In-Depth Differences

A psychologist is a social scientist who is trained to study human behavior and mental processes. Psychologists can work in a variety of research or clinical settings. Psychology degrees are available at all levels: bachelor’s, master’s, or doctorate (PhD or PsyD). Advanced degrees and licensing are required for those in independent practice or who offer patient care, including clinical, counseling and school psychologists.

PhD programs in clinical psychology emphasize theory and research methods and prepare students for either academic work or careers as practitioners. The PsyD, which was created in the late 1960s to address a shortage of practitioners, emphasizes training in therapy and counseling. Psychologists with either degree can practice therapy but are required to complete several years of supervised practice before becoming licensed.

A psychologist will diagnose a mental disorder or problem and determine what’s best for the patient’s care. A psychologist often works in tandem with a psychiatrist, who is also a medical doctor and can prescribe medication if it is determined that medication is necessary for a patient’s treatment. Psychologists can do research, which is a very important contribution academically and clinically, to the profession.

A therapist is a broader umbrella term for professionals who are trained—and often licensed—to provide a variety of treatments and rehabilitation for people. Therapists can be psychoanalysts, marriage counselorssocial workers and life coaches, among other specialties. A therapist’s goal is to help patients make decisions and clarify their feelings in order to solve problems. Therapists provide support and guidance, while helping patients make effective decisions within the overall structure of support. When selecting a therapist, their education, licensing and professional credentials should be essential considerations.
