Therapist vs. Psychologist: Understanding the Differences in Roles in Our Profession

Even experienced mental health professionals sometimes find it challenging to explain the differences between a therapist and a psychologist. This confusion can create misunderstandings that affect teamwork, public awareness, and ethical clinical practice. When we clarify these distinctions, we help create a more unified and effective mental health field.

Although people often use "therapist" and "psychologist" interchangeably, these titles represent different professional roles with unique training backgrounds. Simply put, all psychologists can offer therapy, but not all therapists are licensed psychologists. Let's explore the key differences that set these roles apart.

What distinguishes a therapist from a psychologist? The answer involves their educational paths, licensing requirements, and scope of practice. Understanding these factors helps mental health professionals communicate their roles more effectively to clients and colleagues, improving the quality of care.

Educational Pathways: Where Training Begins to Diverge

• Therapists: Usually masters-level clinicians (LMFT, LPCC, LCSW, etc.) with 2-3 years of graduate study, but can also include licensed psychologists. However, for the sake of this article, the term ‘therapist’ will refer to masters level clinicians only.
• Psychologists: Doctoral-level (PhD, PsyD, EdD), with 5-7+ years of schooling, including dissertation and internship. PsyD degree programs tend to have a clinical focus, whereas PhD programs are traditionally rooted in research along with clinical work. 

(e.g., BBS vs. Board of Psychology in California) Notably, the governing licensing bodies that oversee these titles vary by state and are often separate entities, each with its own requirements, regulations, and scope of practice guidelines. For example, in California, the Board of Behavioral Sciences oversees Masters level clinicians, including LPCCs, LCSWs, and LMFTs, whereas the Board of Psychology oversees all psychologists. 

Scope of Practice and Specializations

While both therapists and psychologists provide mental health services, their scope of practice and areas of specialization can differ significantly. Knowing these differences helps clients find the most appropriate provider for their needs and allows for better collaboration among mental health professionals.

Therapists, such as licensed marriage and family therapists (LMFTs), licensed professional clinical counselors (LPCCs), and licensed clinical social workers (LCSWs), usually focus on providing talk therapy, which includes creating treatment plans, and applying clinical interventions. They work with individuals, couples, families, or groups to address a wide range of mental health concerns, including anxiety, depression, relationship issues, and trauma. Therapists may specialize in specific approaches, such as cognitivebehavioral therapy (CBT), dialectical behavior therapy (DBT), or emotionally focused therapy (EFT).

On the other hand, psychologists who hold doctoral degrees in psychology (PhD or PsyD), have a broader scope of practice that includes not only providing therapy but also psychological testing, research, and diagnostic assessments. They are trained to administer and interpret standardized tests, such as intelligence tests, personality assessments, and neuropsychological evaluations. Psychologists may focus on various subfields, such as clinical psychology, counseling psychology, or neuropsychology, allowing them to provide targeted interventions and assessments for specific populations or mental health concerns.

• Examples of specialty areas for therapists: Trauma-focused CBT, family systems therapy, or substance abuse counseling
• Examples of specialty areas for psychologists: Neuropsychological assessment, forensic psychology, or health psychology

Assessment, Testing, and Diagnosis

One key difference between therapists and psychologists lies in their ability to conduct formal psychological testing. Licensed psychologists possess the training and expertise to administer, score, and interpret standardized tests that assess various aspects of mental health and cognitive functioning, such as:

• Intelligence tests (IQ tests): Measure cognitive abilities and capabilities
• Personality assessments: Explore the genetic, environmental, and social components of personality
• Neuropsychological evaluations: Assess conditions like traumatic brain injury, memory disorders, or neurocognitive disorders

These tests offer valuable insights for diagnosing mental health conditions, developing personalized treatment plans, and monitoring progress throughout therapy. Psychologists use these assessments in settings like clinical practices, hospitals, schools, and career counseling centers.

Therapists, on the other hand, typically rely on clinical interviews, behavioral observations, and screening tools to assess their clients' mental health. While they may use some standardized questionnaires or scales, they do not have the same level of training in administering and interpreting formal psychological tests.

Therapists and psychologists can effectively collaborate on complex cases, combining their unique skills and perspectives. Therapists can share insights from their therapeutic work with clients, while psychologists contribute their expertise in testing and assessment. This collaboration ensures a thorough understanding of the client's needs and informs the development of targeted treatment plans using evidence-based approaches.

Work Settings and Roles

Therapists and psychologists often find themselves working in similar settings, though there are key differences in their roles and work environments. Knowing these distinctions can guide mental health professionals in identifying the best fit for their skills and interests and also help clients understand what to expect when seeking care.

