD or PsyD) and is trained to conduct psychological testing in addition to therapy, which distinguishes them from master's-level therapists.

How long does therapy with a psychologist typically last?

The duration of therapy varies depending on your diagnosis, goals, and the modality used. Structured treatments like CBT may last 12 to 20 sessions, while psychodynamic therapy can continue for months or years. Your psychologist will work with you to establish a timeline and regularly reassess whether your goals are being met.

Should I see a psychologist or a psychiatrist first?

It depends on your needs. If you're primarily interested in therapy, coping strategies, or psychological testing, a psychologist is a strong starting point. If you believe medication may be necessary — or if your symptoms are severe — beginning with a psychiatrist can help determine the right level of care. Many adults benefit from seeing both providers simultaneously.
