Definition
A psychologist in clinical practice is typically a doctoral-level clinician (PhD or PsyD) trained in psychological assessment and the practice of evidence-based psychotherapy. In most U.S. states psychologists don't prescribe medication, although a small number of states allow medical psychologists with additional training to prescribe.
What it can feel like
Visits with a psychologist tend to focus on talk therapy, structured treatment protocols such as cognitive behavioral therapy, and, in some practices, formal psychological testing for diagnostic clarification. Sessions are usually 45 to 50 minutes and occur at a regular cadence. The work is collaborative and involves practice between sessions.
Why it happens
Doctoral training in clinical psychology emphasizes the science of thinking, behavior, and emotion, and the clinical methods that follow from it. Psychologists often work alongside psychiatrists when both medication and therapy are part of treatment, with clear communication about the overall plan. The choice between a psychologist, a master's-level therapist (LCSW, LPC, MFT), and a psychiatrist depends on what's needed: assessment, structured therapy, medication, or some combination.
When to see a clinician
A psychologist is the right referral when therapy is the treatment of focus, when formal psychological testing may be helpful, or when an in-depth assessment of cognitive or personality functioning would clarify the picture. Many people benefit from working with both a psychologist and a psychiatrist.