Therapists, such as LMFTs, LPCCs, and LCSWs, typically work in:

• Private practice: Offering individual, couples, or family therapy, either solo or within a group practice
• Schools: Providing counseling or social work services to students, staff, and families in K-12 or higher education settings
• Community clinics and nonprofits: Serving diverse groups, often prioritizing accessibility and affordability
• Employee Assistance Programs (EAPs): Delivering short-term counseling and referrals for employees dealing with personal or work-related issues
• Hospitals: Providing inpatient or outpatient therapy services, usually as part of a multidisciplinary team

Psychologists work in many of the same settings as therapists but can also be found in:

• Academic and research institutions: Engaging in research, teaching courses, or supervising graduate students
• Forensic settings: Conducting evaluations and offering expert testimony in legal cases, such as  competency hearings
• Veterans Affairs (VA) systems: Providing assessment, therapy, and other mental health services to military veterans and their families

Both therapists andpsychologists can choose to engage in further specialized  roles that extend beyond direct clinical work, such as:

• Consultation: Offering guidance and expertise to organizations, schools, or healthcare systems
• Supervision: Overseeing the clinical work of graduate students, postdoctoral fellows, or unlicensed professionals
• Teaching: Educating future mental health professionals in graduate programs or continuing education courses

Prescriptive Authority and Medical Integration

While both therapists and psychologists play important roles in mental health care, a key difference lies in their ability to prescribe medication. In most states, neither therapists nor psychologists have the authority to prescribe psychiatric medications, such as antidepressants or antipsychotics. This responsibility typically falls to medical professionals, such as psychiatrists, psychiatric nurse practioner, or primary care physicians.

However, there are some notable exceptions. As of 2025, several states, including New Mexico, Louisiana, Illinois, Iowa, Idaho, Colorado, and Utah, have granted prescriptive authority to specially trained psychologists. These psychologists must undergo rigorous postdoctoral training in psychopharmacology, which includes extensive coursework and supervised clinical practice. This additional education equips them with the knowledge and skills necessary to safely and effectively prescribe psychiatric medications.

• Eligibility: Psychologists must hold a doctoral degree and complete a postdoctoral master's degree in clinical psychopharmacology or a similar program.
• Training requirements: Specific requirements vary by state but typically involve 400-450 hours of classroom instruction and a supervised practicum, followed by a national examination.

Despite the trend of granting prescriptive authority to psychologists in select states, the practice remains controversial. Some argue that psychologists lack the comprehensive medical training of psychiatrists, who are licensed physicians with expertise in diagnosing and treating mental health disorders using both therapy and medication.

Regardless of prescriptive authority, integrative care teams hold significant value. Therapists, psychologists, psychiatrists, and primary care physicians each bring unique skills and perspectives to the table. By working together, these professionals can provide a holistic approach to mental health treatment, ensuring that clients receive the most appropriate and effective care for their individual needs. As the mental health landscape continues to change, professionals must stay informed about the latest developments in prescriptive authority and advocate for policies that prioritize client well-being and expand access to quality care.

Public Perception and Professional Identity

Despite the increasing awareness of mental health issues, public misconceptions about therapists and psychologists still exist. One common misunderstanding is the interchangeable use of these titles, with people often asking, "Are you a psychologist?" when they actually mean therapist. This confusion can lead to unrealistic expectations and misunderstandings about the roles and capabilities of mental health professionals.

• Responsibility to educate: Mental health professionals need to clarify their roles, qualifications, and scope of practice to clients and the broader community. This education helps to dispel myths, reduce stigma, and ensure that people seek the most appropriate care for their needs.
• Honoring all paths: Recognizing and respecting the diverse training backgrounds and approaches of mental health professionals is important. Whether someone is a therapist or a psychologist, their expertise and clinical effectiveness may lie in their post-graduate training, lived experience, or relational style.  
• Building trust and reducing stigma: When mental health professionals openly discuss their roles and work together effectively, it builds trust with clients and the public. This transparency and mutual respect among professionals can help to reduce the stigma surrounding mental health care and encourage more people to seek support when needed.

As the mental health field continues to change, professionals should actively educate the public about the differences between therapists and psychologists. By promoting a more accurate understanding of these roles, professionals can help individuals make informed decisions about their care and reduce confusion or stigma surrounding mental health services.

Conclusion: Different Titles, Shared Purpose

As we've looked into the key differences between therapists and psychologists, it's clear that both roles play important parts in the mental health field. While their training, scope of practice, and areas of specialization may differ, therapists and psychologists share a common goal: to support the well-being of their clients and promote healing.

• Collaboration and mutual respect: Therapists and psychologists should work together, recognizing and valuing the unique contributions each brings. Collaboration helps create a more complete understanding of clients' needs and allows for the development of targeted evidence-based treatment plans.
• Knowing your lane and advocating for your scope: Mental health professionals should clearly understand and communicate their own roles, qualifications, and scope of practice. They must also be willing to advocate for their profession and educate others about the importance of their work. This clarity and advocacy help ensure that clients receive the most appropriate and effective care for their needs.
• A shared commitment to healing: Ultimately, what unites therapists and psychologists is their dedication to helping others and promoting mental well-being. Despite their different titles and training paths, they are connected by a common purpose: to alleviate suffering, foster personal growth, and empower individuals to lead fulfilling lives.

As the mental health landscape continues to evolve, it is important that therapists and psychologists maintain open lines of communication, engage in ongoing collaboration, and adapt to the changing needs of their clients and communities. By working together and using their unique strengths, these professionals can create a more accessible, effective, and compassionate mental health care system for all.
