Which professional is typically qualified to diagnose and treat psychological disorders and provide therapy but does not prescribe medications?

• A. Clinical / Counseling Psychologist
• B. Psychiatrist
• C. Nurse Practitioner
• D. Social Worker

Answer: (A)

Clinical or counseling psychologists are trained to assess and diagnose psychological disorders through interviews, testing, and behavioral observation, and to provide psychotherapy using evidence-based approaches. They typically hold doctoral degrees and state licensure that authorizes diagnosis and treatment, but they do not usually prescribe medications. Prescribing rights are primarily held by psychiatrists (medical doctors who specialize in mental health) and, in many places, by certain nurse practitioners or physician assistants under medical supervision. Social workers can diagnose and provide therapy as well, but prescribing medications is not their standard role. Because the scenario describes a professional who can diagnose, treat, and provide therapy without prescribing meds, the psychologist is the best fit.
