Psychiatric NP vs. Psychiatrist: Similarities and Differences
Psychiatric/mental health nurse practitioner (PMHNP) and psychiatrist are two closely aligned career paths that share many similarities. There are some key differences worth considering, too, though. Both are health professionals that assess and diagnose mental health conditions. They both must possess in-depth knowledge of medications used to treat these conditions, as well. However, the paths to these different professions are very different. What should nurses know about each career path?
Key Takeaways
- Psychiatric mental health nurse practitioners (PMHNPs) and psychiatrists both diagnose and treat mental health conditions, but they follow different education and training pathways in nursing and medicine.
- Becoming a PMHNP typically requires earning an advanced nursing degree such as an MSN or DNP and obtaining national certification, allowing nurses to specialize in psychiatric and mental health care.
- Psychiatrists are medical doctors (MD or DO) who complete medical school and residency training in psychiatry, preparing them to diagnose complex psychiatric conditions and provide medical treatment.
- Scope of practice, responsibilities, and prescribing authority may differ between PMHNPs and psychiatrists, with regulations for nurse practitioners varying by state.
- Both PMHNPs and psychiatrists play essential roles in expanding access to mental health care, helping patients manage conditions such as anxiety, depression, trauma-related disorders, and other psychiatric conditions.
What Is a Psychiatric Nurse Practitioner?
A psychiatric (mental health) nurse practitioner (PMHNP) is an advanced practice registered nurse (APRN) that specializes in the diagnosis and treatment of mental health disorders, including prescribing medication. Like all nurse practitioners, this career requires a four-year degree in nursing and advanced graduate studies. The additional education provides them with a Master of Science in Nursing (MSN) degree. They may also go on to earn a Doctor of Nursing Practice degree.
PMHNPs work in a variety of healthcare settings, including but not limited to:
- Outpatient clinics
- Hospitals
- Substance abuse treatment programs
- Emergency rooms
- Homeless shelters
- Correction facilities
In today’s changing healthcare culture, the PMHNP often fills the gaps in underserved populations needing mental health care. The Association of Nurse Practitioners reports that psychiatric/mental health is among the top five certifications sought by nurse practitioners.
What Is a Psychiatrist?
A psychiatrist is a medical doctor (MD or DO) that specializes in psychiatry. Their role involves the prevention, diagnosis, and treatment of mental health disorders, similar to a PMHNP. Unlike a nurse practitioner, though, a psychiatrist must obtain a four-year degree, attend and graduate from medical school, and complete a residency program.
PMHNP vs. Psychiatrist: Key Similarities
Both healthcare careers have similar day-to-day duties. They see patients with various emotional and mental health concerns for treatment. They both make diagnoses and prepare care plans for their patients.
As a nurse practitioner or a medical doctor, you can also do physical exams and order medical laboratory tests. Both use the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) as a basis for the diagnosis, testing, and treatments.
They also both use the same treatments to help manage psychiatric symptoms, including talk psychotherapy and medication. They may treat individuals, families, or groups of people. From a patient’s perspective, there are a few differences.
PMHNPs vs. Psychiatrists: Main Differences
While both psychiatric mental health nurse practitioners and psychiatrists diagnose and treat mental health conditions, their education, training, and scope of practice differ in several key ways.
| Category | Psychiatric Mental Health Nurse Practitioner (PMHNP) | Psychiatrist |
|---|---|---|
| Credentialing | APRN with PMHNP certification | MD or DO with psychiatry training |
| Education Level | MSN or DNP in psychiatric-mental health nursing | Medical degree plus psychiatry residency |
| Training Path | BSN → RN licensure → MSN/DNP → PMHNP certification | Bachelor’s degree → medical school → psychiatry residency |
| Scope of Practice | Assesses, diagnoses, treats, and may prescribe medication depending on state law | Diagnoses, treats, prescribes medication, and practices with physician-level authority |
| Job Duties | Mental health assessments, treatment plans, medication management, and patient support | Psychiatric evaluation, diagnosis, medication management, and complex care oversight |
Scope of Practice
In many states, a psychiatric nurse practitioner works under the supervision of a psychiatrist. A psychiatrist may review and sign documents and orders from PMHNPs. All states give PMHNPs prescription privileges, though certain states still require them to work under a medical doctor.
Education
Another significant difference is the educational path. First, a psychiatrist must attend medical school, which can take up to four years to complete, then obtain a Doctor of Medicine (MD) or Doctor of Osteopathic Medicine (DO). After graduating from medical school, they must get a license and then establish residency. The education process takes approximately eight years between college and medical school. They also must go through an additional three to seven years of clinical training in a residency program.
A PMHNP does not need to attend medical school to obtain their licensure. However, they must earn a Master of Science in Nursing degree, which typically takes a minimum of two years if they already hold a Bachelor of Science in Nursing. That means the path to become a PMHNP is about six years, during which time they will also do clinical training.
What Are the Job Duties for Each Role?
The job duties for a psychiatric nurse practitioner and a psychiatrist are also very similar. They both work closely with patients to develop treatment strategies designed to treat mental health issues.
Common job duties for both include:
- Obtain medical histories from patients
- Conduct psychological evaluations
- Determine the risk factors that may have an influence on a patient’s mental health
- Make treatment plans based on the requirements of the patient and the intended goals
- Prescribe medications and evaluate their efficacy
- Provide patient and caregiver education
There are additional duties that a psychiatrist may or may not perform, such as:
- Examine or co-sign documents and orders completed by mental health nurse practitioners
- Serve as an administrator at a psychiatric care facility or hospital ward
- Conduct research on mental health disorders and treatments
Although some of these tasks are not exclusive to psychiatrists, in general they tend to see more administrative work and research opportunities.
How Much Does Each Position Earn?
Salary ranges for psychiatric mental health nurse practitioners and psychiatrists can vary based on factors such as experience, geographic location, employer type, and specialty area. For the most accurate and up-to-date information, it is helpful to consult the U.S. Bureau of Labor Statistics (BLS), which publishes regularly updated wage and employment data for healthcare careers.

PMHNP vs. Psychiatrist: Which Career is Right for You?
A career as a PMHNP may be worth exploring if you:
- Want to advance from a nursing background into psychiatric care
- Are interested in assessing patients, managing treatment plans, and prescribing medication within your state’s scope-of-practice laws
- Want a shorter educational pathway than medical school
- Value a nursing-centered approach to patient care that combines mental health support with holistic treatment
A career as a psychiatrist may be a better fit if you:
- Want to attend medical school and complete residency training
- Are interested in the full medical model of diagnosing and treating complex psychiatric conditions
- Want the broadest physician-level scope of practice
- Are prepared for a longer and more intensive education path
Both roles can play an important part in supporting patients’ mental health. The right path may depend on your current educational background, the type of care you want to provide, and how you envision your future in mental healthcare.
