Psychology vs. Psychiatry: What's the Difference?
When you're looking for mental health support, you might come across both psychologists and psychiatrists—two terms that sound similar but refer to very different professions. Understanding the difference between psychology and psychiatry can help you find the right kind of care for your needs.
What Is Psychology?
Psychology is the scientific study of the mind, behavior, and emotions. Psychologists are trained professionals who often help people through talk therapy (also called psychotherapy), but their training also includes research, testing, and behavior change techniques.
Psychologists hold a doctoral degree in psychology—either a Ph.D. (Doctor of Philosophy) or Psy.D. (Doctor of Psychology). They are experts in mental processes, emotional functioning, and human behavior. Some work in clinical settings with patients, while others work in academic or research roles.
Clinical psychologists can:
- Provide therapy for issues like anxiety, depression, trauma, and more
- Conduct psychological assessments and testing (e.g., for ADHD, learning disabilities, personality, etc.)
- Offer evidence-based treatments like Cognitive Behavioral Therapy (CBT), Dialectical Behavior Therapy (DBT), and others
Psychologists do not prescribe medication in most states, but they may work alongside psychiatrists or nurse practitioners who do.
What Is Psychiatry?
Psychiatry is a branch of medicine focused on diagnosing and treating mental health disorders from a medical and biological perspective. Psychiatrists are medical doctors (MDs or DOs) who specialize in mental health.
Because they attend medical school and complete a residency in psychiatry, psychiatrists are uniquely qualified to understand how mental health symptoms can relate to physical conditions, brain chemistry, or the effects of medication.
A psychiatric nurse practitioner—often called a Psychiatric-Mental Health Nurse Practitioner (PMHNP)—is an advanced practice registered nurse who specializes in mental health care. They are licensed and trained to assess, diagnose, and treat individuals with mental health conditions across the lifespan.
PMHNPs hold at least a master's or doctoral degree in nursing, and they complete specialized training in psychiatry and behavioral health. They are board-certified to provide psychiatric care in a variety of settings, including private practices, hospitals, community clinics, and telehealth platforms.
Compared to psychiatrists: PMHNPs and psychiatrists have overlapping roles in diagnosing and prescribing, but PMHNPs come from a nursing background while psychiatrists are medical doctors. Both are qualified to prescribe medication and manage psychiatric care.
Psychiatrists and PMHNPs can:
- Diagnose mental health disorders
- Prescribe medications (e.g., antidepressants, mood stabilizers, antipsychotics)
- Offer brief supportive therapy or referrals for psychotherapy
- Manage complex or severe mental health conditions
Key Differences at a Glance:
| Feature | Psychology | Psychiatry |
|---|---|---|
| Education | Ph.D. or Psy.D. in Psychology | MD, DO or PMHNP (medical doctor or advance practice nurse) |
| Training Focus | Behavior, emotions, and therapy | Mental illness diagnosis & medication |
| Prescribes Medication | No (except in a few U.S. states) | Yes |
| Provides Therapy | Yes (often primary focus) | Typically no |
| Uses Psychological Testing | Yes | No |
| Approach | Talk therapy, testing, behavioral tools | Medical treatment |
Which One Do You Need?
The best option depends on your situation:
- If you're looking to understand your emotions, work through life stressors, or change patterns of thinking or behavior, a psychologist may be a great fit.
- If you're struggling with symptoms that may need medication—like severe depression, bipolar disorder, psychosis, or ADHD—a psychiatrist or advanced practice nurse may be the right choice.
In many cases, people benefit from both. For example, someone might see a psychiatrist for medication management and a psychologist for therapy and psychological support simultaneously. These professionals often collaborate to provide comprehensive care.
Final Thoughts
Though psychology and psychiatry both focus on mental health, they do so in distinct and complementary ways. Psychologists are experts in human behavior and talk-based therapy, while psychiatry focuses on prescribing and monitoring medication.
Whatever path you choose, what matters most is getting the support you need. Mental health is just as important as physical health—and reaching out for help is a strong and meaningful step toward feeling better.
